Motoblock does not start in frost
Why the car won’t start “cold”.
The main reasons why a car does not start well when cold are:
The second, common case. this is a low level of sparking.
This can happen for the following reasons:
- if spark plugs fail;
- in case of violation of the electrical connections of the ignition system;
- in case of failure of the ignition coils
In this case, it is necessary to identify the causes and eliminate the source of the malfunction that prevents the vehicle from starting with a cold engine.
It is enough to replace the spark plugs and check all the connections of the ignition system.
Poor quality gasoline
There is no narrow-minded method for assessing fuel quality. We have to use indirect signs, for example, a bad plant after refueling at an unchecked gas station. At the same time, while your car does not start, there is a great chance to plant the battery, “kill the candles”, clog the injector and even destroy the engine in case of improper detonation.
If it does not start well on a hot engine, the reason is probably an unsuccessful refueling. The solution to this problem is the use of additives in the gas tank, which improve the basic performance of gasoline.
To protect yourself from the consequences of refueling with low-quality fuel and to keep the injector in good condition, we recommend that you always keep on hand a long-term Langzeit Injection Reiniger injector cleaner for gasoline engines and a long-term diesel additive Langzeit Diesel Additiv for diesel engines.
It is recommended to use these additives in fuel when refueling at untested gas stations, as well as on highways.
Weak dead battery
This factor of poor engine starting is widespread! Frost leads to an accelerated discharge of batteries.
- the vehicle can be started by replacing the battery with a charged one, or charge the existing one;
- if the automaker allows it, then you can “light a car”. In this case, be sure to take into account the sequence of actions specified in the operating instructions.
Advice! If you are in doubt whether the vehicle will start in frost due to a “dead” battery, then you should understand that the battery will have the strongest charge only when you first try to start the engine. From the moment the machine is opened with a “key fob”, the system starts processes that consume electricity, so it is important to act quickly!
The most likely to start a vehicle with a dead battery is:
- Standing next to the car, open it and immediately sit in the driver’s seat, turning on the ignition.
- Wait 2-4 seconds to activate all vehicle systems.
- Turn the ignition key further by activating the starter and starting the engine.
Air filter problems
In winter, with large temperature differences, a possible cause of problems such as icing of the air filter. Lack of air is also a reason that prevents the car from starting. In this case, it is recommended to replace the air filter immediately at the first sign of malfunction. The procedure is quite simple and does not require special skills.
IMPORTANT! One of the key factors provoking a poor cold start of a vehicle may be an incorrectly selected engine oil. If you have filled in oil with a viscosity of 10W-XX and higher, and severe frosts hit, then the oil thickens and its pumpability in a cold system drops sharply, which leads to significant engine wear at start; as a result. the car will not start.
In winter, it is important to choose only high-quality oils from trusted manufacturers, as this guarantees the compliance of the oils with the declared parameters of “behavior” in the cold.
Gasoline engine starts poorly
A gasoline engine differs from a diesel engine primarily in the presence of spark plugs. Not to be confused with glow plugs. That is, in order for the gasoline engine to work as expected, it is necessary to ignite the fuel-air mixture with a spark from a spark plug.
The engine does not start well: causes and solutions to the problem
If the car does not start, you need to immediately determine the reasons that negatively affect the starting of the engine. And for this it is necessary to systematize and reduce the number of options for engine operation problems. Does the motor work in a problem “cold” or “hot”? Does the engine run on gasoline or diesel? Answering these questions will help reduce the causes of poor engine performance.
Why does the engine start badly? Need to understand the root cause!
With half a turn it is possible to start only perfectly tuned types of engines with a carburetor or mechanical injection of the first generations, which do not have any electronics in their composition. In all other cases, the engine control unit must interrogate the sensors and, after analyzing their signals, give a command to supply a spark.
This takes several turns of the engine with the starter. In case of malfunctions, the process is delayed, which greatly irritates the owner of the car. In such cases, there is a problem with starting the vehicle. It is necessary to separate the factors that negatively affect the start of a gasoline and diesel engine.
Advice for starting diesel motoblocks in winter
Use suitable seasonal oils
Keep your diesel engine in top shape all year long with synthetic diesel oil. Earlier we talked about what oils are and how to choose the right one for your walk-behind tractor. Winter oil is formulated for lower temperatures and contains additives that prevent rapid freezing in the cold. If you use summer oil during the cold winter months, you may have trouble starting the engine.
Idle before riding
Extremely cold temperatures can seriously damage your machine, so always run the engine at high rpms to warm up your equipment in cold weather. What you need to consider in the cold season, for example, when it comes time to clear snow using a shovel blade for a walk-behind tractor.
Cooling system maintenance
Regardless of the season, people tend to ignore the engine cooling system. For motoblocks with water cooling in the winter period, you should not use water, for this it is advisable to fill in antifreeze or antifreeze. But, many owners neglect this rule and fill in ordinary water. Our experts recommend taking distilled water so that there is no scale in the radiator combs. In turn, the liquid cooling system can be of a radiator type or with an evaporator (on older models). With the evaporator, you need to pour hot water into the radiator, and where is the radiator with the impeller. antifreeze can be poured there, but very high quality, otherwise it will corrode all rubber gaskets.
Motoblocks, where an air system is provided, are easier to start at subzero temperatures. they do not need freezing antifreeze and constant checking of the radiator. However, such an engine not only heats up faster, but also cools down, which is not very convenient when operating a walk-behind tractor in winter and does not allow for long breaks in work.
If necessary, warm up the engine and walk-behind tractor
Diesel fuel can thicken and turn into a paraffinized gel, it is difficult to inject it into the cylinder, so the engine needs to be heated at least a little. It is very important to give a cold diesel engine time to warm up. You should always allow your equipment to warm up for at least five minutes before using it. this will allow the oil to warm up. This rule also applies if the walk-behind tractor was in a garage or other unheated room. If possible, store the diesel engine or walk-behind tractor in a warm place where it will not be exposed to elements such as sleet. Leaving the engine indoors, where the temperature is even a few degrees higher, will speed up its warm-up.
How to start a diesel walk-behind tractor in winter?
Compact diesel motoblocks are designed for reliable starting and operation in winter. However, operation in cold weather requires special care, and preparation of the power plant for cold weather should not be neglected. For those planning to work during the winter months, it is important to learn how to start a cold diesel engine. This is important to keep your engine running for the coming seasons. However, for many, this can be difficult. We are often asked how to start a diesel walk-behind tractor in winter? Consider this issue in this article.
The diesel engine has a different design, it does not have spark plugs and the principle of compression ignition. Therefore, it reacts poorly to temperature changes, it is especially difficult to start it up in winter. And there are several reasons for this:
- Thickened engine oil;
- Incorrectly selected fuel or its poor quality;
- Low compression in cylinders;
- Fuel freezes in fuel lines;
- Low battery power;
- Damaged high pressure fuel pump and injectors.
There are several things you can do to prevent problems with starting your diesel walk-behind tractor in low temperatures. Cold weather itself is not particularly problematic as long as basic care and preventive maintenance is carried out throughout the year.
Since the walk-behind tractor is a multifunctional unit, many people prefer to use it all year round. In the cold season, it can serve as a snow blower, less often as a vehicle. In order for the end result to start the walk-behind tractor without problems, it is necessary to carry out several manipulations. After all, an incorrect engine start significantly reduces the working life of important mechanisms. When preparing a walk-behind tractor for winter, it is imperative to drain the water from the radiator, because water tends to expand when freezing, which leads to a rupture of the radiator.
A very important role is played by the place where you store your walk-behind tractor or the engine from it. It is certainly better if the equipment is in the garage and is not directly affected by frost, snow and rain. If this is not possible, the walk-behind tractor can be insulated with improvised means. a blanket, blanket or other dense fabric. Some manufacturers have foreseen this moment and produce branded covers. You can choose at your discretion. It is especially important to provide insulation in severe frost conditions, up to 20 ⁰C. If the temperature does not drop below 5-10 ⁰C, then this step can be skipped.
We start a diesel walk-behind tractor
Starting a diesel walk-behind tractor in winter is carried out in the same sequence as at any other time of the year. We described this in this article or you can watch this process in detail in the video.
The first step is to bleed air from the fuel hoses. To do this, open the tap, after which the connection for the diesel fuel supply is unscrewed, preferably near the nozzle and wait for the fuel to drip from the hose. Then move the lever of the air filter to the “open” position, the throttle handle is moved to the middle position. It is necessary to squeeze the lever 3-4 times and shake the decompressor several times and clamp it in the lower state. After performing these manipulations, you need to crank the engine crankshaft. When all the above steps are completed, the walk-behind tractor will be started, and after a short warm-up, you can start working.
Motoblock in winter
A modern walk-behind tractor is a productive and functional device capable of performing a wide variety of work on a personal plot. However, in most cases, this device is developed with an eye to use in the summer. At the same time, no one forbids operating it in the cold season, but at the same time it is necessary to take additional measures to ensure normal working conditions, as well as carefully monitor the conditions of use and the condition of the device.
Even if you do not plan to use your favorite walk-behind tractor or any other model, preparation for winter still requires certain procedures.
Most of the models presented are air-cooled, which greatly simplifies the maintenance of the unit in winter. There is no need to add antifreeze or keep the radiator intact. However, there are also disadvantages. Just as the engine heats up faster with air cooling in summer, it also cools faster in winter when it stops working.
In order to ensure normal operating conditions of the engine in winter, it is sometimes necessary to insulate it. Of course, if the air temperature is kept within acceptable limits, then you can do without it, but if severe frosts come, then without such insulation, the unit will not work normally.
You may be able to find special covers for your unit on sale, but this is unlikely. Most likely, you will have to make do with improvised materials and ingenuity. When insulating the engine, it is very important not to damage various components, as well as to protect the structure from getting insulating material into the clutch pulley and other moving elements.
The problem of starting a cold engine deserves special mention. On snow blowers and other units designed for winter use, various mechanisms and systems are used to facilitate this task, but we are talking about something else. Motoblocks favorite, like all the others, are designed primarily for summer use.
If you store your device in an unheated room, then a simple and accessible solution for everyone will suit you. warm up the engine by pouring hot water on it. A few liters will be enough to warm up your unit to a level that allows it to start.
Also, with frequent use of the walk-behind tractor in winter, it is worth worrying about the oil in the gearbox. You can use synthetic varieties that better than mineral ones retain their properties when the temperature changes. Or pour in more liquid oil for the winter period, since in the cold it will thicken.
Completely different procedures need to be performed if you plan to mothball your one-cylinder assistant until spring. In this case, it makes no sense to wrap up the engine and take care of warming up.
It is better to store the walk-behind tractor in winter in a dry and ventilated area, there is no need for heating. It is necessary to drain the gasoline from the tank and let the unit run until all fuel from the carburetor is completely depleted. Putting the walk-behind tractor for the winter, it will not be superfluous to check the oil level in the engine and gearbox, top up if necessary, and even better replace it with a fresh one.
Also, some owners recommend unscrewing the candle and pouring some oil into the cylinder. just a couple of teaspoons. Then manually rotate the crankshaft a couple of turns.
Well, it will not be superfluous to thoroughly wash the walk-behind tractor before conservation, so that there is no dirt and dust on it. You can also wipe all metal parts, in particular cutters, with an oily rag to prevent corrosion.

Why do breakdowns occur?
Motoblocks Bison are of high quality and endurance, but unpleasant moments do happen. If you are faced with a problem, you first need to find out why the Zubr diesel walk-behind tractor does not start. Then you need to immediately fix the problem or replace the failed part.
So, diesel motoblocks are somewhat different from gasoline ones. Consequently, the causes of breakdowns will also be different. Before work, you must each time check the serviceability and the presence of each part, the reliability of the fastening of mechanisms. Storage of equipment in the winter also plays an important role. If you leave the walk-behind tractor in a cold and damp room, you will encounter problems such as:
- clogging of carburetor jets;
- contacts will begin to oxidize;
- watering of fuel and oil;
- the insulating layer of the wires will be broken, and much more.
Always check the oil level and use only high quality oil. The piston system can be severely damaged if not properly lubricated. Old oil can disrupt the operation of the engine, and due to an insufficient amount of equipment, it will be difficult to start.
Motoblock Bison does not start. causes and solutions
Motoblocks today are the most demanded and useful technique for gardeners and gardeners. Thanks to her, you can greatly facilitate your work and process much larger areas without the risk of harming your health.
Like any technique, walk-behind tractors sometimes fail. However, do not despair. You can find and fix the breakdown yourself, and our article will help you in this matter.
Repair of units and mechanisms
It is worth noting that the first launch of a diesel walk-behind tractor is quite problematic. You need to bleed air from the fuel supply system. If the difficulties in launching still arose even after all the manipulations, then it is necessary to repair components and mechanisms. At the same time, you can correct minor defects yourself with only a small number of tools.
There are such malfunctions:
- Blockage in the diesel fuel supply system;
- Breakage in the carburetor;
- Blockage in the hole in the tank lid;
- The air filter is clogged, so the air does not pass through.
You also need to unscrew the candle. If it is wet, then you need to drain the fuel and dry everything well. Important: do not wipe the parts, they must dry naturally.
If the spark plug is dry, the reason may be that the fuel does not enter the combustion chamber. You need to disassemble it, clean every part, dry it, replace the fuel and put it back together.
The fault can also be in the ignition system. The reasons may lie in the magneto, spark plug, high-voltage wire or cap. You need to inspect every detail, as moisture and dirt can cause damage. After that, clean everything and collect.
Also check the condition of the piston system, exhaust and intake valves, muffler.
Each owner of walk-behind tractors, including the Zubr walk-behind tractor, should remember that timely detection of a breakdown and its correction is the key to the long service life of your equipment.

Motoblock does not start in frost
In severe frosts, situations sometimes arise when the car will not start. This often happens due to a dead battery, but there may be another reason. For example, this can be due to poor connection of the terminals with the battery, according to PRIMPRESS.
Open the hood of the car and use wrenches to tighten both battery terminals to the limit. If the car still won’t start after doing this, the problem is most likely in the battery.
If you are not in a hurry, then try to warm up the battery. To do this, place it in a warm room. This can take anywhere from 30 minutes to 3 hours. Do not try to speed up the process with any heat source. This is hazardous to both health and the battery itself. Alternatively, you can recharge the battery from the charger.
But there is a way to start a frozen car without removing the battery. If the battery is slightly discharged, then turn on the headlights for 15-20 seconds, and then turn the key in the starter. If it was not possible to start the car the first time, you can do such manipulations two more times.
You can also try recharging the battery from another car, if possible. To do this, connect the positive (red) terminals of the car, and connect the negative (black) terminal of the charged car to ground (the metal part of the car motor). It is not worth connecting the negative terminals of the car.
A charged battery should run for about 20 minutes at two thousand revolutions. After that, you can already try to start the car. It is desirable that the machines work together for another 5-10 minutes. Disconnect the wires in reverse order. Before starting the movement, it is recommended to idle a little.
If all else fails, try starting the car from the pusher. At the same time, someone must always stay behind the wheel in the cabin, since it is necessary to turn the ignition key, keep the clutch pressed and put the gear lever on the second or third speed. Then you need to smoothly release the clutch. When the car starts, you need it to warm up for at least 10 minutes. But this method can only be used by owners of cars with a manual transmission.
But, of course, it is better if there is a car service nearby, the car will be started with the help of portable starting and charging devices.
Note that the car may also not start in frost if the spark plugs are flooded, the starter is faulty, the ignition system is out of alignment, and the fuel supply is disrupted. Such situations can also arise due to low-quality gasoline, too thick engine oil.
To avoid such problems, you need to take care of this in advance. For example, monitor the level and density of the electrolyte and check the spark plugs, the tension of the generator and its charging, change the washer, antifreeze and, if necessary, oil.
Fuel system repair
A breakdown of the fuel system can be asserted if the engine:
- does not start;
- stalls under load;
- does not function stably at idle.
To eliminate the malfunction, first check the condition of all filters, including air and oil. If they are slightly clogged, blow with compressed air or flush; if they have strong contamination, they are replaced with new ones. Then the carburetor is disassembled, the parts are washed with a special cleaner, the fuel mixture supply valve, the tank and the piston system are cleaned with gasoline. After drying, carefully reassemble.
After the engine is completely assembled, the crankshaft is manually rotated. it is important that the piston moves freely and the valves work flawlessly. Then they pour in fresh lubricant, start the engine and leave it to work at idle. Be sure to check the flow of fuel into the cylinder. Perhaps, after such a repair, the cause of the malfunction will be eliminated, and the walk-behind tractor will begin to function without interruption.
DIY motoblock repair
Unfortunately, any equipment sometimes fails, so its owner needs to be able to troubleshoot on his own. Of course, if the car is under warranty, it is better to take it to a service center, where specialists will carry out warranty repairs for free.
Often damage to the cultivator, walk-behind tractor occurs due to improper operation: poor fuel is poured, heavy loads are allowed, or the loss of lubricating fluid is not replenished in time. Then the car starts to stall, “bury itself”, it is bad to gain momentum (especially if there is an electric motor on it), or even stops starting altogether. But, knowing the device of the unit and the principle of operation of its mechanisms, you can yourself identify the cause of the damage and carry out high-quality repair.
Preparing the walk-behind tractor for start-up
It is necessary to study the instructions drawn up by the manufacturer in order to find out what operating cycle the engine has: four-stroke (like Forte, Centaur, Lifan, Bison) or two-stroke. This is important to know, since for models with a two-stroke engine (like the Mole cultivator), a special combustible mixture is needed, consisting in a certain proportion of gasoline and oil. Due to the mismatch of the fuel, the equipment will stall, and the spark plugs and the fuel line may also suffer, which is fraught with the failure of the fuel pump. and this is already a direct path to expensive repairs at the service station. You can determine whether the fuel is suitable for motor vehicles by smoke. If the quality of the gasoline is poor, it will have a white color, as is the case with a strong tilt of the car. If you have bad gasoline, replace it to prevent damage.
Fuel quality is also important for a diesel walk-behind tractor. It does not start in winter or does, but soon stalls if summer diesel is poured into its engine. At low temperatures, it begins to thicken and clog the fuel line. In such cases, the risk of breakage increases. Choose the right fuel in cold weather.
The start-up of motor vehicles both in summer and in winter should be carried out in a certain sequence. For example, to start a Krot brand motor cultivator, the following procedure is carried out:
- open the gas tap;
- put the choke lever in the “Choke” position;
- turn off the ignition and turn the engine several times with a manual start-up starter;
- restart the engine and move the lever to the “Run” position.
Situations often arise when the power unit starts easily, but after a few seconds it stalls. In this case, it is necessary to check the permeability of the sump, perhaps the reason is that the tap is clogged. then it is cleaned with gasoline.
Starting a motorcycle with a diesel engine (such as Bison, Cascade, Centaur, Neva) will be somewhat more difficult than Mole. The diesel engine starts up with “airing” the fuel line, that is, with the release of it from air accumulations. For this:
- open the fuel supply valve;
- untwist the connections of the fuel outlet channel until the fuel appears;
- tighten the connections and blow through the nozzles.
Starting a cultivator after winter or a long downtime also has its own nuances. In order to bring the machine into working condition, the following manipulations are performed:
- open the gas tap;
- check if the power is on;
- check for lubrication;
- give gas, up to about half.
Какой мотоблок лучше? 8 или 9? Which walk-behind tractor is better? 8 or 9?
And, of course, before starting motor vehicles, be it Centaur, Cascade, Neva, Patriot or Bison, they check all connections, including transmission units, clutch, starting mechanisms and, if necessary, adjust them.
Ignition system repair
The breakdown of devices for ignition of fuel assemblies can be judged by the signs when the engine:
- starts, but stalls at idle;
- does not start even with good fuel supply;
- works at idle, but with some interruptions.
To find out the reason, first check the condition of the candles and, if there is damage to the insulator, replace them. Next, the electrodes are inspected and, if necessary, the gap between them is adjusted. They check the condition of the high-voltage wires for oxidation of the tips and insulation breakdowns. the damaged wires must be replaced with new ones. Without such a repair, the spark may completely disappear or it will go through the insulation, punching onto the engine housing, and will not be able to ensure the ignition of the fuel assembly.
If at this stage a defect with a spark is not found, then perhaps the reason that the equipment does not start or stalls lies in the generator or coil (for models such as the Neva, Cascade, it serves to form a spark). To check the generator, a measuring device is connected to its terminals. The motor-block starter pulley is scrolled and the readings of the device are recorded. they should be within 12-16 watts. If the indicators are normal, then the reason is contained in the ignition coil, and after replacing it, you can put a load on the engine. Most likely, after such a repair, its performance will resume completely.
The walk-behind tractor does not start: reasons for how to properly repair it
Owners of walk-behind tractors, cultivators, motorized towing vehicles and other mini-equipment sooner or later face a typical problem. their workhorse will not start or start, but stalls when the air damper is opened, starts to “shoot”, gas or “sneeze”. To eliminate the annoying interference, you need to find out the reason for which it occurs, and then carry out proper repairs. This problem occurs on Chinese, Japanese, Korean-made equipment.
Reasons why the walk-behind tractor does not start, and how to fix them
There are several reasons why motor vehicles do not start when starting. These include:
- damage to the carburetor (in motoblocks with a gasoline engine);
- malfunction of ignition / glow devices;
- low lubrication level.
When strange changes appear in the cultivator, and its operation becomes unstable, the carburetor is first checked. In this important unit, a fuel-air mixture (FA) is formed and dosing for feeding into the cylinders of an internal combustion engine (ICE). And if the jets become clogged, the fuel system becomes obstructed, as a result of which the carburetor loses its ability to start the engine. To eliminate the malfunction, the fuel line is repaired: the carburetor is partially disassembled, the pump is washed and the nozzles are blown through the fuel nozzle.
Sometimes the reason that the walk-behind tractor does not start lies in a malfunction of the spark plugs (the spark has disappeared), which play an important role in starting a carburetor ICE, or glow plugs that ensure the start of a diesel engine. If the fuse devices become wet, which happens due to the throwing of their fuel assemblies, then a spark begins to disappear on them. In the absence of sparking, ignition of the air-fuel mixture does not occur, and therefore the engine cannot be started. This problem can be solved in different ways:
- make minor repairs and replace the inoperative candle with a new one;
- “Burn through” flooded candles and use fire to clean them of traces of gasoline.
Motorized equipment does not start due to the fact that damage to the glow plugs occurs. In a diesel engine, fuel is ignited by contact with hot air, which is heated in the cylinder by compression by a piston. This happens without any problems when the diesel engine has already warmed up and the operating temperature in it is maintained by the heated cylinder walls. But in cold weather, and especially in winter, the engine is warmed up using incandescent devices and, if they are out of order, it will not be possible to start the walk-behind tractor.
If, when inspecting a carburetor engine or diesel engine, no defective spark plugs were found, but problems remained, and even accompanied by pops into the muffler, you should check the operability of all devices responsible for the flammability of the fuel. A malfunction in them can also be the reason that the walk-behind tractor does not start. Diagnostics is best done in a service center, where professionals will find the cause of the damage and competently carry out repairs.
Motorcycle equipment will not start even with an insufficient level of lubricant in the engine. Some models are equipped with special control sensors, which, in the event of a lack of lubrication, do not allow the engine to start. Particular attention should be paid to those machine variants that do not have such sensors. Sooner or later, the level of the lubricant mixture will reach a critical value and, if it is not replenished to the norm, this will soon lead to wear of parts and, as a result, to overhaul of the engine.
The following factors indicate a transmission malfunction:
- the working shaft is motionless, and the output shaft rotates;
- engine speed does not match the speed of the working shaft;
- the engine seems to “choke” from the load.
If at least one of the above reasons manifests itself, they immediately check for the presence of grease in the gearbox. The lubricant in it must be normal, as the lubricant prevents “dry” friction of moving parts and prevents them from overheating.
Then the gearbox is disassembled, the gears are inspected, the chain tension is checked. Whole parts are washed in kerosene, and damaged parts are replaced with new ones. After that, they assemble the structure and make sure that the gears are not skewed.
Before installing the assembled gearbox on the walk-behind tractor, the shafts are scrolled to make sure that they rotate evenly and without the slightest grinding. The gearbox is filled with fresh lubricant and the motor-cultivator is started. In the absence of a leak under the body, perform simple operations with a rotary tiller or a mounted loader and check the functionality of the walk-behind tractor. If its working capacity is restored, then all efforts were not in vain, and the repair and maintenance were carried out correctly.
Why the walk-behind tractor does not start?
Malfunctions with this problem can be very diverse and refer to different systems of the walk-behind tractor. First of all, you need to check the availability of all the necessary spare parts and components, especially if the walk-behind tractor is new, or vice versa. it has not been used for a long time. Before starting, carefully check all fasteners, connections and cables, their course. Make sure that there is oil in the crankcase and that there is sufficient fuel in the tank. Do not start the walk-behind tractor if the movement of the cables is difficult. this may indicate that the threads of the harnesses are twisted.
After the winter rest, the most common reasons for the failure to start the walk-behind tractor are oxidized contacts, broken insulation of the wiring, deterioration of the quality of fuel and oil during downtime.
Also, the common reasons that the walk-behind tractor does not start well include:
- breakdown and / or clogging of the carburetor and its components;
- malfunctions in the ignition system (the most common breakdown);
- low level of lubrication or its complete absence in the gearbox;
- cylinder problems.
The walk-behind tractor does not start: the most common reasons, breakdowns
There is no spark on the walk-behind tractor
This malfunction is directly related to the breakdown of the ignition system. Failures in the ignition system include malfunctions of the magneto, generator, wiring, cap and spark plugs. If the spark is missing or it is weak, the reason is only in the cap and the candles. First of all, remove the candle, assess its condition. If necessary, wipe off the carbon deposits from it and “fry” it over the fire (if there is no way to instantly replace it with a new one).
Replace the candle and try to re-start the walk-behind tractor. If there is still no spark, check the contact of the cap with the center electrode of the spark plug. The gap between the cap and the electrode is checked with a special probe and should be 0.8 mm.
A few words about how to avoid such situations. First of all, always strictly follow the recommendations specified in the operating instructions. If you stick to them, your walk-behind tractor will last much longer.
Also, in order to avoid problems with starting the walk-behind tractor, it is important to know what the engine cycle is for this model (which is also indicated in the instructions). For example, Neva motoblocks (MB-1 and MB-2, which are most often equipped with a Subaru engine), Zubr, Salyut, Agro, Kaskad are equipped with a four-stroke engine. And the Mole motoblocks have a two-stroke engine. The value of this information for owners is that it indicates how to properly refuel the equipment. For models with a 2-stroke engine, a special fuel mixture must be prepared, for which gasoline and oil are mixed in a certain proportion. For motoblocks with a 4-stroke engine, oil and gasoline are poured separately. But do not forget to also monitor their quality.!
Also, you should always remember about the correct order of starting your walk-behind tractor. For example, for a Krot walk-behind tractor or any other unit with a gasoline engine, the start-up is carried out in the following sequence:
- Open the gas supply valve.
- Set the fuel choke lever in the “Choke” mode.
- With the ignition off, the engine is worked through by the kick-starter several times.
- Start the walk-behind tractor and switch the fuel suction lever to the “Run” position.
With diesel engines of Neva, Zubr, Salyut, Kaskad or Agro motoblocks, the situation is a little more complicated. First you need to bleed air from the fuel system. To do this, open the fuel supply valve, unscrew the fuel hose connections until fuel appears, tighten the connections and blow out the injectors. If, after the performed manipulations, the walk-behind tractor does not start or does not start, but thick white smoke comes from the muffler, you need to urgently change the oil.
After a long downtime, the diesel engine should be started according to the following algorithm:
- Open the petrol tap.
- Check for grease.
- Switch on ignition.
- Twist the throttle handle slightly, no more than halfway.
We also suggest that you familiarize yourself with the video on how to properly start the walk-behind tractor:
Preparing the walk-behind tractor for winter
Proper preparation of equipment before the winter period plays a huge role in extending the life of the walk-behind tractor available on the farm. Many novice farmers make big mistakes at the same time, leaving the unit to winter in unsuitable conditions, or trying to bring it into subzero temperatures without preliminary preparation. As a result, the main mechanisms of equipment lend themselves to increased wear, and inevitably fail at the most inopportune moment.
How to start a walk-behind tractor in winter. tips for beginners
The advantages of a modern walk-behind tractor are its versatility and high performance. Subject to the availability of appropriate attachments, the unit available on the farm can be actively used in the winter. for clearing a large amount of snow and solving other household tasks.
At the same time, improper operation of the walk-behind tractor in winter, and especially its incorrect start-up, significantly reduces the working life of the main mechanisms of the unit. What to do. to prevent typical mistakes when starting a “cold” walk-behind tractor?
First of all, you will need to understand the type of cooling system provided for in its design. Units equipped with an air system are easier to store and start up in the winter. they do not need fast freezing antifreeze and constant radiator checks. At the same time, the air cooling system also has its drawback. the engine heats up faster with it, which means it cools down faster, which will not allow taking long breaks when working in winter.
Many walk-behind tractors need preliminary insulation of their engines for winter operation. For this purpose, both branded covers and various improvised means. blankets, blankets and other fabric products can be used. It is especially important to provide high-quality insulation in severe frost conditions, up to 20 ⁰C. If the temperature does not drop below 5-10 ⁰C, then this step can be skipped.
An important role is also played by the place in which the walk-behind tractor is stored. If the unit is planned to be actively used in winter, then it is best to choose a heated room for this. a garage or other utility building.
With intensive use of the walk-behind tractor in winter, it is extremely important to take care of the oil in the gearbox. Synthetic oils are better for use in winter, since they retain their most important properties longer than mineral oils at subzero temperatures. In any case, it is best to use thinner oils that do not thicken so quickly in the cold.
Observing all these rules, the owner of the walk-behind tractor can easily start his unit. The start of the agricultural machine in winter is carried out in the same sequence as at any other time of the year. The only difference is to let the walk-behind tractor idle for at least 15 minutes. during this time, its engine will warm up and be completely ready for work. details about starting a walk-behind tractor in winter can be found in the video.
Preparing the walk-behind tractor for winter. what you should take care of?
Correct preservation of the walk-behind tractor for the winter is an important topic that allows, if not prolong, then at least preserve the working life of the unit used on the farm. The preparation of an agricultural machine itself is not a complicated procedure. It is enough to study a number of rules and tips that will help keep the walk-behind tractor and start it up without problems after wintering.
When sending the unit for winter storage, you will need:
- completely replace the oils present in the motor and gearbox of the unit. To do this, you will need to fill in a new lubricant in the appropriate tanks for the winter, or, in extreme cases, filter out the old one, making sure that there is no sediment in it. In any case, with the onset of spring, the oils will need to be replaced;
- wash all filters available in the construction of the walk-behind tractor. If the unit is equipped with filters placed in an oil bath, then they will need to be filled with fresh engine oil;
- many experienced farmers recommend unscrewing the spark plugs of the walk-behind tractor before winter storage, then pour no more than 20 ml of engine oil into the working cylinder, and manually rotate the crankshaft of the unit, performing literally a few revolutions;
- The walk-behind tractor for the winter must be washed from dirt, without missing parts located in hard-to-reach places. After washing, a thick layer of oil will need to be applied to the body and parts of the unit, which will help eliminate the formation of corrosion;
- if possible, instead of oil, a special polish with a protective function can be applied to the parts of the walk-behind tractor. it forms a strong film on the metal surface, which will prevent the metal from rotting in winter. In this case, it is very important to apply the product to a clean surface, since otherwise it will not protect the metal parts of the walk-behind tractor;
- all candle caps and electrical connectors of the unit for the winter must be lubricated with silicone grease in the form of a spray. it will effectively protect their effects from various environmental factors;
- if an electric starter is provided in the design of the walk-behind tractor, then during winter storage it is best to remove the battery from the unit and move it to a dry and warm room. During storage, the battery will need to be fully charged several times;
- in order to prevent the rings from falling into the cylinders in winter, you will need to open the fuel supply valve of the walk-behind tractor several times a month and pull the starter handle 3-4 times.
By adhering to these simple rules, the farmer will provide optimal conditions for storing the walk-behind tractor in winter. With the onset of spring, the unit can be taken out of the room, the oils changed, and the unit can be operated.
Do I need to drain gasoline from the walk-behind tractor for the winter?
There is a lot of controversy about whether it is necessary to drain gasoline during the winter storage of the walk-behind tractor. Some farmers advise keeping the unit without fuel, others are of the completely opposite opinion.
In fact, it all depends on the type of fuel consumed. If the farm uses a diesel walk-behind tractor, then not everyone will be able to store it in very severe frosts with fuel in the tank. First of all, this is due to the property of a diesel engine to freeze already at 10 ⁰C. To avoid this, various additives can be poured into the diesel fuel tank, which will prevent the fuel from freezing. At the same time, even the most effective additives are not able to maintain the liquid state of a diesel engine at temperatures from 25 ⁰C and below. Therefore, if the winter in the region is very cold, then it is best to drain all the fuel from the diesel walk-behind tractor before storing.
Things are quite different with gasoline motoblocks. Most experts are inclined to believe that such units are best stored with a full tank of fuel. This will help prevent corrosion on the inside of the fuel tank walls. In this case, it is extremely important to completely fill the tank, otherwise rust can form on the walls in the empty part of the tank.
Why Diesel Engine Won’t Start. Let’s try to figure it out
The diesel engine is widely used in the modern automotive industry. Its main competitor, as everyone knows, is the gasoline internal combustion scheme.
In general, the main difference between a gasoline engine and a “diesel” is that the cylinders of the first receive a ready-to-use fuel-air composition, while in the second these elements are supplied separately. This fuel delivery scheme helps diesel systems to significantly gain power while using less fuel.
But, as usual, there is no good without a silver lining. Diesel engines are considered by many technical experts to be much more capricious than their gasoline competitors. And, unfortunately, every owner of such a “gentle” engine risks in the morning instead of the usual juicy sound of an awakened engine to hear only an indistinct rattle or a gloomy silence after turning the key in the ignition lock. Why did this happen? But now let’s try to figure it out.
There are several typical troubles that happen with diesel engines with enviable regularity. Here are three of them:
Why Won’t My Tractor Start in the Cold? – 5 Tips & Tricks to starting your tractor this winter
The starter motor is working properly, whitish smoke appears, but the engine will not start
This situation indicates that the fuel in the cylinders does not ignite or only partially burns. But at the same time, you can be sure that the fuel system is working properly. Most often this happens due to malfunctions of the glow plugs (they can either simply burn out or stop receiving a sufficient voltage level). It is also worth paying attention to the correct setting of the angle of the start of diesel injection, because sometimes, for various reasons, the injection pump belt can jump and knock down the system setting. Well, the worst diagnosis that can be made in this case is a low compression level in the system. And this, unfortunately, is fraught with “capital”.
Starter motor operates normally, smoke is emitted, but the engine “does not seize”
If there is no smoke, then there is no fuel in the combustion chamber either. The most harmless reason that can only be in this case is the erroneous operation of the anti-theft system. But in this case, you should not wave your hand carelessly. after all, sometimes after such operations, the injection pump may even need to be repaired. If this option with the anti-theft system disappears immediately, then you need to pay attention to the following sections of the car’s power plant: the fuel filter (it can be littered), the fuel line (and specifically, its weak tightness), the fuel itself (and the formation of paraffin in it). Also, if the above-mentioned signs appear, it may be necessary to repair the injectors.
An uneven starter is heard. The ignition system works in jerks and the diesel engine “does not seize” and does not start
Most likely, the forecast is not comforting. the timing belt is torn. It is strictly forbidden to start the car in this state. After all, the more fruitless attempts to “revive” the motor, the more likely it is to damage the internal structure of the power apparatus itself.
Starter does not turn
If the starter does not turn, you should check the battery charge and the performance of the starter.
What could have caused such an unexpected deterioration in the work of the diesel “fiery heart”?
Most often, the troubles described above arise from unprofessional service and neglect of cars. The most important rule, which is strongly recommended for all owners of used diesel cars in the CIS, is to change the engine oil after 7000-8000 km.
At the same time, technical experts recommend not looking too closely at the manufacturer’s recommendations. After all, they do not take into account the peculiarities of our fuel, in which an increased sulfur level has already been ambiguously noted, which, without options, leads to earlier oxidation of lubricants. This chemical reaction causes the oil to lose most of its beneficial and protective properties.
It is also worth saying once again that it is best to repair a car (and especially its fuel system!) In specialized services. In such as “Sloboda Diesel Service”. After all, this is one of the few service stations that REALLY specializes in the repair of diesel cars and knows literally everything about them.
What to do if your Tiguan won’t start in cold weather
Many experienced motorists have at least once faced the problem of starting the engine in severe frost. In essence, such an incident is not particularly surprising, because most cars operate stably only in the temperature range from plus 40 to minus 20 degrees Celsius. And what about Russia and other CIS countries? Frost often exceeds the level of minus 25 and minus 30. Most often, the owners of one of the most popular crossovers, the Volkswagen Tiguan, suffer from the problem of starting the engine in winter. And the point is not that this model is made of poor quality, but in some of its features. In more detail about what to do if the Tiguan does not start in frost, we will talk in today’s article.
The main cause of the problem is the starter
Volkswagen Tiguan is a quality car, so the problem with starting its engine in frost is very surprising. With the appearance of such incidents, many owners of this model began to complain to the head office of the auto concern and asked for advice on how to solve them. After some time, the manufacturer still found the very “root of evil” that made life difficult for motorists. The starter is to blame.
The fact is that the Tiguan starter is a standard unit for modern cars. Structurally, it consists of the same pins, pads, housing and holes in it for ventilation. During operation in places with high humidity and low temperatures, ice forms on the contact pin of the starter, which is responsible for cranking the engine shaft. The outcome of this phenomenon is that the starter either does not turn the engine at all, or does it extremely weakly, and as a result, the car does not start in frost. This incident can be attributed to chronic “sores” Tiguan only for the reason that the starter of the model is located behind the radiator, which is why it is additionally blown with cold air.
The carmaker immediately responded to the problem and advised Tiguan owners on how to solve it. As the manufacturer recommends, in order to start the crossover engine in cold weather, you must do the following:
- First of all, check the power supply system of the motor and the mains. If everything is normal with them, then the culprit of the problem is the starter.
- Now sit in the car and start cranking the engine with the starter literally for 2-3 seconds, doing this about 6-8 times. After completing the procedure, it is advisable to wait 30-40 seconds.
- Further, it remains only to start the car, since the starter pin has heated up and all the ice has melted.
After solving a one-time problem with a starter, it will be easiest to avoid it. For this, one thing is enough. do not park the car in frosty places where high humidity and positive temperatures persist for a long period. Otherwise, going out into the cold will “break” the starter and the problem will repeat again.
Other reasons for the inability to start the motor
Of course, about 70% of cases when Tiguan does not start in frost are associated with the problem described earlier. What happens in the other 30% of situations? Let’s figure it out.
In fact, there are not so few reasons for the impossibility of starting the Tiguan engine in winter. At their core, they can be caused by two main factors:
- the first. there is nothing to ignite, that is, the fuel either does not enter, or does not enter the engine well;
- the second. there is nothing to ignite, that is, the fuel reaches, but its ignition system fails.
In order to deal with all sorts of causes of the problem, it is worth considering both options. So why the Volkswagen Tiguan does not start in cold weather due to problems with the fuel system:
- There is fuel, but it is of poor quality. Solution: drain bad gasoline and continue refueling at proven gas stations.
- Clogged fuel, air filter or injector. Solution: replace or clean damaged parts.
- The fuel does not reach the engine, otherwise there is no pressure in the fuel system. Solution: check and, if necessary, replace the fuel pump or its regulator.
- Moisture has frozen in the fuel filter (relevant in frost only for diesel engines). Solution: put the car or the filter itself in a warm place and wait a few hours.
- Other problems associated with the inability to work of some car systems in frost (broken fuel wire, for example).
Well, now, let’s look at the reasons for the lack of starting the Volkswagen engine in cold weather due to problems with the ignition system:
- The battery is discharged. Solution: charge or, if the battery is faulty, install a new one.
- There were problems in the electronic ignition system: a wire was broken, the ignition coil was out of order, and the like. Solution: find the problem by calling an electrician and fix it.
- There is a problem with the spark plugs. Solution: unscrew, check, clean and, if necessary, replace.
In addition to the above reasons, the Tiguan engine may not start in frost because it itself has failed. In such a situation, it is advisable to deliver the car to a service station, where professionals check the compression, wear of engine components and will act on the basis of the information received.
In general, we can dwell on the considered reasons why the Tiguan does not start. This model does not have any other “sores”. We hope that the material presented earlier was useful to you. Good luck with the repairs and on the roads!
