How to reverse on a mole cultivator

Which elements of the machine may require the operator’s close attention?

And now let’s take a closer look at all those malfunctions that can affect the performance of the unit, no matter what model it belongs to.

Will not start

So, what to do if “Mole” Not start, what can be the reasons. The ignition fails, or is completely absent in the following cases:

  • No spark. This could mean that the spark plug is burned out. In this case it is necessary to unscrew the spark plug and simply replace it with a new working spark plug.
  • Spark plug is smoky. It will return to life a good cleaning (remove carbon deposits, wipe the contact), then the candle should be well washed in gasoline.
  • If the cultivator does not start, but the spark is there, then, most likely, the reason is in the lack of insulation. Again look at the plug, in this case it is wet or slightly damp. You don’t need to replace the entire spark plug, just the tip.
  • Poor quality fuel can be the reason of the lack of ignition of the cultivator. It is for this reason the spark gets wet, after which it will be necessary to change the tip.
  • Drainage of fuel from the spark plug is another reason for not starting the car. To rectify the situation it is necessary to drain the cylinder, pumping the motor with a manual starter.
  • The reason for the lack of ignition can also be a problem with the hoses that supply fuel. To restore the work of the power tiller it is necessary either to tighten the hoses well or, in case of rupture, replace them with new ones.
  • Poor insulation of the electrical system (high-voltage and low-voltage wires) can also be the reason that the unit does not start.
  • Pay attention to the air filter. If it is dirty, ignition problems are assured. It must either be cleaned or replaced. often the second option is chosen, thanks to the price and availability of this part in the store.
  • Failure of the magneto itself. This part cannot be repaired and must be replaced with a new one. How to check the magneto of a power tiller “The Mole”, To see if it’s faulty? Yes very simply. if all the reasons why the spark might be missing are ruled out, then the cause of the malfunction is in the magneto. Many craftsmen remake the working magneto, thereby increasing its resource.

Here’s how a Magneto ignition diagram for a power tiller might look like “The Mole”

  • Ignition can be absent if the flywheel plates jam the magneto cores.
  • Improperly set the gap between the electrodes will not allow the spark to jump.

Engine

The main reasons that the engine “Mole” does not start, are:

  • lack of fuel (or its low quality);
  • Ignition problems, discussed above;
  • appearance of decompression and, as a result, piston wear, deformation of the exhaust valve.

In the first case, just pour the required amount of fuel (mixture of gasoline and oil M-8B Autolom) and all the problems will be resolved. In the case of a violation of compression, you will have to completely disassemble the engine and replace the damaged parts, and that can be a piston, an o-ring.

Deformation of the exhaust valve becomes another cause of compression failure, leading first to the loss of power of the power tiller “Mole”, And then to the starting problems.

To restore the engine capacity you need to disassemble it completely. After assessing the condition of the piston we replace it if necessary. Replace piston rings, exhaust valve. Examine the engine head, in particular the timing mechanism, if there is fouling. clean it. In case of damage to structural elements. replace them with serviceable ones.

Engine choice

In the Soviet Union only domestic-made two-stroke single piston engines were used, not very powerful. Today you can find “The Mole” with imported four-stroke engine. But if in your arsenal is still the first model of cultivator, then modernize your “The mole” It is not difficult to change the engine

And there arises a new question: what engine is better to install on the machine? It is not difficult to answer it. those models that are installed in newer machines will do.

It is best to carry out the replacement of the domestic engine with an imported one:

Any of them will not only give a motocultivator a new life, but also significantly increase the power and resource of the unit.

Lifan engine installation on a rotary cultivator is an excellent solution “Mole”. Such a motor provides the car a long life, because in addition to reliability and efficiency, Lifan stands out for its unpretentiousness and will not require additional attention.

Adjustment of the carburetor is necessarily carried out after the first working season.

Adjusting the carburetor is one of the mandatory moments included in the “maintenance” unit. Thanks to the timely inspection and repair the service life of the cultivator will increase. Inspection and adjustment is also necessary if the engine roars heavily for no apparent reason.

Before proceeding to the adjustment, it is necessary to get acquainted with the structure of the carburetor of the cultivator “The Mole”:

So, to debug the fuel supply and to provide the necessary RPM, it is necessary to turn to two screws: number of revolutions (on fig. Check the carburettor and fuel quality (Figure 6) and the carburettor cap (Figure 7). ). Use the two screws to check the carburetor’s fuel supply “Mole” at idle speed. Act very carefully, you should first check the state of the ignition.

Important! Thoroughly clean the carburetor, sand it down where necessary, wash it, and change parts where necessary. Then the Mole will serve you for a very long time.

The owners of the unit are often interested in how to start the cultivator “Mole” after the winter. The cause of the lack of ignition is condensation in the carburetor, accumulated during idle time at shift temperatures. The solution to this problem is to completely disassemble the unit and then clean it. All sorts of additives found in low-quality fuel and dust that has seeped through the filter will also not contribute to the operation of the device.

And now let’s take a closer look at all those malfunctions that can affect the performance of the unit to whichever model it belongs to.

Won’t start

So, what to do if “Mole” doesn’t start, what are the possible reasons? Ignition is broken, or there is no ignition at all in the following cases:

  • No spark. This can mean that the spark plug is burned out. In this case, you need to unscrew it and simply replace it with a new working one.
  • The spark plug is burned out. A good cleaning will bring it back to life (remove the carbon deposits, clean the contacts), after that the spark plug should be well washed in gasoline.
  • If the cultivator does not start, but the spark is there, then, most likely, the reason is the lack of insulation. Again look at the spark plug, in this case it is wet or slightly damp. It is not necessary to change the entire spark plug, only the tip.
  • Poor quality fuel can be the reason for the lack of ignition of the cultivator. That is the reason why the spark plug gets wet and needs to be replaced.
  • Drip from the spark plug is another reason why the machine does not start. To correct the situation it is necessary to drain the cylinder by pumping the engine with the hand starter.
  • The reason for the lack of ignition may also be a problem with the hoses that supply fuel. To restore the work of the motocultivator it is necessary to either good tension the hoses, or, in case of rupture, replace them with new ones.
  • Insufficient insulation of electrical system (high-voltage and low-voltage wires) can also be the reason of the machine not starting.
  • Pay attention to the air filter. If it’s dirty, ignition problems are assured. It must either be cleaned or replaced. often they have resorted to the second variant, good, this spare part is accessible both by price and availability in a store.
  • Failure of the magneto itself. This part can not be repaired and must be replaced with a new one. How to check the magneto motocultivator “Mole” to make sure of its failure? It’s very simple. if all the reasons for the absence of spark are excluded, the magneto is the cause of malfunction. Many craftsmen modify the working magneto, thus increasing its resource.

Here’s how the ignition diagram may look Magneto for motocultivator “Mole”

  • Ignition can be absent if the flywheel plates jam the magneto cores.
  • Improperly set electrode gaps prevent the spark from flowing.

Engine

The main reasons that the Mole motor does not start are:

  • lack of fuel (or its low quality);
  • Ignition problems, discussed above;
  • appearance of decompression and, as a result, piston wear, deformation of the exhaust valve.

In the first case, simply pour the required amount of fuel (mixture of petrol and oil M-8V Autolom) and all the problems will be solved. In the case with violation of compression, you would need to disassemble the engine and replace the damaged parts, and that could be a piston, an o-ring.

Deformation of the exhaust valve is another cause of compression failure, which leads first to a loss of power of the Mole motocultivator, and then to starting problems.

To restore the engine operation it is necessary to perform a complete disassembly of the engine. After assessing the condition of the piston, if necessary replace it. Change of piston rings, exhaust valve. Examine the head of the engine, in particular the gas distribution mechanism, if there is fouling. clean it. In case of damage to structural elements. replace them with serviceable ones.

Choosing a motor

In the Soviet Union only domestically made two-stroke single-piston engines without much power were used. Today you can find a Mole with a four-stroke imported engine. But if you still have in your arsenal the first model of cultivator, then modernizing your “Mole” by replacing the motor is not difficult at all.

And there is a new question: what engine is better to install on the unit?? It is not difficult to answer. the models installed in newer cars will do.

The best thing to do is to replace the domestic engine with an imported one:

Any of these will not only give your motocultivator a new life, but will also significantly increase the power and service life of the unit.

A great solution would be to install the engine Lifan on the motocultivator “Mole”. Such a motor provides the machine a long life, because in addition to reliability and efficiency, Lifans stand out more and unpretentious and definitely will not require additional attention to themselves.

The carburetor adjustment is mandatory after the first operating season.

Adjusting the carburetor is one of the mandatory moments included in the section “maintenance” of the unit. Thanks to the timely inspection and repair service life of the cultivator will increase. In addition, inspection and adjustment is also necessary when the engine roars badly for no apparent reason.

Before proceeding to the adjustment, it is necessary to get acquainted with the device of the carburetor of the cultivator “Mole”:

So, to adjust the fuel supply and provide the necessary RPM, you need to turn to two screws: the RPM screw (in Fig. ) and fuel quality (fig. ). With the help of these two screws we make the adjustment of the fuel supply to the carburetor of motocultivator “Mole” at idle speed. Act very carefully, you should first check the state of the ignition.

Important! Thoroughly clean the carburetor, sand it where necessary, wash it and change parts where necessary. The main function of the gearbox is to transmit the engine torque to the shaft.

reverse, mole, cultivator

The domestic single-axle tractor is notable for its smart design. there is nothing superfluous in it. The cultivator can be equipped with various attachments, which allows using it for various purposes. The equipment is reliable and can withstand loads for a long time.

  • Frame consisting of two half-frames and bolted to the gearbox.
  • Tubular handle and bracket. for the placement of the attached implements.
  • Control levers. The handle is equipped with controls. you can switch the clutch and engine speed. Some models of the Mole are additionally equipped with a reversing switch.
  • Pneumatic wheels attached to gear output shafts.
  • Two-stroke single cylinder engine. The cooling system is air. The engine is attached to the frame; it is connected to the gearbox shaft by a V-belt transmission.
  • Single-axle tractor complete with cutters. two outer and two inner cutters. Coulter coulter is also included. Optional equipment with hoe, weeder, plow, pump, mower.
  • V-belt transmission connects the engine for the Mole motor and the gearbox. The latter has a chain drive and is bolted to the frame. A fuel tank is located above the engine and gearbox.
  • The mini-tractor has a special handle for shifting the clutch. the same as on mopeds. Clutch is in the off position, when engaged the belt is tensioned and the torque is transmitted without slipping.
  • On the output shafts of the gearbox are installed working cutters, which work the soil, or wheels. they are needed for transportation of goods and for plowing the soil with a plow. Cutter. rotor with special blades that, by rotating and moving forward, cut and crush the soil.

Tines, compared with the plough, more thoroughly loosen and mix the fertilizer. Can work effectively on virgin and heavy soils.

Tiller has built-in wheels for easy maneuvering. Before beginning work, they are dismounted or jacked up and secured in position. Tiller is run-in for 15 hours at partial load.

  • weight (empty tank). 51,5 kg;
  • working width. 40-60 cm
  • rotor diameter (taking into account the knives). 32 cm;
  • plunge cut depth. 25 cm;
  • dimensions (DxHW). 100-130×35-80×71-106 cm;
  • throughput. up to 200 square meters. m/h.

What kind of work is used for

The main task of the “Mole”. plowing the land, but the dacha owners adapt this unit for many works:

Depending on the model, cultivator’s functionality may vary, as well as the specifics of work performed by it. The main working body of this device is considered a cutter. Virgin lands are crushed solely with internal cutters, but for light soils the whole set can be used. Tillers can be equipped with up to six tools, but they cannot pull more than that because of the high risk of overheating the engine.

During weeding, it is obligatory to install K-shaped weeders, and the outer cutters are replaced by discs, which protect the plants. When hoeing root crops, instead of using tillers, it is equipped with wheels and, separately, with grousers. The coulter is replaced with a potato cultivator.

The great advantage of a cultivator is that it is possible to attach a mower to the front part of the machine. A pulley is placed on the output shaft and a V-belt transmission is used to connect the linkage to the engine.

When pumping water, the cultivator is equipped with a pump using the V-belt drive. If the blades are replaced by rubber-coated wheels and a cart is attached to the frame, the cultivator can be used to transport the harvested crops.

Modernization of a motocultivator KROT

In Russia Krot motocultivators of “Mole” type have been produced for a long time. The first model of the MK-1 “Krot” motocultivator was manufactured as a single-purpose machine for tilling the ground. By now the technical capabilities of motocultivators are significantly expanded and there is even a set of mini fodder machines developed to complement them. Outwardly, motocultivators resemble power tillers and their basic structural units are the same.

Description of the KROT power tiller

MK-1 “Mole” motocultivator:

operating device (rotor); 2. gearbox; 3. operating device knife; 4. gas tank; 5. engine “stop” button; 6. clutch control lever; 7. carburetor throttle control lever; 8. engine; 9. opener; 10. support; 11. frame; 12. transport wheel

MK-1 basic units (see pic. Fig.) are engine with built-in gearbox (described below), transmission, control system, operating elements, coulter, wheels.

Transmission provides the torque transmission from a single-stage engine reducer to the actuators, and consists of a V-belt transmission and a lower two-stage gearbox. V-belt drive also serves as a clutch. Work tools are installed on the output shaft of the reduction gear.

The throttle actuation system consists of two levers that are adjustable in length and width. The throttle lever of the carburettor is on the left-hand side and the clutch lever on the right-hand side. There is a stop button in the control system to stop the motor.

Actuators are designed as rotors, each with four specially shaped blades. 320 mm diameter milling drum assembled from two or four rotors. Working width of the bar is 330 mm in the first case and 580 mm in the second case. If two additional rotors are installed which the design of the walking tractor allows, the width of the cultivated area will be 830 mm. Tilling drum rotates at 85 rpm and cultivates the soil to a depth of up to 20 cm (depending on settings).

The power tiller moves forward by rotating the working elements. rotors that simultaneously perform the technological process.

The coulter is installed behind the tools and serves as a depth control for tillage. coulter height can be adjusted in steps.

The disc wheel pair with rubber rim has no drive and only serves to move the cultivator; during operation, the wheels are lifted upwards.

Productivity of MK-1 at milling the soil to a depth of 20 cm is 0.017 ha/h, and at cultivation to a depth of 10-12 cm. 0.05 ha/h, that is, its use on the most labor-intensive operations of treatment. than 5 times faster than manual operation. The MK-1 power tiller is supplied with auxiliary devices: wing blades with L-shaped knives with wedge-shaped blades; discs protecting against damage during rotary tillage; a hoe. Using these devices, you can complete the unit, for example, for combined processing of potato row spacing: share shares are installed instead of the working bodies of rotors, and protective discs on the shafts of share sections; spudger is installed instead of plough the back of the frame. When the machine is working, the share blades loosen the soil, trim weeds and simultaneously help move the tiller, and the perch on the loosened soil perches two adjacent seedbeds on one side each in one pass. Such unit processes 0.14 hectare/h, which is 18 times more productive than doing similar work manually.

Overall dimensions MK-1. 1300 X 800 X 810 mm, weight 50 kg, it can be easily placed in the trunk or on the roof of the car.

In general, for modifications of all tillers of “Mole” type besides the already mentioned for MK-1 working bodies are produced a small plough, mower, semi-trailer with a carrying capacity of 200 kg, water pump. A front attachment is designed to form a motorized cart when the attachment is connected to the power unit of a motorized cultivator. A sprayer, home sawmill and other devices are designed to be used with this power unit.

MK-2 and MK-3 models have 320 mm wheel diameter, 90 mm ground clearance, 285 or 600 mm wheel track, 1960X800X1170 mm dimensions. MK-2 has one forward gear for speed up to 7 km/h and weighs 50 kg. The MK-3 model has two forward gears, providing travel speeds of 4.7 and 7.1 km/h and two reverse gears (2.8 and 4 km/h), weight 60 kg. This model has an additional pulley mounting option and is equipped with rear and front linkage. A pulley makes it possible to drive various small-sized machines, including those used in livestock farming. On the rear linkage are hinged or hitched to it implements associated with the use of traction force (plow, ridger, semi-trailer, etc.), but the tractor can also be hitched to the rear linkage.). The tools and machines with active implements (mower, forage harvester, pump and others) can be mounted on the front machine and operated via the V-belt transmission.

Improvement of the KROT power tiller

For more high performance, I propose to set the MK 4-stroke engine manufactured in China LIFAN 160F, with a capacity of 4 hp. Increases engine power at low engine speeds. No more need to increase engine rpm to work the soil depth of 20 cm (according to the passport). Besides at the expense of power working depth has increased by 1.5 times and was about 30 cm. (up to belt slip). The engine easily copes with this task.

Another not insignificant advantage of this replacement. the engine starts when cold or hot. RPMs are automatically maintained at a preset level. At higher power consumption of gasoline remained approximately the same as that of the regular engine, besides now there is no need to add oil to gasoline (4-stroke engine).

The new motor is easy to install and modify. Engine mounts fit as standard. Pulley is taken from the old engine, the inner bore and keyway are slightly drilled.

Although the old engine gave me a hard time, the new one gives me a different feeling when working with the tractor!

Advantages of the machine

The single-axle tractor has been modified many times since the beginning of production. Old and new models have many decisive advantages:

  • Easy operation.
  • Great ergonomic features that make it easy to work.
  • Reliability of parts and assemblies.
  • The tractor can be adjusted to perform a variety of operations and tasks.
  • Low price.
  • Small dimensions that allow transporting it in a car and storing it in a shed or garage.
  • Long period of operation.

As a disadvantage, we can note the small width of the plot of land, which it captures for cultivation.

Operating instructions

The Mole petrol and electric cultivator is a reliable and functional device, but its service life depends on following the operating manual.

There are a number of rules that must be adhered to when using a power block.

Maintenance

Since gasoline models work due to the combustion of fuel mixture and engine oil, it is necessary to adhere to the factory proportions of components, creating a mixture. Otherwise the engine will soon fail.

Feedback from owners on thematic forums emphasize that you can not use analogues of the manufacturer’s recommended oil M-8B, because they do not have the required parameters.

Check that all fasteners are tightened and that the V-belt drive, reverse gear and operating systems are functional before you start the machine. Check the fuel and oil levels and, if necessary, assess the condition of the air filters.

During the first 15-20 hours the machine is running in with attached implements. During this period, it is allowed to use the machine with light loads and plow the ground in 2-3 times at a depth of no more than 10 cm.

Change the oil in the gearbox of the power unit after 5 hours of operation, in the gearbox of the chassis after 25 hours.

Further technical inspection involves basic maintenance with cleaning of the machine from contaminants and lubrication of the working units on the Krot cultivator with special oils.

Preparation for storage

If the Mole 2 will not be used for 2-3 months, it is important to get rid of the fuel mixture in the carburetor and perform a simple maintenance. If you want to leave the machine idle for a longer period of time you need to add 70 cc of engine oil in the cylinder and lightly turn the crankshaft.

The surface of mechanisms is wiped with a rag soaked in fuel mix.

Applications and possibilities of use

The Mole Tractor is specifically designed for a wide range of agricultural tasks in soil tillage. On country and homestead plots, on vegetable gardens and in subsidiary farms. The owners of these small “plots” know by experience that they can be turned over by hand only with great time and physical effort. A single-axis tractor “Mole” is precisely designed to save time, effort and health of its owner.

Main land cultivation operations are performed by the rotor with specially shaped blades. Torque is transmitted from the engine via a V-belt drive, gears and sprockets with a chain to the gearbox shaft with the rotors mounted on it. The rotor blades rotate and cut the soil, crumbling and mixing it.

Compared to a plough, a power tiller loosens soil better, crushes roots of weeds, as well as mixes organic and mineral fertilizers evenly with soil throughout the working depth. Producers assure that the “Mole” motocultivator can be used even in heavy soils and for the cultivation of virgin land.

Additional attachments significantly expand the scope of application of the Krot power tiller. In particular, it can be used for inter-row weeding; potato hoeing; mowing the grass.

The Mole single-axis tractor can also be used to pump water from open reservoirs and tanks. For this purpose a pumping device connected with a V-belt drive is installed on its frame. And with the traction reducer V-belt drive is removed. Pumping unit MNU-2, used for this work, of course, is purchased separately.

The Mole can also be of some use for transporting loads weighing up to 200 kg on a small cart “TM-200” with a swivel hitch. The rubber wheels are put on the gearbox output shafts. “Mole” is relatively easy to handle, does not require a large room for storage, and the insignificant weight and dimensions simplify its transportation.

What elements of the machine may require close attention of the operator?

And now let’s take a closer look at all those failures, which can affect the performance of the unit, whatever model it belongs to.

Won’t start

So, what to do if the Mole won’t start, and what are the possible reasons? The ignition fails, or is completely absent in the following cases:

  • No spark. This could mean that the spark plug is burned out. In this case you need to unscrew it and just replace it with a new working one.
  • Spark plug is smoky. It can be brought back to life by good cleaning (removing the soot, stripping the contact), and then the spark plug should be well washed in gasoline.
  • If the cultivator does not start, but the spark is there, then, most likely, the reason is the lack of insulation. Check the spark plug again. if it is wet or slightly damp. It is not necessary to change the whole spark plug, you just need to replace the tip.
  • Poor quality fuel can be the reason of the lack of ignition of the cultivator. This is the reason why the spark plug gets wet, after which you will have to replace the spark plug.
  • Fuel leaking from the spark plug is another reason why the machine won’t start. To correct the situation it is necessary to drain the cylinder by pumping the engine with a manual starter.
  • The lack of ignition may also be caused by problems with the hoses that feed the fuel. To restore the work of the motocultivator it is necessary either to tighten the hoses well, or, in case of rupture, replace them with new ones.
  • Poor insulation of the electrical system (high-voltage and low-voltage wires) can also be the reason that the unit does not start.
  • Pay attention to the air filter. If it is dirty, you will have ignition problems. You need to either clean it or replace it. often resort to the second option, goodness, this spare part is available both in terms of price and availability in the store.
  • Magneto failure itself. This part can not be repaired, it is immediately replaced with a new one. How to check the magneto of a Mole motocultivator to see if it is faulty? It’s very simple, if all the reasons for the absence of spark are excluded, then the reason for the malfunction is in the magneto. Many craftsmen remake working magnetos, thereby increasing their service life.

Here is how the ignition diagram of Magneto for Mole motocultivator may look like

  • Ignition may be absent if the flywheel plates undercut the magneto cores.
  • Improperly set the gap between the electrodes will not allow the spark to jump.

Engine

The main reasons that the motor “Mole” does not start, are:

  • lack of fuel (or its low quality);
  • problems with ignition, discussed above;
  • appearance of decompression and, as a result, piston wear, deformation of the exhaust valve.

In the first case, simply pour the required amount of fuel (a mixture of gasoline and oil M-8B Autolom) and all the problems will be resolved. In the case of violation of compression will have to fully dismantle the engine and replace the damaged parts, and this may be a piston, o-ring.

Deformation of the exhaust valve becomes another cause of compression failure, which leads first to a loss of power of the Mole motocultivator, and then to starting problems.

To restore the engine capacity you need to make its full disassembly. After assessing the condition of the piston, if necessary, replace it. Replace piston rings, exhaust valve. Examine the engine head, in particular the gas distribution mechanism, clean it if there is fouling. In the case of damage to the elements of the design replace them with serviceable.

The engine choice

In the Soviet Union were used only two-stroke single piston engines manufactured in Russia, not very powerful. Today it is possible to meet “Mole” with the four-stroke imported engine. But if you still have in your arsenal is the first model of cultivator, it is easy to upgrade your “Mole” by replacing the engine.

And then there is a new question: what engine is better to install on the machine? The answer is not difficult: the models used in newer machines are suitable.

Hammermann CF 168 F65 Engine GeoTec Engine Subaru Engine Honda GX160 Engine BriggsStratton 550 Engine Lifan 168 F-2

It is best to replace the domestic engine with an imported one:

Any of them will not only give a motocultivator a new life, but also significantly increase the power and service life of the unit.

A great solution would be to install the engine Lifan on the motor cultivator “Mole“. This motor provides the car a long life, because in addition to reliability and efficiency, Lifan stands out for its unpretentiousness and just do not require additional attention to themselves.

Adjustment of the carburetor is necessarily carried out after the first working season.

An adjustment of the carburettor is an essential part of the machine’s service. Thanks to the timely inspection and repair the service life of the cultivator will increase. Inspection and adjustment is also necessary if the engine roars heavily for no apparent reason.

Before proceeding to the adjustment, we should get acquainted with the structure of the carburetor of the cultivator “Mole”:

So, to adjust the fuel supply and provide the necessary speed, you need to turn to two screws: the number of revolutions (in Fig. ) and fuel quality (Fig. ). With the help of these two screws make the adjustment of the fuel supply to the carburetor of motocultivator “Mole” at idle speed. It is necessary to act very carefully, check the state of ignition beforehand.

Important! Thoroughly clean the carburetor, clean it where necessary, wash it and change parts where necessary. That way the Mole will last a long time.

The owners of the machine often wonder how to start the Mole cultivator after the winter. No ignition is caused by condensation in the carburetor that has accumulated during downtime at shifting temperatures. The solution is to completely disassemble the unit and then clean it. All sorts of additives in low-quality fuel and dust that has seeped through the filter will also not work.

Gearbox

The main task of the gearbox is to transmit the torque from the engine to the shaft. Transmission is carried out by means of a V-belt transmission. To learn more about the structure and repair of the gearbox of motocultivator “Mole” you can watch video.

Drive belts for the Mole cultivator can have different modifications, but their dimensions are strictly defined:
