What engine can be put on the “Mole” cultivator: replacement options

Motor-cultivators “Krot” are popular among owners of small land plots. This inexpensive and reliable technique has a simple design that many farmers make adjustments to. Among the improvements made is the replacement of the engine with a more powerful analogue.

Introduction:

For a long time, the mole cultivator has earned the fame of a reliable technique and a convenient cultivator, which is so multifunctional that many people call it a single-axle mole tractor. The only weak point of the mole walk-behind tractor is the old two-stroke engine, which was copied from the Japanese Kyoti kerosene engine of 1956. This engine was too low power, only 2.3 horsepower, designed for 76th leaded gasoline. Due to the fact that both 76th gasoline is now a rarity, and leaded (containing lead) gasoline is prohibited, the reliability of the old mole engine tends to zero. But do not throw such a wonderful cultivator-single-axle tractor mole into scrap metal! The modern inexpensive and correct solution is to replace the engine on a mole with a new one. Using the example of one installation of the engine on a mole, we will dispel your doubts whether the engine is suitable for a mole, and which engine is suitable for a single-axle tractor, a mole.

The Mole units are made in Russia. This agricultural technique is made at the Moscow plant of JSC “MMP im. V.V. Chernyshev “. The company has been producing engines for military aircraft since the 30s of the last century.

At summer cottages, garden gasoline four-stroke or two-stroke equipment is widely used, for example

The first “Mole” walk-behind tractors were produced in 1983. This technique is designed for soil cultivation. Later, the manufacturer began to produce attachments that significantly expand the capabilities of walk-behind tractors.

Compression recovery

If you have purchased a Krot motor-cultivator, the engine may need to be repaired after a while. When the consumer is faced with the above problems, it is necessary to analyze what is the state of the motor gas distribution mechanism. Parts on which carbon deposits have settled must be cleaned. If some parts are damaged, they need to be replaced. The operator should check how well the piston rings are intact. In the event of a malfunction of this unit, it will need to be replaced.

There are practically no unnecessary parts in the configuration of the domestic unit, however, the design of the cultivator is made in such a way that the owner can use it for a variety of economic purposes. Due to the reliability of the main components, the equipment is able to withstand prolonged loads. The unit design consists of the following elements:

  • The frame, which is connected from two semi-frames, is attached to the gearbox housing with bolts;
  • Tubular handle and bracket for the operation of attachments;
  • Control levers;
  • Pneumatic wheels, which are mounted on the output shafts of the gearbox;

What motors are suitable for installation on the Mole cultivator?

Among suitable engines for most Mole units, the following models stand out:

Replacing the engine on the Krot cultivator. selection and installation

The Krot motor-cultivator has earned the trust of customers due to its reliability and simplicity of design. Nevertheless, many farmers are trying in every possible way to improve the unit, improve its technical characteristics and operational indicators.

To do this, you can purchase and install a new engine for the Mole cultivator. it will make the unit more powerful, which will positively affect its performance and capabilities.

Lifan 168 FB motor

Power 6.5 hp from. with 2 cm pulley shaft. Some configurations have a shaft 1.9 cm long.

The engine air filter should be equipped with an oil bath to help reduce the load on the engine in dusty terrain.

Self-replacement of the engine. instructions and nuances

To change a regular motor to an imported one, you need to follow the instructions. The correct algorithm is as follows:

  • First, unscrew the factory motor mount, remove the gas and muffler wires;
  • Remove the engine from the frame;
  • Attach a new motor and mark on the frame where you need to drill holes;
  • Install the new motor, put the belt on it and slide it along the frame to the maximum belt tension. Make sure that the motor pulley and the gear pulley are in the same plane;
  • Bolt the motor to the frame.
  • Connect the transmission channels.

Before work, the finished structure should be “run” at idle speed.

Patriot motor

In addition, you can install a Patriot electric motor for the Mole walk-behind tractor, The only thing is that you need to take care of electricity in your area so that the device can work stably.

Lifan

As practice shows, you need to take with a pulley shaft of 20 mm (there is another type of engine for 19 mm). It is also important to have an oil bath at the air filter, because such a device is used specifically for areas where there is increased dustiness.

How to convert a Mole to an electric motor, installing a Lifan Engine on a uniaxial tractor. replacing it with an imported one

The agricultural industry is gradually entering the means of small-scale mechanization, which makes it possible to significantly simplify the process of carrying out land works.

An important role in this is played by motoblocks from various manufacturers, distinguished by their compactness and relatively high power, depending on the type of engine used. In our country, traditionally popular are domestic units, familiar to many since Soviet times.

In particular, we are talking about the Mole walk-behind tractor, which is the first model, the serial production of which was established in the USSR.

However, many are not happy with the factory engine included in the kit, wanting to replace it with a more powerful one.

This does not mean at all about the poor performance of the “native” motor, but some want to put a more powerful unit. Consider this issue from all sides, taking into account the technical features of the complete set of the Mole walk-behind tractor, and also find out which engine can be put on it.

Instructions for replacing and installing the engine on a uniaxial tractor

This is a perfectly acceptable option for those who have extra funds, but we will consider the option of directly installing the new engine on the Mole frame structure.

Let’s take an example of the 4-stroke Forza 160F engine, which has 4 hp. This choice is not accidental, because it runs on standard AI-92 gasoline, which is more preferable than the mixture used on the Mole’s factory engine.

This engine for a single-axle tractor Krot also has increased technical data, which naturally affects its cost. average

This engine has the following technical characteristics:

  • the type of fuel used. gasoline;
  • maximum power. 4 hp;
  • total weight. 13 kg;
  • length. 40 cm;
  • width. 33 cm;
  • height. 35.5 cm;
  • fuel tank volume. 3.2 l;
  • oil sump capacity. 0.6 l.

These technical data are an order of magnitude superior to those of the “native” motor.

Now you can start working, the algorithm of actions will be as follows:

  • On the Mole walk-behind tractor, you need to unscrew the fasteners of the factory engine, which consists of four bolts. You also need to remove the jamming and gas wires.
  • Removing the factory engine from the frame.
  • The problem is that the old holes on the frame do not line up with the mounting holes on the new engine. We need to mark the points that we will drill on the frame structure.
  • We take a new engine and put it on the frame. We put the belt on it, then we move the motor further along the frame to the desired belt tension. it should turn freely. We leave the engine in this position and mark the places in which two through holes will be made. You also need to ensure that the motor pulley and the gear pulley are on the same plane.
  • Next, we drill holes along the pre-marked grooves. By the way, to connect the engine to the frame, you need to use bolts 3.5 cm long, which is the optimal value for our purposes. Longer bolts simply won’t fit between the frame and the underside of the engine.
  • We tighten the two bolts all the way, connect the clutch, gas and jamming system.

The only difficulty is that the size of the pulley on the walk-behind tractor does not match the shaft of our new engine. You can replace the pulley, but there is the possibility of some revision of the old one. you need to slightly bore the hole of the pulley so that it fits under the motor shaft.

It is important to maintain the alignment of both pulleys here, so it may be necessary to install centering stands.

Thus, we have got a single-axle Mole tractor with a rather powerful imported engine. At the same time, its weight became slightly higher, but the performance characteristics increased significantly.

In the course of work, the new engine recycles the soil much deeper and more intensively, in comparison with the factory unit.

At the same time, it is better not to immediately start intensive work, letting the engine run a little, getting used to new conditions.

What kind of electric motor can you put on a Mole cultivator?

The design of the Mole walk-behind tractor frame allows you to install other engines produced at various factories on it. At the same time, the alteration of the frame will be minimal, consisting in a few simple manipulations.

Motor cultivator device

The Mole motor-cultivator, as well as the Caiman, Patriot, Texas, Foreman, Krosser, VIKING, Forza walk-behind tractors, is quite popular in the post-Soviet space, which is explained by the simplicity of its design and rather good performance.

There is absolutely nothing superfluous in the complete set of this walk-behind tractor, but its device is made in such a way that it is able to cope with the main agricultural work. digging beds, cultivating the soil, etc.

In addition, the design of the main working units allows it to withstand fairly long-term loads, ensuring stable operation for many years.

For more information about the Mole walk-behind tractor, see

The very design of the Mole walk-behind tractor consists of the following components:

  • Frame structure, consisting of two half frames, bolted to the gearbox.
  • Tubular handles, as well as a special bracket for attaching additional attachments, located at the back of the structure.
  • The main controls are located on the handles. adjusting the engine speed, as well as the clutch.
  • Tillers can be put on the output shafts of the gearbox, as well as wheels that allow the use of a single-axle tractor with a plow, or for transporting various loads.
  • On the frame structure there is a motor for the Mole walk-behind tractor, which is connected to the input shaft of the gearbox through a V-belt transmission.
  • In addition, the design has built-in wheels that allow the unit to move freely. When starting work with a walk-behind tractor, these wheels must be removed from the structure, or raised and fixed in the desired position.

As we can see, the device is quite simple and does not include unnecessary frills. In principle, everything that is needed for high-quality work on the ground. all this is in the design of this unit and in the Sadko, Don, Huter, Profi, LANDER, Champion walk-behind tractors.

As for the factory engine of the Mole walk-behind tractor, its device is a 2-stroke engine with one cylinder and air cooling.

Its volume is about 60 cm3, with a power of 2.6 hp. and 6000 rpm. It starts with a regular cable, according to the principle of a chainsaw plant.

You need to fill it with a special mixture consisting of gasoline and engine oil. These characteristics are rather modest, so many people want to change it to more powerful models.

Replacing the factory engine can be done independently, because the design of the Mole, as mentioned above, does not present a certain complexity in its understanding. Most often, they resort to replacing them with 4-stroke versions of engines, because they have higher performance than 2-stroke.

Of course, there are some modifications, such as a single-axle Mole tractor with a 4-stroke Honda engine, but its cost will be significantly higher than that of a standard Mole. Therefore, we are considering the “worst” option, when we have a single-axle tractor with the most standard factory engine, with a capacity of no more than 3 hp.

Sadko

A good option is obtained from the installation of the SadkoDE-220 engine on this single-axle tractor, the power of which is about 4.2 hp. Shaft diameter is 19 mm, cord starts.

An electric sprayer is an important and highly effective tool in the competent organization of labor in a garden area, which allows you to protect the plant, feed it on time and carry out prevention. By clicking on the link you will learn how to make a sprayer with your own hands.

In principle, these are the most optimal engine options that can be installed on the Mole. In principle, you can try to install other models, but it is important to remember that their power should not be too high.

In principle, 6 horsepower is quite enough for such a walk-behind tractor design, because the use of large powers can bring an unnecessary load on the gearbox, which can cause it to fail quickly enough.

the single-axle tractor Mole is distinguished not only by its unpretentiousness and acceptable performance, but also by the ability to install a variety of engines on it.

This became available because the Mole’s frame structure has a fairly simple structure, on which other power units can be freely installed.

At the same time, manipulations are reduced to making holes with the help of a conventional drill, which is in the household of the majority of the male population of our country.

With such a rework, you can achieve a significant increase in the performance of the walk-behind tractor without buying a new unit. All costs will be reduced only to the purchase of an internal combustion engine, suitable for technical data.

Thus, it is possible to achieve virtually identical performance indicators with foreign-made walk-behind tractors without spending a lot of money on it.

Patriot motor

In addition, you can install a Patriot electric motor for the Mole walk-behind tractor, The only thing is that you need to take care of electricity in your area so that the device can work stably.

Principles of use

the single-axle tractor Mole has a standard operating principle. Rotary cutters installed on the gearbox shaft are responsible for treating the soil in various ways. Torque from the power plant is transmitted to it through a V-belt transmission.

The cutters themselves are medium-sharpened blades that, through rotation, cut the soil layers, which are then mixed. During this process, the cultivator does not stand still, but must move forward.

According to the operating rules, the cultivator must have a vertical position during operation. Otherwise, oil may spill out of the gearbox and enter the air filter. In addition, it is important to remember that the manufacturer does not recommend using a single-axle tractor at full power immediately, as this is detrimental to its parts. To give them a break-in, it is necessary to run in, which consists of several important steps:

  • checking internal and external parts before the first start
  • checking the fuel and oil level in the engine
  • having started the engine for the first time, you need to let it run for 30-40 minutes at idle
  • operation of the walk-behind tractor, its work with the soil. Soil processing is allowed in different ways. cultivation, plowing, mowing, hilling, etc. The run-in lasts an average of 10-15 hours. During this process, the oil and fuel levels should be checked in a timely manner, as well as the condition of the undercarriage. It is very important to check the gearshift mechanism. how clearly they engage, whether there are any vibrations or extraneous noise.

After running-in, it is advisable to conduct a repeated technical inspection of the product. As practice shows, compliance with all these procedures will allow the internal parts to work in, and thereby extend their service life.

What engine to put on a mole

General information, purpose and design features

The single-axle tractor Krot is designed for soil cultivation in various ways, including hilling, plowing, mowing and cultivating the soil. Also, a single-axle tractor is capable of transporting small loads over short distances, and processing virgin soil and other complex types of soil, and to great depths. However, this is possible if additional weighting materials are available. for example, ground hooks.

The mole is a universal apparatus. Its design supports a large number of options, and thanks to this, the model is endowed with almost unlimited possibilities.

The model under consideration, like the rest of the motoblocks of the family of the same name, has a similar design. The machine uses a gear reduction mechanism to which tubular handles and a special bracket are attached. The latter is necessary to install attachments.

The handle of the walk-behind tractor has a special shape. It contains various controls. levers responsible for gas, brake, gear selection, ignition, etc. The single-axle tractor is equipped with pneumatic wheels that increase the off-road capabilities of the machine. The wheels can be dismantled, and in their place put metal wheels with soil hooks.

In addition to the bracket, cutters are a tool for installing additional equipment. The more there are, the more add-on options can be installed. In addition, the milling cutters allow you to work the soil to a depth of 250 mm.

The Mole cultivator is equipped with a power unit that is manually started using a special rope and an air cleaner with an air filter. The capacity of the fuel tank is 1.8 liters. The manufacturer recommends filling in low-octane gasoline.

“Mole” has several modifications that differ in equipment and performance. For example, depending on the version, different power plants can be used. both domestic and imported. All engines are single-cylinder, 4-stroke, carburetor, with their own cooling system.

In addition, a small-scale production of Mole walk-behind tractors equipped with electric motors has been established. In such machines, electricity is supplied using cables. Such models are especially common in greenhouses, as they have zero harmful emissions.

over, electric “Moles” are more convenient to use, and despite the electric motor and weak batteries, they are endowed with a decent power reserve.

Lifan

As practice shows, you need to take with a pulley shaft of 20 mm (there is another type of engine for 19 mm). It is also important to have an oil bath at the air filter, because such a device is used specifically for areas where there is increased dustiness.

Cultivator Mole

The mole is a popular cultivator. than 30 years have passed since its inception. This model is considered one of the most popular in the post-Soviet space. Many manufacturers still follow the example of this cultivator. It has a classic design, and due to this, it is as easy to maintain as possible, and does not cause problems in long-term operation. The machine is in high demand in the Russian market, as well as in the CIS countries.

Which engine is suitable for the Mole walk-behind tractor

The “weak link” of the Mole walk-behind tractor is the engine, which lacks performance, and it starts badly. The owners of the unit are trying to solve this problem on their own.

The design of the Mole frame allows you to replace the engine with a device from another manufacturer. Alterations will be required minimal and uncomplicated, so they are quite within the power for independent execution. In most cases, the engine of the standard complete set of the walk-behind tractor is replaced by 4-stroke models with better performance.

The Patriot engine is a good solution. It will be inexpensive. The only condition is the presence of electrical wiring on the site.

The Honda GC 135 engine is suitable for all working conditions and consumes little fuel. The professional design of the 4-stroke motor has a single block aluminum cylinder with a toothed drive belt. Differs in lightness and environmental friendliness.

The Sadko DE-220 engine is suitable for installation on a single-axle tractor Mole. Its power is about 4.2 liters. c and an output shaft with a diameter of 19 mm, so the pulley will have to be modified. The device is launched through a cord.

The 4-stroke Forza 160F 4 hp engine has improved technical data. from. To work, he needs gasoline of the AI-92 brand.

The motor for the Mole walk-behind tractor can also be installed on other models, but only of low power. It is enough to limit yourself to 6 liters. from. Powerful motor overloads the gearbox and leads to damage.

Rules for choosing and installing an engine for a Mole walk-behind tractor

To simplify the cultivation of land and various agricultural operations in subsidiary plots, mechanization tools are used, such as the single-axle Mole tractor. The device successfully copes with the cultivation and loosening of the soil, weeding between rows and weeds, hilling potatoes and transporting goods. Differs in simplicity and reliability in operation, mobility and small dimensions, which is convenient for transportation in the trunk of a car, durability and versatility.

Engine description

In the classic version, the Mole engine is a single-cylinder, two-stroke with a carburetor and forced air cooling.

The motor is equipped with a non-removable starter. Starts manually using a cable like a chainsaw.

  • Working volume. 60 cubic meters cm;
  • Power. 2.6 hp / 1.91 kW;
  • Rotation frequency. 5500-6000 rpm;
  • Average fuel consumption. 0.96 l / kWh;
  • Fuel tank capacity. 1.8 liters;

Carburetor device. as on mopeds of the Soviet period Riga “,” Verkhovyna “or” Karpaty “.

The motor uses a dry air cleaner with a replaceable filter element.

It should be refueled with A-76 low-octane gasoline with the addition of M-8V1 (autol) engine oil, keeping the ratio 1:20.

Ignition is non-contact, electronic model “MB-1”, as on Soviet chainsaws with a candle “A-17V”. Installation of the “A-11” spark plug ensures stable engine operation without carbon formation.

Modifications of the Krot walk-behind tractor are equipped with more powerful 4-stroke engines made in China.

Walk-behind tractor device

the single-axle tractor Mole is a frame structure divided into two semi-frames. At the top are the pipe-type handles and an attachment bracket located at the rear. The controls are located on the handles: the clutch and the speed switch. Some models also have a reverse switch.

The device is equipped with four cutters, 2 external and 2 internal, as well as a coulter. Additionally, a bed hiller, a potato digger or plow, a pump for water supply, a mower is installed.

A two-stage gear-type gearbox with a chain drive and an internal combustion engine are bolted to the base frame, which are connected by a V-belt transmission. There is a fuel tank above them.

The clutch of the minitractor is turned off and is switched with a handle like on a moped. Engaging the clutch provides tension on the belt for torque transmission without slipping.

Milling cutters for soil cultivation or wheels for moving loads or joint use with a plow are mounted on the output shafts of the gearbox. The cutters serve as the main working body and represent a rotor with special knives. They rotate and cut, crush and mix the soil as they move forward gradually. The working depth will depend on the length of the opener used.

The tiller loosens the soil more thoroughly and mixes the fertilizer in comparison with the plow. Shows good performance on heavy soils and virgin soil.

single-axle tractor Mole moves freely on built-in wheels. Before starting work, they are removed or raised, fixing in the desired position. Do not give full load during the first 15 hours of operation. At this time, the parts are running in. At a “bump” pace of use immediately after purchase, the performance of the motor decreases.

How to replace

The trouble-free operation of the mini tractor will depend on the observance of the sequence of installation and connection.

  • Unscrew the factory mount and remove the cover.
  • Disconnect the wires and disconnect the belt.
  • Dismantle.
  • Attach a new engine and mark the new mounting holes on the frame.
  • Install the engine and put on the belt.
  • Adjust the belt tension by moving the motor.
  • Align the unit so that the pulley of the motor and gearbox are in the same plane and coaxial.
  • Drill through holes and fix the walk-behind tractor engine with 35 mm bolts.
  • Connect clutch, gas and muffler system.
  • Run-in at idle speed.

About the disadvantages of the walk-behind tractor

The multifunctional single-axle tractor Mole has its drawbacks:
