Consider the top rating of heavy motoblocks, common and popular in Russia:
- Belarus 09 H-01. It has been produced in Minsk since 1992. A HONDA engine running on gasoline is used. Has 4 forward and 2 reverse speeds, the ability to completely lock the wheels. This is a simple, high quality and reliable unit. Of the minuses, you can only determine the manual start and considerable fuel consumption.
- Herz DPT1G-135E. Chinese walk-behind tractor with a high-power diesel engine. This device is slightly cheaper than the previous version, but there is no differential in the package. It is difficult to quickly repair and maintain, since this brand is not very common and there are not enough service centers. The engine is economical enough to save on fuel.
- PATRIOT Boston 9DE. Manufactured in China. The power of the diesel engine is 9 horsepower. It has only 2 speeds available, which does not prevent the unit from performing heavy work, even with very dense soil. The gripping span reaches 1.25 meters, the equipment is economical and durable, and allows a low noise level. Timely maintenance will allow you to use the walk-behind tractor for many years.
- Sich MB-8. Made by a Zaporozhye company. It has a gasoline engine and weighs 112 kilograms. The power is 8 hp. The technique is passable, durable and maneuverable. The steering is adjustable for increased driving comfort.
- Aurora COUNTRY 1400. Slightly lighter in weight than the Sich MB-8, but the device has a super power of 13 horsepower. Because of this, it can work the land immediately at a width of 1.7 meters, which significantly speeds up the process of plowing and harvesting. For even higher productivity, it is recommended to use additional attachments.
- Hopper. There are many suspension devices in the package. It is used for plowing heavy soil, pumping fluids, cleaning the area from objects and debris. With its compactness, the unit is very powerful and runs on a diesel engine.
- Bison. It comes in a simple configuration, with additional water cooling, a more complex gearbox, an enlarged cutter. There are 2 rows of speed selection and the possibility of using additional devices. The power of the walk-behind tractor is 8 hp, very comfortable control.
- The foreman. Diesel vehicles manufactured in Russia. A special halogen headlight allows work to be carried out at any time of the day. Power reaches 10 hp, economical fuel consumption at high revs.
- MB-12 DEL. It has a diesel engine with a power of 12 hp, a starter can be either manual or electric, improved transmission, power take-off shaft.
- Neva-23SD-27. A Japanese motor is used. The large diameter of the rims allows you to feel stable on any surface. There are 6 forward and 2 reverse speeds.
It's interesting: what kind of oil to pour into the engine of the walk-behind tractor.
The difference between a cultivator and a walk-behind tractor
The difference between a walk-behind cultivator and a walk-behind tractor lies in their power and performance. So, for example, a motor cultivator uses only cutters. They are needed to loosen the soil - this is the main and, perhaps, the only purpose of the cultivator.
Of course, if you bought a professional heavy cultivator, you can also buy rubber wheels with it.
If you have a lightweight cultivator, you can get by with cutters.
Type of cultivators
- medium motor cultivators
- heavy (professional) motor cultivators
The engines of the light versions have a power of 4 hp. with cultivators weighing 30 kg. Medium units weigh between 50 and 90 kg and have 5-7 hp engines.The power of heavy cultivators is from 8 HP, and the weight is over 80 kg.
They are categorized by power and engine type. So, light and medium cultivators have 2-stroke gasoline engines.
Light cultivators may have an electric motor, although these are very limited in their capabilities. If you have a land plot of up to 6 acres, then a light cultivator is more likely to suit you.
The heavy ones have a 4-stroke gasoline engine. Very rarely - diesel.

Heavy machinery
Heavy walk-behind tractor (the most powerful) more than justifies its name. The mass of such equipment ranges from 150-200 kilograms, and the engine power is 10-13 liters. with., which allows you to pull the plow and transport loaded carts without any weighting materials.
The dimensions of the equipment and the available weight force manufacturers to install a differential transmission, therefore, it will no longer be possible to deploy such a machine on one wheel, as is the case with a light group. It is also quite common to find models with a reduced gear in the gearbox, which slightly fits the general performance characteristics.
The most powerful walk-behind tractor in the world is the Profi PR 1040E series (according to famous agricultural magazines). This model is, in fact, a mini-tractor with an engine capacity of almost 600 cubic meters and a capacity of 10 liters. with.Three hundredweight of weight, impressive dimensions and a price well over 100 thousand rubles did not add to its popularity, therefore, the domestic consumer prefers equipment that is more classical in terms of design and cost.
Next, we will consider the most powerful motoblocks in Russia of different groups and manufacturers. We will also outline the main advantages and disadvantages of each individual model.
Gasoline models of walk-behind tractors
MB-105 (7 horsepower)
This is a walk-behind tractor with a 7 horsepower HMS170F gasoline engine. The engine is started with a recoil starter.
Motoblock Kubanets MB-105 7.hp
- The volume of the fuel tank of the MB-105 walk-behind tractor is 6.5 liters.
- The maximum width of the milling cutters is from 80 to 105 cm.Their immersion depth can be adjusted from 15 to 30 cm.
- The weight of the MB-105 walk-behind tractor is 138 kg.
MB-105 (9 horsepower)
This device has a similar appearance to the previous model, but differs in power and weight.
Motoblock Kubanets MB-105 9.hp
- The gasoline engine of the MB-105 walk-behind tractor is called HMS177F and has 9 horsepower.
- The device weighs 150 kg.
- This walk-behind tractor can be successfully used even on the most difficult soils.
MB-1050
This device is a lightweight semi-professional model.
- The weight of the MB-1050 is 82 kg. Because of this, it can only work with light soils.
- Motoblock MB-1050 has a gasoline engine with a capacity of 7 horsepower.
- Milling widths range from 80 to 105 cm.
MB-500
- It is a lightweight model for small areas.
- Its weight is 80 kg, and the power of the HMS170F motor is 7 horsepower.
- The greatest width of soil processing with milling cutters and MB-1500 walk-behind tractor is 1 m.
- PTO is not provided on this model.
MB-900
This model has identical characteristics with the MB-500 walk-behind tractor, however, a power take-off shaft is installed here. Because of this, the weight increased to 85 kg.
MB-950
Based on the reviews, the manufacturer noticed that the MB-500 and MB-900 models were not very practical. And when receiving heavy loads, the device cannot withstand them. To correct these moments, the MB-950 walk-behind tractor was released with an improved cast-iron gearbox and a reinforced hitch.
This device is intended for use on a site with an area of 20 acres.
Specifications
Despite the fact that diesel engines are used in heavy motoblocks, a gasoline alternative still exists. Each of these types of engines has its own characteristics. Gasoline engines are equipped with small and medium-sized walk-behind tractors, less often heavy ones.
Accordingly, such an acquisition has a long payback period. Although the prices for the gasoline units themselves are slightly lower than diesel ones.
The weight of the gasoline engine is less, which implies a lower weight of the walk-behind tractor itself with the same power. This technique is more maneuverable, but the engines themselves do not perform well during prolonged operation at low speeds. In addition, the cooling system of this device is simple and also not designed to carry out work for a long time.
The optimal load for a gasoline engine is an area of up to 1 hectare. However, the technical characteristics of heavy gasoline motoblocks indicate an area of 3 hectares with a power of 8 liters. with.
There are also significant advantages to this technique. For people who do not have a driver's license and are far from shifting gears and the need to squeeze the clutch, there are modifications with an automatic transmission.
And the fuel consumption with modern technologies is quite low. But the most important quality of such a walk-behind tractor is endurance. The machine can handle large areas of land without overloading. The cooling system of such a device is large, the horsepower supply is also pleasing. The power of such engines reaches 18 liters. with. At the same time, experts say that the speed of the units is not small - up to 20 km / h.
For owners of private farms, the possibility of year-round operation is important, in contrast to summer residents. The latter are limited to planting and harvesting during the warm season. And farmers can be advised to acquire a heated storage room for such equipment. Also, manufacturers often equip heavy diesel engines with a power take-off shaft, which makes it easy to drive a trailed one. Complete set of large units of 10-12 liters. with. also involves the installation of an adapter for a comfortable ride and work.
Malfunctions of engine systems when starting
In the event that, when checking the candles, they turned out to be wet, i.e. the fuel flows normally, but the engine does not start, the problem may be as follows:
- Failure of the ignition system:
- there is a characteristic carbon deposit on the spark plug electrodes (it is necessary to clean the candles with emery, after which they should be rinsed with gasoline and dried);
- the size of the gap between the electrodes does not correspond to that specified by the manufacturer in the engine operation manual (the gap is adjusted by bending the side electrode to the required dimensions);
- insulators for spark plugs or high-voltage wiring are damaged (defective plugs and wiring must be replaced);
- the STOP button is shorted to ground (for normal engine start, the short circuit must be removed);
- contacts in the angles of the candles are broken (contacts should be put in order);
- the gap between the magnetic shoe and the starter does not correspond to the standard value (gap adjustment is required);
- defects were found on the stator of the ignition system (the stator must be replaced).
- Air leaks through the seals of the carburetor, spark plugs, spark plug heads and cylinders, as well as the carburetor and engine cylinder connections.
If a leak is detected in the connections, it is necessary to tighten the fastening bolts, tighten the candles and check the integrity of the gaskets between the plug heads and the cylinders.
- Incomplete closure of the carburetor choke.
To eliminate this problem, it is necessary to ensure free movement of the damper by checking the quality of the drive. If jams are found, they must be eliminated.
Compression and carburetor malfunctions
It so happens that the launch is carried out, but its process is significantly complicated. At the same time, the engine of the walk-behind tractor is extremely unstable and cannot develop sufficient power for normal operation.
The reason for this may be loss of compression, which can be identified by:
- soot on the working surfaces of the valves, as well as the seats of the cylinder blocks;
- deformation of the intake valve;
- wear of the piston rings.
In order to restore compression, you must:
- Check the technical condition of the engine timing mechanism, clean the parts contaminated with carbon deposits, and if there are any defects, replace them.
- Check the condition of the piston rings and replace defective components.
If black smoke comes out of the muffler during engine operation, and an excess of oil is detected on the spark plug electrodes, or they themselves are covered with carbon deposits, this means that:
- an oversaturated fuel mixture is fed to the carburetor;
- the sealing of the carburetor fuel valve is broken;
- the oil scraper ring of the piston is worn out;
- the air filter is clogged.
To fix this problem, you should:
- adjust the carburetor;
- replace the leaky valve;
- replace worn piston rings;
- clean or replace a defective air filter.
In the event that, when the engine is running, light smoke comes out of the muffler, and the electrodes of the spark plugs are dry and covered with a white coating, this means that a lean fuel mixture enters the carburetor. This problem is eliminated by adjusting the carburetor operation.
