Design and operating principle

In order to better understand the principle of the work of the tractor of the walk behavior, it is first worth taking into account its design. The aggregate frame contains two half rams that are attached to the gear with screws. In the rear area there are the control handles of the tube control and a special bracket with which additional devices can be attached if necessary. The control of the device is on the handles.

At the weekend of the waves, mills can be displayed that enable floor plowing, weeds or wheels. The engine, which is connected to the transmission with the gear input shaft, is located under the frame. There is a fuel tank in the upper part of the frame. The lever wheels are used to roll the hiking facilities, and they must either be removed or raised during operation.

It is worth paying attention to the carburetor of the Walk behavior, since it is simply indispensable because it fulfills the control of the air and fuel flows. With its help, the functioning of the engine is optimized when the load is constant. Since the engine cannot ignite without oxygen supply, the presence of a carburetor remains unchanged.

The air purifier is also one of the main components of the tractor of the walk behavior because it carries out the cleaning of the air into the carburetor. If the air filter is clogged with dust and various dirt, the fuel is impoverished, which leads to problems in engine operation.

Now more about the operation principle of the Kroto f-Motoblocks. The rotating movement generated by the engine goes through the V-belt to the gear and is then transferred to the starting waves. When the operator switches on the device, the clutch is triggered while the belt is pulled and the gear shaft is started accordingly. It is worth noting that the device works inactive when the clutch is separated. On the shafts of the gear are tailors that are equipped with knives.

Krotoff WG912

This walk behind tractor is an improved version of the 901 model with electric start.


Motoblocks Krotoff gained great popularity due to a wide range of applications. In areas of small and medium size, they can replace a full-fledged tractor. At the same time, the advantages of its operation are obvious: it is smaller, more economical, cheaper and cheaper parts for it. And the working spectrum gives exactly the same thing.


This attachment is considered basic and is sold with most Krotof walk-behind tractors. The knives mix the top layer of soil and thus increase the yield.

Cultivator cutter Houndstooth cutter

The manufacturer offers saber cutters, but these have recently given way to crow’s feet. They are also fitted in place of standard pneumatic wheels but have a different design. Steel rods are welded to the metal shaft, at the end of which triangular plates are attached. In appearance, these cutters resemble exactly “crow’s feet”.

If there is a need to work with virgin land, then the first processing is best done with a plow. This attachment is known to our great-grandfathers. Now it has simply taken on a different appearance and instead of a horse, a Krotof two-wheel tractor is used.

Plow Reversible plow with two shares

With reversible plows you can break up large blocks of earth and only then throw the layer of earth to the side.


The lush growth of grass in summer means a lot of effort when cleaning. Krotoff walk behind tractors along with mower decks can help with this.

The most commonly used rotation options. They cut grass thanks to rotating blades. These models can handle medium-sized young grass and small shrubs.

Segment mower rotary mower

Segment mowers can deal with dense weeds in untouched areas. They are capable of trimming even large weeds and medium sized shrubs. Sectional mowers cut grass with two rows of triangular blades that move towards each other.

Mowers with walk-behind tractors from Krotof are used not only in rural areas, but also in municipal works.

Potato digger Potato planter

Motoblocks Krotoff can make agricultural work with potatoes easier.

Potato planters are designed for planting fruit in the ground. Most often they work on the following principle: the plow makes a ditch, then fruits are fed from the tank and planted at an equal distance, and two hillers at the end bury the ditch. Potato planters are actively used when planting potatoes on medium or large areas.

Potato digger Potato planter

After the root crops are ripe, they should be dug up. For this purpose, a potato harvester is attached to the Krotoff two-wheel tractor. The simplest option takes the form of a plow with welded steel bars (they are popularly called sieves). During movement, the plow raises the lower layer of soil along with the potatoes, and the bars break large blocks, leaving only fruit on the surface.

Snow blower and blade shovel

In heavy snowfall, Krotoff walk-behind tractors with special attachments can help clear snow.

Professional snow breakdowns are used in cases where a large number of precipitation falls or a large area of ​​the floor must be removed. They absorb a layer of snow and throw them through the gutter.

Snowman for an engine blockpflugman

If it is necessary to only remove your website and the snow cover does not increase over 20 cm. In winter you can use an ordinary blade blade instead of snowball players. Your direct purpose is to compensate for sand grains during the construction, but in winter you can finish snow cleaning.

Wheels, floor and caterpillars

In the standard configuration, the Krotoff mot blocks are equipped with pneumatic bikes with a wide profile. You can deliver devices to the location for the operation or transport of goods. However, a problem with inadequate coupling with the surface often occurs during work.

Grunzacups Caterpillar module Wheel 4×10

Soil rooms can solve this shade. They are metal slices on which steel plates are welded along the contour in the form of letter V. When driving, enter the floor and help to move forward.

Another problem occurs in the winter season. Fixed ice is formed under a layer of snow. And the ceremonies don’t help here. Instead, you can install caterpillars. They not only increase the clutch with the surface, but also the contact area.

Adapter and trailer

The owners are very tired while operating the Motoblok mroff with elevated loads or in large areas. Adapter can partially reduce the operator’s load. This is a special prefix with a seat with which you can manage sitting.

Pendants are used during the transport of goods by the Krotof Motoblock. The manufacturer offers sel f-specific options that can make the discharge process easier.


A special feature of Motobog Mrotof is the fact that you have a universal coupling with which you can use attachments from other manufacturers (NEVA, cascade, MTZ, etc.).

Clusting Cargoes Universal Double


If it is necessary to increase the clutch of the Walk behavior tractor with the surface, but there is no desire to install floor or caterpillars, weight can be used. Factory models are made in the form of pancakes and hung on a wheel axle. Alternative you can use any heavy object that is at hand.

operation and maintenance

The new owners of the Motobobok Crotoff must examine the operating instructions. There is the main data of the manufacturer for the properties of the device, its device, the sequence of the assembly and running, the operating nuances and the schedule of the preventive work.

This video check shows the process of compilation of factory mills:


Before you start using, you should definitely familiarize yourself with the user administration. After assembling the Krotof motor block, be sure to pay attention to fuel and petrol. Many owners forget it and immediately hear a strange sound from the engine.

After that it is necessary to run. With this procedure, the motor details can clearly stand in the right grooves and enter into each other, since there are necessarily small mistakes in the factory assembly.

According to the user manual, the run should occur within 5 mothers.

At this point it is necessary to use a tractor at low speed and with minimal loads. Riding with an empty trailer or plowing in a minimal depth of soft soil is considered ideal.


So that the motoblock crotoff serves as long as possible, it is necessary to carry out preventive work in accordance with the manufacturer’s recommendations.

  • Replacing the engine oil should occur every 25 hours after operating the device. The operating management recommends using 10W-40 or 10W-30.
  • The transmission oil should be changed less frequently after 100 hours of operation. TAD-17i or TAP-15V are considered ideal replacement options.
  • Control levers should be treated regularly with waterproof lubricant to reduce the friction on them and prevent rust and jamming. The motoblock crotoff is unpretentious in this regard and you can use litol-24 or solidol.
  • For gasoline models, it is necessary to use AI 92 fuel with a high octane.

The main disorders

Every owner of the Krotof Motoblock must know the possibilities to eliminate the main disorders.

If the engine does not start:

  • Check the presence of fuel in the tank;
  • Perhaps the Benzocran accidentally closed;
  • Maybe dirt and dust fell into the fuel system;
  • Check the condition of the spark plugs and the termination of the terminals to you;
  • Check whether gasoline flows out of the carburetor.
  • Maybe the air damper falls asleep in the carburetor.

If disorders have been found in the ignition system, the main reasons are below:

  • The feeling was formed on the candles;
  • The wrong gap on the candles is exhibited;
  • The foot button is sunk;
  • The tip of the spark plug has become unusable;
  • The gap has changed between the starter and the shoes, although the spark is not reached.

The next video check shows the order of the correct start of the engine:


In the forum, say the following about Motobloks Krotoff:


“An excellent device for its price. There are small nuances, but generally satisfied. The speeds are determined so that it is quite difficult to choose the right one, and either you have to run or hardly go after the walk tractor. With a weight of 110 kg, it becomes very difficult and even switched off regularly in light countries.

Advantages: Large selection of the problem, price

Disadvantages: The steering wheel is not taken aside (it is not very convenient to plow), there are only a few gearboxes, the assembly is not very, it seems crystal. “


“At first I thought that there were no differences between motor blocks, and above all, these are the properties. Oh how wrong I was. After I started it, it seemed to me that the engine worked loudly, but when I went into the field after entering the field, I found that it was still calm. He roars like a wounded lion on the battlefield. After an hour of work, the belt broke (although I used it far away from all strength). I had to change. The mills in the kit are plus, but they break very quickly – minus. The carburetor didn’t even serve the season, went to river. Fortunately, the guarantee was exchanged, but if you decide, take a look at another manufacturer.
