There is a pulley on the output shaft of the motor reducer.

Ignition – electronic contactless magneto "MB-1", as on the chainsaws "Druzhba" and "Ural" widespread in the USSR. Spark plug "A-17V". However, even with the "A-11" spark plug, the motor cultivator engine operates stably, carbon formation on the spark plug does not form, glow ignition is not observed. The average fuel consumption (for the "Krot-2" motor block) is 0.96 l / kW per hour.

Transmission
The engine of the Krot walk-behind tractor is made in a single block with a single-stage gear reducer (motor transmission). The Krot-2 motor cultivators also have a reverse gear. The motor reducer is lubricated with M-8B1 motor oil (It is also permissible to use TAD-17 transmission oil (SAE 85W90).

The torque is transmitted to the pulley of the main reducer via a V-belt drive.

The clutch of the walk-behind tractor is constantly disengaged, it is engaged by a handle, like on a motorcycle or moped. When the clutch is engaged, the V-belt is tensioned, its slippage on the pulley is eliminated, and torque is transmitted. The main gearbox is two-stage (chain and a pair of gears). Lubrication - transmission oil "TAD-17" (SAE 85W90).

Technical features of the "Mole" walk-behind oman mobile database for different types of work
• For pre-sowing soil cultivation:
Contrary to popular belief, the MK-1 Krot walk-behind tractor does not plow the soil, but cultivates it (which is reflected in its name: motor cultivator). That is, it loosens and levels its top layer.

The soil cutters are fixed on the output shafts of the gearbox; the transport wheels are raised, a coulter is attached to the bracket, which acts as a brake and regulates the depth of processing. The cutters are the working element and, at the same time, the driving force of the Krot motor cultivator.

The walk-behind tractor is equipped with a set of cutters (two internal and two external - respectively: "right" and "left"). When developing complex (virgin and fallow) lands, it is recommended to use only internal cutters.

On relatively light (garden and vegetable) soils, it is permissible to additionally use a third set of cutters (purchased separately). With six cutters, despite the increased load, the Krot motor cultivator works well, and even more stably, without trying to "dig" into the soil.


But the MK-1 Krot walk-behind tractor will not be able to handle eight cutters. More precisely, it will handle them, but with great difficulty – with overload and overheating of the engine and the risk of breakage of the handles. Therefore, it is not advisable to overdo it with cutters. You can try to plow the land; mounted plows for walk-behind tractors are available for sale. The more powerful Krot-2 is capable of more or less satisfactorily coping with this task.
