The Krot motor block can also be used to pump water from open water bodies and tanks. For this purpose, a pumping unit connected to the engine by a V-belt transmission is installed on its frame. The V-belt transmission is removed from the traction gearbox. The MNU-2 pumping unit used for this work is naturally purchased separately.
The "Mole" can also be of some use for transporting loads weighing up to 200 kg on a small-sized "TM-200" trolley with a rotary coupling device. Rubberized wheels are mounted on the output oman mobile database of the gearbox.
The "Mole" is relatively easy to handle, does not require a large storage space, and its small weight and dimensions simplify its transportation.
Description of the design of the "Mole" walk-behind tractor
The frame, consisting of two half-frames, is bolted to the gearbox. The tubular handles for controlling the motor cultivator and the bracket for installing additional attachments are located at the rear of the motor block. The handles contain controls for engine speed and clutch (on the Krot-2 modification, also for engaging reverse gear).
The output shafts of the Krot gearbox are fitted with soil cutters, 320 mm in diameter, for plowing the soil, weeding or wheels (for working with a hiller (or a plow, as well as for operating a cultivator with a cart). An internal combustion engine is attached to the frame, connected by a V-belt transmission to the input shaft of the gearbox.
The fuel tank is located on top. The cultivator is rolled using lifting wheels, but they must be raised or removed during operation.
The Krot walk-behind tractor operates on the following principle. Rotating motion is transmitted via a V-belt to the gearbox and then to the two output shafts. After the clutch is engaged, the belt is pulled, setting the gearbox shaft in motion. During combined idle operation, the clutch is disengaged.
The gearbox shaft, equipped with milling cutters - rotors with special knives, rotates, cutting off layers of soil, simultaneously crushing and mixing it. Thus, with progressive movements, the "Mole" makes its way forward.
