Materialiter Mr-3-4 (motor cultivator, 3-I model, 4-rotor) is a result of long searches conducted by young inventors. The final version consists of engine, from chainsaws “Friendship” with a homemade step-down gear, the Whole mechanism is mounted on a frame supported on two rubber wheels of the kart. Handles are two section of water pipe; the spacer between them fastened pivotally with the front wheel which functions as a regulator of penetration.
In the transport position, the front part of motorycles, i.e. the gearbox and underneath the knife raised. Knives represent a U-shaped bracket and positioned so that upon rotation come into adjacent, mutually cleaning each other.
