FIELD: agriculture.SUBSTANCE: working element of the cutter comprises a main shaft, a carrier with axes. The racks are movably mounted on the axes. One ends of the racks are made in the form of knives, and on the other their ends the rotating rollers are placed, rolling on the cam. The cam is fixed on the gear housing. The cam and the rollers have a conical shape. The leash is freely placed on the gear housing. One end of the leash is fixed by the handle, and the other end fits into the groove of the cam with the ability of longitudinal movement of the cam relative to the gear housing.EFFECT: reduction of energy consumption during cutting, reduction of spreading and excessive dispersion of soil, maintaining a constant angle of cutting of the blade and providing optimum conditions of cutting soil regardless of the forward velocity of the cutter.3 dwg |
