摘要：
FIELD: agriculture.SUBSTANCE: set of soil tools to the harrows and cultivators with reduction drives with rotating blades in the main assembly contains a harrow frame in which on the frame racks in the bearing housings there are parallel arranged two drive shafts square in cross section. Shafts are dressed with a small gap and successively through an intermediate interval, the size of one working contour of the complete replacement blades, five gear drive large gears with oblique teeth on the outer diameter, which are fixed from the longitudinal displacement on the shaft by the fitted spacers, according to the size of the length of the intermediate intervals. Each intermediate interval on the first row of the drive shaft is overlapped by the same intermediate interval on the second row of the drive shaft with five geared drive large gears with oblique teeth on the outer diameter and with spacers in the same length. All large drive gears on the two drive shafts are contacted by oblique teeth in meshing with perpendicularly spaced gears small in diameter, fitted with their square central hole on the neck of the rotating axis in each bearing housing welded at the lower end of each frame, for each reduction assembly. At the lower end of the axis of each reduction assembly, on its mounting flange with a square lower projection in the center, a complete working replaceable blade is secured by six mounting screws from the bottom. Two drive shafts in parallel assembled with large gears connected in meshing with small gears on the axes with rotating blades in the reduction units, are driven into the rotary motion under the action of the main reduction shaft, mounted perpendicular to the center of the frame, with the two leading worm gears connected to the worm teeth of the two driven gears fixed with their central square hole to the drive shaft in the first row and the second driven gear to the drive shaft in the second row, and at the same time fixed from the longitudinal d
