CORRECTOR-DISTRIBUTOR OF THE COUPLING WEIGHT OF THE HARROWING MACHINE-TRACTOR UNIT Russian patent published in 2022 - IPC A01B23/00 A01B21/08 A01B63/11 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to the field of agricultural engineering. The device contains a flexible cable power connection, mounting brackets. The device is made in the form of a kit containing a flexible cable power connection (1), fixed with ends in mounting brackets (2), fixed on the lower central part of the side beams (3) of the central frame (4) of the harrow (5), and a system of block rollers (6, 7, 8). At the same time, the cable power connection (1) passes through two supporting single block-rollers (6) installed in the lower part of the front half-frame (9) of the tractor (10) on the support bracket (11), the double block-roller (7) is fixed in lower part of the rear semi-frame (12) of the tractor (10) in the place of horizontal displacement of the semi-frames in the turn, the tractor hitch (10), two supporting single block rollers (8) installed on the front part of the central frame (4) of the harrow (5).

EFFECT: increase in traction and coupling properties and stabilization of the running system of the harrowing machine-tractor unit in motion, reduction in weight, metal consumption of the structure of the aggregated agricultural machine, improvement in the quality and depth of tillage with a heavy disc harrow, ease of operation of the unit.
