CULTIVATOR WITH TWO ROWS OF DISCS ARRANGED IN MOVING DIRECTION Russian patent published in 2015 - IPC A01B21/08 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to disc harrows. The disc harrow comprises two rows of disks parallel and placed transversely to the direction of movement. The discs of the front row are inclined outwardly backwards to the sides of the agricultural machine and on the dividing line parallel to the direction of motion of the agricultural machine, forming the first area of changing the direction of the discs inclination. The discs of the rear row are inclined in the inner direction backwards from the sides of the machine on the dividing line to form a second area of changing the direction of the discs inclination. The discs of the front row are arranged with the ability to throw the soil from the first area of changing the direction of the discs inclination outwardly towards the sides of the agricultural machine. The discs of the second row are arranged with the ability to throw the soil from the sides of the agricultural machine inside toward the second area of changing the direction of the discs inclination. The dividing line with the first area and the second area of changing the direction of the discs inclination is located at a distance from the midline of the agricultural machine in the direction transverse to the direction of motion and on line with the track of one wheel of the towing means.

EFFECT: constructive solution is aimed to exclude the possibility of formation of the ridge or skip in processing.
