FIELD: agriculture.
SUBSTANCE: tillage device with a combined working body comprises a holder (1) and wings (3) of the tab (2). In the nose part of the tab (2) along the joint line of the oval wings (3) there is a through slot with a groove for the platform of the combined working body and a plug with a slot in the upper part. The working body is made in the form of a plate with two semi-ovals (10 and 11) of different heights with cutting edges and a common base, a platform rigidly fixed in the front part with protrusions for the groove and a cutout in the rear part. One part of the plate is the ripper, and the other is the slotter. The length of the base of the working body is twice the length of the platform. The plug is made in the form of a platform with upper and lower protrusions for the slot, the height of which is half the height of the platform. The length of the groove is equal to the length of the platform. The height of the slot and the height of the cutout are equal to the thickness of the wing (3). The nose parts (17) of the working body and the plug are made to copy the nose part (18) of the wings (3). Wings (3) of the tab (2) are installed at an angle to the horizontal plane 2…4°. The working width of the working body is 230…250 mm.
EFFECT: increased stability of the movement of the unit, the quality of tillage and the expansion of functionality.
