Abstract (en)
The device has a soil erosion device and a control device (1) with two pairs of control flaps supported at a framework (12) and two guide wheels (5). The flaps and a servo-jack align the tool in a desired position when the tool is deviated. Force and an adjustment path of the jack are distributed on the flaps. The wheels are pivoted at a pivot arm such that the digging device is shifted laterally during the formation of slots.
