6.14.8 Stone protection
Every individual share body is attached to a tilting frame (1) that allows it to move.
The share body is kept at the set share depth by the cylinder of the share depth
adjustment (2). When the share hits a stone in the ground, the share body can move
upwards and thereby overcome the obstacle. This displaces the hydraulic fluid from
the stone protection cylinder into a pressure reservoir (3). Once the obstacle has been
overcome, the oil from the pressure reservoir presses the share back into the ground.
