made by a plough body,
• at the distance of 1 - 3 cm from the skid,

• at the minimum distance of 5 cm before
the edge of the first ridge, the mould

board and the share,
• without interfering with the gauge wheel.
All rolling coulters should be uniformly
aligned.

not drop down,
• loosen the operating depth adjustment bolt,
• turn the frame on the rack to the desired
position,
• tighten the bolt.
The distance from the skid is set:
• by loosening bolts A and B,
• turning A bolt on it axis in the longitudinal
hole of B bolt to the desired position,
• tightening A and B bolts.
