Adjust the fertiliser discs to prevent them
¾
from touching the ground during drilling. They
would be abraded and then wear one-sided.
Adjust the fertiliser coulter, when needed, and
¾
also when not used that the coulter discs turn
in the soil.
Maintenance
Bearings are oil-filled and therefore mainte-
¾
nance free.
Check the discs regularly for clearance, leak
¾
tightness, wear and free rotation.
B
Check the condition of the rubber mounting
¾
and replace if the rubbers lose their tension.
If the coulter discs are worn, slightly turn the

fertiliser pipes upward to prevent them from
being abraded.
