24.7 Turning or changing the conveyor bars on the pre-compression roller
The pre-compression roller (1) is fitted with conveyor bars which have a smooth and a serrated
side. The conveyor bars can be attached in such a way that either the smooth or the serrated
side is used.
From experience the smooth side obtains the best results for grass operation and the serrated
side for maize operation.
NOTE
The conveyor bars must be changed if the wear is so great that the conveyor bars are no longer
higher than the crossbars on the pre-compression and feed roller.

safeguarding the machine".
• Remove the fastening bolts (3) from the conveyor bar (2).
• Turn the conveyor bar (2) and attach (tightening torque 35 Nm).
NOTE
Because of metal detection, only fastening materials made of anti-magnetic steel may be used.
The screws must not be tightened with an impact wrench because of the magnetising effect.
