conditions.

Adjust main frame height
with regards to the ground.

Bad ground contour
adaptation.

Incorrect main frame
setting.

Adjust main frame height
with regards to the ground.

Excessive ground speed.

Reduce ground speed.

Insufficient ground
pressure.

Reduce accumulator
pressure.

Obstruction of conditioning
rotor.

Insufficient rotor speed
(rotational frequency).

Check that the rotor drive
belts are correctly
tensioned.
