Levelling plate closed to an excessive extent.
Ground speed too low.
Rotor speed too fast (versions with gearbox).
Levelling plate open to an excessive extent.
Ground speed too high.
Soil too wet.
Low rotor speed (versions with gearbox).
Soil too wet.
Levelling plate closed to an excessive extent.
Ground speed too high.
The cultivator blades retain the worked soil.
Very tall grass and/or excessively long plant cuttings.

Remedies
Set the third point hitch parallel to the lower lifting links.
Limit the lifting travel.
If the fault persists, disengage the PTO as the machine starts to lift.
Lengthen or shorten the third point hitch so that the upper surface of
the rotary cultivator is parallel to the ground worked (the PTO connec-
tions of the tractor and rotary cultivator must be parallel).
Ensure that the rotary cultivator remains stable by means of the rods
of the lower lift links.
Reduce the work depth by adjusting the rotary cultivator's depth skids.
Replace the complete set of cultivator blades to ensure that the rotor
is stable.
Reduce the speed of the gearbox.
Change the position of the levelling plate.
Reduce the work depth by adjusting the rotary cultivator's depth skids.
Raise the levelling plate to make the soil shift more easily.
Reduce the speed of the gearbox.
Raise the levelling plate to prevent the clods from being broken up too
much.
Increase the ground speed.
Reduce the speed of the gearbox.
Lower the levelling plate to break up the soil clods to a greater extent.
Reduce the ground speed.
Do not work soil that is too wet.
Increase the speed of the gearbox.
Do not work soil that is too wet.
Raise the levelling plate.
Reduce the ground speed.
Reduce the number of cultivator blades from 6 to 4 for each rotor flange.
Do not work when the grass is too high or the plant cuttings are very
long. If necessary, remove the clogged plants from the supports at the
sides of the rotor to prevent them from overheating.
