The higher the feeler wheels are moved up in the frame, the smaller
the distance between the frame and the ground and the steeper the
position of the tine ends relative to the ground.
To set all of the feeler wheels, including those at the rear, to the same
height, the same number of holes must be visible above the bracket on
all of the feeler wheels.
Figure 11: Working position
PLEASE NOTE!
When the feeler wheels are moved further down, the clearance is increased and the tine angle
becomes steeper, and therefore more aggressive. The tine pressure remains the same.
PLEASE NOTE!
Ideally, there should almost be a right angle (90° -
100°) between the wearing end of the tine and the
soil (see Figure 12 - centre). Because of the pre-
tensioning, this angle is only reached while driving.
Figure 12: An angle of 90° - 100° is ideal
All of the tine rows should penetrate the soil at the same depth (working depth), i.e. the frame must run
parallel to the ground.
To achieve this, the extension of the top link must also be adjusted. The parallelism of the frame to the
ground can be read on the spirit level on the centre frame, provided that you are on a horizontal plane.
CAUTION!
Only set the harrow with pre-tensioned springs on the ground when the vehicle is already in
motion. If the harrow is set down on the ground too rapidly at a standstill, there can be damage
to the implement.
CAUTION!
When the harrow is lowered, do not allow it to push or roll back with the tractor; otherwise, the
tines and bearing points can be damaged.
CAUTION!
After longer stretches of road transport or standstill, there can be differences in the pre-tension
in the hoses due to a change in temperature of the oil. For this reason, pre-tension the tines
completely and then loosen them again completely two times. Then you can set the desired pre-
tension (e.g. Level 2). This has to be done when the implement is lowered onto the ground.
CAUTION!
Driving in curves is not permitted. If there is no other option, these curves must be driven in a
very large radius.
CAUTION!
The working speed may not exceed 12 km/h.
