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.
Figure 7: 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 8 - centre).
Because of the pre-tensioning, this angle is
only reached while driving.
Figure 8: 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.
