HYDRAULIC TINE ADJUSTMENT
The tines are adjusted with multiple hydraulic cylinders connected in parallel. This allows the tine pre-
tension to be changed while driving.
All of the hydraulic cylinders (Figure 13) are connected by an oil circuit. Adjustments are made using a
double-acting control unit and the flow divider on the centre frame (Figure 14).

ADDITIONAL ADJUSTMENT OPTIONS FOR GROUND
ADAPTATION
The slot in the cylinder working point on the side frame further
improves the ground adaptation of the Tined Weeder Pro. If the
laterally bolted, folding locking plates are installed, the upward
ground adaptation of the side frame is fully available, but the
downward ground adaptation is limited. This has the advantage
that the harrow sags less, which is helpful when turning. If the
plates are removed, the ground adaptation is fully available in
both directions.

ADJUSTING THE FEELER WHEEL TRACK
To set the desired track width for the feeler wheels, the nuts on the U
brackets of the feeler wheel brackets must be loosened. Then the
feeler wheel bracket and the section are pushed into the desired
position and the nuts are retightened.
Figure 16
CAUTION!
The nuts on the U brackets of all feeler wheel brackets on the
Tined Weeder Pro may only be tightened to a maximum of 25
Nm to avoid damage to the U bracket.
