CAUTION!
The tines may be pre-tensioned only when the Tined Weeder Pro is
unfolded.
Figure 8
During the folding procedure, first the outer side frame is folded by 180° onto the
inner frame, which is then folded up by 90°.
If the implement is unfolded into working position, the hydraulic control units
and/or the double-acting hydraulic control units must be moved to the "N - neutral"
position.
CAUTION!
To achieve a transport width of less than 3 m, the feeler
wheels on the first side frame must be completely moved
up in the feeler wheel bracket.

PLEASE NOTE!
When uncoupling the hydraulic hoses for the tine pre-
tensioning under pressure, first close the stop tap, and
only then unplug the hydraulic hoses. By doing so, the
tines remain in the desired position, even when the
harrow is parked.

WORKING POSITION AND SETTING THE WORKING DEPTH
The harrow intensity is set with the pre-tensioning of the spring pack. The pre-setting
is made hydraulically and comfortably from the tractor seat. On the scale (see Figure
10), the driver can read the level that is currently set. Here, the springs are not pre-
tensioned at positions -3 to 0. Pre-tensioning begins at 0, and the full pre-tension is
reached at position 6. At position -3, the tines are folded up, which means that the
tines are in transport position.
The working speed has a significant effect on the intensity of harrowing. The normal
speed range is between 1 and 12 km/h, depending on the crop sensitivity and growth
stage.
The feeler wheels can be moved on the frame to the desired track width. The
clearance and the tine angle can be adjusted using the pattern of holes in the feeler
wheels.
