Instructions for work
3. Adjustments in working position
Cutting height
The required height is set by means of the control box.
The height can be adjusted between 30 and
80 mm (
1.1’’ - 3.1’’ ) depending on the tractors.
To obtain a different cutting height:
- Lower the machine on the ground to remove weight
from the top link.
- Place central switch in position (a).
- Maintain switch (1) in position (b).
- Activate tractor hydraulic outlet associated with the
control box.
- Check cutting height.
-
The maximum cutting height (L1 = 80 mm (3.1’’))
is obtained when the discs are parallel to the
ground.
The minimum cutting height must not be below
(L2 = 30 mm (1.1’’)).
Too low a cutting height can lead to:
- Excessive disc and knife wear.
- Crop being contaminated by soil.
- Delay in regrowth .
