Instructions for work
2. Adjustments in working position
 Cutting height
The desired cutting height is obtained directly by
adjusting the top link length. The height can be adjusted
between 30 and 80 mm (1.1’’ - 3.1’’) depending on the
tractors.
To obtain a different cutting height:
- Place the machine in working position.
- Lower the machine on the ground to remove weight
from the top link.
- Modify the top link length to alter the machine tilt
angle.
- Check cutting height.

Reduced or increased ground pressure
Increase spring tension (1):
- when working on slopes.
- When the headstock is in the maximum right offset
position.
Adjustment
- Tighten nut (2) to tension spring and increase the
outer skid ground pressure.
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 .
