8.2.1 Cutting height
The desired cutting height is obtained directly by
adjusting the top link length. The height can be
adjusted between 30 and 60 mm (1.2’’ - 2.4’’)
depending on the tractors.
To obtain a different cutting height:
- Place the machine in transport 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.
If the tractor is fitted with a hydraulic top link, the
machine tilt angle can be adjusted in working
position.
The maximum cutting height (L1 = 60 mm (2.4’’))
is obtained when the discs are parallel to the
ground.
The minimum cutting height must not be below
(L2 = 30 mm (1.2’’)).
Too low a cutting height can lead to:
• Excessive disc and knife wear.
• Crop being contaminated by soil.
• Delay in regrowth.
