8.3 Adjustments in working position
8.3.1 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:
- 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 equipped with a hydraulic top link,
the machine pitch angle can be adjusted during
work.
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.
