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 50 mm (1.1" - 1.9").
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.
-
Before leaving the tractor or before
adjusting, maintaining or repairing the
machine, disengage the PTO drive, turn off
the engine, remove ignition key and wait until
all moving parts have come to a complete
stop and apply park brake.
The maximum cutting height L1 = 50 mm (1.9’’)
is obtained when the disks are parallel to the
ground.
The minimum 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
