Machine Adjustments
WARNING!
Before working on any piece of attached machinery, ensure that the tractor engine is turned off
and the starter key removed to prevent anyone else from starting the tractor while it is being worked on.
WARNING!
Always park on a suitable firm, level surface with the parking brake applied, and ensure the
machine has come to a complete stop before commencing work.
WARNING!
Before attempting to access the underside of the machine, ensure it is adequately and safely
supported. Do not rely on the tractor’s hydraulics. Use safety supports that have a minimum Safe Working
Load (SWL) of 1.5 tonnes.

Cutting height adjustment
The cutting height of the pasture topper can be adjusted to cut at heights from 30mm to 150mm. This is achieved by
moving the bolt-on skids at each side of the machine; see Figure 5.1.
WARNING!
Use assistance when removing the skids. They are heavy and may cause injury.
Figure 5.1
To adjust the cutting height:
Raise the machine on the tractor lift arms and support it on safety supports.
Remove the nuts, bolts and washers securing the skid to the machine.
Reposition the skid to the new desired position; use the cutting height decals on the side of the machine
(arrowed) as a guide.
Fit and tighten all nuts and bolts securely; see Section 6.14.
Repeat the process for the other skid, ensuring that both skids are at the same height setting.
Raise the machine on the lift arms and remove the safety supports.
Re-try the machine and re-adjust the skid height if the cutting height is still not acceptable.
