Operator use and adjustment
WARNING!
Before use ensure that all operators have read and thoroughly understood all the safety
procedures. For further information refer to the relevant sections of this manual.
6.4.1
Machine Settings and 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 are capable of supporting
the machine mass indicated in Section 1.4 Machine general specification.
6.4.2
Setting the cutting height using skids
The cutting height of the pasture topper can be adjusted to cut at heights from 50mm to 175mm. This is
achieved by moving the bolt-on skids at each side of the machine.
WARNING!
Use assistance when removing the skids. They are heavy and may cause injury.
Figure 6.2
To adjust the cutting height:
Raise the machine on the tractor lift arms and support it on safety supports.
6.4.2.1
Remove the nuts, bolts and washers securing the skid to the machine.
6.4.2.2
Reposition the skid to the new desired position. Use the cutting height decals on the side of the
6.4.2.3
machine. See Figure 6.2 as a guide.
Fit and tighten all nuts and bolts securely, see
‘Torque Settings’, page 43.
6.4.2.4
Repeat the process for the other skid, ensuring that both skids are at the same height setting.
6.4.2.5
Raise the machine on the lift arms and remove the safety supports.
6.4.2.6
Re-try the machine and re-adjust the skid height if the cutting height is still not acceptable.
WARNING!
When raising the mower to transport height ensure there is clearance between the mower and the
driveline.
DAMAGE CAN BE CAUSED IF THE DECK CONTACTS THE DRIVELINE
.
WARNING!
Avoid injury. Stop the tractor engine, remove ignition key and allow blades to stop rotating before
making adjustments.
IMPORTANT
Avoid very low cutting heights; striking the ground with the blades can send damaging shock
loads into the gearboxes and drive system which will also cause premature blade wear.
