Setting the cutting height
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.
Undo the side skid attachment bolts and using the cut height decal reposition the side skids at the desired cut
height, see Figure 5.4.
WARNING:
Take care to ensure that both skids are set at the same height.
Figure 5.4
If your machine is equipped with folding wings or, decks mounted on deployment arms, make sure that each
deck is level and parallel to the ground. Failure to ‘set’ the machine for level cutting will result in an uneven cut
height.

PTO driveshaft installation
The PTO driveshaft attaches between the tractor and the machine gearbox to transfer the power required to the run
and operate the machine
– it is important to achieve the correct shaft length to avoid risk of it ‘bottoming out’ when
raising or lowering the machine.
Due to many different makes and sizes of tractor to which mowers may be fitted, a nominal length PTO shaft is
supplied with the machine. In some cases, the nominal PTO shaft supplied will be too long and will have to be
shortened, see below.
IMPORTANT:
The recommended minimum engagement of the PTO is 150mm in the working position. This
measurement must be considered when shortening the PTO shaft. (See Figure 5.6)
