Setting Up Your Machine
Levelling – Front to Rear
Once coupled to the tractor, check the mower is cutting level from the front to the
rear of the machine. This is important to ensure each rotor will cut at the same height
(Fig. 3). The machine has adjustable tie bars that can be lengthened to lower the
front or shortened to raise the front of the machine by turning barrel nut (Fig. 2).
Once satisfied the mower is cutting level, tighten locking nuts.
Levelling – Wings LH & RH
With the machine in the working position and the wings folded down it may be
necessary to alter the height of the wing to ensure each rotor is cutting level.
There are several ways of adjusting the wing height on a Spearhead 460 mower.
These adjustments are necessary to compensate for wear and also variation of
tolerances. We recommend the wings are set 12
– 25mm (½ “ – 1) higher then the
centre chassis, to maintain a level cut.
2. Coarse adjustment is made via the serrated disc located on each wing axle,
move ball end rearwards to raise wing. Ensure the teeth fully engage. We
recommend lock-tight on the Allen bolt and torque of 500Nm.
1. Fine adjustment is made using the
tumbuckle located between the axles,
lengthen to lower the wing, shorten to
raise the wing.
(Note do not expose more than 25mm of
thread as the ball ends will foul in the
clevis when fully lowered)
Warning
The machine is set at t
he factory with the centre deck 1” (25mm) higher at
the front and the wings ½” (12mm) higher to the centre section, when
mounted on the tractor drawbar at 16” (400mm).
When operating over uneven ground it is recommended to raise the front
of the machine by adjusting the tie bars to prevent scalping or damage to
the blades.
