Important: Always adjust the Number of Spacers below Caster Hub to correspond to the Axle
Position as shown in table to obtain proper "rake" (blades should always be level to the ground
or tipped slightly down at the front).
Adjusting the Axle Position
Desired cutting height range can be obtained by
adjusting the rear axle and placing caster spacers
above or below the caster arm (see Figure 9 and
Figure 10 along with the Cutting Height Adjustment
Chart).
To adjust rear axle:
1.
Stop the machine and move the drive levers to
the neutral lock position.
2.
Disengage the PTO.
3.
Raise the rear of the machine up onto jack stands
and remove the drive wheels.
4.
Loosen but do not remove the top two bolts
on each hydraulic motor mounting bracket (see
Figure 9).
5.
Remove the bottom sets of hardware for each
bracket.
6.
Reposition the mounting bracket to the desired
height and reinstall the bottom hardware.
7.
Tighten all hardware and remount drive wheels.
8.
Remove jack.
9.
Adjust wheel drive and brake linkages as
required (see Brake and Wheel Drive Linkage
Adjustment section).

Note: The axle positions are in 1/2 inch (1.3 cm)
increments and the large caster spacers are 1/2
inch (1.3 cm) thick. Therefore, by adjusting the
same number of 1/2 inch (1.3 cm) caster spacers as
axle hole positions the blades will retain the same
front-to-back tip (rake).
