Checking the Tire Pressure

The tires are over-inflated for shipping. Therefore,
release some of the air to reduce the pressure. The
correct air pressure in the front and rear tires is
25-30 psi (172-207 kPa).
Important: Maintain even pressure in all
tires to ensure a good quality-of-cut and proper
machine performance. Do not under-inflate.
Checking the Torque of the Wheel
Nuts or Bolts
Failure to maintain proper torque of the
wheel nuts could result in failure or loss of
wheel and may result in personal injury.
Torque the front wheel nuts and rear
bolts to 85-100 ft-lb (115-136 N⋅m) after
1-4 hours of operation and again after 10
hours of operation. Torque every 200 hours
thereafter.
Adjusting the Height-of-Cut
Center Cutting Unit
The height-of-cut is adjustable from 1 to 5 inches
(25 to 127 mm) in 1/2 inch (13 mm) increments.
To adjust the height-of-cut on the front cutting
unit, position the castor wheel axles in the upper
or lower holes of the castor forks, add or remove
an equal number of spacers from the castor forks,
and secure the rear chain to the desired hole.
2. Check/ll plug
1. Start the engine and raise the cutting units so
that the height-of-cut can be changed. Stop
the engine and remove the key after the cutting
unit is raised.
2. Position the castor wheel axles in the same
holes in all castor forks. Refer to the following
chart to determine the correct holes for the
setting.

3. Spacers
Note: When operating in 2-1/2 inch (64
mm) height of cut or higher, the axle bolt
must be installed in the lower castor fork hole
to prevent grass buildup between the wheel
and the fork. When operating in height of
cuts lower than 2-1/2 inches (64 mm) and
grass buildup is detected, reverse the machines
direction to pull any clippings away from the
wheel/fork area.
3. Remove the tensioning cap from the spindle
shaft (Figure 14) and slide the spindle out of the
castor arm. Put the 2 shims (1/8 inch [3 mm])
onto the spindle shaft as they were originally
installed. These shims are required to achieve
a level across the entire width of the cutting
units. Slide the appropriate number of 1/2
