Checking the Tire Pressure

Service Interval: Before each use or daily
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
Do not under-inflate.
performance.
Checking the Torque of the Wheel Nuts
or Bolts
Service Interval: After the first 10 hours
Every 200 hours
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
2. Check/fill plug
castor forks, add or remove an equal number of spacers
from the castor forks, and secure the rear chain to the
desired hole.
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.
1. Castor wheel
2. Tensioning cap
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 inch spacers (refer to the chart
