TIRES
Keep the pneumatic tires properly inflated. Over-
inflation will cause operator discomfort. Under-inflation
will cause short tire life.
Improperly inflated tires will also affect the leveling of
the mower deck and quality of cut.
Inflate the front and rear tires as shown in the following
table:
Tire Size
Front Tires
16 x 6.5–8
Rear Tires
23 x 9.5–12
Always ensure that the tire valve caps are in place and
tightened securely to prevent loss of air and to protect
the valve core and stem.
Do not overload the tractor tires by mounting
equipment on the tractor which exceeds the load
capacity of the size of the tires on the tractor.

WARNING
Do not mount a tire unless you have the proper
equipment. Do not inflate the tire above the

the tire and rim, which could result in serious
injury of death.
NOTE
After the first 10 hours of operation, check and
re-torque the rear wheel lug nuts (both sides) to
35 ft-lbs to make sure they are seated in the rim
