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
15 x 6–6
Rear Tires
20 x 9–8
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.
