9.12 TIRES ___________________________________________________________________
Keep the tires correctly inflated to increase tire life. Inspect the tread wear.
Check the tire pressure each day, while the tires are cool. Use an accurate low-pressure tire gauge.
Keep the rear tires inflated to 8-10 psi (0.55-0.69 BAR). If the optional pneumatic-front tires are installed, keep the front
tires inflated to 12-15 psi (0.83-1.03 BAR).
9.13 WHEEL MOUNTING PROCEDURE ____________________________________________
Remove dirt, grease and oil from the stud threads. Do not lubricate threads.
Put the wheel on the hub. Inspect the wheel to make sure of full contact between surface of wheel and hub.
Tighten all hardware with your fingers, then torque hardware in a criss-cross order. When possible, tighten nuts in the
top position.
Check and torque hardware each day until torque is kept at 65-75 ft.lb. (88-102 Nm).
CAUTION
DO NOT try to put a tire on a rim unless you have the correct training, tools and experience. Incorrect mounting can
cause an explosion which can cause injury.
WARNING
Make sure the mower is parked on a solid and level surface. Never work on a mower that is supported only by the
jack. Always use jack stands.
If only the front or behind the mower is lifted, put the chocks in front of and behind the wheels that are not lifted.
