7.18 TIRES ____________________________________________________________________
1. Keep tires properly inflated to prolong tire life. Check
inflation pressure while the tires are cool. Inspect
tread wear.
2. Check pressure once a month with an accurate, low
pressure tire gauge.
Front – 16-20 psi (110 -138 kPa)
Rear – 8-10 psi (55-69 kPa)
Casters – 20-25 psi (138-172 kPa)
3. When replacing front tires, the circumference varia-
tion from old tire to new tire must be within 2 in., (50
mm). The cutting height of front mower is directly
related to the radius of the front tires.
Improper mounting of a tire can
cause an explosion which can
result in serious injury.
Unless you have the proper training, tools and
experience, DO NOT attempt to mount a tire on a
rim. Improper mounting of a tire can produce an
explosion which may result in serious injury.
7.19 WHEEL MOUNTING PROCEDURE ____________________________________________
An improperly secured tractor
ready for adjustments can
cause serious injury or be fatal.
To prevent injury, lower implements to the
ground, disengage all drives, engage parking
brake, stop engine and remove key from ignition
switch before making any adjustments or
performing maintenance.
Make sure the tractor is parked on a solid and
level surface. Never work on a tractor that is
supported only by the jack. Always use jack
stands.
If only the front or rear of the tractor is raised,
place chocks in front of and behind the wheels
that are not raised.
1. Remove dirt, grease and oil from stud thread. Do not
lubricate threads.
2. Position wheel on hub and inspect to ensure full
contact between mounting surface of wheel and hub
or brake drum.
3. Finger tighten top nut, then rotate wheel so oppo-
site nut is at top and finger tighten. Finger tighten
remaining nuts in (criss-cross) order; always tighten
nuts in top position.
4. Check and retorque daily until proper torque is
maintained - Section 12.1.
7.20 TOWING __________________________________________________________________
1. The tow valve permits moving the tractor without
starting the engine. Do not exceed 2 mph (3.2 km/h)
while towing.
2. Tilt the operator’s seat forward for access to tow
valve. Turn knob 90° from normal to tow position.
3. After towing, be sure to return the knob back to its
normal operating position.
