ASSEMBLY
Check Tire Pressure
1. Check tires for damage.
2. Check tire pressure with an accurate gauge.
3. Check that tires have equal pressure; add or remove air,
if necessary.
Level Mower Deck
Before operating the machine, level the mower deck.
Initial Adjustments
1. Check free-wheeling valves on both pump assemblies
to make sure that the valves are closed.
2. Raise the rear of the machine until the drive wheels are
off the ground. Support the machine with jackstands.
3. Start and run the engine until it reaches normal
operating temperature.
4. Move control levers to the forward position and observe
drive wheel rotation; the drive wheels should rotate in the
correct direction.
5. Move the control levers to the reverse position and
observe drive wheel rotation; the drive wheels should
rotate in the correct direction.
NOTE: Neutral position and transmission linkage
adjustments will needed to be recheck after several
hours of operation.
6. Release control levers; the levers should return to the
neutral position and wheel rotation should stop. If the
wheels do not stop, adjust the neutral adjustment knob on
each side of the seat.
7. Move PTO/clutch switch to on position; mower clutch
should engage. Run blades for several minutes.
8. Move PTO/clutch switch to off position and shut the
engine off.
9. Check all belts for proper tension.
10.Start the engine and test drive the machine in an open
area. Drive the machine forward; if the machine drifts to the
right or left, adjust the transmission control linkage.
PTO Clutch Run-in Procedure
1. Start and run the engine at half throttle.
2. Engage and disengage the PTO clutch five times (ten
seconds on, ten seconds off).
3. Move throttle lever to 3/4 throttle.
4. Engage and disengage the PTO clutch five times (ten
seconds on, ten seconds off).
c CAUTION: Avoid injury! Explosive separation
of tire and rim parts is possible when they are
serviced incorrectly:
• Do not inflate the tires above the
recommended pressure.
• Do not stand in front or over the tire
assembly when inflating. Use a clip-on chuck
and extension hose long enough to allow you
to stand to one side.
Tire Size Pressure
Front: 13 x 5.0 - 6 110-139 kPa (16-20 psi)
Rear: 23 x 9.5- 12 69-83 kPa (10-12 psi)
c CAUTION: Avoid injury! Clear area of
bystanders before performing this service
procedure.
c CAUTION: Avoid injury! Engine exhaust fumes
contain carbon monoxide and can cause
serious illness or death.
Move the vehicle to an outside area before
running the engine.
Do not run an engine in an enclosed area
without adequate ventilation.
• Connect a pipe extension to the engine
exhaust pipe to direct the exhaust fumes out of
the area.
• Allow fresh outside air into the work area to
clear the exhaust fumes out.
