Check Tire Pressure, Level Mower Deck

ASSEMBLY

Check Tire Pressure

cCAUTION: 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.

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.

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)

Level Mower Deck

Before operating the machine, level the mower deck.

Initial Adjustments

cCAUTION: Avoid injury! Clear area of bystanders before performing this service procedure.

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.

cCAUTION: 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.

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).
