ASSEMBLY

Initial Adjustments

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

1.Check free-wheel valves on both pump assemblies to make sure that the valves are closed. Tighten valves to 108-163 N•m (80-120 lb-ft).

2.Raise the rear of the machine until the drive wheels are off the ground. Support the machine with jackstands.

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.

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.

6.Move PTO clutch switch to on position; mower clutch should engage. Run blades for several minutes.

7.Move PTO clutch switch to off position and shut the engine off.

8.Check all belts for proper tension.

9.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.
