clockwise (closed position). Tighten valve to 9-14 N•m (80- 120 lb-in.).

6. Lock the park brake.

Transporting Machine

c CAUTION: Avoid injury! Use caution when loading or unloading machine into a trailer or truck.

IMPORTANT: Avoid damage! Transmission damage may occur if the machine is moved or towed incorrectly:

•Move unit by hand only.

•Do not use another vehicle to move unit.

•Do not tow unit.

Use a heavy-duty trailer to transport your machine. Trailer must have signs and lights required by law.

1.Raise the mower deck lift lever to the transport position.

2.Drive machine on trailer.

3.Stop engine and lock the park brake.

4.Remove key.

5.Fasten machine to trailer with heavy-duty straps, chains or cables. Both front and rear straps must be directed down and outward from machine.

Picture Note: Left pump shown.

2.Turn free-wheel valve (A) on both pumps one full turn counterclockwise (open position).

3.Unlock the park brake.

4.Push machine to desired location. Due to hydraulic system drag, machine will move slowly.

5.Turn free-wheel valve (A) on both pumps one full turn

Mowing Tips

•Mow grass with throttle lever in the full-throttle position.

•Cut grass when it is dry.

•Keep mower deck and discharge chute clean.

•Mow with sharp blades.

•Properly level mower deck for a smooth cut.

•Mow grass high and often.

•Use a travel speed that fits the conditions:

•Mow tall or wet grass twice. Cut grass at half desired height; then cut at desired height.

•Travel slow when mowing tall, thick or wet grass.

•Avoid damaging grass by slipping or skidding machine drive wheels. Practice smooth control lever movements.

•When performing sharp turns, do not allow inside machine drive wheel to stop and twist on grass.
