OPERATION
Always use the clutch pedal when shifting gears. The lawn tractor
pulls away from a complete stop in any gear. This means you can
start off from a complete stop when any gear is selected.
Keep the shift lever in the MOWING range (gears 1-3) when actually
mowing grass. The TRANSPORT range (gears 4-5) should only be
used for transporting the lawn tractor (when the PTO clutch lever is
OFF) and is not recommended for mowing.
SHIFTING FROM A FORWARD GEAR TO ANOTHER FORWARD GEAR
1. Push the clutch pedal all the way down.
2. Move the shift lever to the desired gear position.
3. Gently release the clutch pedal.
4. You don't need to bring the lawn tractor to a full stop if shifting
from one forward gear to another.
SHIFTING BETWEEN ANY FORWARD GEAR AND REVERSE
1. Press the clutch pedal all the way down, then press the brake
pedal all the way down to stop the lawn tractor.
2. Move the shift lever to the desired gear.
3. Gently release the brake pedal, then the clutch pedal.
Hydrostatic Transmission Model
The hydrostatic transmission in your lawn tractor offers you an
infinitely variable range of speeds. This means you only need to move
the shift lever to change the forward ground speed and to move in
reverse.
Keep the shift lever in the MOWING range when actually mowing
grass. The TRANSPORT range should only be used for transporting
the lawn tractor (when the PTO clutch lever is OFF) and is not
recommended for mowing.
