2014 Toro Heavy Duty WPM – Cable Adjustment
Adjusting the Self-propel Drive
If the machine is new, does not self-propel, or it tends to creep forward, adjust the drive cable.
1. Move the machine outside and onto a paved surface near a solid wall to safely prevent the machine
from moving forward while the engine is running.
2. Position the machine with the front tires against the wall.
Note: Ensure that the area is well ventilated and clear of debris that could be thrown by the
machine.
3. Shift the transmission to third gear (machines with 3-speed transmissions only).
4. Start the engine; refer to Starting the Engine (in the Operators Manual).
5. Pull the self-propel-drive bar to the handle.
Note: The wheels should start to turn as the self-propel-drive bar just touches the handle.
6. Shut off the engine.
7. If you must adjust the machine, do the following:
• If the wheels do not spin when you engage the self-propel-drive bar, the traction belt is too
loose. Rotate the wheel-drive-control knob (Figure 1) clockwise 1 turn and repeat steps 4
through 6.
• If the wheels spin before you fully engage the self-propel-drive bar, the traction belt is too tight.
Rotate the wheel-drive-control knob (Figure 1) counterclockwise 1 turn and repeat steps 4
through 6.
8. For a new traction belt, rotate the drive cable adjustment knob clockwise 1 additional turn to allow
for the normal stretching of the belt during the break-in period.
Note: You can skip this step if you are adjusting a used belt.
