Drive System
Maintenance

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.
4. Start the engine; refer to
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
clockwise 1 turn and repeat steps

•
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
counterclockwise 1 turn and repeat steps

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.

Blade Maintenance

Maintaining the Blade

Always mow with a sharp blade. A sharp blade cuts cleanly
and without tearing or shredding the grass blades.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug.
3. Close the fuel valve by moving the fuel-valve lever to
the left (Figure
4. Drain the gasoline from the fuel tank.
5. Tip the machine onto its right side (air cleaner up) as
shown in Figure
12).

Carefully examine the blade for sharpness and wear, especially
where the flat and the curved parts meet
Because sand and abrasive material can wear away the metal
that connects the flat and curved parts of the blade, check
the blade before using the machine. If you notice a slot or
wear (Figure 27B and
