Note: Do not shift speeds while squeezing the control bar
against the handle in the Run/Drive position; this can
damage the transmission. Move the control bar to the
Run/Shift position (Fig. 10) when you change the ground
speed.
Note: You can vary the ground speed by increasing or
decreasing the distance between the control bar and the
handle. Lower the control bar to decrease the ground
speed when you are making a turn or if the lawn mower is
moving too fast for you. If you lower the control bar too
far, the lawn mower stops self-propelling. Squeeze the
control bar closer to the handle to increase the ground
speed. When you hold the control bar tight against the
handle, the lawn mower self-propels at the maximum

ground speed. Move the ground speed control to the
Neutral position when you use the lawn mower for
trimming or whenever you leave the lawn mower.
Using the Discharge Tunnel
Plug
1. Stop the engine and wait for all moving parts to stop.
2. Insert the discharge tunnel plug; refer to Installing the
Discharge Tunnel Plug on page 6.
3. To remove the plug, move the discharge door handle
rearward and lift up the spring clip on the bottom of
the plug. When the plug is unlocked, pull it out of the
discharge tunnel.
Note: When grass is thick and lush, clippings may collect
on and around the discharge tunnel plug. This may make
removing the plug difficult. Clean the plug thoroughly
after each use.

Adjusting the Cutting Height

Each wheel is adjusted individually with a wheel height
adjustment lever. Cutting heights are 3/4 inch (1.9 cm),
1-1/4 inches (3.2 cm), 1-3/4 inches (4.4 cm), 2-1/4 inches
(5.7 cm), 2-3/4 inches (7.0 cm), and 3-1/4 inches (8.3 cm).
Danger
Adjusting the cutting height levers could bring
your hands into contact with a moving blade and
result in serious injury.
Stop the engine and wait for all moving parts to
stop before adjusting the cutting height.
Do not put your fingers under the housing when
adjusting the cutting height.
1. Pull the wheel height adjustment lever toward the
wheel (Fig. 11) and move it to the desired setting.
