Note: The lawn mower comes with free-wheeling clutches
which make it easier to pull the lawn mower rearward. To
disengage the clutches, you may need to push the lawn
mower forward one inch (2.5 cm) or more after you
release the self-propel drive bail.
Adjusting the Cutting Height
You can adjust each wheel individually with a wheel
height adjustment lever. Cutting heights are 1 in.
(25 mm); 1-1/2 in. (38 mm); 2 in. (51 mm); 2-1/2 in. (64
mm); 3 in. (76 mm); and 3-1/2 in. (89 mm).
DANGER
POTENTIAL HAZARD
•
Adjusting the height-of-cut levers could bring
your hands into contact with a moving blade.
WHAT CAN HAPPEN
•
Contact with a rotating blade can cause serious
injury.
HOW TO AVOID THE HAZARD
•
Stop the engine and wait for all movement to
stop before adjusting the cutting height.
•
Do not put fingers under the housing when
adjusting the cutting height.
1. Pull the adjusting lever toward the wheel and move it

Operating Tips
•
Review the safety instructions and read this manual
carefully before operating the lawn mower.
•
Clear the area of sticks, stones, wire, branches, and
other debris that the lawn mower could pick up or the
blade could hit and throw objects.
•
Keep everyone, especially children and pets, away
from the area of operation.
•
Avoid striking trees, walls, curbs, or other solid
objects. Never deliberately mow over any object.
•
If the lawn mower strikes an object or starts to vibrate,
immediately stop the engine, disconnect the spark plug
wire, and examine the lawn mower for damage.
•
Maintain a sharp blade throughout the cutting season.
Periodically file down nicks on the blade.
•
Replace the blade when necessary with an original
Lawn-Boy replacement blade.
•
Mow only dry grass or leaves. Wet grass and leaves
tend to clump on the yard and may cause the lawn
mower to plug or the engine to stall.
