OPERATION
MOWING TIPS

Make sure the lawn is clear of stones, sticks, wires, and
other objects that could damage the lawn mower blades
or engine. Do not mow over property stakes or other
metal posts. Such objects could damage the blade or be
accidentally thrown by the mower in any direction and
cause serious personal injury to the operator and others.

For a healthy lawn, always cut off one-third or less of the
total length of the grass.


When cutting heavy grass, reduce walking speed to allow
for more effective cutting and a proper discharge of the
clippings.

Do not cut wet grass. It will stick to the underside of the
deck and prevent proper bagging or mulching of grass
clippings.

New or thick grass may require a narrower cut or a higher
cutting height.

Clean the underside of the mower deck after each use
to remove grass clippings, leaves, dirt, and any other
accumulated debris.
NOTE:
To clean, follow instructions in
Washing the Un-
derside of the Mower Deck
later in this manual.
SLOPE OPERATION
See Figure 12.
WARNING:
Slopes are a major factor related to slip and fall accidents
that can result in severe injury. Operation on slopes
requires extra caution. If you feel uneasy on a slope, do
not mow it. For your safety, do not attempt to mow slopes
greater than 15 degrees.

Mow across the face of slopes, not up and down. Exercise
extreme caution when changing direction on slopes.
 Watch for holes, ruts, rocks, hidden objects, or bumps
which can cause you to slip or trip. Tall grass can hide
obstacles. Remove all objects such as rocks, tree limbs,
etc., which could be tripped over or thrown by the blade.

Always be sure of your footing. A slip and fall can cause
serious personal injury. If you feel you are losing your bal-
ance, release the upper blade control lever immediately.
 Do not mow near drop-offs, ditches, or embankments;
you could lose your footing or balance.
