Using Your Lawn Mower
Thoroughly inspect the area where the equipment
is to be used. Remove all stones, sticks, wire,
bones, toys and other foreign objects which could
be tripped over or picked up and thrown by the
blade.
WARNING:
serious personal injury.
For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings, and
could cause you to slip and fall. New grass, thick
grass or wet grass may require a narrower cut.
When using side-discharge mower, the best
mowing pattern is one that allows the clippings to
discharge towards the uncut part of the lawn. This
permits recutting of the clippings to further pulverize
them. When cutting high weeds, discharge towards
cut portion, then recut at right angles to initial.
For a healthier lawn, always cut off one-third or less
of the total length of the grass. Lawn should be cut
in the fall as long as there is growth.
WARNING:
with your mower, stop the engine. Remove
wire from spark plug and de-energize starter,
thoroughly inspect the mower for any
damage, and repair the damage before
restarting
Excessive vibration of the mower during
operation is an indication of damage. The unit
should be promptly inspected and repaired.
Mulching
For effective mulching, do not cut wet grass
because it tends to stick to the underside of the
deck, preventing proper mulching of grass
clippings. New or thick grass may require a
narrower cut.
Adjust the ground speed according to the condition
of the lawn.
If mowing has been delayed and the grass has
been allowed to grow in excess of 4", do not mulch
the grass. Mow using the grass bag to reduce the
grass height to 3 1/4" maximum before mulching.
