MULCHING
MOWING
TIPS
IMPORTANT:
For best performance,
keep mower housing
free of built-up
grass and trash_ See "CLEANING"
in the
Maintenance
section
of this manual.
° The special
mulching
blade will recut
the grass clippings
many times and
reduce them in size so that as they fall
onto the lawn they will disperse
into
the grass and not be noticed,
Also, the
mulched
grass will biodegrade
quickly
to
provide
nutrients
for the lawn,
Always
mulch with your highest
engine
(blade)
speed as this will provide
the best recut-
ting action of the blades.
• Avoid cutting
your lawn when it is wet.
Wet grass tends to form clumps
and
interferes
with the mulching
action°
The
best time to mow your lawn is the early
afternoon,
At this time the grass has
dried, yet the newly cut area will not be
exposed
to direct sunlight.
• For best resutts,
adiust the lawn mower
cutting
height so that the lawn mower
cuts off only the top one-third
of the
grass blades_
If the lawn is overgrown
it will be necessary
to raise the height of
cut to reduce
pushing
effort and to keep
from overloading
the engine and leaving
clumps
of mulched
grass,
For extremely
heavy grass, reduce
your width of cut
by overlapping
previously
cut path and
mow slowly,
• Certain
types of grass and grass
conditions
may require that an area be
mulched
a second
time to completely
hide the clippings.
When
doing a sec-
ond cut, mow across
(perpendicular)
to
the first cut path,
• Change
your cutting
pattern from week
to week.
Mow north to south one week
then change
to east to west the next
week.
This wilt help prevent
matting
and graining
of the lawn.
