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 clip pings 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 bio de grade
quick ly to provide nu tri ents for the lawn.
Always mulch with your highest engine
(blade) speed as this will provide the
best recutting action of the blades.
• Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
in ter feres with the mulch ing 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 results, adjust 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 over grown
it will be nec es sary to raise the height
of cut to reduce pushing effort and to
keep from over load ing the engine and
leaving clumps of mulched grass. For
ex tremely heavy grass, reduce your
width of cut by overlapping previously
cut path and mow slowly.
• Certain types of grass and grass
con di tions may re quire that an area be
mulched a second time to com pletely
hide the clip pings. 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 will help prevent matting
and graining of the lawn.
MOWING TIPS
CAUTION:
Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• Under certain conditions, such as very
tall grass, it may be necessary to raise
the height of cut to reduce pushing
effort and to keep from over load ing the
en gine and leaving clumps of grass
clippings. It may also be necessary to
reduce ground speed and/or run the
lawn mower over the area a second
time.
• For extremely heavy cutting, reduce the
width of cut by overlapping pre vi ous ly
cut path and mow slowly.
• For side discharge lawn mowers, cut-
ting in a counter-clockwise di rec tion,
starting at the outside of the area to
be cut, spreads grass clip pings more
evenly and puts less load on the en-
gine. To keep clip pings off of walkways,
flower beds, etc., make the first cuts in
a clock wise direction.
MAX 1 / 3
• Pores in cloth grass catchers can be-
come filled with dirt and dust with use
and catchers will collect less grass. To
prevent this, regularly hose catcher off
with water and let dry before using.
• Keep top of engine around starter clear
and clean of grass clippings and chaff.
This will help engine air flow and extend
engine life.
