MOWINGTIPS
• Under certain conditions,such as very
tall grass,it may be necessary to raise
the height of cut to reduce pushing
effortand to keep from overloading the
engine 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 previously
cut path and mow slowly.
• For better grass bagging and most
cuttingconditions, the engine speed
should be set in the fast position.
• Pores in cloth grass catchers can
become filted with dirt and dust with
use and catchers will collect less grass.
To prevent this, regulady 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.
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 forthe lawn.
Always mulch with your highest engine
(blade) speed as this will provide the
best recottingaction ofthe blades.
• Avoid cuttingyour lawn when it is wet.
Wet grass tends to form clumps and
interfereswith the mulching action.
The best time to mow yourlawn isthe
early afternoon. At this time the grass
has dded and the newly cut area will
not be exposed to the direct sun.
• For best results, adjustthe lawn mower
cuttingheight 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 pushingeffort and to
keep from overloading the engine and
leaving clumps of mulched grass. For
extremely heavy mulching, reduce your
width of cut by overlapping previously
cut path and mow slowly.
• Certain types of grass and grass
conditionsmay require that an area be
mulched a second time to completely
hide the clippings. When doing a
second cut, mow across or perpendicu-
lar tothe 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,
