MOWINGTIPS
• Under certain c onditions, such
as very
tail grass, it may be necessaryto raise
the heightof cutto reducepushing
effort and to keep from overloadingthe
engine and leaving clumpsof grass
clippings. It may also be necessaryto
reducegroundspeed and/or runthe
lawn mower over the area a second
time.
• For extremelyheavy cuffing,reducethe
widthof cut by overlappingpreviously
cut path and mow slowly.
• For better grass baggingand most
cuttingconditions,the engine speed
shouldbe set in the fast position.
• Pores in clothgrass catcherscan
become filledwith dirt and dust with use
and catcherswillcollectlessgrass. To
preventthis, regularlyhose catcheroff
with water and let dry beforeusing.
• Keep top of engine aroundstarterclear
and clean of grassclippingsand 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. Clean UNDERSIDE OF
MOWER HOUSING after each use. See
"Cleaning" in 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 recutting 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 and the newly cut area will not be
exposed to the direct sun.
• 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 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 mulching, reduce your
width of cut,
mow slowly and raise
the rear of the lawn mower one wheel
adjuster setting higher than the front.
• 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
second cut, mow across or perpendicu-
lar 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.
