MOWING'rIPS
• Under certainconditions,such as very
tall grass, it may be necessaryto raise
the heightof cut to reduce pushing
effortand to keep from ovedoadingthe
engine and leaving clumpsof grass
clippings, tt may also be necessaryto
reduce groundspeed and/or run the
lawn mowerover the area a second
time.
• For extremelyheavy cutting,reducethe
widthof cut by overlappingpreviously
cut path and mow slowly.
• For better grass baggingand most
cuttingconditions, t he engine speed
shouldbe set in the fast position.
• When usinga rear dischargelawn
mower in moist,heavygrass, clumpsof
cut grass may not enter the grass
catcher. Reduce groundspeed
(pushingspeed) and/or run the lawn
mower over the area a secondtime.
• If a trailof clippingsis left on the right
side of a rear dischargemower,mow in
a clockwisedirectionwith a small
overlapto collectthe clippingson the
next pass.
• Pores in clothgrass catcherscan
becomefilled with dirt and dustwith use
and catcherswillcoltectless grass. To
preventthis, regularlyhose catcher off
with water and let dry before using.
• Keep top of engine aroundstarterclear
and clean of grass clippingsand chaff.
This will helpengine air flow and
extend engine life.
MULCHING
MOWINGTIPS
IMPORTANT:
For best performance,
keep mower housing free of built-up
grass and trash. 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 biodegrede 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 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
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.
