MOWING TIPS
• 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 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
cutting conditions, the engine speed
should be set in the fast position.
• When using a rear discharge lawn
mower in moist, heavy grass, clumps of
cut grass may not enter the grass
catcher. Reduce ground speed (push-
ing speed) and/or run the lawn mower
over the area a second time.
• If a trail of clippings is left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
overlap to collect the clippings on the
next pass.
• Pores in cloth grass catchers can
become 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.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-upgrass and
trash. See "Cleaning" in Maintenance section
ofthis manual.
• The special mulching blade will recut the
grass clippingsmany 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 aftemocn. 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
cuttingheightso that the lawn mower cuts
off onlythe top one-thirdofthe grass blades.
Ifthe lawn is overgrown itwill be necessary
to raisethe height ofcut to reduce pushing
effortand to keep from overioadingthe
engine and leaving clumpsof mulched
grass. For extremely heavy mulching,
reduce yourwidth ofcut by overlapping
previouslycutpath and mow slowly.
• Certain types of grassand grass cond_ions
may requirethat an area be mulched a
second time to completely hide the
clippings. When doing a second cut,mow
across or perpendicular to the firstcut path.
• Change your curlingpattern from weak to
weak, Mow northto southone week then
change to east to west the next week. This
will help prevent mattingand grainingofthe
lawn.
