repeat pdmingsteps.
MOWINGTIPS
Under certain conditions,such as very
tall grass, it may be necessary to raise
the height of cutto reduce pushing
effortand to keep from ovedoedlng 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 grassmay not enter the grass
catcher. Reduce ground speed
(pushing speed) and/or run the lawn
mower over the area a second time.
If a trail of clippingsis left on the right
side of a rear discharge mower, mow in
a clockwise direction with a small
ovedap 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, 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 MOWINGTIPS
IMPORTANT: For bestperformance,
keep mower housing free of built-up
grass and trash. See =CLEANING" in the
Maintenance section of this manual.
The special mulching blade will racut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they willdisperse intothe
grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to providenutdents for the lawn.
Always mulch with your highest engine
(blade) speed as this will providethe
best recutting actionof the blades.
Avoid cuttingyour 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
eady afternoon, At this Umethe grass
has dded and the newly cut area will
not be exposed to the direct sun.
For best results, adjustthe lawn mower
cutting height sothat the lawn mower
cuts off only the top one-third ofthe
grass blades. If the lawn is overgrown
itwill be necessary to raise the height
ofcut to reduce pushingeffort end to
keep from overloading the engine and
leaving dumps of mulched grass. For
extremely heavy mulching, reduce your
width of cut by ovedapping 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 northto south one week
then change to east to west the next
week. This will help prevent matting
and graining of the lawn.
