MOWINGTIPS
• 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
(pushing
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-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 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 eady
attemoon. 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 mu}ching,
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.
