MOWING TIPS
o Under certain conditions, such as very tall grass, itmay
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.
For extremely heavy cutting, reduce the width of cut
and raise the rear of the lawn mower housing one (t)
wheel adjuster setting higher than the front for better
discharge of grass.
° For better grass bagging and most cutting conditions,
the engine speed should be set in the high (,_)
position..
° When using a rear discharge lawn mower in moist,
heavy grass, clumps of cut grass may not enter the
grasscatcher. Reduce ground speed (pushing speed)
and/or run the lawn mowerover the area asecond time..
, Ifa trail of grass clippings is left on the right side of a rear
discharge lawn mower, mow in a clockwise direction
with a small overlap to collect the clippings on the next
pass,
° Pores incloth 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 fife..

MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH. SEE "CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL.
The special mulching blade will recut the grass clip-
pings many times and reduce them in size so that as
they fall onto the lawn they will disperse intothe 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 (See Fig. 13),. If the lawn is
overgrown itwill 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 andraise the rear of the lawn mower one
wheel adjuster setting higher than the front°
o Certain types of grass and grass conditions may re-
quire that an area be mulched a second time to com-
pEetelyhide the clippings° When doing a second cut,
mow across or perpendicular 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.
