MOWING TIPS
&
CAUTION: Do not use de-thatcher blade
attachments on your mower. Such at-
tachments are hazardous, will damage
yourmowerandcouldvoidyourwarranty.
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,
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
HOUSINGFREEOFBUILT-UPGRASS/TRASH.SEE"CLEANING"
IN THE MAINTENANCE 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 into the grass
and not be noticed, Also, the mulched grass will biode-
grade 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 iswet, 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, yet the newly cut area
will not be exposed to direct sunlight.
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 over-
grown 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,
MAXI_
FIG. 13
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 (perpendicular) to the first cut path.
Change your cutting pattern from week to week, Mow
north to south one week then change toeast to west the
next week, This will help prevent matting and graining
of the lawn,
