MOWING TIPS

to form clumps and interferes with the mulching action,
The best time to mow your lawn iSthe eady Afternoon,
At this time the grass has dded and the newly cut area
will notes exposed to the direct s0ri.
•
For best re,_utts, adjust the IeWli mower cu_Jng height
so that the lawn mowe_ cuts elf only the top one;third
of the grass blades (See EJg. 8), :If the lawn is
overgrown it will be necessary to'rais_the height of cut
to reduce pushing effort and to keep from byerloading
the engine and leaytngelumps of _ulPhedgrass,
For
extremely heavy mulching, red,Jce yoi4t width of cut,
mow slowly andTals_ the rea_"of the lawn mower one
wheel adjuster setting hlghe, r thari th=efront.
Certain types of gras_ ahd grass conditions may re;
quire that an area be mulched a rsecond time to
comp etely hide lhe clippings When :doing a second
cut, mew across or perpend!cular to the first cut path.
Change yourcutttng pattern from week to week, Mow
north to soulh one _eek then change tOeast to west the
next week. This will help prevent matt ng And grain ng
of the lawn.
•
Under certain conditions, such as very tallgrass, it may
be necessary to raise the height of c;ut to reduce
push ng effort and to keep from overloading the engine
and leav ng clumps of grass clippings.
•
For extremely heavy cutting, reduce the wtdih of cut
and raise the rear of the lawn mower housing one (1)
wh'eet adjL=stersetting higher than the front for better
discharge of grass.
•
For belier grass bagging and mbst Cutting _onditlons,
the engine speed should be set in the fast (.€_) position.
•
When using a rear discharge lawn mower in moist,
heavy grass, clumps of out grass may not enter the
grass catcher: Reduce ground speed (pushing speed)
a nd/or tun the lawn mows rover the area a second lime.,
