MOWING TIPS

• Under certain conditions, such as verytall

grass, itmay be necessary to raisethe

heightof cut toreduce pushing effort and to

keepfrom overloading the engine and

leavingdumps of grass cfippings..

- For extremely heavycutting, reducethe

width of cut and raisethe rear of thelawn

mower housing one (1)wheel adjuster

settinghigher than the front for better

dischargeof grass.

,, When using a rear discharge lawn mower in

moist,heavy grass,ctumps of cutgrass

may not enter the grasscatcher. Reduce

ground speed (pushing speed) and/orrun

the lawn mower over thearea a second

time,

•Ifa trailof grassclippingsis left onthe fight

side ofarear'discharge lawn mower, mow

ina clockwise direction with a smalloverlap

tocoltect the clippings on the next pass.

- Keep top of engine around starterclear and

dean of grassclippings and chaff.This will

help engine air flow and extend engine tire.

• Pores in cloth grass catcherscan become

titledwith dirt and dust wiLhuse and

catchers will collect lessgrass. To prevent

this, regularlyhose catchers offwith water'

and letdry before using

mower housing free of built-up grass and

trash. Clean underside of mower housing

after each use. See "Cleaning" in

CUSTOMER RESPONSIBILITIES section

of this manual.

grass clippings many times and reduce

them in size so that asthey fallonto the

lawnthey will disperse into the grassand

not be noticed. Also,the mulched grasswill

biodegrade quicklyto provide nutrientsfor

the lawn.Always mulch with yourhighest

engine (blade) speed asthiswiltprogidethe

best recuttingaction ofthe blades°

• Avoid cuttingyour lawn when it iswet.Wet

grasstends toform clumps and interferes

with the mulching action_The best time to

mow your lawn isthe early aftemoonoAt this

time the grass has dried andthe newly cut

area will not be exposed to the directsun

° For best results, adjustthe lawn mower

cutting height sothat the lawn mower cuts

off only the top one-thirdofthe grassblades.,

Ifthe lawn isovergrown it wiltbe necessary

to raisethe height ofcut to reducepushing

effort and to keep from overloading the

engine and leaving clumpsof mulched

grass. For extremely heavy mulching,

reduceyourwidth ofcut, mowslowly and

raisethe rear ofthe lawn mower one wheel

, Certain types of grassand grassconditions

may requirethat an area be mulched a

second time to completely hide the

clippings,When doinga second cut, mow
