MOWING TIPS

• Formostcuttingconditionsand better

baggingperformance,the engine speed

shouldbe setinthe fast position.

•Undar certaincenditJorts,such as when

mowingverytallgrass,raisethe mower

heighton the firstcutto reducepushing

effort,to avoid overheatingthe engine, and

to avoidleavingdumps of grassclippings.

Make the secondcuttothe desiredheight.

•Forexb'emelyheavy cutting,reducethe

w_h of cut.

•Pores inclothgrasscatcherscan become

filledwithdirtand dustwithuseand the

catcherwillcollectlessgrass. To prevent

this, regularlyhosecatcheroffwithwater

and letdrybeforeuse.

MULCHING MOWING TIPS

IMPORTANT: Forbestperformance,keep

mowerhousingfree of built-upgrassand

bash.See "Cleaning" in MAINTENANCE

sectionof thismanual.

•The specialmulchingblade will recutthe

grass clippingsmany timesand reduce

them insize sothat astheyfallontothe

lawnthey will disperseintothe grassand

notbe noticed,Also,the mulchedgrass

willbiodegradequicklyto providenubients

for the lawn. Alwaysmulchwithyour

highestengine (blade)speed as this will

providethe bestrecuttingactionof the

blades.

• Avoid cutting your lawn when it is wet. Wet

grass tends to form dumps and interferes

with the mulching action. The best time to

mow your lawn is the early afternoon. At

this time the grass has driedand the newly

cutarea willnotbe exposedtothe direct

SUn.

•Forbestresults,adjustthe lawn mower

cuttingheight so thatthe lawnmower cuts

offonlythe topone-thirdof the grass

blades. If the lawn isovergrownitwillbe

necessaryto raisethe heightofcutto

reducepushingeffortand to keepfrom

overloadingthe engine and leaving

clumpsof mulchedgrass.Forextremely

heavy mulching,reduceyour width of cut

by overlappingpreviouslycut pa_ _md

moo slowly.

•Certaintypesof grassand grass cond_ons

may requirethatan area be mulcheda

secondtime to completelyhidethe

clippings. When doingasecond cut,mow

acrossor perpendicularto the tirstcutpath.

•Change yourcuttingpattemfmmweekto

week. Mow northto southone weak than

change toeast to westthe nextweak. This

willhelp prevent matting and grainingof

the lawn.
