MOWINGTIPS

•Under certain conditions,such as very

tall grass, it may be necessary to raise

the height ofcut to reduce pushing

effortand to keep from ovedoading the

engine and leavingclumps of grass

clippings. It may also be necessary to

reduce ground speed and/or run the

lawn mower over the area a second

time.

•Forextremely heavy cutting,reduce the

width of cut by overlapping previously

cut path and mow slowly.

•For better grass baggingand most

cuttingconditions,the engine speed

shouldbe set in the fast position.

• When using a rear discharge lawn

mower in moist, heavy grass, clumps of

cut grass may not enterthe grass

catcher. Reduce ground speed

(pushingspeed) and/or run the lawn

mowerover the area a secondtime.

•If a trailof clippingsisleft on the right

side ofa rear dischargemower, mow in

a clockwisedirectionwith a small

ovedap to collect the clippingson the

next pass.

•Pores in cloth grass catcherscan

become filled with dirtand dust with use

and catchers witlcollactless grass. To

prevent this, regularlyhose catcher off

with water and let dry before using.

• Keep top of enginearound starterclear

and clean of grass clippingsand chaff.

This will helpengine air flow and

extend engine lite.

MULCHINGMOWINGTtPS

IMPORTANT: For best performance,keep

mower housingfree of built-upgrass and

trash. Clean UNDERSIDE OF MOWER
