SAFE MOWING GUIDE

While mowing, if you hit a foreign object, stop

the engine. Remove the spark plug wire. Care-

fully and thoroughly inspect the mower for

damage. Make necessary repairs before re-

starting. If the unit starts to vibrate abnormally,

stop the engine immediately and check for the

cause. Vibration is generally a warning of

trouble. Keep all nuts, bolts, and screws tight.
The blade is the most dangerous part of the

mower and also the most important part in ob-

taining a nice lawn appearance. Check the

blade and the blade  mounting hardware fre-

quently. Keep it tight. If the blade hits a solid

object, check it thoroughly for deformation or

cracks and replace if damaged. For safety,re-

place the blade every two years. A sharp blade

reduces the work load on the engine and cuts

grass more cleanly, for a better looking cut with

less work. The blade is always close to the out-

side of the mower housing. For best trimming

on side discharge mowers, cut with the left

side of the housing toward the area that needs

trimming.
A useful accessory for your mower is a grass

catcher. There are grass catchers available for

most models. For best performance and safe-

ty, be sure the grass catcher is approved for

use with your mower. Assemble as directed

and follow operating and safety instructions

with the catcher and in the Instruction Book.
Before mounting, checking or emptying the

grass catcher, always turn the engine off. Re-

member to check the grass catcher before

each use for cracks, wear, or deterioration. Re-

place any part that is damaged with the man-

ufacturer’s recommended replacement part

before using the grass catcher again. 

Proper cutting technique is important if you

want your lawn to look good. Avoid the tempta-

tion to cut grass too short. Cutting grass too

short can kill the plant, cause grass to turn yel-

low, or make the lawn look brown and thatchy.

Use the lower cutting heights in cool months

when the grass is lush. Use the higher cutting

heights in extremely dry periods. Cutting with

a dull blade or low engine speed bruises,

shreds, and can uproot some grass making

the lawn look dull and brown a few days after

cutting. Always put the throttle control, if

equipped, in FAST position when mowing and

bagging. When bagging, slower ground speed

will provide the best results.
Change the mowing pattern slightly each time

you cut. If you always cut the same way, the

grass will develop a “set” and clippings will ac-

cumulate more heavily in some areas more

than in others causing grass to get thinner in

those areas. Do not service your mower over

the grass. Spilled oil and gas can kill the grass.

In tall grass or very heavy grass, do not try to

cut it all at once. Raise the height of cut on the

first cutting and lower it for the next cutting the

same day or within a few days. Another way is

to cut only part of the width of the mower and

adjust your ground speed (not the engine) to

move more slowly so the mower can clear it-

self as it moves forward. 

When cutting with a walk behind mower, al-

ways push the unit. Do not pull it. Pushing the

unit keeps the operator behind the mower in

the “operator’s zone” for better control. Push-

ing the unit also gives you a chance to see ex-

actly where and what you are mowing. There

will be times while you are mowing that you will

have to pull the mower backwards (such as

when the front of the mower has come up

against a wall or fence). If you must back up,

make sure your feet are in the clear. Stand well

back from the mower, plant your feet firmly with

each step and back up being careful to look be-

hind you. Resume normal mowing as soon as

possible.
If your unit is self-propelled, remember that

the drive mechanism is not designed to do all

the work, but the unit can move without your

help. Always keep your hands on the handle

near the controls when the engine is running.

Remember too that the self-propelled mecha-

nism can be dangerous. Keep hands and feet

away from belts and chains. Always turn off the

engine before attempting to remove anything

that becomes entangled in the  self-propelled

system.
Remember, your mower is a useful tool, but it

can be dangerous. Follow the instructions in

this Instruction Book. Use the mower properly

and carefully and it will give you many hours of

trouble free, accident free operations.
