RESULT IN SERIOUS INJURY OR DEATH.

II. SLOPE OPERATION

Slopes are a major factor related to loss-of-control and tip over

accidents, which can result in severe injury or death. All slopes

require extra caution. If you feel uneasy on it, do not mow it.

DO:

• Mowupanddownslopes,not across.

• Removeobstaclessuchasrocks,treelimbs,etc.

• Watchforholes,ruts,orbumps.Uneventerraincouldoverturnthe

machine. Tall grass can hide obstacles.

• Useslowspeed.Choosealowgearsothatyouwillnothavetostop

or shift while on the slope.

• Follow the tractor manufacturer’s recommendations for wheel

weights or counterweights to improve stability.

• Keepallmovementontheslopesslow and gradual. Do not make

sudden changes in speed or direction.

• Avoidstartingorstoppingonaslope.Iftireslosetraction,disengage

the blades and proceed slowly straight down the slope.

DO NOT:

• Donotturnonslopesunlessnecessary,andthen,turnslowlyand

gradually downhill, if possible.

• Donotmowneardrop-offs,ditches,orembankments.Themower

could suddenly turn over if a wheel is over the edge of a cliff or

ditch, or if an edge caves in.

• Donotmowonwetgrass.Reducedtractioncouldcausesliding.

Ill. CHILDREN

Tragic accidents can occur if the operator is not alert to the presence

of children. Children are often attracted to the machine and the mowing

activity. Never assume that children will remain where you last saw

them.

• Keepchildrenoutofthemowingareaandunderthewatchfulcare

of another responsible adult.

• Bealertandturnmachineoffifchildrenenterthearea.

• Before and when backing, look behind and down for small

children.

• Nevercarrychildren.Theymayfalloffandbeseriouslyinjuredor

interfere with safe machine operation.

• Neverallowchildrentooperatethemachine.

• Useextracarewhenapproachingblindcorners,shrubs,trees,or

other objects that may obscure vision.

I. GENERAL OPERATION

• Read,understand,andfollowallinstructionsinthemanualandon

the machine before starting.

• Read this operator’s manual carefully. Become familiar with the

controls and know how to operate your mower properly.

• Onlyallowresponsibleadults,whoarefamiliarwiththeinstructions,

to operate the machine.

• Clear the area of objects such as rocks,toys, wire, etc., which

could be picked up and thrown by the blade.

• Be sure the area is clear of other people before mowing. Stop

machine if anyone enters the area.

• Nevercarrypassengers.

• Donotmowinreverseunlessabsolutelynecessary.Alwayslook

down and behind before and while backing.

• Slowdownbeforeturning.

• Neverleavearunningmachineunattended.Alwaysturnoffblades,

and stop engine.

• Turnoffbladeswhennotmowing.

• Mowonlyindaylightorgoodarticiallight.

• Donotoperatethemachinewhileundertheinuenceofalcohol

or drugs.

• Watchfortrafcwhenoperatingnearorcrossingroadways.

• Use extra care when loading or unloading the machine into a

trailer or truck.

• Do not attempt to operate your tractor or mower when not in

drivers seat.

• Disengagepowertomower,stopenginewhentransportingornot

in use.

• Exercisespecialcarewhenmowingaroundxedobjectsinorder

to prevent the blades from striking them. Never deliberately run

tractor or mower onto or over any foreign object.

• Usemoweronlyasthemanufacturerintendedandasdescribed

in this manual.

• Donotoperatemowerifithasbeendroppedordamagedinany

manner. Always have damage repaired before using your mower.

• Alwayswearsafetyglassesoreyeshieldswhenstartingandwhile

using your mower.

• Dressproperly.Donotoperatemowerwhenbarefootorwearing

open sandals. Wear only solid shoes with good traction when

mowing.

• Always make cutting height adjustments before starting your

mower. New attempt to do this while the engine is running.

• Keepyoureyesandmindonyourmowerandtheareabeingcut.

• Donotletotherinterestsdistractyou.

• Before cleaning, inspecting, or repairing your mower, stop the

engine and make absolutely sure the blade and all moving parts

have stopped. Then disconnect the spark plug wire and keep it

away from the spark plug to prevent accidental starting.

• Do not operate your mower if it vibrates abnormally. Excessive

vibration is an indication of damage or unbalanced blades. Stop

the engine, safety check for the cause of the vibration and repair

as required.

• Neveroperateyourmowerwithoutproperguards,plates,orother

This mower has been designed to run offset from the

center of the tow vehicle. This allows the operator to drive

along side high brush with the tow vehicle while cutting

down the brush beside him. The adjustable hitch gives

you three offset cutting positions plus straight behind for

narrow paths.

MODEL 45-0362

The adjustable hitch of this mower can be set in seven

positionsincludingstraightandoffsetsof9",17"and23"

REPAIR PARTS

Your rotary mower has been produced with components

designedforyourunit.AlthoughstandardV-belts,

bearings, blades, pulleys, etc. may look like parts used on

your rotary mower, while similar in appearance many are

of a different construction and could in some cases cause

a malfunction in the operation of the machine.

For continued satisfactory performance use only repair

parts supplied by the manufacturer. See the dealer where

the mower was purchased for factory replacement parts.
