FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT iN SERIOUS INJURY OR DEATH. I. GENERALOPERATION

• Read, understand, and follow all instructions in the manual and on the machine before starting.

• Only allowresponsible adults, who are familiar withthe

instructions,tooperate the machine.

• Clear the area of objectssuch as rocks, toys,wire, etc.,

which could be picked up and thrown by the blade.

• Be surethe areais clear ofother people before mowing,

Stop machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary. Always lookdown and behind before and while backing.

• Be aware ofthe mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.

• Slow downbefore turning.

• Never leavea runningmachine unattended. Alwaystum offblades, setparkingbrake, stop engine, and remove keys before dismounting.

• Turn offblades when not mowing.

• Stop engine before removing grass catcher or unclog- ging chute.

• Mow only in daylight or good artificial light.

• Do not operate the machine while underthe influence of alcohol or drugs.

• Watch for traffic when operating near or crossing road-

ways.

• Use extra care when loading or unloading the machine

into a trailer or truck.

• Data indicates that operators, age 60 years and above,

are involved in a large percentage of riding mower-

related injuries. These operators should evaluate their ability to operate the dding mower safely enough to protect themselves and others from serious injury.

II. SLOPE OPERATION

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

tipover accidents, whichcan result insevere injuryordeath. All slopes require extra caution. If you cannot back up the slope or 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.

• Useslowspeed. Choose a low gear so that you willnot

have to stop or shiftwhile on the slope.

• Followthe manufacturer's recommendations for wheel

weights orcounterweights to improve stability.

• Use extra care with grass catchers or other attach-

ments. These can change the stability of the machine.

• Keepallmovementontheslopess/owandgradual. 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

straightdown the slope,

DO NOT:

• Do not turnon slopes unless necessary, and then,turn

slowlyand gradually downhill, if possible.

• Do not mow near drop-ofts, ditches, orembankments.

The mower couldsuddenlyturn over ifa wheel isoverthe edge of a cliff or ditch, or if an edge caves in,

• Donotmowonwetgrass.Reducedtractioncouldcause sliding.

• Do not try to stabilize the machine by putting your foot on the ground.

• Do not use grass catcher on steep slopes.

IlL CHILDREN Tragic accidents can occur if the operator is notalert tothe

presence of children. Children are often attracted to the

machine and the mowing activity. Never assume that

children willremain where you last saw them.

• Keep children out of the mowing area and under the watchfulcare ofanother responsible adult.

• Be alert and turn machine off ifchildren enter the area.

• Before and when backing, look behind and down for

small children.

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

injuredorinterfere with safe machine operation.

• Never allow children to operate the machine.

• Useextracare when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

IV. SERVICE

• Use extra care in handling gasoline and other fuels.

They are flammable and vapors are explosive.

not smoke.

Never refuel the machine indoors.

Never store the machine or fuel container inside

where there is an open flame, such as awater heater.

• Never run a machine inside a closed area.

• Keep nutsand bolts, especially blade attachment bolts, tight and keep equipment in good condition.

• Never tamper with safety devices. Check their proper

operationregularly.

° Keep machine free of grass, leaves, or other debris

build-up. Clean oilor fuel spillage. Allow machine tocool before storing.

• Stop and inspect the equipment if you stdke an object. Repair. if necessary, before restarting.

• Never make adjustments or repairs with the engine running.

• Grass catcher components are subject to wear, dam- age, and detedoration, which could expose moving pads or allow objects to be thrown. Frequently check compo- nents and replace with manufacturer's recommended

pads, when necessary.

• Mower bledes are sharp and can cut. Wrap theblade(s)

or wear gloves, and use extra caution when servicing

them.

• Check brake operation frequently. Adjust and service as required.

• Keep children out of the mowing area and under the watchful care of another responsible adult.

• Be alert and turn machine offifchildren enter the area.

• Before and when backing, lookbehind and down for

small children.

• Mow up and down slopes (15° Max), 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 lowgear sothatyou willnot

have to stop or shift while on the slope.

• Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly

straight down the slope.

• If machine stopswhile going uphill, disengage blades, shift into reverse and back down slowly.

• Do nottu m onslopes unless necessary, and then, turn slowly and gradually downhill, ifpossible.

Look for this symbol to point out important safety precautions. It means CAUTION!!!

BECOME ALERT!!! YOUR SAFETY IS IN- VOLVED,

CAUTION: Do not coast down a hill in neutral, you may lose control of the trac-

tor.

CAUTION: Tow only the attachments that are recommended by and comply with specifications of the manufacturer of your tractor. Use common sense

when towing. Operate only at the lowest

possible speed when on a slope. Too heavy of a load, while on a slope, is dangerous. Tires can lose traction with tne ground and cause you to lose control of your tractor.

• Turn ignition key to "OFF" position and remove key.

Always remove key when leaving tractor to prevent

unauthorized use.

• Never use choke to stop engine. IMPORTANT: LEAVING THE IGNITION SWITCH INANY POSITION OTHER THAN "OFF" WILL CAUSE THE BATTERY TO BE DISCHARGED, (DEAD).

NOTE: Under certain conditionswhentractorisstanding idle with the engine running, hot engine exhaust gases may cause "browning" of grass. To eliminate this possibility, always stop engine when stoppingtractor ongrass areas.

CAUTION: Always stop tractor com- pletely, as described above, before leav- ing the operator's position; to empty grass catcher, etc.

TO USE THROTTLE CONTROL (See Fig. 6)

Always operate engine at full throttle.

• Operating engine at less than full throttle reduces the

battery charging rate.

• Fullthrottle offers the best bagging and mower perfor- mance.

TO MOVE FORWARD AND BACKWARD (See

Fig. 6)

The direction and speed of movement is controlledbythe gearshift lever.

• Start tractor with clutch/brake pedal deoressed and

gearshift lever in neutral (N) position.

• Move gearshift lever to desired position.

• Slowly release clutch/brake pedal to start movement.

IMPORTANT: BRING TRACTOR TO ACOMPLETE STOP BEFORE SHIFTING OR CHANGING GEARS. FAILURE TO DO SO WILL SHORTEN THE USEFUL LIFE OF YOUR

TO ADJUST MOWER CUTTING HEIGHT (See Fig. 6)

The cuttingheight iscontrolled byturningtheheight adjust- ment knob indesired direction.

• Turn knob clockwise ( _ ) to raisecuttingheight.

• Turn knob counterclockwise (P_) to lower cutting

height.

The cutting height range is approximately 1-1/2" to 4". The

heights are measured from the groundtothe blade tipwith

the engine not running. These heightsare approximateand

may vary depending upon soil conditions, height of grass

and types of grass being mowed.

• The average lawn should becuttoapproximately 2-1/2

inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate growth.

• For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height.

TO OPERATE MOWER (See Fig. 7) Your tractoris equipped with an operator presence sensing

switch. Any attempt by the operator to leave the seat with

the engine running and the attachment clutchengaged will shut off the engine.

BEFORE STARTING THE ENGINE

CHECK ENGINE OIL LEVEL (See Fig. 14)

• The engine inyourtractor has been shipped, from the

factory, already filled with summer weight oil.

• Check engine oilwith tractor on level ground.

• Remove oil fill cap/dipstick and wipe clean, reinsert the

dipstick and screw cap tight, wait for a few seconds,

remove and read oil level. If necessary, add oil until

"FULL" mark on dipstick is reached. Do not overfill.

• For cold weather operation you should change oil for

easier starting (See "OIL VISCOSITY CHART" in the

Customer Responsibilities section of this manual).

• To change engine oil, see the Customer Responsibilities

section in this manual.

ADD GASOLINE

• Fill fuel tank. Use fresh, clean, regular unleaded

gasolinewith a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline• Purchase fuel in quantities that can be used within 30 days to assure fuel freshness,

IMPORTANT: WHEN OPERATING IN TEMPERATURES

BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE

GASOLINE TO HELP iNSURE GOOD COLD WEATHER

STARTING.

WARNING: Experienceindicatesthat alcoholblended fuels

(called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids

during storage. Acidic gas can damage the fuel system of

an engine while in storage. To avoid engine problems, the

fuel system should beemptied before storage of30 days or

longer. Drain thegas tank, startthe engine and let itrun until

the fuel lines and carburetor are empty. Use fresh fuel next

season. See Storage Instructionsfor additional information. Never use engine or carburetor cleaner products inthefuel tank or permanent damage may occur.

• Move throttle control to choke (1\1)position.

NOTE: Before starting, read the warm and cold starting proceduresbelow.

• Insert key into ignition and turn key clockwise to "START' position and release key as soon as engine

starts. Do not run starter continuously for more than fifteen seconds per minute. Ifthe engine does not start after several attempts, move throttle control to fast position,wait a few minutes and try again. Ifengine still does not start, move the throttle control back to the choke (1\1)position and retry.

WARM WEATHER STARTING (50° F and above)

• When engine starts, move thethrottlecontrol to the fast position.

• The attachments and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above.

COLD WEATHER STARTING ( 50° F and below)

• When engine starts, allow engine to run with thethrottle control in the choke (N) position until the engine runs roughly, then move throttle control to fast position. This

may require an engine warm-up period from several

seconds to several minutes, depending on the tempera-

ture.

• The attachments can also be used during the engine

warm-upperiod.

NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 F) the carburetorfuel mixture may need tobe adjusted for best engine performance. See 'q'O ADJUST CARBURETOR" in the Service and Adjustments

section of this manual.

MOWING TIPS

• Mower should be properly leveled for best mowing performance. See "TO LEVEL MOWER HOUSING" in

the Service and Adjustments section of this manual.

• The lefthand side ofmower shouldbe usedfortrimming.

• Driveso that clippings are discharged ontothe area that

has been cut. Have the cut area to the right of the machine. This will result in a more even distribution of clippingsand more uniform cutting.

• When mowing large areas, startbyturningtothe rightso thatclippings willdischarge away from shrubs, fences, driveways, etc. After one ortwo rounds, mow in the opposite direction making left handturns untilfinished (See Fig. 9).

If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dded clip- pings. Make first cut relatively high; the second to the

desired height.

• Do not mow grass when itis wet. Wet grass will plug

mowerand leave undesirableclumps. Allowgrassto dry before mowing.

• Always operate engine at full throttle when mowing to assure better mowing performance and proper dis- charge ofmaterial. Regulate greundspeed by selecting a low enough gear to give the mower cutting perfor- mance as well as the quality of cut desired.

• When operating attachments, select a ground speed that willsuittheterrain and givebest performance ofthe attachment being used.

FIG. 9

MULCHING MOWING TIPS

IMPORTANT: FOR BEST PERFORMANCE, KEEP MOWER HOUSING FREE OF BUILT-UP GRASS AND TRASH.

CLEAN AFTER EACH USE.

• The specialmulchingblade willrecutthe grass clippings

many times and reduce them in size sothat as they fall ontothe lawnthey willdisperseintothe grassandnot be noticed. Also, the mulched grass will biodegrade quickly toprovide nutrientsfor the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades.

° Avoid cuttingyour lawn when itiswet. Wet grass tends

toform clumpsand interferes withthe mulching action. The best time to mow your lawn isthe early afternoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun.

• For best results,adjust the mower cuttingheight so that

the mower cuts off only the top one-third of the grass blades (See Fig. 10). For extremely heavy mulching,

reduce your widthof cuton each pass andmow slowly.

• Certain types of grass and grassconditionsmay require

that an area be mulched a second time to completely

hide the clippings. When doing a second cut, mow across or perpendicular to the first cut path.

• Change your cutting pattern from week to week. Mow

northtosouth one week thenchange toeast towest the next week. This willhelp prevent matting and graining ofthe lawn.

TO SHARPEN BLADE (See Fig. 12)

NOTE: We donotrecommend sharpening blade - butifyou do, be sure the blade isbalanced.

Care should be taken to keep the blade balanced. An unbalanced blade will cause excessive vibration and even-

tual damage to mower and engine.

• The blade can be sharpened with a file or on agdnding wheel. Do not attempt to sharpen while on the mower.

• To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.)

NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.

• Slide blade on to an unthreaded portion of the steel bolt

or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal

position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced.
