CORRECT ENGINE OPERATION

,&CAUTION fA Before starting the engine, become familiar

with all controls. Read this owner's manual thoroughly. Always check the engine and trans· mission oil level before starting.

.& WARNING &. Car. Ihould be tolcen to avoid inhaling ex-

haust gases as they contain carbon monoxide gao which i. colorless and odorless. Carbon monoxide il a dangerous gas that can cause unconsciousness and is potentially lethal.

Do not run the engine in confined areas such as a garage since exhaust fumes contain deadly carbon monoxide.

STARTING THE ENGINE (Automatic Transmission Models)

Because of a built-in safety interlock system, your new Wheel Horse will not start until the clutch pedal is depressed and the PTO (power take-off) is dis­engaged.

To start the engine depress the "brake" (return to neutral) pedal and di�ngoge the PTO. Raise the throttle control lever about half way up. Raise 'he choke control all the woy up_

Turn the ignition key clockwise until the starter engages. When the engine starts. release the key. The switch is spring looded ond will return to the run position automatically.

When starting the engine during cold weather, engage the parking broke. When the parking brake is engaged. the transmission is disconnected from the engine and reduces the load on the starter. After the engine storts and has run for a short while, disengage the parking brake and allow the transmission to worm vp before attempting to operate the tractor.

If th. engine fail. to slort after 30 second. of continuous cron.lng, turn the key to the "OFF" position and allaw the .tarler motor 10 cool. Check for c:ause of hard starting, consuh "Troubl.shooting Guide" found an poge 18.

STARTING THE ENGINE (S-Speed Transmission Models)

Because of a built-in sofety interock system, your new Wheel Horse will not stort untii the clutch pedal is depressed and the PTO (power take·off) is dis· engaged.

To start the engine depress the clutch pedal and disengage the PTO. Raise The throttle control lever about half way up. Raise the choke conrrel all the way up.

&CAUTICN & Always place the transmmion gear mift 'ever

in the neutral position before attempting to staft the engine.

ELECTRIC START MODELS

Turn the ignition key clockwi!te until the storter engages. When the engine !ttarts, release the key. The switch is spring loaded and will return to the run position automatically.

If the engine fail, to start after 30 seconds of continuous cranking, tUrn the key to the "OfF" position and allow the starter motor to cool. Check for cause of hard starting, consult "Troubleshooting Guide" found on page 18.

RECOIL START MODELS

Turn the ignition key '0 the "RUN" position. Grab the recoil storting handle and pull quickly. Return the handle slowly. When the engine storts, slowly return the choke lever to the "RUN" position. tf the engine foils to start after three or favr puJls, return the choke to it's "RUN" position.

STOPPING THE ENGINE

To stop the engine, return the throttle lever to the "SLOW" position and turn the ignition key to the "OFf" position. If the engine has been working hard. or the engine is "hot", allow the engine to idfe a short time before turning the key off. This practice wilt help to "cool" your engine before stopping.

Note: In case of emergency. the engine may be stopped by turning the ignition key to the nOFF" position.

&CAUTICN& Always remove the key when leaving the

tractor unattended, even if for lust a few minutes. Prevent accidents, don't give children or unauthorized penons an opportunity to oper. ate this machine.

THROnLE CONTROL

The throttle control regulates the speed of the engine as measured in RPM (Revolutions Per Minute). This control should not be used '0 regulate the ground speed of the tractor.

The engine in your new Wheel Horse has been designed with a special governor that limits tl1e en� gine RPM. Unlike an automobile, tl1i5 governor allows 1he engine to operate most effiCiently at a �ef speed, and protects it from damage caused by excessive RPM. Always run the engine with throttle control set at � to full speed.

- 5 -

The engine MUST be operating at a minimum of �"" throttle whenever the trador is in use. Using the tractor while the engine is operating at less than % throttle may result in extensive damage to the automatic transmission.

CHOKE CONTROL

The choke control activates a IIbutterfly" valve ;n the carburetor. This valve limits the amoynf of row oir available to the carburetor. If the choke is "OPEN" the carburetor has an unrestricted flow of raw air. If the choke is "CLOSED", the amount of raw air available is limited. thus cau�in9 the intoke of the engine to draw a higher fuel-fa·air mixture from the carburetor.

Choking the engine is required when the engine is storted cold. Warm engines may not need choking.

FUEL SPECIFICATIONS

When the tractor requires refueling. fill the tonk with 0 good grade (90 octane minimum) of regular or low leaded' gasoline. DO NOT INTERMIX REGULAR AND LOW LEADED GASOLINES. DO NOT MIX OIL WITH GASOLINE.

&CAUTICN & Handle fuel with <or. - it Is highly flam­

moble. Use only approved fuel container. Never add fuel while the engine ;5 running. Fill fuel fank outdoors with extreme care. Never fill fuel tonic indoor •. Replace gasoline cap securely and wipe up all spilled fuel.

OIL SPECIFICAnONS

To protect your new Wheel Horse, check the engine oil level before each use. For maximum protection under all operating conditions use API Service ClassiM ficatioll "SC" oil. Oil carrying the former API Service Classification IIMS" may also be used.

Refer to the "Maintoining Your Tractor" section of this manuol for more detailed information (Page 10).

CORRECT AUTOMATIC

TRANSMISSION OPERATION

During cold weather, start the engine with the parking brake engaged. nis releases the trans.. mission from the engine and allows the engine to turn freely. Run the engine at full throttle for two minutes to allow engine to warm-up. Depress the Broke/Return to Neutral Pedal ancl disengage the parking brake. For temperatures between O°F and 30°F allow .he transmiSlion to run in neutral for 5 minutes before attempting to set the unit into motion. For temperatures be. low O°F allow the transmission to run in neutral for 10 minutes before attempting to set the unit in motion. Failure to do so may result in exten_ sive internal transmission damage.

TO GO FORWARD

.&. CAUTION .&. Before the trodor will move either forward

or backward, the parking brake must be dis­engaged. ALWAYS depress the Brake-Return 10 Neutral Pedal while disengaging the Parking Brake.

The motion of your tractor is controlled by a single "Motion Control Lever", To go forward, simply push .l"Ie lever forward. The farther forward the lever Is pushed, the faster the troctor will go.

.&. CAUTION .&. for sofe operation, neve, move the Motion

Control Lever too rapidly I especiaUy on grades.

By adjusting the Motion Control lever, the forward speed of the troctor can be regulated without adjust. ing the engine throttle control. For heavy pulling. moving the control lever toward neutrol reduces troctor ground speed and increases pulling power much the some as shifting 10 a lower gear with 0 mechanical transmission.

TO GO BACKWARD

To reverse: the motion of t�c tractor, return the motion control lever to the neutrol position, and pull the lever bock. The further bock the lever is the faster the troctor will go in reverse.

TO STOP

Stopping the trodor from either forward or reverse direction can be achieved by one of two methods:

1 . Return the Motion Control lever to its Neutral Position.

2. Depress the "Broke (Return to Neutral)" pedal.

Activating the Broke (Return to Neutral) pedal auto· matically returns the "Mofion Control Lever" 10 its neutral position. The Brake (Return to Neutral) pedal will hold the Motion Control Lever in the Neutral Position. The pedal must be released before the Mo· tion Control Lever can be moved either forward or back.

The tractor is stopped by a "dynamic braking" action inside the hydrostatic transmiuion. Any time the Motion Control Lever is returned to the neutral position the tractor should come to a stop. If the tractor "creeps" on a level surface with the Motion Control Lever in Neutral, consult the "Maintaining Your TroctorU section of this manual, and follow the instructions described under "Transmission· Neutral Adjustment".

When operating your tractor on a slope you can initially stop the 'rador by depressing the HBrake�·. To preven' the tractor from rolling, release the brake pedal and move the motion control lever in tho 0ppoli'e direction of the roll.

PUSH VALVE

Because of the "dynamic brake" feature of the hydrostatic transmission, the tractor con be pushed for only a few feet before the rear wheel will "lock". If for some reason the tractor must be pushed. the manual byposs "Push Valve" must be opened. The valve is located at the reft front of the transmission.

II con be opened or closed by inserting a screw· driver between the left foot rest and the left side of the tractor frame. To OPEN the valve turn one revo· Ivl;on COUNTERCLOCKWISE. T9 CLOSE the valve tv," the" valve CLOCKWISE before operating the tractor.

OPERATION OF THE TRACTOR:

WITH MOWERS

&,CAUTION&, Keep all shields ond mower discharge chute

in place. Never attempt to clear discharge areas or mower blades without disengaging the PTO cluh:h and removing the ignition key.

For best operation on average lowns, operate the engine at full throttle while controlling the ground speed with the 1ransmission. The tractor should operate at 2 to 3.S MPH while mowing gross." Un­even cutting is often the result of exceuive ground $peed. 10 correct, reduce the ground speed with the 1ransmission. Average lawns are usually cut at a

height between 2 and 3 inches. Toll grass and weeds should be cut with the mower in it's highest position, making a second poss CUlling to the height desired.

Always. keep the mower blades sharp.

• A verage walking speed is approximately 2.5 MPH.

WITH A SNOW THROWER

&. CAUTION &. Thoroughly insp&ct the area where the snow­

thrower is to be used. Remove all door mats, sJeds, boards and other foreign objetts. Neve" make any adiustments while the engine is rvn .. ning. Never try to clear the chute while the engine is running.

Snow removal will vary greatly with the condition of each snowfall. lighl fluffy snow will be cleared with ease. Heovy wet snow will be more difficult. It is advisable to coot the auger and chute with a light coat of wax or paroffin to keep snow from sticking. Best resuhs are usuolly ottained when the troctor ground speed is sct at 1 10 2 MPH."

Experience will teach you not to blow snow into the wind.

Caution should be exercised whenever the snow thrower is engaged. The auger is capable of picking up sticks, stones and other foreign objects and ex­pelling them with great velocity. Always aim the dis­charge chute awoy from persons or objects sublcd to harm.

Caution should also be exercised if the chute should become clogged. Always shut off troctor before deor· ing the chute or making any type of adiustments.

Tire chains and wneel weights are recommended for use with the snow thrower.

WITH A DOZER BLADE AND GRADER BLADES

Although the front end dozer blade is generally used for snow rem.,val. it con also be used for moving dirt. sand or gravel. Care should be taken and a slow ground speed should be maintained whenever the blade is used. Impact with a solid obiect may result in iniury to the operator and/or damage to the blades.

Grader Blades are genero!ly preferred for leveling sand, dirt or gravel. The operation of these blades is s;milar to that of a dozer blade. The rear mount blade requires a Wheel Horse 'slot or clevis hitch (deal· ar installed option).

When using any of these attachments with the troc� for, front wheel weights should be used to increase front wheel traction. Reor wheel weights and tire choins may also be needed to increase rear wheel traction.

WITH A TILLER

The Wheel Horse 36" tiller does on excellent job of preparing gardens for planting.

Caution should be exercised when tilling virgin ground or clay as the tiller may have 0 tendency to push the tractor. This con be correded by raising the tiller with the ottochment lift so the tiller pene­rates only the very top of the soil. The tiller can be relowered to its full depth on following posses.

• A verage walking speed is approximately 2.5 MPH.

&. CAUTION &. If Ihe tiller .ram to push tho ,,"octor, .hut

thB tiller off immediately by di5engaging the PTO Clulch.

front wheel weights are recommended to improve the steering of the 'rodor.

The slower the tractor's ground speed, the more aggressive 'he action of the tiller. Best results are usually ottained when the tractor ground speed is set at less than 1.0 MPH. *

00 not over.till the soil. Soil tilled excessively will not hold water, and will compad easily.

WITH PLOWS, DISC, CULTIVATORS

AND HARROW

Plows and disc require maximum trodor efficiency, Cleat tires, or tire chains, 0$ well as whee' weights will Increase tho rear tire traction. Front wheel weights will add to the steering control of the tractor.

The Wheel Horse clevis hitch (deoler installed op· tion) is used for plows. disc and cultivafor, whereas the harrow attaches to the drowbar hitch.

There are two methods of preparing a seed bed for planting.

1. Use a tiller, which wiU prepare the soil in one operotlon.

2. Use 0 plow to turn the ground, a disc to break up large clumps, and a harrow to pulverize and smooth the soil.

Plows ore classified by the width of the furrow they will turn. Generally, plows are set to cut 6" to 8" deep.

A disc is used Immediately ofter plowing. The disc will break the large clumps of soil.

After discing, most generally. 0 spiked tooth harrow is dragged over the soil. The spiked tooth harrow helps pulverize the soil and levels 'he seed bed. The soli should now be ready for planting.

The cultivator is used during the growing season to help remove unwanted weeds, and to help aerate plant roots. Generally the width of the cultivator is token into consideration before planting the seed bed to Insure the cultivator fitting between the rows without damaging the crop roots.

WITH A FRONT END LOADER

The front end loader odds a great amOllnt of ver· satility to your new Wheel Horse, but cen be very dangerous to the operator, and damoging to your tractor when not used correctly,

Wheel weights and tire chains can be added, when additional tire traction becomes necessary. WHEel HORSE DOES NOT RECOMMEND ADDING ANY OTHER WEIGHT TO THE REAR TIRES SUCH AS CALCIUM CHLORIDE O R WATER. THIS ADDIlIONAl WEIGHT CAN CAUSE EXTENSIVE INTERNAL DAMAGE TO THE TRANSMISSION.

www.MyWheelHorse.com

The front End loader is designed and built to pick up and load LOOSE materiat It is NOT designed for digging or loading hard or packed material. Abuse of

this type snould be strictly avoided.

An extra measure of caution should be used when transporting any type of material In the FTont End Loader. Carry all such loads low. NEVER CARRY A

LOAD IN THE BUCKET. WHILE THE BUCKET IS RAISED.

350 Ibs. is the maximum load that should ever be ottempted to lift wi'" the Front End Loader. Loads in excess of 350 Ibs. may be damaging to both the trac­tor and the looder.

WITH DRAWBAR TYPE ATTACHMENTS

Many attachments simply use the 'ractor as a tow .. ing vehicle. They are attached or removed from the tractor by the installation or removal of a si ngle draw­bar hitch pin.

Some of the5e attachments are powered by a sep­orate gasoline engine, some ore "ground drivenit' and some are simply towed, such as the dump cart.

In any coso, all these attachments should be ap' proached with the some amount of coution given any m9chanical devite. Always read each "Operating In­

struction Manual" carefully before attempting to use

the attachment. Keep children and pets away from the vehicle when in operation. Never allow any un­authorized personnel to operate the equipment.

Because of the power of the tractor, no problem should be encountered using these attachments under normal conditions. On rough, hilly, or wet terrain, the oddition of wheel weights ond tire chains will mini­mize rear tire slippage.

WHEEL HORSE DOES NOT RECOMMEND ADDING ANY OTHER WEIGHT. SUCH AS WATER OR CALCIUM CHLORIDE. TO THE REAR TIRES. THIS ADDITIONAL EXTRA WEIGHT CAN CAUSE EXTENSIVE TRANSMIS·

SION DAMAGE.

NEVER overfill the engine crankcase with 011. The oil level must not exceed the "F" level on the dipstick.

OIL CHANGES

The engtne oil in your new Wheel Horse should be changed after the first 2 hours of operation. There­after. the oil should be changed of 25 hour intervals (sooner if the tractor is operated under extremely dusty conditions).

To change the e ngine oil. start the engine and al­low the engine to worm up. Shut off the engine and remove the key.

Disconnect the high tenlion wires at the spark plugs to prevent accidental starting of the en­gin •. Unscrew the oil drain plug located on the left lide of the tractor, between the engine and the baHery. Be sur. oil drains completely.

When using the Temperature-Viscosity Chart, select the air temperature most likely to be encountered within the 2S hours of tractor operation.

AIR CLEANER

Dirt induced through improperly installed, poorly serviced, or inodequote air deaner elements, is more often the cause of a worn out engine than long hours of operation. A small amount of dirt will destroy a set of piston rings in a matter of hours. A clogged ele­ment caUIes a richer fuel mixture which wastes gaso· line, and may lead to the formation of harmful sludge deposits_

To prevent any type of dirt or other contami· nates from .ntering the ensine, always cover the air hom when the air cleaner is removed.

Dry type element. should be replaced after 100 hours if engine is operated under good clean air con­ditions - service and replace element more frequently under extremely dusty or dirty conditions. Dry ele­menf$ should be cleaned after about each 50 hours of operation - remove element and tap lightly on a flat surface to remove loose surface dirt. Replace element If dirt does not drop off easily. Do not wash elements In any liquid or attempt to blow dirt off with air hose as this will puncture filter element. When re­placing the element. use only genuine Kohler or

equivalent elements. CarefuJly handle the new ele­ment - do not use if gasket surfaces are bent or twisted. Chec.k the following when installin9 new or serviced element.

1 . Back plate must be securely tightened to car· buretor. Replace back plate if bent or crocked.

2. Gasket surfaces af element must be flat agoinst bock plate and cover to seol effectively.

3. Wing nut must be finger tight - don't over· •

DRI

The precleoner (C· 1 60 only) slips over the dry element trapping much of 'he dirt preventing il from entering the dry element. Servicing of the precleoner is accomplished by wal>hing it in soap and water. rinsing and squeezing out the exce!>s water and anow. ing it to dry. DO NOT Oil THE PREClEANER.

SPARK PLUGS

Engine misfire, or generally poor operation is often caused by a spark plug in poor condition or with in· correct spark gop setting. Always clean aroo around the spark plugs before removing to prevent dirt from getting into the engine.

Spark plugs shoutd be checked at 50 hour interval:,.

Using a 1 3 / 1 6" spark plug wrench, remove the spark plug from the engine.

Check the condition of the plug. Good operating conditions are indicated by spark plugs thot have a light coating of gray or Ian deposit. A dead wt\ite, blistered cooting could indicate engine overheating. A black coating could indicale a n "overrich" fuel mix· ture caused by a clogged air cleoner. or improper carburetor adjustment.

SPARK PLUG CAP 0.025" GASOLINE

Reset Spa,k Plug Gap

If the pi U9 is in good condition, ,.eset the gap at .025" and reploce the plug. Torque to 22 ft. Ibs.

If the plug is not i n good condition, replace the plug.

Never sandblast, wire brush, scrape or other­wise service spark plugs in poor condition. Besf results are obfained with new plugs.

Always remember to check the spark plug for prop­er gap before instolling plugs into the engine.

BREAKER POINTS

The engine operation of your new Wheel Horse is greatly affected by the condition and adjustment of the breaker points. If the point surfaces are burned, or badly oxidized, little or no current will poss and, as a result, the engine may not operate at all, or if it does run, it is tikely to "mi!>sl>. particularly at full throtfle. The points ore located under the cover on

the front right of the engine. Use the follOWing pro­cedure fO check and adjust breaker points gop.

- 1 2 -

www.MyWheelHorse.com

1 . Remove the breaker points cover. 2. Turn the engine over until the breaker points

are' fully opened. 3. Check the condition of the point surfaces. Al­

ways replace badly burned or pitted points. Slightly pitted points can be dressed down with a point file. This should be done ONLY as a TEMPORARY field fix, since points may tend to arc more readily ofter filing. Replace filed points as soon as possible. If the points are oxidized, rub a coarse cloth between the point surfaces. Di'rty or oily points can be cleaned with a cloth, but make sure no particles of lint remain between point surfaces.

4. Measure the gap with a feeler gauge. When tho points ore fully open, the gap should b. .020".

Measure Breaker Point Gap

5. If adjustment is necessary, loosen the gap ad­justing screw, then insert a screwdriver blade into the adjusting notch and shift the movable plate until the .020" gap is attained. Tighten the adjusting screw, and recheck the point gop.

6. Replace the breaker point cover onto the engine. Un�er normal o p e r a t i ng c o n d i t i o n s-, a -certain

amount of buifdup or metal transfer between the point surfaces will occur. If this occurs too frequently and becomes excessive, the condenser may be at fault (See CONDENSER).

CONDENSER If the condenser shorts oui, the coil will be unable

to produce output voltage, resulting i n little or no spark to the spork plugs. On the other hand. if the condenser opens or decreases in capacitance, the out­put voltage will be greatly reduced, and the breaker points will burn excessively. Usually the condenser is replaced every time the breaker points ore changed.

COIL

C-1 60, C-120, B-' 00 Ignition Coil & Condenser

B-80 Ignition Coil & Condenser

The condenser is located next to the ignition coil.

IGNITION COIL The ignition coil does not require servicing on (]

regular basis; however, the coil should be kept in dean condition. The terminals and connections MUST be tight to provide a good electrical connection. The rubber nipple on the high tension lead (spark plug wire) must be in good condition to prevent leakage of current across exposed surfaces.

CARBURETOR ADJUSTMENT Carburetors are adjuste_d in the factory and should

not have to be reset. If, l1owever, <?ne of the following conditions is noted, readjust carburetor immediately as continued operation with incorrect setting can lead to fouled spark plugs, overheating. excessive valve wear or other problems. If block exhaust smoke is nOfed. check the air cleaner first - an "overrich" mixture is usually caused by a poorly serviced, clogged air cleaner -element, not on improperly adjusted corby­retor.

CONDITION

A. Block, sooty exhaust smoke, engine sluggish. B. Engine misses and backfires at high speed. C. Engine storts, sputters and dies under cold

weather starting. D-. Engine runs rough or stalls at idle speed.

POSSIBlE CAUSE/PROBABlE REMEDY

A. Mixture '00 rich - readjust main fuel needle. B. Mixtvre too lean - readiust moin fuel needle. C. Mixture too !ean - turn moin fuel odjustmenl

� turn counterclockwise. D. Idle speed too low or improper idle adjust­

ment - readjust speed then idle fuel needle if needed.

Carburetor Adjustment Chart

If readjusfment becomes necessary, stop the engine, then turn the MAIN and IDLE fuel adjusting screws all the way in until they bottom lightly - don't force them closed as this will damage the needle valves. For preliminary setting, turn MAIN fuel screw out (counterclockwise) 2 full turns and the IDLE 1 1A turns. For final adjustments, start 'engine and allow it to warm up, then operate at full throttle. Turn MAIN fuel in until engine slows down (lean side) then out until it slows down again from over rich setting - note positions of screw at both settings, then set it about halfway between the two. The IDLE fuel setting con t"en be adjusted in the some manner for smoothest idle. Rough idle is often due to the idle speed being set too low - cneck this 'also.
