fe call your machine the PTO HORSE Model •BILT® Roto Tiller-Power Composter
hout this Owner/Operator Manual and in
r literature, we refer to your machine as the RSE Model”. The name aptly describes its 3e ruggedness, and it distinguishes this
m the smaller ECONO-HORSE, PONY® and models, as well as from other models that
n available in the past or that might be I in the future.
;tory dates back to the old Rototiller Corpo- 5 company that introduced rear-tine rotary
tillage to America in 1930. The first rear-tine tillers Rototiller, Inc. built in Troy were manufactured in 1937, in the same building where Garden Way built its first HORSE Model in 1961. We’re still building our tillers at the same location.
Over the years, the PTO HORSE Model has been continually refined and improved. Its performance and reliability have long been recognized by many thousands of serious vegetable gardeners as being unmatched by any othertiller of its size or design.
WARNING TO ALL CALIFORNIA AND OTHER POWER EQUIPMENT OPERATORS
California law, and under the laws of several other states, you are not permitted to operate an I combustion engine using hydrocarbon fuels on any forest covered, brush covered, or grass dl land, or on land covered with grain, hay, or other flammable agricultural crop, without an spark arrester in continuous effective working order.
gine on your power equipment, like most outdoor power equipment, is an internal combustion that burns gasoline, a hydrocarbon fuel. Therefore, your power equipment must be equipped spark arrester muffler in continuous effective working order. The spark arrester must be
id to the engine exhaust system in such a manner that flames or heat from the system will not lammable material. Failure of the owner / operator of the equipment to comply with this
ion is a misdemeanor under California law, and may also be a violation of other state and / or regulations, laws, ordinances, or codes. Contact your local fire marshal or forest service for ; information about what regulations apply in your area.

Introduction i-
Welcome to “Power gardening the TROY-BILT® Tiller way.” Your new PTO HORSE Model Tiller is a useful, productive gardening tool that, with proper care, should last for many years.
Your tiller was designed to easily chop up, shred and bury all sorts of vegetation and organic matter in the garden in addition to preparing seedbeds and cultivating. With op tional tiller attachments it can also be used for furrowing and hilling, as well as light earthmoving and snow removal chores.
The PTO HORSE Model’s design, with powered wheels ahead of the
separately geared Bolo Tines in the rear, gives it an outstanding combination of tilling and com posting capabilities that allows you to enrich your soil far beyond your abilities to do so by hand. This soil enhancement is gained by tilling in
and burying organic materials such as leaves, mulches, crop residues, sod, green manure cover crops and even standing cornstalks! By using this method, you will soon experience better yields in your garden than ever before. This is said to be the greatest single benefit of power gardening “the different, better, and so much more enjoyable TROY-BILT® Tiller way.”
We have tried our best to build your tiller as strong and troublefree as we know how. This, of course, is to our mutual benefit. We have fewer service problems and you have a truly reliable machine.
V E R Y I M P O R T A N T !
Before trying to operate your tiller or PTO Power Unit for the first time, please make sure that you:
Complete all of the tiller assembly steps that are de scribed in the separate As sembly Instructions Manual that came packaged with this Manual.
Completely familiarize your self with all of the operating controls as described in Sec tion 2 of this Manual.
Read and understand all of the Safety Instructions in Section 1 of this Manual.
Read and understand all of the operating procedures for the tiller and the PTO Power Unit, as described in Sections 3, 4 and 5 of this Manual.
REMEMBER ... PRACTICE SAFETY AT ALL TIMES!
You also have a versatile PTO Power Unit...
In addition to being an incredibiy efficient tiller, your machine can be quickly converted into a seifcontained PTO (Power Take-Off) Power Unit that is capable of tow ing or powering various TROY-BILT PTO attachments (see Figure 2).
This ability to convert the tiller into a PTO Power Unit is made possible by the unique design of the Horse Modei’s transmission. As shown in Figure 3, the trans mission is made up of two sepa rate cast-iron housings that are held together by a locking collar, a dowel pin and two swing-bolts.
Each housing has separate drive shafts that are joined by a tine ciutch. This clutch can be engaged or disengaged by moving the Tines/ PTO Ciutch Lever that is located on the left side of the PTO Power Unit transmission.
When the tine attachment is in place, the lever allows you to operate the tiller with the tines disengaged, even when the wheeis are in motion. This tine disconnect feature provides added conven ience when transporting, loading, or unioading the tiller. When the lever is in the engaged position.
Figure 2: The tine attachment can be removed and various powered or nonpowered attachments can be connected to the Power Unit.
the tine ciutch connects the two drive shafts together, transmitting power to the tines.
If the tine attachment is removed (by ioosening the two swing-bolts and sliding the attachment off), the PTO Power Unit can be used to tow moderate loads or dragbehind implements, or to provide engine power to powered station ary attachments such as the TROY-
BILT® Generator, TROY-BILT® PTO Log Splitter and TROY-BILT® PTO Chipper/Shredder. This PTO capa bility truly makes your tiller an allaround, all-season work horse.
For detailed instructions on how to convert your tilier into a PTO Power Unit piease refer to Section 5 in this Manual.
A word about
maintenance...
You can help ensure long-lasting and proper performance from your PTO HORSE Model by always re membering to perform the sched uled maintenance services that are presented in Section 6 of this Manual, and in the accompanying engine manufacturer’s Owner’s Manual.
By treating your machine with good care in the manner described in those pages, your efforts will be returned many times over in the form of a more satisfying and easier operating machine, and with much more bountiful garden ing resuits.
Figure 3: The transmission consists of two housings, held together by swingbolts. Separate “dog” clutches on each drive shaft are engaged and disengaged with the Tines/PTO Clutch Lever.

(b) Never remove gas cap or add fuel to a running engine or to a hot engine. Engine shall be al lowed to cool before refueling.
and operation, and point out other important Safety Instructions.
3. Never allow children to operate the tiller. Never allow adults to operate the tiller without proper instruction.
4. Keep the area of operation clear of all persons (particularly small children), and pets.
(c) Keep matches, cigarettes, cigars, pipes, open flames, or sparks away from the fuel tank and fuel container.
(d) Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors. Use a funnel or spout to prevent spilling.
(e) Replace fuel cap securely and clean up spilled fuel before restarting.
7. Never attempt to make any ad justments while the engine is running or the spark plug wire is connected, except where specifi cally instructed to do so.
SAFETY INSTRUCTIONS
OPERATION
1. Do not put hands or feet near or under rotating parts.
2. Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic.
3.After striking a foreign object, stop the engine, remove the key on electric start models, disconnect the spark plug wire, and thoroughiy i nspect the ti I ier for any damage. Repair the damage before restart ing and operating the tiller.
4. Exercise caution to avoid slip ping or falling.
5. If the machine should start to vibrate abnormally, stop the engine, remove the wire from the spark plug, and check immediately for the cause. Vibration is generally a warning of trouble.
6. Stop the engine, remove the key on electric start models, and dis connect the spark plug whenever you leave the operating position, before unclogging the tines, and when making any repairs, adjust ments, or inspections.
7.Take all possible precautions when leaving the tiller unattended. Shift into “NEUTRAL”, stop the en gine, remove the key on electric start models, and disconnect the spark plug wire to prevent acci dental starting.
8. Before cleaning, repairing, or in specting, stop the engine, remove the key on electric start models, and make certain all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent ac cidental starting. For electrical saftey, always remove the cable from the negative (-) side of the battery (on electric start models) before attempting any repairs or maintenance.
9.Always keep the flap on the tine hood down when operating the tiller, except when using the hiller/ furrower attachment.
10.Never operate the tiller without proper guards, shields, plates, or other safety protective devices in place.
11.Do not run the engine in an en closed area; exhaust fumes con tain carbon monoxide gas, a deadly poison that is odorless, colorless and tasteless. Always make sure there is adequate ventilation when the engine is running.
12.Keep children and pets away.
13.Never operate the tiller under engine power if the Wheel Speed Lever is in the “FREEWHEEL” position. In “FREEWHEEL”, the wheels will not hold the tiller back and the revolving tines could pro pel the tiller rapidly, possibly caus ing loss of control. Always engage the Wheel Speed Lever in either the “FAST” or “SLOW” wheel speed position before starting the engine or engaging the tines with the Wheeis/Tines/PTO Drive Lever. 14.Be aware that the tiller may unexpectedly bounce upward or jump forward and be propelled away from you if the tines should strike or catch extremely hardpacked soil, sod, frozen ground, or buried obstacles such as large stones, roots, or stumps. If you are in doubt about the tiling condi tions, always use the following operating precautions to assist you in maintaining control of the tiller.
(a) Walk behind and to one side of the tiller, using just one hand on the handlebars. Relax your
arm, but use a secure hand grip.
(b) Use shallower depth regulator
settings, gradually working down deeper with each tilling pass.
(c) Use slowerwheel, tine and en gine throttle speeds.
(d) Clearthetillingareaof all
large stones, roots, and other debris.
(e) Avoid applying downward pressure on the handlebars. If necessary, apply slight upward pressure to prevent the tines from digging too deeply.
(f) Always avoid contacting hardpacked soil or sod at the end of a row by reducing the en gine speed and lifting the han dlebars to raise the tines out of the soii.
(g) In an emergency, stop the tines and wheels by shifting the Wheels/Tines/PTO Drive Lever into “NEUTRAL”. If you cannot reach the lever or have lost control of the tiller, LET GO of the handlebars and all controls and do not attempt to restrain the tiller.
15.Do not overload the machine capacity by attempting to till too deeply at too fast a rate.
16.Never operate the tiller at high transport speeds on slippery sur faces.
17.Do not operate til Ier on a slope that is too steep for safety. When on slopes, slow down and make sure you have good footing. Never permit the tiller to free-wheel down slopes.
18.Clear the area of bystanders before tilling.
19.Use only attachments and accessories that are approved by Garden Way Manufacturing Company.
20.Use tiller attachments and accessories when recommended.
21.Never operate the tilier without good visibility or light.
22.Never operate the tilier when fatigued, or whiie under the in fluence of alcohol, drugs, or medication.
23.Do not change the engine governor settings or overspeed the engine.
24.Do not touch engine parts that may be hot from operation. Allow parts to cool before inspecting, cleaning, or repairing.
25.POISON/DANGER-CAUSES SEVERE BURNS. The battery on electric start models contains sulfuric acid. Avoid contact with skin, eyes or clothing. Antidote: EXTERNAL—Flush immediately with lots of water.
INTERNAL—Drink large quantities of water or milk. Follow with milk of magnesia, beaten eggs or vegetable oil. Call physician immediately.
MAINTENANCE
AND STORAGE
1. Never perform any maintenance while the engine is running or the spark plug wire is connected, ex cept where specifically instructed to do so.
2. Keep machine, attachments and accessories in safe working condition.
3. Check all nuts, bolts, and screws at frequent intervals for proper tight ness and to be sure the equipment is in safe working condition.
4. Never store the machine with fuel in the fuel tank inside a build ing where fumes may reach an open flame or spark, or where igni
EYES—Flush with water for 15 min utes and get prompt medical atten tion. Keep out of reach of children.
26. DANGER-BATTERIES PRO DUCE EXPLOSIVE GASES. Keep sparks, flame, or smoking materi als away. Ventilate when charging or using in an enclosed space. Always shield eyes when working near batteries.
27. Please Remember: You can al ways stop the tines and wheels by putting the Wheels/Tines/PTO Drive Lever in “NEUTRAL”, or by moving the Throttle Lever to the “STOP” position. If you have lost control of the tiller, and cannot reach the levers, LET GO of the handlebars and all controls and do not attempt to restrain the tiller. The Forward Interlock Safety System will stop the engine.
28. Look behind and use care when backing. For added safety,
tion sources are present (such as hot water and space heaters, fur naces, clothes dryers, stoves, elec tric motors, etc.).
5. Allow the engine to cool before storing in any enclosure.
6. To reduce fire hazard, keep the engine free of grass, leaves or ex cessive grease.
7. Store gasoline in a cool, wellventilated area, safely away from any spark or flame-producing equipment. Store gasoline in an approved container, safely out of the reach of children.
8. Refer to the Maintenance and Service Section of this Manual if the tiller is to be stored for an extended period.
put Wheel Speed Lever in “SLOW” before reversing.
29. When loading or unloading unit, always disengage the tines and use slower wheel and engine throttle speeds. Use sturdy ramps that are wide and strong enough to support both the tiller and oper ator (tiller weighs between 280 and 325 lbs.). Never go down ramps in “FORWARD” drive as the tiller could tip forward, exposing you to the tines (which should be disen gaged). Always use “REVERSE” drive and back down ramps. To go up ramps, use “FORWARD” drive and follow tiller up ramps.
30. The Forward Interlock Safety System should first be tested for proper functioning every time the tiller or PTO Power Unit is used. See Section 3 in this Manual for the testing procedure to follow.
31. When snowplowing with the optional dozer blade, either remove the tines completely, or disengage the tines with the Tines/PTO Clutch Lever. Revolving tines could be dangerous on slippery sidewalks or driveways.
DECALS
Safety decals and operating in struction decals are located on the handlebars, the operator control panel, the tine hood, the engine, and the transmission. Contact us immediately for replacement decals if any are missing, illegible, or damaged. See your Parts Catalog for the exact location and part number of each decal. Do not at tempt to operate machine if any decals are illegible or missing.

SECTION 2:
Before using your tiller or PTO Power Unit for the first time, be come thoroughly familiar with the operation of the controls by mov ing them to their various positions
while the engine is not running. Taking the time now to fully under stand the location, function, and operation of these controls will greatly add to the productive use,
safe operation, and full enjoyment of your new machine. The proper operation of each control is dis cussed in detail in this Section.
Tiller and PTO Power Unit Controls
1.Wheels/Tines/ PTO Drive Lever
This lever engages power from the engine to the transmission (see Photos 2-1, 2-2, and 2-3). There are three positions of this lever: "FORWARD”, “NEUTRAL” and “REVERSE”.
When you move the lever down to the “FORWARD” position, it raises the engine upward and tight ens the drive belt located between the engine pulley and the transmis sion pulley. The transmission then
drives the wheels and tines in a forward direction. (If the tines are removed and replaced with a PTO driven attachment, the lever will apply power to the attachment.) The lever will remain in “FOR WARD” until you tap or lift it upward and let it go.
When you move the lever all the way up to the “REVERSE” position, it lowers the engine and causes the drive belt to go slack. At the same time, the rubber reverse disc on the engine pulley comes into contact with the transmission pul ley, causing the transmission to rotate the wheels and tines (or any PTO driven attachment) in a re verse direction. The reverse oper ation will continue as long as you hold the lever up. When you re lease the lever, it will automatically return to “NEUTRAL”. This is a safety feature for your protection.
When the lever is in “NEUTRAL”, the engine will continue to run, but power will not be transferred to the transmission.
IMPORTANT
Moving the lever to the “NEUTRAL” position will stop all wheel and tine motion, or power to any PTO driven attachment.
To operate the Wheels/Tines/
PTO Drive Lever:
A. Practice shifting the lever as described next. As you do, note in the accompanying photos the vari ous positions that the clutch roller takes on the belt adjustment block. Your roller should be similarly po sitioned when you shift the lever.
B. For forward motion of the wheels and tines (or to apply power to any PTO driven attachment), push the iever all the way down and release it. See Photo 2-1. To return to “NEUTRAL”, tap or lift the lever up and let it go (Photo 2-2).
2-1: Push lever down for “FORWARD”. The clutch roller (lower photo) will be engaged below the adjustment block.
2-2: Tap or lift lever up to return to “NEUTRAL”. The clutch roller (lower photo) will rest anywhere on the face of the adjustment block, depending upon drive belt length and tension.
C. Before shifting into “REVERSE”, always look behind you to make sure there are no obstacles in the way. Then raise the tines out of the soil by lifting up on the handlebars, and slowly lift the lever all the
way up. See Photo 2-3. To return to “NEUTRAL”, simply let go of the lever.
Please remember that you should never till when in “REVERSE” (al ways disengage the tines with the separate Tines/PTO Clutch Lever before reversing). You should also avoid using “REVERSE” with any PTO driven attachments as they are not designed for reverse operation.
Until you are completely com fortable with handling the machine when it is moving backward, it is a good idea to use “REVERSE” only at slower wheel and engine throttle speeds. Many people never shift into “REVERSE” when the separate Wheel Speed Lever is in the “FAST” wheel speed position. This is a good rule to follow.
2. Forward Interlock Levers
There are two Forward Interlock Levers, one located directly below each handlebar grip. See Photo 2-4. One or both of the interlock levers must be kept squeezed against the handlebar grip(s) when ever the Wheels/Tines/PTO Drive Lever is engaged in “FORWARD”.
If you release both interlock levers before first returning the Wheels/Tines/PTO Drive Lever to “NEUTRAL”, the engine will shut
off. This is a safety feature for your protection should you ever lose control of the machine and cannot stop forward motion by moving the Wheels/Tines/PTO Drive Lever into
“NEUTRAL”.
NOTE: The interlock levers do not affect operation when the Wheels/Tines/PTO Drive Lever is in “REVERSE”.
2-3: Lift handlebars, then lift and hold lever up to go in reverse. Let go of lever to stop reverse motion. (Note that the clutch roller doesn’t move very far from “NEUTRAL” to “REVERSE”.)
To operate the
Forward interlock Levers:
A. Squeeze one of the interlock levers against the handlebar grip before engaging the Wheeis/Tines/ PTO Drive Lever in “FORWARD”. Continue to squeeze one or both of the interlock levers during all forward operation.
B. To stop forward operation in normal use, first shift the Wheels/ Tines/PTO Drive Lever into “NEU TRAL” and then release BOTH in terlock levers. All forward motion will stop, but the engine will con tinue to run.
C. To stop forward motion in an emergency, release BOTH interlock levers. This will cause the engine to shut off, stopping all forward motion.
ACAUTION
TO AVOID PERSONAL INJURY OR DAMAGE TO EQUIPMENT:
• Always place the Wheeis/Tines/ PTO Drive Lever in “NEUTRAL” be fore starting the engine, and before engaging the wheels, tines or other PTO driven attachments.
• Always make sure there are no obstacles behind you before oper ating in “REVERSE”.
• The Wheels/Tines/PTO Drive Lever should automatically return to “NEUTRAL” when you release it from the “REVERSE” position. If it fails to do so, push it down into “NEUTRAL”. Then, immediately re fer to Section 6 of this Manual
for adjustment instructions.
• There should not be any reverse motion if the Wheels/Tines/PTO Drive Lever is not held in the “RE VERSE” position. If there is, the machine is badly out of adjustment and it should not be operated until the condition is corrected. See Sec tion 6 for adjustment instructions.
• Always return to “NEUTRAL” and allow all motion to stop before shifting into “FORWARD” or “RE VERSE”. This pause between shift ing will protect the drive belt, reverse disc, and other transmis sion components from undue wear and damage.
2-4: The Forward Interlock Levers.
AWARNING
To help avoid personal injury, the Forward Interlock Safety System should first be tested for proper functioning every time the tiller or PTO Power Unit is used. See Sec tion 3 in this Manual for the easy testing procedure to follow.

CONTROLS mo FUUCTIONS
3. Wheel Speed Lever
This lever allows you to choose between two different wheel ground speeds: “SLOW” or “FAST”. It also has a “FREE WHEEL” position, in which the wheels are free to turn without the engine running. See Photo 2-5.
When the lever is engaged in either “SLOW” or “FAST” and the Wheels/Tines/PTO Drive Lever is in either “FORWARD” or “REVERSE”, the wheels will turn under engine power.
When the lever is in the “FREE WHEEL” position and the Wheels/ Tines/PTO Drive Lever is in “NEU TRAL”, the machine can be moved (on level ground) by pushing or pulling on the handlebars. The “FREE WHEEL” position is also used when you are operating a PTO driven stationary attachment, in which case you would not want the wheels to move when the Wheels/Tines/PTO Drive Lever is engaged in “FORWARD”.
IMPORTANT
By moving the forward drive belt (see “Changing Belt Speeds” in Section 3) into one of two different belt ranges, you can obtain a total of fod-' different forward wheel ground speeds. There are, however, only two reverse wheel ground speeds (“SLOW” or "FAST”), be cause the rubber reverse disc, not the drive belt, drives the wheels in the reverse direction.
When you shift the lever into “SLOW” or “FAST”, it moves a slid ing clutch inside the transmission to the left or right to engage the slow speed wheel gear or the fast speed wheel gear. When engag ing the clutch, you should roll the wheels forward or backward a few inches to help align the clutch with
the selected wheel gear. When the clutch goes into gear, you will no longer be able to roll the wheels. When you shift the lever into “FREE WHEEL”, the sliding clutch
is disengaged from both wheel gears and the wheels will roll freely. Note that there should not be any “clicking” noise when you’re in “FREE WHEEL”. If there is, shift the lever a little more (either up or down) to eliminate the noise—and the rubbing of the clutch and gear that causes it.
To operate the Wheel Speed
Lever:
A. With the Wheels/Tines/PTO Drive Lever in “NEUTRAL”, roll the wheels a few inches in either di rection while you push the Wheel
A WARNING
Never put revolving tines in the soil when the Wheel Speed Lever is in “FREE WHEEL”. Doing so can cause the tiller to be propelled rap idly by the tines, possibly causing loss of control and serious per sonal injury. Always engage the Wheel Speed Lever in either “SLOW” or “FAST” wheel speed before putting the tines in the soil.

Speed Lever down to the “SLOW” position, or up to the “FAST” posi tion. See Photo 2-5. When the lever is in gear, you will no longer be able to roll the wheels.
B. With the Wheels/Tines/PTO Drive Lever in “NEUTRAL”, move the Wheel Speed Lever in between the “SLOW” and “FAST” wheel speed positions to place the wheels in “FREE WHEEL”.
A CAUTION
TO AVOID PERSONAL INJURY OR DAMAGE TO EQUIPMENT:
• Use the “SLOW” wheel speed position when first learning to op erate the machine and whenever you operate in “REVERSE”.
• Do not shift the Wheel Speed Lever when heading up or down a slope. If the lever is accidentally placed in “FREE WHEEL”, the ma chine could roll out of control.
• Place the Wheels/Tines/PTO Drive Lever in “NEUTRAL” before shifting into “SLOW” or “FAST”. This will prevent damage to the clutch or wheel speed gears.
• Do not attempt to stop the wheels by shifting the Wheel Speed Lever. Always put the Wheels/ Tines/PTO Drive Lever in “NEU TRAL” to stop the wheels.
11
4. Tines/PTO Clutch Lever
This lever is located on the left side of the transmission, just forward of the tiller tine hood.
There are two operating positions: “ENGAGE” and “DISENGAGE”. See Photo 2-6.
When you move the lever to the “ENGAGE” position, it moves the “dog” clutch on the PTO Power ^ Unit drive shaft backward until it engages the “dog” clutch on the tine attachment drive shaft. (If the tines are removed and replaced with a PTO driven attachment, the “dog” clutch on the power unit will engage with the “dog” clutch on the PTO driven attachment). Engine power will then be applied to the tines or PTO driven attachment when the separate Wheels/Tines/ PTO Drive Lever is engaged in “FORWARD” or “REVERSE”.
In the “DISENGAGE” position, the “dog” clutches are disengaged,
and power will not be applied to the tines or PTO attachment.
When operating the tiller, the “DISENGAGE” position allows you to stop the tines while the sep arately controlled wheels continue to rotate. You should use this fea ture whenever you are transport ing, loading or unloading, turning around, or backing the tiller up. You should also disengage the lever before towing or transporting any attachment.
When the tines are removed and a PTO driven attachment that oper ates from a stationary position is installed, the “ENGAGE” position allows you to power the attachment while the wheels on the PTO Power Unit are not moving.
Always place the Wheels/Tines/ PTO Drive Lever in “NEUTRAL” be fore shifting the Tines/PTO Clutch Lever. Doing so will help prevent damage to the transmission that could occur if you try to engage or disengage the separate drive shaft clutches while they are turning under power.
To operate the Tines/PTO Clutch Lever:
A. Put the Wheels/Tines/PTO Drive
Lever in “NEUTRAL”.
B. Pull the Tines/PTO Clutch Lever out and then slide it into the “EN GAGE” or the “DISENGAGE” slot. C. After selecting the “ENGAGE” position, do not immediately shift the Wheels/Tines/PTO Drive Lever into “REVERSE”. Always use “FOR WARD” first, to help align the drive shaft clutches inside the transmis sion. NOTE: The lever should move easily. If it doesn’t, then the “dog” clutch inside the PTO Power Unit transmission may need to be lubri cated. See “Tiller Lubrication” in Section 6 of this Manual.
A CAUTION
TO AVOID PERSONAL INJURY OR DAMAGE TO EQUIPMENT:
• Always disengage the Tines/ PTO Clutch Lever before reversing, transporting, turning around, or loading or unloading the tiller or PTO Power Unit.
• Do not attempt to stop the tines or any PTO driven attachment by disengaging the Tines/PTO Clutch Lever. Always put the Wheels/ Tines/PTO Drive Lever in "NEU TRAL” to stop all motion.
• Read the Owner/Operator Man ual provided with any attachment before attempting to operate the attachment.
2-6: The Tines/PTO Clutch Lever.
5. Depth Regulator Lever
This lever is located at the rear of the tine hood—see Photo 2-7. It is used to regulate the tilling depth of the tines.
To operate the lever, pull it straight back and then slide it up or down
to any of eight different notched settings.
When the lever is moved all the way down until it engages the high est notch in the lever, it places the tines in the “TRAVEL” position. In this position the tines will clear the ground by approximately 2-inches, allowing you to transport the tiller without the tines—which should be disengaged—scraping your lawn or driveway.
For shallow tilling and cultivat ing, you should place the lever in the second or third notch from the top. These positions will allow the tines to dig just a few inches into the soil. The remaining notches are used for deeper tilling (up to 8-inches deep, depending on the soil conditions), and for turning under organic matter.
Further details regarding the proper use of this lever will be found in Section 4 of this Manual (see “Tilling Depths”).
AWARNING
To help avoid personal injury, always place the tines in the “TRAVEL” position before starting the engine. This prevents the tines from touching the ground until you are ready to begin tilling.

6.Handlebar Height Adjustment Lever
This lever is located near the bottom of the handlebars, on the right side of the tiller. See Photo 2-8. It allows you to adjust the han dlebars up or down to any of four different settings.
As a general rule, the handlebars should be adjusted to approxi mately waist level when the tines are 3 to 4-inches in the soil, but you should try different settings to find the one that is most comforta ble for you.

AWARNING
For use with the PTO Chipper/ Shredder Attachment only, the handlebars can be swung 30° to the right side by loosening the mounting bolt at the bottom of the handlebar base. NEVER OPERATE THE TILLER OR OTHER ATTACH MENTS WITH THE HANDLEBARS
SWUNG OUT TO THE RIGHT SIDE. Doing so could result in unsafe handling and personal injury.
ENGINE CONTROLS
The following are descriptions of the controls on your 7 HP Briggs & Stratton Engine or 8 HP Kohler Engine. Additional information on the safe, efficient operation of your engine is given in the engine man ufacturer’s Owner’s Manual which was included in your literature package. Please read that literature carefully and save it for future reference.
AWARNING
To avoid personal injury or dam age to equipment, do not attempt to start your engine at this time.
Complete starting instructions for the engine are given in Section 3, “Operation of Tiller.”
1. Engine Throttle Lever
This lever is located on the right side handlebar (see Photo 2-10). It is used to regulate engine speeds
as well as to start and stop the engine.
In general, faster engine speeds will be required when breaking new ground or tilling under heavy crop residues, but remember to use only as fast an engine speed as is needed to do the job. Try to judge when the engine is providing the proper amount of power—not too little, but not too much. The sound of the engine running will be your best guide.
IMPORTANT
Factory settings of the throttle cable should be satisfactory for most con ditions. If adjustments are needed, refer to Section 6 of this Manual.
To operate the Engine Throttle Lever:
A.When starting the engine, first make certain that the Wheels/ Tines/PTO Drive Lever is in “NEU TRAL”. Then, place the lever ap proximately halfway between the “SLOW” and “FAST” throttle set tings. This position should provide the carburetor with sufficient gas oline flow to start the engine. How ever, you may need to experiment the first few times to find that “just right” starting position.
B.For faster engine speeds move the lever forward toward the “FAST” setting; for slower speeds
.......
2-10: The Engine Throttle Lever.
move it backward toward the “SLOW” setting.
C. To stop the engine, move the lever all the way back to the “STOP” position (during normal operation you would first place the Wheels/Tines/PTO Drive Lever in “NEUTRAL” and then release both Forward Interlock Levers before stopping the engine).
13
2. Engine Choke Control
Your erigine is equipped with a manually operated choke control as shown in Photo 2-11 or 2-12. The choke makes starting a cold engine easier by decreasing the amount of air in the carburetor’s air-fuel ratio, thus creating a richer fuel mixture. The use of the choke for starting will vary, depending on air temperature and altitude.
To operate the Choke Control:
A. Before starting a cold engine, set the choke in the “FULL CHOKE”
A CAUTION
Never operate the engine under a load (tines, wheels, or PTO attach ments engaged) without first return ing the choke control to “CHOKE OFF”. Failure to do so can quickly build up carbon deposits that can harm the engine.
3. Engine Recoil Starter
The recoil starter is located at the front of the engine, as shown in Photo 2-13 or 2-14. It is used to start engines that are not equipped with the optional key switch start ing feature.
To operate the Engine Recoil
Starter:
A. When starting the engine, first make certain that the Wheels/ Tines/PTO Drive Lever is in “NEUTRAL”.
B. Place your free hand in the lo cation shown in Photo 2-13 or 2-14 to help stabilize the machine.
C. Grasp the starter rope handle with your other hand and pull the
position. On the 7 HP Briggs & Stratton Engine, move the lever all the way down. On the 8 HP Kohler Engine, move the lever all the way up.
B. When the engine starts, slowly move the lever to the “CHOKE OFF” position (all the way up for the 7 HP Briggs & Stratton Engine; all the way down for the 8 HP Kohler Engine).
C. If the engine should falter with the choke at “CHOKE OFF”, return
the lever to a position halfway be tween “FULL CHOKE” and “CHOKE OFF”. As soon as the engine runs smoothly, return the lever to “CHOKE OFF”.
D. When restarting an already warm engine, you may not have to use the choke at all. However, if the engine falters or hesitates, try using a “HALF CHOKE” position until it runs smoothly, and then return the lever to “CHOKE OFF”.

4. Key Switch Starter
The key switch starter for the optional electric start engine is located on the right side of the battery hold-down clamp, as shown in Photo 2-15. There are three op erating positions identified on the switch: “OFF”, “RUN” and “START”.
When the key is turned to the “START” position, the battery sup plies an electrical current to the engine’s starter motor which then cranks the engine over at a fast enough speed for starting.
During engine operation, the bat tery is recharged automatically via a small recharging current that the engine sends back to the battery through the electrical system’s re charging line.
. If the electrical system should ever fail to start or stop the engine,
IMPORTANT
If the battery will not be used for oxlondcd periods of time, it should be fully charged before placing it in storage. Before reinstalling the battery after storage, give it a thor ough recharge. See “Battery Care and Maintenance” in Section 6 for charging instructions.
5.Fuel Tank Shut-Off Valve
Your engine is equipped with a fuel tank shut-off valve. It is located underneath the gasoline tank. See Photo 2-16 or 2-17.
This valve stops the flow of gas oline from the fuel tank to the car buretor. Before starting, make sure that the valve is in its OPEN posi tion (rotate counterclockwise sev eral turns) or the engine will quit from lack of fuel shortly after you start it.
NOTE: Close fuel shut-off valve when engine is transported to pre vent fuel leakage from carburetor.
refer to the “Electric Start Trouble shooting” instructions found in Section 6 of this Manual.
To operate the Key Switch Starter: A. When starting the engine, first make certain that the Wheels/
Tines/PTO Drive Lever is in “NEU TRAL”. Also remember to set the Engine Throttle Lever in the start ing position and the Choke Control in the “FULL CHOKE” position (for cold starts).
B. Insert the key firmly into the key switch slot and turn it all the way to the right, to the “START” po sition. When the engine starts, release the key and it will auto matically return to the “RUN” posi
tion. Do not hold the key in the "START” position for longer than a

SECTION 3:
Before you attempt to operate your tiller make sure that you’ve read and fully understand all of the Safety instructions in Section 1 and the Controls information in Section 2. You should also read this Section carefully before start ing your engine.
You should practice with your tiller in an open, level area before you use it in your garden. While practicing, do so without the tines revolving (disengage the tines with the Tines/PTO Clutch Lever).
When you’ve become completely familiar with your tiller, you can begin using it in your garden.
AWARNING
To avoid personal injury or damage to equipment, read the Owner/Operator Manuals provided with any optional accessories or attach ments before operating the tiller or PTC Power Unit. The Manuals pro vide a detailed description of proper use and operation, and point out other important Safety Instructions.
Break-in operation
During the first few hours of new machine operation, you must per form the following maintenance. For subsequent required mainte nance, and the procedures to fol low, please refer to Section 6 in this Manual.
1. CHANGE ENGINE OIL. The en gine oil must be changed after the first 5 hours of new engine opera tion. Thereafter, change the oil after each 10 operating hours. Change the oil more frequently when oper ating in extremely dusty or dirty conditions.
2. CHECK TRANSMISSION GEAR OIL LEVEL. The gear oil levels must be checked after the first 2 hours
of new tiller operation. Thereafter, check the oil levels after every 30 operating hours.

BWÜ
■'.a.', ■
3.CHECK DRIVE BELT TENSION. The tension on the drive belt may need to be adjusted after the first 2 or 3 hours of new operation due to initial belt wear and seating of the belt with its pulleys. Thereafter, check the tension after every 10 operating hours.
4.CHECK BOLTS AND NUTS. Check for loose bolts and nuts after the first 2 hours of new tiller operation. Thereafter, check after every 10 operating hours.
Preparation before starting
Make the following checks and perform the services as required before starting the engine.
1. CHECK ENGINE OIL LEVEL. Check the oil level in the engine crankcase. Do not run the engine unless the proper oil level is maintained.
2. SERVICE AIR CLEANER. Make sure that the air cleaner elements are not dirty.
3. CHECK SAFETY GUARDS. Make sure that all safety guards and cov ers are securely in place.
4. ATTACH SPARK PLUG WIRE. Be sure that the spark plug wire is securely attached to the spark
plug.
5. CHECK ENGINE COOLING SYSTEM. The cooling fins and air intake screen must be clean to ensure adequate cooling.
............................................. ....
6. ADJUST HANDLEBARS. Set the handlebars to a comfortable oper ating height.
7. CHECK BATTERY (Eiectric Start Models). Make sure that the bat tery is properly filled and that all electrical connections are clean and tight.
8. FiLL FUEL TANK WITH GASO LINE. Avoid using gasoline that is not fresh, as stale fuel can cause gum deposits to form in the carbu retor and fuel lines. Fuel should not be stored for more than six months. The use of unleaded gas oline is recommended as it resuits in fewer combustion deposits and
longer engine life. DO NOT MIX OIL WITH THE GASOLINE.
(a) Clean the fuel cap and its sur rounding area before removing the cap.
(b) Use a clean funnel to add fuel to the fuel tank.
(c) Do not fill the tank to the point of overflowing. Fill to within Ta-inch of the top of the tank to prevent spiils and to allow for fuel expansion.
(d) For 7 HP Briggs & Stratton Engines: use clean, fresh, lead-free automotive gasoline (leaded gas oline may be used if unleaded is unavailable). Use gasoline that has a minimum octane rating of 77. Do not use gasoline containing Meth anol. The use of gasoline which contains alcohol (such as gasohol) is not recommended. If you are
16
using gasohol, refer to the Briggs & Stratton Operating and Mainte nance Instructions booklet for specific cautions and recommen dations for this type of fuel.
(e) For 8 HP Kohler Engines: use fresh, clean, unleaded regular auto motive gasoline with a pump sticker octane rating of 87 or higher. (Leaded “Regular” grade gasoline is an acceptable substitute). The fuel tank capacity is Vk gallons.
(f) Replace the fuel cap securely before starting the engine.
A DANGER
GASOLINE IS HIGHLY FLAMMABLE AND ITS VAPORS ARE EXPLOSIVE. FOLLOW THESE SAFETY PRAC TICES TO PREVENT INJURY FROM FIRE OR EXPLOSION!
•Never fill tank when engine is running or still hot from operation. Allow engine and muffler to cool at least 2 minutes before refueling.
•Do not allow open flames, sparks, matches or smoking in the area.
•Fill fuel tank outdoors in a wellventilated area. Wipe up any spills and move tiller away from gasoline fumes before starting engine.
•Use only an approved gasoline container and store safely out of reach of children.
•Store gasoline and tiller in a well-ventilated area. Do not store where vapors may reach an open flame or spark, or where ignition sources are present (such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc.)
•Allow engine to cool before stor
ing in any enclosures.
• Never bring a gasoline can near the battery posts on electric start model tillers. A short circuit caused by touching the positive (+) post and any metal could cause an ex plosion of the gasoline or of bat tery gases.
Test operation of Forward Interlock Safety System
The Forward Interlock Safety System consists of an electrical grounding system that connects the two Forward Interlock Levers on the handlebars to the ignition system of the engine. One or both of the Forward Interlock Levers must be kept squeezed against the handlebar grip(s) whenever the Wheels/Tines/PTO Drive Lever is engaged in “FORWARD”. If you release BOTH interlock levers be fore first moving the Wheels/Tines/
PTO Drive Lever to “NEUTRAL”, the interlock system will ground out the engine’s ignition system and stop the engine. The interlock system also prevents the engine from start ing if the Wheels/Tines/PTO Drive Lever is engaged in “FORWARD”.
Because the interlock system is an electrical/mechanical device, it is subject to wear or possible fail ure. Therefore, the interlock sys tem should be checked for proper operation each time the tiller or PTO Power Unit is used.
^ DANGER
The Forward Interlock Safety Sys tem is designed for your safety. Never attempt to disconnect or to otherwise defeat the purpose of this system. If the interlock system fails to operate properly, immedi ately contact the TROY-BILT Tiller Technical Service Department. Do not operate the tiller or PTO Power Unit until the system has been re paired and is functioning properly. Always test the system prior to each use.
How to check the interlock system:
1. Move the machine outdoors and park it on level ground. Make sure the area around you is clear of any obstacles.
2. Check to make sure that the Forward Interlock Wire Harness
OPERATION OF TILLER
plug at the bottom of the handle bars is firmly connected to the wire harness receptacle located on the top, right side of the transmission. See Photo 3-2.
3. Place the Wheel Speed Lever in
“SLOW” and the Tines/PTO Clutch
Lever in “DISENGAGE”.
4. Start the engine as described on Pages 18-19. Set the throttle lever in a “SLOW” running position and ailow the engine to warm up. 5. Squeeze one of the Forward Interlock Levers against the handle bar grip and then push the Wheels/ Tines/PTO Drive Lever all the way down to “FORWARD”. See Photo 3-3. As the tiller starts to move

forward, release the Forward Inter lock Lever briefly. If the system
is working properly, the engine should start to shut off when you release the lever. If It does, quickly squeeze the lever against the han dlebar grip and then return the Wheels/Tines/PTO Drive Lever to the “NEUTRAL” position (tap or lift the lever up and release It). Repeat this test using the other Forward Interlock Lever.
6. If the engine does not start to shut off when the Fonward Inter lock Levers are released, the sys tem is not functioning correctly, and you should stop the engine.
remove the key (on electric start models) and disconnect the spark plug wire from the spark plug. Do
not operate the tiller or PTO Power Unit again until the system is again
functioning properly. See Section 6 in this Manual for some simple troubleshooting checks you can do
to correct a faulty Interlock system.
IMPORTANT
To avoid possible damage to the Forward Interlock Safety System, do not use high-pressure sprays around the wire harness recepta cle or neutral plunger assembly.
Cold weather operation
Before operating the machine in cold weather (below 40 °F) you should take the following steps to protect your engine and transmis sion from possible damage.
1. Use a lighter weight oil in the engine crankcase. See “Engine Oil Maintenance” in Section 6.
2. Allow the engine to warm up thoroughly before putting it under a load.
3. Use fresh, winter grade fuel (gasoline suppliers change the fuel blend seasonally).
4. Use the correct weight gear oil in the PTO Power Unit transmis sion. See “Transmission Gear Oil Maintenance” in Section 6.
5. While the engine is warming, place the Wheel Speed Lever in “FREE WHEEL”, block the wheels to prevent them from moving, and
put the Tines/PTO Clutch Lever in “DISENGAGE”. Then squeeze one of the Forward Interlock Levers against the handlebar grip and shift the Wheels/Tines/PTO Drive Lever into “FORWARD”. This will rotate the drive shaft inside the transmis sion and help to warm the trans mission gear oil.
6. Do not try to move the machine if the wheels are frozen to the ground. First melt the ice with warm water.
Starting and stopping the engine
A DANGER
To avoid personal injury, do not run engine in an enclosed or poorly vented area. Engine exhaust con tains carbon monoxide, an odor less and deadly gas.
To start the engine:
IMPORTANT
Use the following steps to practice starting and stopping the engine ONLY. Do not attempt to drive the tiller or PTO Power Unit until you have read ALL of the operating instructions in this Section and in Section 5.
1.Place the Wheels/Tines/PTO Drive Lever in “NEUTRAL” (Photo 3-4). To find “NEUTRAL” (while the engine is not running), push the lever down until it engages in “FORWARD”. Then tap or lift the lever up and release it.
2.Lower the Depth Regulator Lever until the tines are off the ground (Photo 3-4).
3.Put the Wheel Speed Lever in either “SLOW” or “FAST” (Photo 3-4). Be sure to roll the wheels
while shifting the lever until the
wheels are engaged.
NOTE: If using a PTO driven sta tionary attachment, put lever in “FREEWHEEL” and place blocks around all wheels to prevent equipment from moving.
4. Move the engine throttle lever forward, away from the “STOP” position (Photo 3-4).
5. Put the Tines/PTO Clutch Lever in the “DISENGAGE” position— Photo 3-4. (Use the “ENGAGE” po sition if you want the tines to turn or if you want to apply power to a PTO driven stationary attachment). 6. Move the choke control to the “FULL CHOKE” position (Photo 3-5 or 3-6). NOTE: A warm engine may start without choking.

2. Move the engine throttle lever to the “STOP” position (and turn the key to “OFF” on electric start
models). Remove the key for safekeeping.
IMPORTANT
If turning the key to “OFF” or mov ing the throttle lever to “STOP" does not shut the engine off, you can move the choke control to the “FULL CHOKE” position. This will flood the engine and cause it to stall. Use this procedure only in emergencies, as continued use can be harmful to your engine.
Starting the Electric Start Engine with the recoil starter rope
If necessary, the electric start engine can be started with the re coil rope. However, before doing so be sure to follow the procedure below that applies to your particu lar situation.
1. If the battery is in good condi tion (not “dead” or damaged), you can leave it on the tiller which allows it to be recharged during engine operation. But, before start ing the engine with the recoil rope, make sure that the battery is filled to the correct level with electrolyte and that all of the cables and wires are properly connected.
2. If the battery is “dead” or dam aged, then it should be removed from the tiller and tested by a qual ified battery mechanic. While the battery is removed, keep the loose terminal on the positive (+) battery cable (if cable is still attached to solenoid) covered with a wrapping of electrical tape and secure the cable to the frame of the battery bracket. This will prevent any pos sibility of sparking from the cable terminal.
3. Before starting the engine with the recoil starter rope, place the key switch in the “RUN” position, the engine throttle lever in the “START” position, and the choke control in the “FULL CHOKE” posi tion (for cold starts).

To operate the tiller
Now that you are familiar with the operation of your engine, foilow these steps for operating your tiller. When first practicing with your tiller, please leave the Tines/ PTO Clutch Lever in the “DISEN GAGE” position and put the Wheel Speed Lever in the “SLOW” wheel speed position.
A WARNING
To avoid personal injury, keep hands, feet, legs and clothing away from the revolving tines.
To begin tilling:
1. Start the engine by following the previous engine starting in structions. Be certain that the Wheels/Tines/PTO Drive Lever is in “NEUTRAL” before starting the engine.
2.Test operation of Forward Inter lock Safety System. See page 17.
3.Set the Depth Regulator Lever to the desired digging depth and increase the engine throttle speed (when practicing with the tiller leave the tines in the “TRAVEL” position).
4.Move the Tines/PTO Clutch Lever to the “ENGAGE” position (when practicing with the tiller leave the tines in the “DISEN-
GAGE” position).
5. For FORWARD MOTION of the wheels and tines, squeeze and hold one of the Forward Interlock Levers (see Photo 3-7) against the handle bar grip and then move the Wheels/ Tines/PTO Drive Lever down into “FORWARD”.
6. As the tiller moves forward, re lax and let the wheels pull the tiller along while the tines do the dig ging. Walk behind and to one side of the tiller (walk on the side that is not yet tilled to avoid making foot prints in the freshly tilled soil),
and lightly, but securely, grip the handlebars with one hand. See Photo 3-8.
Allow the machine to work at its own pace. Pushing it forward in an attempt to make it go faster will only make the tiller harder to con trol. Also, please do not push down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes the weight off the wheels, reduces traction, and causes the tines to attempt to propel the tiller instead of just digging. This can
if / :/
' " V1/- 1
cause the tiller to hop and skip rapidly across the garden.
7. TO STOP FORWARD MOTION: Tap or lift the Wheels/Tines/PTO Drive Lever up to “NEUTRAL” and then release BOTH Forward Inter lock Levers.
8. TO STOP FORWARD MOTION IN AN EMERGENCY: Let go of ALL handlebar control levers (this will shut off the engine).
9. For REVERSE MOTION:
(a) Do not till while in “REVERSE”.
(b) Put the Wheels/Tines/PTO Drive Lever in “NEUTRAL” and reduce the engine throttle speed. Make sure the area be hind you is clear.
Put the Wheel Speed Lever in the “SLOW” position.
Put the Tines/PTO Clutch Lever in “DISENGAGE”.
Lift the handlebars until the tines clear the ground and then lift and hold the Wheels/Tines/ PTO Drive Lever all the way up (you do not need to squeeze a Forward Interlock Lever while in “REVERSE”).

TO HELP AVOID PERSONAL INJURY OR DAMAGE TO EQUIPMENT:
• Always make sure there are no obstacles behind you before oper ating in “REVERSE”.
• Disengage the tines, reduce the engine throttle speed and move the Wheel Speed Lever into the “SLOW” position before operating in “REVERSE”. Avoid using “FAST” wheel speed until you are sure you can control the machine at this faster speed.
10. TO STOP REVERSE MOTION: Release the Wheels/Tines/PTO Drive Lever and it will automatically return to the “NEUTRAL” position. (The Forward Interlock Levers will not stop “REVERSE” motion.)
TO STOP THE ENGINE:
Move the engine throttle lever to the “STOP” position (and turn the key to “OFF” on electric start models). Remove the key for safe
keeping.
Turning around
It’s easy to turn your tiller around. All you have to do is find the balance point between the en gine and the tines and then let the power driven wheels do the work as you push sideways on the handlebars in the direction of your turn.
Practice the following maneuver in a large open area before taking your tiller into the garden.
AWARNING
To help avoid personal injury, al ways put the Tines/PTO Clutch Lever in the “DISENGAGE” posi tion before turning the tiller around.
1. At the end of a row, put the Wheels/Tines/PTO Drive Lever in “NEUTRAL” and reduce the engine throttle speed.
2.Put the Tines/PTO Clutch Lever in “DISENGAGE”.
3.Resume forward operation and lift the handlebars until the tines are out of the ground. Then, using the wheels as a pivot point to bal ance the engine and tines, PUSH the handlebars to swing the tiller around. Af all times, be careful to
keep your feet and legs away from
the tines (which should be disen gaged). Let the powered wheels do the work ... the inside wheel will pivot in place while the outside wheel drives the machine around. See Photos 3-9 and 3-10.
NOTE: Use “REVERSE” if neces sary, to turn in a limited space. 4. When the turn is completed, shift into “NEUTRAL” and lower the handlebars. When you are ready to begin a new row, put the Tines/PTO Clutch Lever in the “ENGAGE” position and resume “FORWARD” operation.

Transporting your tiller
The power driven wheels allow you to easily move your tiller to and from your garden when the engine is running. Or, you can move the tiller (on level ground) without the engine running by us ing the “FREE WHEEL” position on the Wheel Speed Lever.
A WARNING
To help avoid personal injury, al ways put the Tines/PTO Clutch Lever in the “DISENGAGE” posi tion before transporting, loading or unloading the tiller.
To transport tiller:
1.Place the Tines/PTO Clutch Lever in the “DISENGAGE” position.
2.Move the Depth Regulator Lever all the way down to the “TRAVEL” setting.
3.If using engine power, select the
“SLOW” or “FAST” wheel speed position on the Wheel Speed Lever and use the Wheels/Tines/PTO
Drive Lever to drive the wheels.
4. If the engine is stopped, put
the Wheel Speed Lever in “FREE WHEEL” and manually move the machine.
To load or unload tiller:
1. Use loading ramps that are wide and strong enough to support both the machine and the operator (ma chine weighs between 280 and 325 pounds).
2. Place the Tines/PTO Clutch
Lever in the “DISENGAGE”
position.
3. Put the Wheel Speed Lever in the “SLOW” wheel speed position and reduce the engine throttle speed.
4. TO GO UP RAMPS, use “FOR WARD” drive and follow the tiller up the ramps (Figure 3-11).
5. TO GO DOWN RAMPS, use “RE VERSE” drive and back down the ramps. Never go down the ramps
in “FORWARD” drive as the tiller could tip forward, exposing you to the tines (which should be disen gaged). See Figure 3-12.
Changing belt speeds
Your Tiller has both “LOW” and “HIGH” speed belt ranges. By moving the belt from one range to the other you can obtain a total of four different forward wheel speeds and two different tine speeds. These extra wheel and tine speeds permit you to tailor your tiller’s action to your specific needs in the garden, with less strain on the engine.
Changing from one belt range to the other is simply a matter of mov ing the belt from one set of grooves on the engine and transmission pulleys to the other set of grooves. See Photo 3-13. This change can be made very quickly in the field and without any tools.
3-13: Belt range positions.
By combining the use of the “LOW” and “HIGH” speed belt ranges with the “SLOW” and “FAST” speed positions on the Wheel Speed Lever, you can ob tain four different forward wheel speeds (Figure 3-14). The two dif ferent tine speeds (Figure 3-14) are determined by the belt range position alone.
At 3000 RPM (Revolutions Per Minute) engine speed, the w/heel and tine speeds are:

When the tiller is operating in “REVERSE”, the wheels and tines are powered by the rubber reverse disc and not the belt. Therefore, you have only two reverse speeds as determined by the “SLOW” and “FAST” positions of the Wheel Speed Lever.
IMPORTANT
Proper belt tension is critical to good performance. Check the ten sion after the first 2 hours of new operation and every 10 hours thereafter. See "Drive Belt Mainte nance" in Section 6.
To change from “LOW” range to “HIGH” range:
AWARNING
To help avoid personal injury, stop the engine, remove the electric start key, disconnect the spark plug wire, and let the engine and muffler cool before changing belt speeds.
1.Place the Wheels/Tines/PTO Drive Lever in “NEUTRAL”.
2.While kneeling on the left side of the tiller, create slack in the belt by reaching over to the right side of the pulleys and pushing in on the center of the belt with your finger. Then use your left hand to work the belt part way into the forward groove of the transmission
(lower) pulley. See Photo 3-15. Now go to the other side of the tiller and finish seating the belt In the groove.
3. On the left side of the tiller, work the belt part way into the forward groove of the engine (upper) pul ley. See Photo 3-16. Then go to the other side and finish seating the belt. NOTE: If additional clearance is needed to fit the belt over the engine pulley, simply raise the Wheels/Tines/PTO Drive Lever into the “REVERSE” position. This will lower the engine pulley.
4. Check both sides of the pulleys to make sure that the belt is fully seated in the “HIGH” range grooves of each pulley.
To change from “HIGH” range to “LOW” range:
3-17: With drive lever held in “RE VERSE”, move belt on engine pulley into rear groove.
1.Place the Wheels/Tines/PTO Drive Lever in “NEUTRAL”.
2.Stand on the left side of the tiller and use your right hand to hold the Wheels/Tines/PTO Drive Lever up in the “REVERSE” posi tion. Then use your left hand to move the belt part way into the rear groove of the engine (upper) pulley. See Photo 3-17. Now go to the other side of the tiller and fin ish seating the belt in the groove.
3.While still holding the drive lever in “REVERSE”, move the belt into the rear groove of the transmission (lower) pulley. Do this on both sides of the tiller. See Photo 3-18.
4.Check both sides of the pulleys to make sure that the belt is fully seated in the “LOW” range groove of each pulley.

Choosing wheel and tine speeds
Your tiller offers a wheel and tine speed combination for every tilling task and situation in the garden. With a little experimenting, you can soon find the proper tilling depth, engine throttle setting, and wheel and tine speeds that are just right for the piece of soil you are work ing on. What this means is;
1. You advance the throttle lever to keep the engine running at a suffi cient power level to do the job.
2. You have the depth regulator set in a notch which is not so deep
that it causes the engine to labor or causes the tiller to jump.
3. You have the tines turning over fast enough to really break up the soil with a minimum number of passes. When your tiller is working properly, you can hear that the engine is not laboring very hard and see that the tines are breaking up the soil into small, thoroughly tilled bits. At the proper match
of wheel and tine speeds, you will get the job done quickly, and achieve results which are better and more satisfying.
To help guide you in your selec tions of wheel and tine speeds, please refer to the following chart.
A WARNING
The “HIGH” belt range and “FAST” wheel speed combination will propel the tiller at a fast pace.
To help avoid personal injury when first using this belt range/wheel speed combination, reduce the en gine throttle speed setting to a slower setting.
