Section

Safety

Training

1. Carefully read this Owner’s Manual, the separate Engine Owner’s Manual, and any other literature you may receive. Be thoroughly familiar with the controls and the proper use of the tiller and its engine. Know how to stop the unit and disengage the controls quickly.

2. Never allow children to operate the tiller. Never allow adults to operate the tiller without proper instruction.

3. Keep the area of operation clear of all persons, particularly children and pets.

4. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and themselves.

Preparation

1. Thoroughly inspect the area where the tiller is to be used and remove all foreign objects.

2. Put the Wheels/Tines/PTO Drive Lever into NEUTRAL before starting the engine.

3. Do not operate the tiller without wearing adequate outer garments. Avoid loose garments or jewelry that could get caught in moving parts.

4. Do not operate the tiller when barefoot or wearing sandals, sneakers, or light footwear. Wear protective footwear that will improve footing on slippery surfaces.

5. Do not till near underground electric cables, telephone lines, pipes or hoses. If in doubt, contact your telephone or utility company.

6. Warning: Handle fuel with care; it is highly flammable and its vapors are explosive. Be sure to take the following precautions:

a. Store fuel in containers specifically

designed for this purpose.

b. The gas cap shall never be removed

or fuel added while the engine is running. Allow the engine to cool for several minutes before adding fuel.

c. Keep matches, cigarettes, cigars,

pipes, open flames, and 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 spillage.

e. Replace all fuel tank and container

caps securely.

f. If fuel is spilled, do not attempt to

start the engine, but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.

7. Never make adjustments when engine is running (unless recommended by manufacturer).

Operation

1. Do not put hands or feet near or under rotating parts. Do not allow hands or any other part of the body or clothing near the rotating tines or near any other moving part. The tines begin to rotate forward

once the engine starts, the Tines/PTO Clutch Lever is in the ENGAGE position, the Forward Interlock Levers are squeezed closed and the Wheels/Tines/PTO Drive Lever is shifted to FORWARD. The tines rotate in Reverse whether the Interlock Levers are closed or open.

2. Exercise extreme caution when on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Do not carry passengers.

3. After striking a foreign object, stop the engine, remove the wire from the spark plug wire and prevent it from touching the spark plug. Thoroughly inspect the machine for any damage and repair the damage before restarting and operating the machine.

4. Exercise caution to avoid slipping or falling.

5. If the unit should start to vibrate abnormally, stop the engine, disconnect the spark plug wire and prevent it from touching the spark plug, and check immediately for the cause. Vibration is generally a warning of trouble.

6. Stop the engine, disconnect the spark plug wire and prevent it from touching the spark plug whenever you leave the operating position, before unclogging the tines, or when making any repairs, adjustments or inspections.

7. Take all possible precautions when leaving machine unattended. Stop engine. Disconnect spark plug wire and move it away from spark plug. Remove ignition key on electric start models

Section 1: Safety

8. Before cleaning, repairing, or inspect-

ing, stop the engine and make certain all moving parts have stopped. Disconnect the spark plug wire and prevent it from touching the spark plug to prevent accidental starting.

9. The flap on the tine hood must be down when operating the tiller, unless using the Hiller/Furrower attachment.

10. Never use the tiller unless proper guards, plates, or other safety protective devices are in place.

11. Do not run engine in an enclosed area. Engine exhaust contains carbon monoxide gas, a deadly poison that is odorless, colorless, and tasteless.

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 propel the tiller rapidly, possibly causing loss of control. Always engage the Wheel Speed Lever in either FAST or SLOW position before starting the engine or engaging the tines with the Wheels/Tines/PTO Drive Lever.

14. Be aware that the tiller may unexpectedly bounce upward or jump forward if the tines should strike extremely hard packed soil, frozen ground, or buried obstacles like large stones, roots, or stumps. If in doubt about the tilling conditions, 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 one hand on the handlebars. Relax your arm, but use a secure hand grip.

b. Use shallower depth regulator

settings, working gradually deeper with each pass.

c. Use slower wheel, tine and engine

speeds.

d. Clear the tilling area of all large

stones, roots and other debris.

e. Avoid using downward pressure on

handlebars. If need be, use slight upward pressure to keep the tines from digging too deeply.

f. Before contacting hard packed soil

at the end of a row, reduce engine speed and lift handlebars to raise tines out of the soil.

g. In an emergency, stop tines and

wheels by shifting the Wheels/Tines/PTO Drive Lever into NEUTRAL. If you can not reach the lever or have lost control of the tiller, let go of the handlebars and all controls. Do not attempt to restrain the tiller.

15.

Do not overload the tiller’s capacity by attempting to till too deeply at too fast a rate.

16. Never operate the tiller at high transport speeds on hard or slippery surfaces. Look behind and use care when backing up.

17. Do not operate the tiller 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 freewheel down slopes.

18. Never allow bystanders near the unit.

19. Only use attachments and accessories

that are approved by the manufacturer of the tiller.

20. Use tiller attachments and accessories when recommended.

21. Never operate the tiller without good visibility or light.

22. Never operate the tiller if you are tired, or under the influence of alcohol, drugs or medication.

23. Operators shall not tamper with the engine-governor settings on the machine; the governor controls the maximum safe operating speed to protect the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.

24. Do not touch engine parts which may be hot from operation. Let parts cool down sufficiently.

25. POISON/DANGER—CAUSES SEVERE BURNS. The battery on electric

start models contains sulfuric acid. Avoid contact with skin, eyes or clothing. Keep out of reach of children.

Antidotes:

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 a doctor immediately. Eyes– Flush with water for 15 minutes. Get prompt medical attention.

26. DANGER– BATTERIES PRODUCE EXPLOSIVE GASES. Keep sparks, flame

or smoking materials away. Ventilate when charging battery or using in an enclosed space. Always wear safety goggles when working near battery.

27. Please remember: You can always stop the tines and wheels by releasing all controls, or by moving the ignition switch and/or throttle control lever on the engine to OFF or STOP.

28. To load or unload the tiller, see the instructions in Section 4 of this Manual.

29. Use extreme caution when backing or pulling the machine towards you.

30. Start the engine carefully according to instructions and with feet well away from the tines.

31. Never pick up or carry a machine while the engine is running.

32. When loading or unloading the tiller, always disengage tines and use slower wheel and engine throttle speeds. Use sturdy ramps wide and strong enough to easily support the tiller (280-to-325 lbs., depending on model) and operator. Never go down ramps in FORWARD drive—the tiller could tip forward, exposing you to the tines (which should be disengaged). Always use REVERSE drive and back down ramps. To go up ramps, use FORWARD drive and follow the tiller.

33. The Forward Interlock Safety System should be tested for correct functioning every time the tiller or PTO power unit is used. See Section 4 in this Manual.

34. If using the optional Dozer Blade, either remove the tine attachment, or disengage the tines with the Tines/PTO Clutch Lever. Revolving tines are dangerous.

IMPORTANT: Refer to the separate engine manufacturer’s Engine Owner’s Manual for information about the controls on the engine.

NOTE: All references to left, right, front and rear of the machine are based on a position behind the handlebars and facing forward.

PTO Attachments Feature

In addition to powerful tilling capability, you can quickly convert your machine into a PTO (Power Take-Off) Power Unit that is capable of towing or powering various TROY-BILT attachments.

You can access this capability by removing the tines attachment (powered by the PTO Power Unit). The PTO Power Unit is then available for engine powered attachments, or for pulling or towing nonpowered attachments. See Section 4, PTO Power Unit for detailed information on installing and operating TROY-BILT PTO attachments.

Wheels/Tines/PTO Drive Lever

Use the Wheels/Tines/PTO Drive Lever (A, Figure 3-1) to engage and disengage power to the transmission.

This lever has three operating positions: FORWARD, NEUTRAL and REVERSE.

• FORWARD is engaged when the lever is

moved down until the clutch roller (G, Figure 3-2) engages into the detent position under the adjustment block (H, Figure 3-2). You will definitely feel the lever engage into this position.

Use the FORWARD setting to move the wheels and tines forward, or to apply power to an optional PTO (Power Take Off) attachment. (See also

Forward

Interlock Levers.)

To stop the wheels, tines or any PTO attachment, move the lever to NEUTRAL by tapping the lever upwards (Figure 3-3) and releasing.

• REVERSE is engaged when the lever is

pushed (with an open palm) all the way up and held in that position (Figure 3-4). Use this setting to move the wheels in reverse. To stop moving in reverse, release the lever; it automatically returns to the NEUTRAL position.

IMPORTANT: Do not operate the tines or any PTO attachment in REVERSE.

• NEUTRAL is this control’s normal non-

operating position. The lever returns to NEUTRAL when it is tapped out of the FORWARD position or released from the REVERSE position. NEUTRAL position is between FORWARD and REVERSE (Figure 3-3). Use this setting to stop the wheels, tines or any PTO attachment.

IMPORTANT: Always shift to NEUTRAL before starting the engine or before engaging the wheels, tines or any PTO attachment.

Forward Interlock Levers

The Forward Interlock Levers (B, Figure 3-1) are attached under each handlebar grip.

You must squeeze at least one of these interlock levers up against the handlebar grip whenever the Wheels/Tines/PTO Drive Lever is engaged in FORWARD position.

Figure 3-1: A– Wheels/Tines/PTO Drive Lever E– Depth Regulator Lever B– Forward Interlock Levers F– Handlebar Height Adjustment Lever C– Wheel Speed Lever G– Engine Throttle Lever D– Tines/PTO Clutch Lever

Before operating your machine, carefully read and understand all safety, controls, operating instructions in this Manual, the separate Engine Owner’s Manual and on the decals on the machine.

Failure to follow these instructions can result in serious personal injury.

WARNING

Section 3: Features and Controls

Figure 3-2: FORWARD position; roller (G) rests under the adjustment block (H).

Figure 3-3: NEUTRAL position; roller (G) rests against middle area of the adjustment block (H).

Figure 3-4: REVERSE position; roller (G) rests against upper area of the adjustment block (H).

Verify Position of Clutch Roller

When you shift between FORWARD, NEUTRAL and REVERSE, the clutch roller at the base of the Wheels/Tines/PTO Drive Lever should be positioned as shown in Figures 3-2, 3-3 and 3-4. Verify the position of the clutch roller as you shift the lever. If it is not positioned correctly, contact the Factory or see your local authorized dealer.

If both Forward Interlock Levers are released before first returning the Wheels/Tines/PTO Drive Lever to NEUTRAL, the engine will stop.

IMPORTANT: The Forward Interlock Levers are a safety control that stops the engine should you lose control while going forward and cannot shift into NEUTRAL.

Wheel Speed Lever

Use the Wheel Speed Lever (C, Fig. 3-1) to select one of three operating positions: SLOW, FAST or FREEWHEEL.

• SLOW – Lever moved all the way down.

Most effective for normal tilling or for low-speed transport.

• FAST – Lever moved all the way up.

Most effective for cultivating or for fastspeed transport.

• FREEWHEEL – Lever in between SLOW

and FAST (wheels will roll freely). Used when transporting the machine on level ground without engine power, and when using stationary PTO attachments.

IMPORTANT: To avoid transmission damage, always move Wheels/Tines/PTO Drive Lever into NEUTRAL before shifting the Wheel Speed Lever.

IMPORTANT: When shifting into SLOW or FAST, gently roll the machine forward or backward to help fully engage the wheel gears. When engaged, the wheels will not turn unless the engine is running and the Wheels/Tines/PTO Drive Lever is engaged in FORWARD or REVERSE.

Tines/PTO Clutch Lever

Use this lever (D, Figure 3-1) to engage or disengage power from the transmission PTO clutch to the tines or any PTO attachment. This control has two operating positions: ENGAGE and DISENGAGE.

• ENGAGE – Lever moved into detent slot

farthest from engine. Use this position to operate tines or other PTO attachments. After shifting to ENGAGE, briefly operate machine in FORWARD to help fully engage the PTO clutch.

• DISENGAGE – Lever moved into detent

slot nearest engine. Use this position to disengage power to tines or other PTO attachments before transporting, loading, turning, or operating in reverse.

IMPORTANT: To avoid transmission damage, always move the Wheels/Tines/ PTO Drive Lever into NEUTRAL before shifting the Tines/PTO Clutch Lever.

Depth Regulator Lever

Use this lever (E, Figure 3-1) to regulate the tilling depth of the tines. This control also has a TRAVEL position, which enables transport with the tines off the ground.

To operate the lever, lift up on the handlebars, pull the Depth Regulator Lever straight back, and then slide it up or down to one of the eight detent height settings.

The eight detent positions offer a range of tine height settings. This enables you to select the height that is most effective for a particular condition. The top detent position is the TRAVEL setting. Use the second or third detent from the top for shallow tilling and cultivating. Use the other detents for deeper tilling and for power composting.

Handlebar Height Adjustment Lever

Use this lever (F, Figure 3-1) to adjust the handlebars to one of two height settings.

1. To change the height, hold the handle-

bars with one hand and loosen the lever in a counterclockwise direction.

2. Move the handlebars to one of the two

preset height settings.

3. Retighten the lever.

NOTE: You can swap the positions of the inside handlebar ratchets to change the two preset settings by approximately four inches higher or lower. See Section 2, Step 2: Attach Handlebar for detailed assembly information.

To 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.

WARNING

Engine Throttle Lever

Use the throttle lever (G, Figure 3-1) to adjust engine speed as well as to start and stop the engine.

Move the lever away from the STOP position before starting the engine. Engine speeds are variable and range between the FAST and SLOW. Use the STOP position to turn the engine off.

NOTE: A secondary throttle lever is located on the front of the 8HP and 10HP engines. A separate On/Off switch may also be available on the engine. (See Engine Owner’s Manual for information.)

Engine Controls

Refer to the engine manufacturer’s Engine Owner’s Manual (included in the tiller literature package) to identify the controls on your engine.

IMPORTANT: An engine On/Off switch, a secondary throttle control, a choke lever and a fuel line shut-off control may be located on the engine. Refer to your Engine Owner’s Manual for detailed information.

Section 3: Features and Controls

The tiller handlebars can be swung out 30oto the right side for use only with the PTO Chipper/Shredder attachment. This is done by loosening the mounting bolt on the handlebar base. Never operate your tiller or attachments, other than the PTO Chipper/Shredder, with the handlebars in the right side position. Doing so could result in unsafe handling and personal injury.

To avoid serious personal injury or damage to equipment, do not start your engine at this time. Complete starting instructions are described in Section 4, Operation.

Keyswitch Starter

The keyswitch starter on electric start models (A, Figure 3-5) has three positions: OFF, RUN and START. Turn the key to START to start the engine. Release the key and it will return to the RUN position. Turn the key to OFF to stop the engine. (Another way to stop the engine is to move the engine throttle lever to the STOP position.)

DANGER

Section 4: Operation

Starting the Engine:

1. With the engine off, place the

Wheels/Tines/PTO Drive Lever (Figure 4-2) in the NEUTRAL position. If in the FORWARD position, tap the lever sharply upward, it should automatically move into NEUTRAL position.

2. Put the Depth Regulator Lever in the Travel position (lever all the way down) so that the tines are off the ground. To do this, lift up on the handlebars, pull the lever (Figure 4-2) back, and push it down all the way to the top detent (notched) position.

3. Move the Wheel Speed Lever (Figure 4-2) to either the SLOW or FAST position. Be sure to roll the wheels while shifting the lever until the wheels engage.

NOTE: If using a PTO stationary attachment, move the Wheel Speed Lever into FREEWHEEL and block the wheels to prevent the equipment from moving (Figure 4-29 on page 29).

4. Move the Tines/PTO Clutch Lever into DISENGAGE position (Figure 4-2).

NOTE: Use the ENGAGE position if you want the tines to revolve or to apply power to a PTO-driven stationary attachment.

5. If engine is equipped with a fuel valve, turn valve to OPEN position as instructed in the separate Engine Owner’s Manual.

6. If engine is equipped with an ON/OFF switch, move the switch to ON.

7. Move engine throttle lever (Figure 4-2) away from STOP.

8. Choke or prime engine as instructed in the separate Engine Owner’s Manual.

9. If not equipped with an electric start system, place one hand on the fuel tank to stabilize the unit when you pull the recoil starter rope. Use the recoil starter rope to start the engine as instructed in the separate Engine Owner’s Manual.

10. If equipped with an electric start system, turn key to START position to crank engine then release when engine starts. If the engine does not start right away, do not hold key at START for more than a few seconds. Release then try again after a short pause. Damage to starter motor can occur if it is cranked more than 15 seconds per minute.

11. If the engine does not start after a number of tries, refer to the Engine Owner’s Manual for specific instructions.

12. When engine starts, move the Throttle Lever to the SLOW position and then gradually move choke lever (on engines so equipped) to OFF or RUN position.

13. Move the throttle speed control to FAST setting when tilling.

Starting Electric Start Engines with the Recoil Starter Rope

You may, at some point, have to start an electric start engine with the recoil starter rope. Before attempting to do so, perform the following applicable steps:

• If you suspect the battery charge is

weak, and there is no visible damage. Disconnect cables from battery and clean both cable terminals, and the battery posts in accordance with the instructions provided in Section 5, Battery Care and Maintenance.

To help prevent serious personal injury or damage to equipment:

• Always place Wheels/Tines/PTO Drive Lever into NEUTRAL before starting engine, and before engaging wheels, tines or other PTO-driven attachments.

• Never run engine indoors or in enclosed, poorly ventilated areas. Engine exhaust contains carbon monoxide, an odorless and deadly gas.

• Avoid engine muffler and nearby areas. Temperatures in these areas may exceed 150oF.

CAUTION

Section 4: Operation

Reconnect the cables and securely tighten to battery posts. The engine will recharge the battery if the battery is still good.

• If you suspect the batter is “dead”, or if

the battery is damaged, disconnect, and remove it. Have it checked by a qualified technician.

• If battery has been removed, wrap cable

terminals at end of positive cable with electrical tape and secure the cable to the battery bracket. This will prevent electrical discharge.

• Before pulling the recoil starter rope,

turn the keyswitch to the RUN position. Move the Throttle Lever away from STOP position and set the choke as applicable. See Engine Owner’s Manual.

Stopping the Engine and Tiller

1. To stop the wheels and tines, move the

Wheels/Tines/PTO Drive Lever into NEUTRAL position and then release both Forward Interlock Levers.

2. Move the engine Throttle Lever to the STOP position. Then on electric start models, turn the key to OFF. Remove the key for safekeeping.

NOTE: The engine may have a separate Throttle Control Lever and ON/OFF switch on the engine. These controls can also be used to stop the engine. See the Engine Owner’s manual for information specific to your engine.

Operating the Tiller

When first practicing, keep the Tines/PTO Clutch Lever in DISENGAGE position and the Wheel Speed Lever in SLOW position.

The following pages provide guidelines for using your tiller effectively and safely in various gardening applications. Be sure to read

Tilling Tips & Techniques, in this Section, before you actually put the tines into the soil.

This is a traditional standard-rotating-tine (SRT) tiller with forward rotating tines. It operates in a completely different manner than counter-rotating-tine (CRT) tillers, or from front-tine tillers.

Moving the Tiller Forward and Tilling

1. Start the engine and gradually increase

engine speed to FAST (see

Starting the

Engine, this Section).

2. Test the Forward Interlock Safety System. See Testing Forward Interlock

System

, this Section.

3. When practicing, set the Depth Regulator Lever to Travel position. Otherwise, set the Depth Regulator Lever to a desired depth.

4. Move Tines/PTO Clutch Lever to ENGAGE position if you want the tines to turn. If practicing, leave in DISENGAGE.

IMPORTANT: Do not move Tines/PTO Clutch Lever to ENGAGE unless Wheels/Tines/PTO Drive Lever is in NEUTRAL. Tiller damage may occur!

5. To move the tiller forward and engage the tines, squeeze and hold either Forward Interlock Lever (Figure 4-3) against the handlebar grip, then move the Wheels/Tines/PTO Drive Lever down to FORWARD position.

To avoid serious personal injury or damage to equipment:

• Always place Wheels/Tines/PTO Drive Lever in NEUTRAL before starting engine, and before engaging wheels, tines or other PTO attachments.

• Be sure there are no obstacles behind you before moving in reverse.

• Wheels/Tines/PTO Drive Lever should automatically return to NEUTRAL when released from REVERSE position. If it does not, move lever to NEUTRAL manually and discontinue use until you adjust the lever. See Section 5,

Checking and Adjusting

Reverse Drive System.

• No reverse motion should occur if Wheels/Tines/PTO Drive Lever is not held up in REVERSE. See Section 5,

Checking and Adjusting Reverse Drive System for adjustment steps.

Do not use tiller unless properly adjusted.

• Always return to NEUTRAL and let all motion stop before shifting to FORWARD or REVERSE.

The Forward Interlock Safety System is designed for the operator’s safety. Do not disconnect or attempt to defeat the purpose of the system. If the system malfunctions, immediately contact your local authorized dealer or the TROY-BILT Technical Service Department for assistance. Do not use the tiller or the PTO power unit until the Forward Interlock Safety System is functioning properly. Always test the system before using the tiller or PTO power unit.

Keep away from rotating tines. Rotating

tines will cause injury.

Cold Weather Operation

When temperatures fall below 40oF, do the following steps to protect your engine and transmission from damage:

1. Refer to the Engine Owner’s Manual for motor oil specifications for cold weather operation. Use winter blend gasoline.

2. Warm up the engine before putting it under a load.

3. Use winter-blend gasoline.

4. Use the correct weight gear oil in PTO

Power Unit transmission.

5. Warm up the transmission gear oil as follows: With engine running, move Wheel Speed Lever (Figure 4-2) to FREEWHEEL (then block wheels so they can’t roll), put Tines/PTO Clutch Lever into DISENGAGE, then squeeze one of the Forward Interlock Levers and shift the Wheels/Tines/PTO Drive Lever to FORWARD.

6. If wheels are frozen to the ground, melt ice with warm water.

CAUTION

DANGER

WARNING

Section 4: Operation

6. When the tiller moves forward, relax

and let the wheels power the tiller along while the tines dig. Walk behind and to one side of the tiller. Walk on the side that is not yet tilled (Figure 4-4). Use a firm grip on the handlebars but keep your arm relaxed.

IMPORTANT: Let the tiller move ahead at its own pace. Do not push it ahead—this reduces operator control and tilling efficiency. Do not push handlebars down in an attempt to dig deeper— this takes weight off the wheels, reduces traction, and causes the tines to try to propel the tiller.

Stopping Forward Motion and Tines

1. To stop forward motion, tap

Wheels/Tines/PTO Drive Lever upward into NEUTRAL. Then release the Forward Interlock Levers. The wheels and tines will stop and the engine will continue running.

2. In an emergency, release all of the control levers. This stops forward motion and shuts-off the engine.

Moving the Tiller in Reverse

IMPORTANT: Do not till while in

REVERSE.

1. Shift the Tines/Wheels/PTO Drive Lever (Figure 4-2) into NEUTRAL and move the Wheel Speed Lever to the SLOW position.

2. Move Tines/PTO Clutch Lever (Figure 4-2) into DISENGAGE position.

3. Verify that the area behind you is clear.

4. Lift up the handlebars until the tines

are off the ground, then shift the Wheels/Tines/PTO Drive Lever all the way up and hold. You do not need to squeeze the Forward Interlock Levers to use reverse.

5. The unit immediately engages in reverse. Periodically check behind you while holding the handlebars up and the Wheels/Tines/PTO Lever in its upper-most position.

Stopping Reverse Motion

Release the Wheels/Tines/PTO Drive Lever– the lever automatically returns to the NEUTRAL position. This stops the wheels immediately. (The Forward Interlock Levers will not stop REVERSE motion.)

To Stop the Engine

Move the engine Throttle Lever to the STOP position. Then, on electric start models, turn key to OFF. Remove the key for safekeeping.

Making Turns

Turning the tiller is easy and just requires practice. First find the balance point between the engine and the tines by lifting up the handlebars (Figure 4-5). Once you find the balance point, then let the powered wheels do the turning as you push sideways on the handlebars in the direction of the turn. Practice the turning maneuver described here in a large open area. Once comfortable turning the tiller, you can then take it to the garden area.

1. At the end of a row, move the Wheels/ Tines/PTO Drive Lever (Figure 4-2) to NEUTRAL position and reduce the engine speed.

2. Move the Tines/PTO Clutch Lever (Figure 4-2) into the DISENGAGE position.

3. Resume forward operation, and lift handlebars until tines are off the ground (Figure 4-5). Find the balance point between the engine and the tines. Then push the handlebars in the direction of the turn.

Be very careful to keep feet and legs away from the tines (which should be disengaged).

Let the powered wheels do the hard work. The inside wheel will pivot in place while the outside wheel drives the tiller around in the direction of the turn.

NOTE: Use REVERSE if necessary to turn in a limited space.

Figure 4-4: Guide tiller with one hand.

Figure 4-3: Moving tiller forward: squeeze one Forward Interlock Lever and then move Wheels/Tines/PTO Drive Lever down to FORWARD.

To Help Avoid Personal Injury or Damage to Equipment:

• Be sure no obstacles are behind you before operating the tiller in REVERSE.

• Disengage the tines, reduce engine speed, and move the Wheel Speed Lever to SLOW position before operating in REVERSE. Avoid using FAST wheel speed until you are familiar with backing the tiller.

Figure 4-5: Turning the tiller.

CAUTION

Section 4: Operation

4. When the turn is complete, shift to

NEUTRAL and lower the handlebars. Move Tines/PTO Clutch Lever back to ENGAGE position and resume forward operation.

Transporting The Tiller Around Your Property

When the engine is running, the tiller’s powered wheels make moving the tiller to and from the garden easy. If the engine is not running set the Wheel Speed Lever to FREEWHEEL position to roll the tiller to another location.

1. Place the Tines/PTO Clutch Lever in DISENGAGE position.

2. Move Depth Regulator Lever down all the way into the Travel setting.

3. If using engine power, move Wheel Speed Lever to either SLOW or FAST, and use the Wheels/Tines/PTO Drive Lever to drive the wheels.

4. If the engine is stopped, move Wheel Speed Lever to FREEWHEEL, and manually push tiller.

Testing the Forward Interlock Safety System

The Forward Interlock Safety System is designed to shut the tiller engine off immediately if you lose control and cannot stop moving FORWARD by shifting the Wheels/Tines/PTO Drive Lever into NEUTRAL. When you release both Forward Interlock Levers, they send ground to the ignition system thereby stopping the engine. Squeezing one or both levers up against the handlebars enables the ignition system; therefore, you must squeeze at least one lever whenever the Wheels/Tines/PTO Drive Lever is engaged in FORWARD.

IMPORTANT: The interlock system also prevents the engine from starting if the Wheels/Tines/PTO Drive Lever is engaged in FORWARD.

How to Check the Interlock System

The Forward Interlock System has an electro-mechanical design, and so is subject to normal wear and possible malfunction. Check the system for proper operation each time prior to using the tiller or PTO power unit.

To test the Forward Interlock System:

1. Move tiller outside to level ground. Remove any obstacles.

2. Check that the Forward Interlock wire harness plug, at the bottom of the handlebars (Figure 4-6), is securely connected to the receptacle on the top, right side of the transmission.

3. Move Wheel Speed Lever (Figure 4-2) to SLOW position and move Tines/ PTO Clutch Lever to DISENGAGE.

4. Start engine as described under Starting and Stopping the Engine, in this section. Set engine throttle lever to SLOW, and let engine warm up.

5. Squeeze and hold just one of the Forward Interlock Levers against the handlebar grip while moving the Wheels/ Tines/ PTO Drive Lever down to FORWARD (Figure 4-3). As the tiller moves forward, release the Forward Interlock Lever briefly. The engine should start to stall out if the interlock system is working properly. If it does start to stall, quickly squeeze the lever up against the handlebar grip, and then return the Wheels/ Tines/ PTO Drive Lever to NEUTRAL. Repeat this test to check that the engine begins to stall out when the other Forward Interlock Lever is released.

6. If the engine does not begin to shut off when either Forward Interlock lever is released, shut the engine off, remove the key (if electric start), and

do not operate the tiller or PTO power unit until the system has been repaired and is functioning properly.

IMPORTANT:

To avoid possible damage to the Forward Interlock Safety system, do not use high-pressure sprays near the wire harness receptacle or neutral plunger assembly.

Loading and Unloading the Tiller

The following provides information on tiller loading, unloading, and requirements before loading and unloading the tiller. Read the following instructions carefully before attempting to load or unload your tiller.

Before Loading or Unloading the Tiller

• Ramps must be strong enough to

support the combined weight of the tiller and handlers. They should provide good traction to prevent slipping; they should have side rails to guide the tiller along the ramps; and they should have a locking device to secure them to the vehicle.

• Handlers should wear sturdy footwear

that will help to prevent slipping.

Figure 4-6: Plug and receptacle of Forward Interlock Safety System must be securely connected.

To help avoid personal injury from revolving tines, always put the Tines/PTO Clutch Lever in DISENGAGE position before transporting, loading, or unloading tiller.

WARNING

DANGER

Section 4: Operation

• Turn the vehicle’s engine off and apply its parking brake.

• Position the loading vehicle so that the

ramp angle is as flat as possible (the less incline to the ramp, the better).

Loading the Tiller

1. Use loading ramps that are strong and

wide enough to safely hold the weight of the tiller and the operator combined— your tiller weighs between 280 and 325 lbs.

2. Move the Tines/PTO Clutch Lever

(Figure 4-2) into DISENGAGE position.

3. Set the Depth Regulator lever (Figure

4-2) to the Travel position.

4. Move Wheel Speed Lever (Figure 4-2)

into SLOW position and reduce the engine throttle speed.

5. Shift the Wheels/Tines/PTO Lever

(Figure 4-2) into FORWARD position and follow the tiller up the ramps (Figure 4-7). Check the wheels as you move the tiller forward. Ensure that they move up the center of each ramp.

6. Prevent tiller from rolling in vehicle.

Leave Wheel Speed Lever in FAST or SLOW position, chock wheels with blocks and tie down the tiller.

Unloading the Tiller

IMPORTANT: Never unload the tiller in

FORWARD drive. The tiller could tip forward and expose you to the tines (which should be disengaged as instructed).

1. Use loading ramps that are strong and

wide enough to safely hold the weight of the tiller and the operator combined— your tiller weighs between 280 and 325 lbs.

2. Move the Tines/PTO Clutch Lever (Figure 4-2) to DISENGAGE position.

3. Set the Depth Regulator Lever (Figure 4-2) to the Travel position.

4. Move Wheel Speed Lever (Figure 4-2) to SLOW position and reduce the engine throttle speed.

IMPORTANT: Look behind you before you back down the ramp to ensure that all is clear. While descending, keep checking for obstacles behind you.

5. Move and hold the Wheels/Tines/PTO Lever into REVERSE drive and back down the ramps (Figure 4-8). Check the wheels as you move the tiller backward. Ensure that they move down the center of each ramp.

Changing Speed Belts

Your tiller has two belt-driven speed ranges – HIGH RANGE and LOW RANGE – you pick one or the other by deciding which set of pulley grooves to move the forward belt into. By moving the belt from one speed range into the other, in combination with the FAST and SLOW wheel speeds, you obtain a choice of four different forward wheel speeds and two different tine speeds.

Changing the belt from LOW range into HIGH range (or back again) is a matter of moving the belt from one set of pulley grooves to a second set of pulley grooves.

This change is done quickly and without tools (Figures 4-9 through 4-13).

When the tiller is moving in REVERSE, the wheels are powered by a rubber reverse disc, not by the belt. Therefore, you have only two reverse speeds SLOW and FAST, as set with the Wheel Speed Lever.

Table 4-1 shows the range of wheel and tine speeds available when using the two belt speed ranges and the FAST and SLOW selections on the Wheel Speed Lever.

Changing Belt From LOW Range to HIGH Range

1. To avoid personal injury, shut off

engine, let all moving parts come to a complete stop, then disconnect spark plug wire from spark plug and move it away from spark plug before making any adjustments. Wait for the engine and muffler to cool down.

2. Move Wheels/Tines/PTO Drive Lever into NEUTRAL.

Figure 4-7: To go up ramps, use

Figure 4-8: To go down ramps, use REVERSE drive.

Figure 4-9: Belt range positions.

To help avoid serious personal injury, stop the engine, remove the ignition key, disconnect spark plug wire and move the wire away from the spark plug, and let engine and muffler cool down before changing belt speeds.

Section 4: Operation

3. Kneel on left side of tiller. To create

belt slack, reach over to right side of the pulleys and push in at the center of the belt with a finger. At the same time, use your left hand to work the belt part-way onto the lower-front transmission pulley groove (Figure 4-10).

4. Go to the other side of the tiller to finish seating the belt onto the pulley groove.

5. Working from the left side of the tiller, work the belt as much as possible onto the top-front engine pulley groove (Figure 4-11).

6. Finish seating the belt from the right side

of the tiller.

IMPORTANT: Proper belt tension is important for good performance. See Section 5,

Drive Belt Maintenance for information on belt maintenance schedule and procedures.

NOTE: If extra belt slack is needed to move the belt, just raise the Wheels/Tines/PTO Drive Lever up into REVERSE. This lowers the engine pulley, and creates more slack.

7. Check both sides of the high range pulley grooves to verify that the belt is properly seated.

Changing Belt From HIGH Range to LOW Range

1. To avoid personal injury, shut off

engine, let all moving parts come to a complete stop, then disconnect spark plug wire from spark plug and move wire away from spark plug before making any adjustments. Let engine and muffler cool.

2. Move the Wheels/Tines/PTO Drive Lever into NEUTRAL.

3. Stand on left side of tiller. Use your right hand to hold the Wheels/Tines/PTO Drive Lever up into REVERSE position. Use your left hand to move the belt off top-front engine pulley groove to top-rear engine pulley groove (Figure 4-12).

4. Go to right side of tiller and finish seating the belt.

5. Still holding the lever up in REVERSE position, and working from the left side of the tiller, move the belt from the lowerfront transmission groove to the lowerrear transmission groove.

6. Go to the right side of the tiller and finish seating the belt (Figure 4-13).

7. Check that the belt is fully seated in the pulley grooves. Check this from both sides of the tiller.

Choosing Wheel and Tine Speeds

Your tiller has four FORWARD wheel/tine speed combinations for handling a variety of tilling tasks and gardening jobs. Experiment with the tine depth, engine speed, and wheel/tine speed and determine the combination that provides the best results. Here are some tips:

1. Advance the throttle lever so the engine has sufficient power.

2. When tilling untilled or hard earth, do not set the Depth Regulator too deep. The tiller will buck and the engine will load down.

3. You will know your settings are ideal when the tines break-up the soil easily, the engine does not labor, and your progress is steady and smooth.

Figure 4-12: High range to low range. Shows moving belt from topfront groove onto top-rear pulley groove.

Figure 4-13: High range to low range. Shows moving belt from lower-front onto lower-rear groove.

Figure 4-11: Low range to high range. Shows moving belt from toprear groove onto top-front groove.

Figure 4-10: Low range to high range. Shows moving belt from lower-rear groove onto lower-front groove.

The HIGH speed belt range position combined with a FAST wheel speed setting propels the tiller at the fastest pace. Reduce the engine throttle speed when starting out to help avoid personal injury or property damage if using this speed combination.
