PREPARATION

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

2. Be sure all controls are released and the Wheel Gear Lever is in ENGAGE 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. 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.

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 (and remove the ignition key on electric start models), disconnect the spark plug wire and prevent it from touching the spark plug, carefully inspect the tiller for any damage, and repair the damage before restarting and operating the tiller.

4. Exercise caution to avoid slipping or falling.

5. If the unit should start to vibrate abnormally, stop the engine (and remove the ignition key on electric start models). 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 (and remove the ignition key on electric start models), 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.

4 Section 1: Safety

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

8. Before cleaning, repairing, or inspecting, stop the engine, remove the ignition key on electric start models, 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. On electric start models, always remove the cable from the negative side (–) of the battery.

9. Always keep the tiller tine hood flap down, unless using the hiller/furrower attachment.

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 set-

tings, working gradually deeper

with each pass. c. Use slower 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 releasing whichever

Clutch Lever is engaged. 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 acces-

sories that are approved by the tiller manufacturer.

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. The battery on electric start model tillers contains sulfuric acid. Avoid contact with skin, eyes, or clothing. Keep out of the reach of children.

4. With the forward clutch cable (N, Figure 2-4) on the inside of handlebar,

position the handlebar ends on the outside of the two mounting tabs (M, Figure 2-3) on the transmission top cover.

NOTE: The curved handlebar height adjustment bracket appears as shown in C, Figure 2-3 for non-electric start units. For electric start units, the bracket is loosened and moved to one side.

5. Loosely attach the handlebars to the mounting tabs with two 3/8-16 x 1" screws (heads of screws go to inside of tabs), 3/8" flat washers and 3/8"-16 lock nuts (O, Figure 2-4).

6. On electric start units, reattach the height adjustment bracket (A, Figure 2-2). Tighten both screws securely. Make sure the handlebar cross-brace (B, Figure 2-3) is under the bracket.

7. Move the handlebars up or down to align the threaded hole in the cross-brace with one of the four slots in the curved height adjustment bracket. Place the keyed washer (E, Figure 2-3) on the flange head height adjustment screw (F) with the raised keys (edges) of the washer facing down.

8. Thread the height adjustment screw (F, Figure 2-3) into the hole in the handlebar cross-brace, making sure that the raised keys on the washer fit into the slot on the height adjustment bracket. Tighten the height adjustment screw securely. Next, securely tighten the two screws and nuts in the ends of the handlebar (M, Figure 2-3).

9. To remove the tiller from its shipping platform, first carefully unwrap the wheel gear cable (with attached lever - see Figure 2-5) from around the chassis. Move the Wheel Gear Lever (G) to the DISENGAGE position--this allows the wheels to rotate freely. Use the handle-

bars to roll the tiller off the platform. NOTE: The Wheel Gear Lever will be installed later in this procedure.

IMPORTANT: Use the DISENGAGE position only when the engine is not running. Before starting the engine, the Wheel Gear Lever must be placed in the ENGAGE position (see Section 3 for details).

STEP 3: ATTACH REVERSE CLUTCH CONTROL CABLE

1. Carefully unwrap the reverse clutch

control cable (H, Figure 2-6) from its shipping position and route it up along the inside edge of the left side handlebar. A knob and large hex nut (I) is installed on the cable.

2. Insert the cable into the slot in the control panel and fit the threaded assembly into the hole in the slot (see Figure 2-

6). Be sure that the flat side of the threaded assembly is aligned with the flat side of the hole. Slide the hex nut (I) up the cable and tighten it securely.

3. Test the function of the reverse clutch control cable by pulling the knob out and releasing it. The knob should return to its neutral position against the tapered bushing. If it doesn’t, contact your local dealer or the factory for technical assistance.

STEP 4: ATTACH FORWARD CLUTCH CONTROL CABLE

1. Remove any fasteners (rubber bands,

tape, etc.) that may secure the Forward Clutch Control levers (J, Figure 2-7) to the handlebar.

2. The forward clutch control cable (with attached spring) is hanging loosely near the right-side wheel. Being careful not to kink or stretch the cable, insert the z-connector (L, Figure 2-8 – end of the spring) into the hole at the end of the forward clutch control linkage (K, Figure 2-7).

3. Attach the cable adjuster (A, Figure 2-9) to the bracket on the right-side handlebar. Use two 1/2" wrenches to loosen the two jam nuts (B) just enough to slide the cable adjuster onto the bracket. Then hand tighten the jam nuts.

4. Check for correct spring/cable tension

as instructed in Section 5, Checking and Adjusting Forward Clutch Belt Tension.

5. When tension is correct, tighten the two jam nuts (B) securely.

STEP 5: CHECK TRANSMISSION GEAR OIL LEVEL

The transmission was filled with gear oil at the factory. However, be sure to check the oil level at this time to make certain it is correct.

IMPORTANT: Do not operate the tiller if the gear oil level is low. Doing so will result in severe damage to the transmission components.

1. With the tiller on level ground, pull the Depth Regulator Lever (R, Figure 2-13) back and then slide it to the second notch from the top. NOTE: If the lever does not move, lift the tine hood flap and look for a plastic tie securing the lever in place. Cut and remove the tie.

2. Remove the oil level check plug (M, Figure 2-10) on the left-side of the transmission. (Due to dried paint on the plug threads, it may require some force to remove the plug the first time.) The gear oil level is correct if oil starts to flow out of the hole as the plug is removed. If so, securely reinstall the plug.

3. If oil does not flow from the check hole, add oil as follows:

NOTE: Do not use automatic transmission fluid or motor oil in the transmission.

(a) Clean area around the fill hole (N, Figure 2-11) and unscrew gear oil fill plug.

(b) If adding only a few ounces of gear oil, use API rated GL-4 or GL-5 gear oil having a viscosity of SAE 140, SAE 85W140 or SAE 80W-90. If refilling an empty transmission, use only GL-4 gear oil having a viscosity of SAE 85W-140 or SAE 140.

(d) Reinstall and tighten securely the gear oil fill plug (M, Figure 2-10).

STEP 6: ADD MOTOR OIL TO ENGINE

The tiller is shipped without oil in the engine crankcase.

IMPORTANT: Do not start the engine without first adding motor oil. Severe engine damage will result if the engine is run without oil.

1. Refer to the separate Engine Owner’s Manual for motor oil specifications and capacities.

2. With the unit on level ground, move the Depth Regulator Lever (R, Figure 2-

13) up or down until the engine is level.

3. Add motor oil as described in the Engine Owner’s Manual.

4. Move the Depth Regulator Lever all the way down until the highest notch is engaged. This places the tines in the “travel” position.

STEP 7: ATTACH WHEEL GEAR LEVER

1. Insert the Wheel Gear Lever (P, Figure

2-12) up through the slot in the control panel that is labeled “WHEEL GEAR.”

2. Insert two #10-32 x 1/2" round head screws down through the “+” marks on the control panel decal and securely attach the wheel gear mounting bracket using two #10 lockwashers and #10-32 nuts.

3. Use a small board to tap the Wheel Gear Lever knob securely onto the lever.

4. Secure the wheel gear cable and the reverse clutch control cable to the leftside handlebar with two plastic ties (S, Figure 2-13) located about two feet apart. Snip off any excess tie length with scissors.

STEP 8: CHECK AIR PRESSURE IN TIRES

Use a tire pressure gauge to check the air pressure in both tires. Deflate or inflate both tires equally to 15-to-20 PSI (pounds per square inch). Be sure that both tires are inflated equally or the unit will pull to one side.

STEP 9: CHECK HARDWARE FOR TIGHTNESS

Inspect the hardware on the unit and tighten any loose screws, bolts and nuts.

IMPORTANT:

• This completes assembly for recoil start tillers. Read the rest of this Manual, and the separate Engine Owner’s Manual, before operating the tiller.

• Electric start models--continue with the Assembly Steps.

CAUTION

Features and Controls

Section

Before operating your machine, carefully read and understand all safety, controls and 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.

INTRODUCTION

This Section describes the location and function of the controls on your tiller. Refer to the following section “Operation” for detailed operating instructions.

Practice using these controls, with the engine shut off, until you understand the operation of the controls and feel confident with them.

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

WHEEL GEAR LEVER

This lever (A, Figure 3-1) has two positions: ENGAGE and DISENGAGE.

In the ENGAGE position, the wheels will start turning when either the Forward Clutch Control or the Reverse Clutch Control is engaged (the tines will also start turning when either clutch is engaged).

The DISENGAGE position places the wheels in the freewheeling mode to allow the unit to be moved without the engine running. Use the DISENGAGE position only when the engine is not running. See “DANGER” statement that follows.

To shift to ENGAGE, gently (do not force) move the lever forward while also rolling the tiller a few inches forward or backward. Moving the tiller helps to align the shift mechanism with the transmission wheel drive gears.

To shift to DISENGAGE (freewheel), move the lever rearward, without rolling the tiller. The wheels will roll freely when the lever is properly set in the DISENGAGE position.

FORWARD CLUTCH CONTROL

The two interconnected levers (B, Figure 3-1) control the engagement of forward drive to the wheels and tines.

To Operate the Forward Clutch Control:

Before engaging the Forward Clutch Control, put the Wheel Gear Lever in the ENGAGE position (see “WARNING” below).

2. Pull up and hold one or both of the levers against the handlebar grips to engage the wheels and tines.

3. Release BOTH levers to disengage (stop) the wheels and tines. All forward motion will stop (the engine will continue to run).

Figure 3-1: Controls located on handlebar.

Never place the Wheel Gear Lever in DISENGAGE (Freewheel) when the engine is running.

Having the Wheel Gear Lever in DISENGAGE and then engaging the tines/wheels with either the Forward Clutch Control or the Reverse Clutch Control could allow the tines to propel the tiller rapidly forward or backward.

Failure to follow this instruction could result in personal injury or property damage.

Never engage the wheels and tines with the Forward Clutch Control or the Reverse Clutch Control unless the Wheel Gear Lever is in ENGAGE.

Engaging the Forward Clutch Control or the Reverse Clutch Control when the wheels are not engaged could allow the tines to rapidly propel the tiller forward or backward.

Failure to follow this warning could result in personal injury or property damage.

WARNING

DANGER

WARNING

10 Section 3: Features and Controls

REVERSE CLUTCH CONTROL

The Reverse Clutch Control (C, Figure 3-1) controls the engagement of reverse drive to the wheels and tines. The revers-

ing feature is used for maneuvering the tiller only – never engage the tines in the ground while going in the reverse direction.

To Operate the Reverse Clutch Control:

1. Put the Wheel Gear Lever in the

ENGAGE position (see the “WARNING” statement on previous page).

2. Stop all tiller motion by releasing the Forward Clutch Control levers.

3. Lift up the handlebars until the tines clear the ground, look behind you to avoid any obstacles, and then pull the Reverse Clutch Control knob out. The tines and wheels will rotate in a reverse direction.

4. Release the Reverse Clutch Control knob to disengage (stop) the wheels and tines. All reverse motion will stop (the engine will continue to run).

DEPTH REGULATOR

The Depth Regulator lever (D, Figure 3-2) controls the tilling depth of the tines. Pull the lever straight back and slide it up or down to engage the notched height settings.

The highest notch (lever all the way down) raises the tines approximately 1-1/2 inches off the ground. This “travel” position allows the tiller to be moved without the tines digging into the ground.

Moving the lever up increases the tilling depth. The lowest notch allows a tilling depth of approximately six to eight inches, depending on soil conditions.

For best results, always begin tilling at a very shallow depth setting and gradually increase the tilling depth. Complete

details on using the Depth Regulator are found in the “Operation” Section of this manual.

The handlebar height is adjustable to four different settings. Set the handlebar height to a comfortable setting, but keep in mind that the handlebars will be lower when the tines are engaged in the soil.

To Adjust the Handlebar Height:

1. Stop the engine, wait for all parts to

stop moving and then disconnect the spark plug wire. Remove the ignition key on electric start models.

2. Loosen the two screws at the lower ends of the handlebar.

3. Loosen the height adjustment screw (E, Figure 3-3) and pull the keyed washer (F) free of the slots in the curved height adjustment bracket.

4. Move the handlebars to the new slot setting and insert the raised keys on the keyed washer into the slot. Tighten the height adjustment screw securely.

5. Retighten the two screws at the ends of the handlebar.

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. The following two controls are used when stopping or starting the engine.

IMPORTANT: The control for stopping the recoil start engine is located on the engine.

ENGINE THROTTLE CONTROL LEVER

The Engine Throttle Control Lever (located on engine--see Figure 4-1) is used to regulate the engine speed. On the recoil start model only, it is also used to stop the engine (on the electric start model, the electric start keyswitch is used to stop the engine). The throttle settings are shown below.

IMPORTANT: See “Starting and Stopping the Engine” in the “Operation” Section for detailed engine starting and stopping instructions.

FAST - Use for most tilling and cultivating projects.

SLOW - Use when idling engine or when slower tilling and cultivating speeds are needed.

STOP - Stops the engine (on recoil start models only).

• Use extreme caution when reversing or pulling the machine towards you. Look behind to avoid obstacles.

• Never attempt to till in reverse.

Failure to follow this warning could result in personal injury or property damage.

• Do not attempt to till too deeply too quickly. Gradually work down to deeper tilling depths.

• Place the Depth Regulator Lever in the “travel” position before starting the

engine. This position prevents the tines from touching the ground until you are ready to begin tilling.

Failure to follow this warning could result in personal injury or property damage.

To Start the Electric Start Engine With the Recoil Starter Rope

If necessary, the electric start engine can be started with the recoil starter rope by following the steps below:

1. If the battery is not “dead” or damaged, leave it connected to the tiller so it will be recharged during engine operation. Make sure the battery cells are filled to the UPPER LEVEL line with electrolyte.

2. If the battery is “dead” or damaged, remove it (refer to “Battery Removal and Installation” in Section 5) and have it tested. Before starting engine, cover the terminal on the loose end of the positive (+) cable with the insulated boot and secure it in place with electrical tape to prevent electrical sparks.

3. Put the ignition key in the “RUN” position and then follow Steps 1-8 of “Starting the Engine.”

STOPPING THE ENGINE

1. To stop the wheels and tines, release

the Forward Clutch Control levers or the Reverse Clutch Control knob (whichever control is engaged).

2. To stop the engine on the recoil start model, move the Engine Throttle Control Lever to the “STOP” position.

3. To stop the engine on an electric start model, move the ignition key to “OFF”.

IMPORTANT: After stopping an electric start engine, remove the ignition key from the switch to reduce the possibility of unauthorized starting of the engine.

OPERATING THE TILLER

The following pages provide guidelines to 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” tiller with forward rotating tines. It operates completely differently from CRT (Counter Rotating Tines) tillers or from low-cost front tine tillers.

1. Follow the “Pre-Start Checklist” on the previous page. Be sure that the Wheel Gear Lever is in the ENGAGE position.

2. Put the Depth Regulator Lever in the “travel” position (lever all the way down) so that the tines are clear of the ground. Use this position when practicing with your tiller or when moving to or from the garden. When you are ready to begin tilling, you must move the Depth Regulator Lever to the desired depth setting (see “Tilling Tips & Techniques”).

3. Start the engine and allow it to warm up. When warm, put Engine Throttle Control Lever in “FAST” speed setting.

4. For forward motion of the wheels and tines:

(a) Pull one or both of the Forward

Clutch Control Levers up and hold them against the handlebars. To stop forward motion of the wheels and tines, release the levers.

Keep away from rotating tines. Rotating

tines will cause injury.

WARNING

Section 4: Operation 13

(b) As the tiller moves forward, relax

and let the wheels pull the unit along while the tines dig. Walk behind and a little to one side of the tiller. Use a light but secure grip with one hand on the handlebars, but keep your arm loose. See Figure 4-2. Let the tiller move ahead at its own pace and do not push down on the handlebars to try and force the tiller to dig deeper – this takes weight off the wheels, reduces traction, and causes the tines to try and propel the tiller.

5. For reverse motion of the wheels and tines:

(a) Look behind and exercise caution

when operating in reverse. Do not

till while in reverse.

(b) Stop all forward motion before

reversing. Lift the handlebars with one hand until the tines are off the ground and then pull the Reverse Clutch Control knob out to engage reverse motion (see Figure 4-3). To stop reverse motion, let go of the Reverse Clutch Control knob.

6. To Turn the Tiller Around:

(a) Practice turning the tiller in a level,

open area. Be very careful to keep your feet and legs away from the tines.

(b) To make a turn, reduce the engine

speed and then lift the handlebars until the engine and tines are balanced over the wheels (Figure 4-4).

ways on the handlebar to move the tiller in the direction of the turn (Figure 4-5). After completing the turn, slowly lower the tines into the soil and increase the engine speed.

Stopping the Tiller and Engine

1. To stop the wheels and tines, release

the Forward Clutch Control levers or the Reverse Clutch Control knob (whichever is engaged).

2. To stop the recoil start engine, move the Engine Throttle Control Lever to “STOP”. On electric start models, turn the ignition keyswitch to “OFF” to stop the engine.

Turning the Tiller Around

Figure 4-3: Raise tines off ground and look behind when moving in reverse.

Figure 4-4: To begin turn, reduce engine speed and lift handlebars until engine and tines are balanced over wheels.

Figure 4-5: With tiller balanced over wheels (and tines out of the ground), push handlebars sideways to turn tiller.

Do not push down on the handlebars to try to make the tiller till more deeply. This prevents the wheels from holding the tiller back and can allow the tines to rapidly propel the tiller forward, which could result in loss of control, property damage, or personal injury.

Before tilling, contact your telephone or utilities company and inquire if underground equipment or lines are used in your area. Their representative will be glad to answer your questions and tell you if any of their equipment or lines are buried underground on your property.

Tilling Tips

Techniques

Let the tiller do the work

• While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making footprints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand.

• Avoid pushing down on the handlebars in an attempt to force the tiller to dig deeper. Doing so takes the weight off the powered wheels, causing them to lose traction. Without the wheels helping to hold the tiller back, the tines will attempt to propel the tiller – often causing the tiller to skip rapidly across the ground. (Sometimes, slight downward pressure on the handlebars will help get through a particularly tough section of sod or unbroken ground, but in most cases this won’t be necessary at all.)

Tilling depths

• Avoid trying to dig too deeply too quickly, especially when busting sod or when tilling soil that hasn’t been tilled for some time. Use shallow depth regulator settings (only an inch or two deep) for the first passes through the garden area. With each succeeding pass, adjust the depth regulator to dig another inch or two deeper. (Watering the garden area a few days prior to tilling will make tilling easier, as will letting the newly worked soil set for a day or two before making a final, deep tilling pass.)

• When cultivating (breaking up the surface soil around plants to help destroy weeds), use very shallow depth settings to prevent injury to plants whose roots often grow close to the surface. If needed, lift up on the handlebars slightly to prevent the tines from digging too deeply. (Cultivating on a regular basis not only eliminates weeds, it also loosens and aerates the soil for better moisture absorption and faster plant growth.)

Avoid tilling soggy, wet soil

Tilling wet soil often results in large, hard clumps of soil that can interfere with planting. If time permits, wait a day or two after heavy rains to allow the soil to dry before tilling. Test soil by squeezing it into a ball. If it compresses too easily, it is too wet to till.

Avoid making footprints

When possible, walk on the untilled side of the unit to avoid making footprints in the freshly tilled soil. Footprints cause soil compaction that can hamper root penetration and contribute to soil erosion. They can also “plant” unwanted weed seeds back into the freshly tilled ground.

Choosing correct wheel and tine speeds

With experience, you will find the “just right” tilling depth and tilling speed combination that is best for your garden.

Set the Engine Throttle Control Lever to a speed to give the engine adequate power and yet allow it to operate at the slowest possible speed...at least until you have achieved the maximum tilling depth you desire. Faster engine speeds may be desirable when making final passes through the seedbed or when cultivating. Selection of the correct engine speed, in relation to the tilling depth, will ensure a sufficient power level to do the job without causing the engine to labor.

Suggested tilling patterns

• When preparing a seedbed, go over the same path twice in the first row, then overlap one-half the tiller width on the rest of the passes (see Figure 4-6). When finished in one direction, make a second pass at a right angle as shown in Figure 4-7. Overlap each pass for best results (in very hard ground it may take three or four passes to thoroughly pulverize the soil).

• If the garden size will not permit lengthwise and then crosswise tilling, then overlap the first passes by onehalf a tiller width, followed by successive passes at one-quarter width (see Figure 4-8).

• With planning, you can allow enough room between rows to cultivate (see Figure 4-9). Leave room for the hood width, plus enough extra room for future plant growth.

Section 4: Operation 15

Tilling Tips & Techniques

Clearing the tines

The tines have a self-clearing action which eliminates most tangling of debris in the tines. However, occasionally dry grass, stringy stalks or tough vines may become tangled. Follow these procedures to help avoid tangling and to clean the tines, if necessary.

• To reduce tangling, set the depth regulator deep enough to get maximum “chopping” action as the tines chop the material against the ground. Also, try to till under crop residues or cover crops while they are green, moist and tender.

• While power composting, try swaying the handlebars from side to side (about 6" to 12"). This “fishtailing” action often clears the tines of debris.

• If tangling occurs, lift the tines out of the soil and run the tiller in reverse for a few feet. This reversing action should unwind a good deal of debris.

• If reversing the tiller doesn’t clear the debris, it may be necessary to remove the debris by hand (a pocket knife will help you to cut away the material).

Tilling on slopes

If you must garden on a moderate slope, please follow two very important guidelines:

1. Till only on moderate slopes, never on steep ground where footing is difficult (review safety rules in the “Safety” Section of this Manual).

2. We recommend tilling up and down slopes rather than terracing. Tilling vertically on a slope allows maximum planting area and also leaves room for cultivating.

IMPORTANT: When tilling on slopes, be sure the correct oil level is maintained in the engine (check every one-half hour of operation). The incline of the slope will cause the oil to slant away from its normal level and this can starve engine parts of required lubrication. Keep the engine oil level at the full point at all times!

A. Tilling up and down slopes:

• To keep soil erosion to a minimum, be

sure to add enough organic matter to the soil so that it has good moistureholding texture and try to avoid leaving footprints or wheel marks.

• When tilling vertically, try to make the

first pass uphill as the tiller digs more deeply going uphill than it does downhill. In soft soil or weeds, you may have to lift the handlebars slightly while going uphill. When going downhill, overlap the first pass by about one-half the width of the tiller.

B. Terrace Gardening:

• When a slope is too steep or too short

for vertical tilling, it may be necessary to till across the slope and create terraced rows. Terraces are rows that are cut into the side of a slope, creating a narrow, but flat area on which to plant.

• On a long slope, you can make several terraces, one below the other.

• Terraces should be only 2-to-3 feet wide. Digging too far into the side of the slope will expose poor subsoil that is unproductive for plants.

• To create a terrace, start at the top of the slope and work down. Go back and forth across the first row as shown in Figure 4-10.

• Each succeeding lower terrace is started by walking below the terrace you’re preparing. For added stability of the tiller, always keep the uphill wheel in the soft, newly tilled soil. Do not till the last 12" or more of the downhill outside edge of each terrace. This untilled strip helps prevents the terraces from breaking apart and washing downhill. It also provides a walking path between rows.

C. Tilling across slopes without using terraces:

• If vertical or terracing gardening aren’t practical for you, then you can till laterally across a slope. We don’t really recommend this method as it can create unsure footing and invites soil erosion.

• As in terrace gardening, start at the top of the slope and overlap the first pass by half the width of the tiller. For added stability of the tiller, always keep the uphill wheel in the soft, newly tilled soil.

Figure 4-10

Before clearing the tines by hand, stop the engine, allow all moving parts to stop and disconnect the spark plug wire. Remove the ignition key on electric start models.

Failure to follow this warning could result in personal injury.

POWER COMPOSTING

Power composting simply means tilling under and burying in the soil all manner of organic matter such as crop residues, leaves, grass clippings and cover crops. This material will decompose during the non-growing season and add important natural nutrients to the soil.

The first place to begin is with crop residues such as leftover vines, stalks, stems and roots. Power compost these crop residues as soon as they finish bearing. The sooner this is done, the better, as tender green matter is easier to till under. Use the deepest depth regulator setting possible without causing the engine to labor or the tiller to jump ahead.

Standing cornstalks of reasonable height can be power composted. Pushing over (but not uprooting) cornstalks will often make it easier for your tiller to chop up the stalks. Keep the tines clear of excessive tangling by “fishtailing” or frequently using reverse. Make several passes, then return a few days later to finish off any remaining stubble.

After tilling under crop residues, add more organic matter such as leaves, grass clippings and even kitchen scraps. When tilled into the soil, this organic matter will decompose and add even more important nutrients to the soil.

After power composting, you may want to plant a “green manure” cover crop to protect the soil during the off-season. You simply grow a crop of clover, alfalfa, buckwheat, peas, beans, rye grass, grain, or kale and then till it into the soil prior to the planting season.

LOADING AND UNLOADING THE TILLER

• Before loading or unloading, stop the engine, wait for all parts to stop moving, disconnect the spark plug wire and let the engine and muffler cool. Remove the ignition key on electric start models.

• The tiller is too heavy (over 170 lbs., depending on model) and bulky to lift safely by one person. Two or more people should share the load.

• Use sturdy ramps and manually (engine shut off) roll the tiller into and out of the vehicle. Two or more people are needed to do this.

• Ramps must be strong enough to support the combined weight of the tiller and any handlers. The ramps 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.

• The handlers should wear sturdy footwear that will help to prevent slipping.

• Position the loading vehicle so that the ramp angle is as flat as possible (the less incline to the ramp, the better). Turn the vehicle’s engine off and apply its parking brake.

• When going up ramps, stand in the normal operating position and push the tiller ahead of you. Have a person at each side to turn the wheels.

• When going down ramps, walk backward with the tiller following you. Keep alert for any obstacles behind you. Position a person at each wheel to control the speed of the tiller. Never go down ramps tiller-first, as the tiller could tip forward.

• Use wooden blocks to place on the downhill side of the wheels if you need to stop the tiller from rolling down the ramp. Also, use the blocks to temporarily keep the tiller in place on the ramps (if necessary), and to chock the wheels in place after the tiller is in the vehicle.

• When the tiller is in the vehicle, prevent it from rolling by engaging the wheels in the wheel drive position (put Wheel Gear Lever in ENGAGE). Chock the wheels with blocks and securely tie the tiller down.

When power composting, do not keep the Depth Regulator Lever at a deep setting if the tiller jumps or bucks.

If jumping or bucking occurs, move the Depth Regulator Lever down to one of the shallower settings and then slowly increase the tilling depth on later passes.

Failure to follow this warning could result in personal injury.

Loading and unloading the tiller into a vehicle is potentially hazardous and we don’t recommend doing so unless absolutely necessary, as this could result in personal injury or property damage.

However, if you must load or unload the tiller, follow the guidelines given next.

WARNING

Maintenance

Section

TILLER LUBRICATION

Proper lubrication of the tiller is an essential part of your maintenance program. After every 10 operating hours, oil or grease the lubrication points shown in Figure 5-1 as described below.

Use a good quality lubricating oil (#30 weight engine oil is suitable) and a good quality general purpose grease (grease that has a metal lubricant is preferred, if available).

• Remove wheels, clean wheel shaft (A,

Figure 5-1) and apply thin coating of grease to shaft.

• Grease back, front and sides of depth

regulator lever (B, Figure 5-1).

• Remove tines, clean tine shafts (C,

Figure 5-1) and inspect for rust, rough spots or burrs (especially around holes). File or sand smooth and coat ends of shaft with grease.

• Oil the threads on the handlebar height

adjustment screw (D, Figure 5-1).

• Oil the threads on the handlebar attach-

ing screws (E, Figure 5-1).

CHECK HARDWARE

At least every 10 operating hours, check the unit for loose or missing hardware (screws, bolts, nuts, hairpin cotters, etc.). Loose or missing hardware can lead to equipment failure, poor performance or oil leaks.

Be sure to check the three end cap mounting screws located at the rear of the transmission (Figure 5-2). Lift the tine flap to service those screws.

CHECK TIRE PRESSURE

Check the air pressure in both tires. Deflate or inflate both tires evenly to 15to-20 PSI (pounds per square inch). Be sure that both tires have the same air pressure or the unit will tend to pull to one side.

Figure 5-1: Lubrication points.

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, disconnect spark plug wire and move wire away from spark plug. Remove ignition key on electric start models.

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

WARNING

18 Section 5: Maintenance

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

CHECK FOR OIL LEAKS

Before each use, check your tiller for signs of an oil leak – usually a dirty, oily accumulation either on the unit or on the floor where it has been parked.

A little seepage around a cover or oil seal is usually not a cause for alarm. However, if the oil drips overnight then immediate attention is needed as ignoring a leak can result in severe transmission damage.

If a cover is leaking, try tightening any loose screws or bolts. If the fasteners are tight, a new gasket or oil seal may be required. If the leak is from around a shaft and oil seal, the oil seal probably needs to be replaced. See your authorized dealer or contact the factory for service or advice.

IMPORTANT: Never operate the tiller if the transmission is low on oil. Check the oil level after every 30 hours of operation and whenever there is any oil leakage.

TRANSMISSION GEAR OIL SERVICE

Check the transmission gear oil level after every 30 hours of operation or whenever you notice any oil leak. Operating the tiller when the transmission is low on oil can result in severe damage.

A. To Check Transmission Gear Oil Level:

1. Check the gear oil level when the trans-

mission is cool. Gear oil will expand in warm operating temperatures and this expansion will provide an incorrect oil level reading.

2. To check the gear oil level (and to add oil, if necessary), refer to “STEP 5: Check Gear Oil Level in Transmission” in Section 2 of this manual.

B. To Drain and Refill the Transmission:

The transmission gear oil does not need to be changed unless it has been contaminated with dirt, sand or metal particles.

1. Prop up the left side of the unit so that it will be securely supported when the left side wheel is removed. Remove the left side wheel by removing the wheel mounting hardware.

2. Unscrew the plastic gear oil fill plug from the top of the transmission.

3. Place a clean pan below the transmission drain plug (see Figure 5-3) and remove the drain plug. The oil will start flowing out of the drain hole (it may flow slowly, especially in cold temperatures).

4. Remove the transmission gear oil level check plug that is located a few inches above the left side wheel shaft.

5. When the oil stops flowing, tilt the transmission forward to drain oil from the rear of the transmission.

6. After draining the oil, clean the threads of the drain plug, apply a non-hardening removable gasket sealant to the threads, and securely reinstall the drain plug.

7. Using a clean funnel, slowly add SAE 140 or SAE 85W-140 weight gear oil (with an API rating of GL-4 only) to the transmission. The transmission holds approximately 3-1/4 pints (52-54 ounces). Tilt the tiller slightly backwards to make sure the gear oil reaches the rear (tine) end of the transmission. Stop adding gear oil when it begins to flow from the oil level check hole on the side of the transmission.

8. Securely reinstall the oil level check plug.

9. Securely reinstall the gear oil fill plug on top of the transmission.

10. Reinstall the wheel and remove the prop.

WARNING

Section 5: Maintenance 19

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

ENGINE OIL SERVICE

Check the engine oil level before starting the engine each day and check it after each 5 hours of continuous operation. Running the engine when it is low on oil will quickly ruin the engine.

It is recommended that you change the motor oil after every 10 hours of operation and even sooner when operating in extremely dirty or dusty conditions. Refer to the separate Engine Owner’s Manual for detailed service instructions.

A. To Check the Engine Oil Level:

1. Move the tiller to a level area and shut

off the engine.

2. Level the engine by moving the Depth Regulator Lever up or down as needed.

3. Clean the area around the oil dipstick or oil fill tube to prevent dirt from falling into the crankcase.

4. On engines with an oil fill tube, remove the filler cap, add oil (if required) until it reaches the top of the tube and reinstall the filler cap.

5. On engines with a dipstick, remove it, wipe it clean, and reinstall it finger-tight. Remove the dipstick and check the reading. Add oil (if required) to bring the level to the FULL mark. Do not overfill.

B. To Change the Engine Oil:

Change the engine oil as instructed in the separate Engine Owner’s Manual.

AIR CLEANER SERVICE

The engine air cleaner filters dirt and dust out of the air before it enters the carburetor. Operating the engine with a dirty, clogged air filter can cause poor performance and damage to the engine. Never operate the engine without the air cleaner installed. Inspect and service the air cleaner more often if operating in very dusty or dirty conditions.

Service the air cleaner as instructed in the separate Engine Owner’s Manual.

SPARK PLUG SERVICE

Inspect and clean or replace the spark plug after every 100 operating hours or annually. Clean the plug and set the gap as described in the separate Engine Owner’s Manual.

In some areas, local law requires using resistor spark plugs to suppress ignition signals. If the engine was originally equipped with a resistor spark plug, use the same type for replacement.

SPARK ARRESTER SCREEN SERVICE

If the engine muffler is equipped with a spark arrester screen, remove and clean it according to the time intervals and instructions in the separate Engine

Owner’s Manual.

ENGINE CLEANING

The engine must be kept clean to assure smooth operation and to prevent damage from overheating. Refer to the separate Engine Owner’s Manual for specific repair and cleaning instructions. All inspections and services must be done with the engine shut off and cool to the touch.

CARBURETOR/GOVERNOR CONTROL ADJUSTMENTS

The carburetor was adjusted at the factory for best operating speed. Refer to the separate Engine Owner’s Manual for any adjustment information or see your authorized engine service dealer.

The governor controls the maximum safe operating speed and protects the engine and all moving parts from damage caused by overspeeding. Do not tamper with the engine governor settings. Seek authorized service if a problem exists.

THROTTLE CONTROL ADJUSTMENT

If the engine does not respond to various throttle lever settings, refer to the separate Engine Owner’s Manual for service information or contact your local authorized engine service dealer.

Figure 5-3: Remove drain plug to drain transmission gear oil (also remove oil fill plug and oil level check plug).

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.

When the Wheel Gear Lever is in DISENGAGE, the wheels will roll freely (freewheel). The wheels should not roll freely when the lever is in ENGAGE. If the wheels roll freely when the Wheel Gear Lever is in ENGAGE, the wheel gear cable needs to be adjusted as described below.

1. With the engine shut off and the spark plug wire disconnected, put the Wheel Gear Lever in ENGAGE.

2. Loosen the top adjustment nut (A, Figure 5-4) on the wheel gear cable bracket that is located on the left side rear of the transmission.

3. Push the wheel gear cable (B) down and roll the tiller slightly forward or backward until the eccentric lever (C) engages (locks) the wheels. Hold the cable in that position and tighten the top (A) and bottom (D) adjustment nuts.

4. Move the Wheel Gear Lever to ENGAGE and DISENGAGE several times to check the adjustment. The wheels should not roll when the lever is in ENGAGE, but they should roll when the lever is in DISENGAGE. Readjust the cable as required.

OFF SEASON STORAGE

When the tiller won’t be used for extended periods, prepare it for storage as follows:

1. Clean the tiller and engine.

2. Do routine tiller lubrication and check

for loose parts and hardware.

3. Protect the engine and perform recommended engine maintenance by following the engine storage instructions found in the separate Engine Owner’s Manual. NOTE: Be sure to protect the fuel lines, carburetor and fuel tank from gum deposits by removing fuel or by treating fuel with a fuel stabilizer (follow engine manufacturer’s recommendations).

4. On electric start units, follow “Battery Storage” instructions in this Section.

5. Store unit in a clean, dry area.

6. Never store the tiller with fuel in the

fuel tank in an enclosed area where gas fumes could reach an open flame or spark, or where ignition sources are present (space heaters, hot water heaters, furnaces, etc.).

BOLO TINES

The tines will wear with use and should be inspected at the beginning of each tilling season and after every 30 operating hours. Tines can be replaced individually or as a complete set. Never inspect or service the tines unless the engine is stopped, the spark plug wire is disconnected, and the ignition key is removed on electric start models.

A. Tine Inspection:

With use, the tines will become shorter, narrower and pointed (Figure 5-5). Badly worn tines will result in a loss of tilling depth and reduced effectiveness when chopping up and turning under organic matter. Use Figure 5-5 as a guide to when the tines should be replaced.

B. Removing a Single Tine:

1. Remove the two screws and nuts that

attach a single tine to the tine holder (Figure 5-6). If needed, use penetrating oil to help free the nuts.

2. When installing a single tine, be sure to position it so that its cutting edge will

enter the soil first as the tiller moves forward.

C. Removing a Tine Assembly:

1. If removing both tine assemblies, mark

them “left” and “right” before removal. Doing so will help ensure that the assemblies are reinstalled on the correct sides of the tiller.

2. Remove the screw and locknut that secure the tine assembly to the tine shaft (Photo 5-7). Pull the tine assembly off the shaft (if necessary, use a rubber mallet to tap the tine assembly outward).

3. Before reinstalling the tine assembly, inspect the tine shaft for rust, rough spots or burrs and file or sand as needed. Apply a thin coat of grease to the shaft.

4. Install each tine assembly so that the cutting edge of the tines will enter the soil first when the tiller moves forward.

Secure the tine assembly to the tine shaft using the screw and locknut previously removed. Tighten securely.

WARNING

Section 5: Maintenance 21

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

CHECKING AND ADJUSTING TENSION ON CLUTCH BELTS

Maintaining correct belt tension is important to good tilling performance and long belt life. A loose belt will slip on the engine and transmission pulleys and cause the tines and wheels to slow down – or stop – even though the engine is running at full speed. A loose belt will also result in premature belt wear.

While checking belt tension, also check for cracks, cuts or frayed edges. A belt in poor condition should be replaced.

Tension on a new forward clutch belt (C, Figure 5-8) should be checked after the

first two (2) hours of operation and after every ten (10) hours of operation.

The reverse clutch belt (D, Figure 5-9), because it is used more sparingly, may not require tension adjustment until a significant number of operating hours has passed. A tension adjustment is required only if there is little or no reverse movement when the Reverse Clutch Control knob is pulled out.

Checking and Adjusting Forward Clutch Belt Tension

It is important to maintain correct tension on the forward clutch belt. A loose belt will cause the tines and wheels to slow down – or stop completely – even though the engine is running at full speed.

A loose belt will also result in premature belt wear.

• Check belt tension after the first two hours of break-in operation and after every 10 operating hours.

• At the end of each tilling season, check the belt for cracks, cuts or frayed edges. A belt in poor condition should be replaced.

WARNING

22 Section 5: Maintenance

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

Checking Forward Belt Tension

1. Before checking, shut off engine, allow the engine and muffler to cool down, disconnect the spark plug wire, remove the ignition key on electric start models.

2. The coiled part of the forward clutch spring (E, Figure 5-10) measures 2" in length when the Forward Clutch Control levers are not pulled up. Pull either Forward Clutch Control Lever up against the handlebar and measure the length of the coil on the forward clutch spring. Tension is correct if the length of the extended coil is 2-1/2" (see Figure 5-11). The forward clutch control cable needs adjustment if the extended length of the coil is not 2-1/2". See Adjusting the Forward Clutch Belt for a procedure.

Adjusting the Forward Clutch Cable

Do this procedure if the forward clutch spring measurement is not correct (see Checking Forward Belt Tension).

1. Before adjusting the belt, shut off engine, allow the engine and muffler to cool down, disconnect the spark plug wire, and remove the ignition key on electric start models.

2. Belt adjustments are done with the

forward clutch cable adjuster (F, Figure 5-

10). Use two 1/2", open-end wrenches to loosen the two jam nuts (A, Figure 5-12) a few turns.

3. Move cable adjuster (B, Figure 5-12) downward for more belt tension (see Figure 5-12).

4. Hand tighten the jam nuts and pull the Forward Clutch Control levers up against the handlebar. Measure the spring coil (Figure 5-11). The extended length of the coil should be 2-1/2". Repeat this procedure until the extended spring length is correct.

5. Tighten both jam nuts securely.

Checking and Adjusting Reverse Clutch Belt Tension

Checking Reverse Clutch Belt Tension

The reverse clutch belt (D, Figure 5-9) needs adjustment if the belt slips in reverse or if there is no reverse. See Adjusting Reverse Clutch Belt below.

Adjusting Reverse Clutch Belt

1. Before adjusting the belt, shut off engine, allow the engine and muffler to cool down, disconnect the spark plug wire, and remove the ignition key on electric start models.

2. Remove the two nuts (C, Figure 5-13) and remove the belt cover.

3. Reverse belt tension adjustments are done with the reverse clutch cable adjuster located on the left side of the machine near the engine (D, Figure 5-14). Use two 1/2" open-end wrenches to loosen the two adjuster jam nuts (E) a few turns.

4. Move the cable adjuster (D, Figure 5-14) away from the pulleys to increase belt tension.

5. Tighten both jam nuts securely.

6. Reinstall the belt cover.

7. Move the unit to an open area and test

the reverse operation. Repeat this procedure if the unit does not respond when the reverse clutch is engaged.

FORWARD CLUTCH BELT REMOVAL AND REPLACEMENT

The forward clutch belt (K, Figure 5-15) engages the engine pulley (I) and the transmission pulley (J) when either Forward Clutch Control Lever is pulled up against the handlebar. This tightens the forward clutch cable (G) which causes the forward clutch idler pulley (H) to apply pressure to the forward clutch belt. This causes the pulleys to turn for Forward movement.

WARNING

CAUTION

Section 5: Maintenance 23

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

Removing Forward Clutch Belt

1. Stop engine, allow it to cool and dis-

connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2. Remove the two nuts (C, Figure 5-13) and remove the belt cover.

3. Move the reverse clutch belt (B, Figure 5-16) out of the way. You do not need to completely remove the belt. Press the reverse idler pulley inward for slack and then slip the bottom half of the belt completely off the transmission pulley (A, Figure 5-16). Pull the bottom half of the belt out of the housing and let it hang off the outside of the unit (B).

4. Disconnect the forward clutch cable from the forward clutch idler arm bracket

(Figure 5-17). Note the hole from which you disconnect the cable. It is important that you reconnect the cable to the same hole.

5. Slide the belt off the engine pulley (C, Figure 5-18), away from engine, out from under the belt guide (D), and completely off the pulley.

6. Slip the belt off the front of the transmission pulley (F, Figure 5-19).

7. Work the belt out from between the pulley and the frame, around the transmission cover spring, then up and out of the machine.

Installing Forward Clutch Belt

1. Stop engine, allow it to cool and dis-

connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2. Remove the old forward clutch belt as described in Removing Forward Clutch Belt.

3. From the front of tiller, insert the forward clutch belt in between the bottom of the engine drive pulley (I) and the top of transmission pulley (K, Figure 5-20).

4. Insert the bottom half of belt into the smaller, rear-most groove of the transmission pulley (F, Figure 5-19). Now slip the top half of belt under the belt guide (D, Figure 5-18) and onto the large groove of engine drive pulley (L, Figure 5-19).

5. Reconnect the forward clutch cable to the correct hole in the idler arm bracket, as shown in Figure 5-17.

NOTE: Be sure to run the reverse clutch cable on the pulley side of the cover support brackets (G, Figure 5-21).

IMPORTANT: Belt must be installed on the inside of the belt guide (H, Figure 5-21).

6. Reinstall the reverse clutch belt. Insert the bottom of the belt into the frame, then

pull down on the belt and roll it onto the large, forward-most groove of the transmission pulley (P, Figure 5-20).

7. Reinstall the belt cover.

8. Test for correct tension on the forward

clutch belt (see Checking Forward Belt Tension).

REVERSE CLUTCH BELT REMOVAL AND REPLACEMENT

The reverse clutch belt (J, Figure 5-22) is

driven by the engine drive pulley (I, Figure 5-20). When the Reverse Clutch Control knob is pulled out, it pulls the reverse idler arm and pulley (N) which tightens the belt against the engine drive pulley. This drives the transmission drive pulley (L), resulting in reverse motion.

Removing Reverse Clutch Belt

1. Stop engine, allow it to cool and dis-

connect spark plug wire before working near belts. Also remove ignition key on electric start models.

2. Remove belt cover (Figure 5-13) by removing two flange locknuts.

3. Pull the reverse clutch belt downward and slip it off the transmission pulley (L, Figure 5-22).

4. Use two 1/2" wrenches to loosen and remove wire belt guide (R, Figure 5-22) from the reverse idler arm pulley. Do not remove locknut and screw.

5. Remove the reverse belt and pull it out through front of transmission housing.

Installing Reverse Clutch Belt

1. Stop engine, allow it to cool and dis-

connect spark plug wire before working near belts. Also remove ignition key on electric start models.

IMPORTANT: The forward clutch belt must be installed before the reverse clutch belt.

2. Install the forward clutch belt (see Installing Forward Clutch Belt in this section) before installing reverse belt.

IMPORTANT: The reverse belt has a ‘V” shape. When installing the belt, make sure that the widest (flat) side of the belt rides against the reverse idler pulley (N, Figure 5-22) and transmission pulley (L). If needed, the belt can be twisted “inside out” so that the “V” shaped side is on the outside and the widest side is on the inside.

3. Insert the belt down into the front of the transmission housing. Slip the top half of the belt onto the reverse idler arm pulley (N).

4. Pull the belt downward and loop the bottom half of belt around the front groove of transmission pulley (L, Figure 5-22).

5. Mount the belt guide between the two flat washers and tighten snugly. The guide needs adjusting before fully tightening.

6. (You will need an assistant to help with this step.) Pull the reverse idler pulley (N) up to its highest point and position the belt guide (R) horizontally level as shown in Figure 5-23. Securely tighten the screw and lock nut (M, Figure 5-22).

7. Pull back on the Reverse Clutch Control knob and make sure that the reverse clutch belt fully contacts the groove in the engine pulley. Release knob and make sure that the belt doesn’t engage the reverse engine pulley. This may cause the unit to move in reverse when the Wheel Gear Lever is engaged. Adjust the cable for less tension if this condition occurs. See Checking and Adjusting Reverse Belt Tension for more information.

8. Reinstall the belt cover and secure it with two flange locknuts.

9. Test the unit in an open location.
