Safety

This machine meets or exceeds European Standards in effect at the time of production. However, improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death.

symbol, which means CAUTION,

Safe Operating Practices

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

POTENTIAL HAZARD

• Engine exhaust contains carbon monoxide,

which is an odorless, deadly poison.

WHAT CAN HAPPEN

• Carbon monoxide can kill you and is also

known to the State of California to cause birth defects.

General Operation

1. Read, understand, and follow all instructions in

the operator’s manual and on the machine before starting.

2. Allow only responsible adults who are familiar

with the instructions to operate the machine.

3. Clear the area of objects such as rocks, toys,

wire, etc., which could be picked up and thrown by the blade.

4. Be sure the area is clear of other people before

mowing. Stop the machine if anyone enters the area.

5. Never carry passengers.

6. Do not mow in reverse unless absolutely

necessary. Always look down and behind before and while backing.

7. Be aware of the mower discharge direction and

do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.

8. Slow down before turning. Sharp turns on any

terrain may cause loss of control.

HOW TO AVOID THE HAZARD

• Do not run engine indoors or in an enclosed

area.

9. Never leave a running machine unattended.

Always turn off blades, set parking brake, stop engine, and remove key before dismounting.

10. Turn off blades when not mowing.

11. Keep hands, feet, hair and loose clothing away

from attachment discharge area, underside of mower and any moving parts while engine is running.

12. Stop the engine before removing the grass

catcher or unclogging the chute.

13. Mow only in daylight or good artificial light.

Page 5

Safety

14. Do not operate the machine while under the

influence of alcohol or drugs.

15. Watch for traffic when operating near or crossing

roadways.

16. Use extra care when loading or unloading the

machine onto a trailer or truck.

17. Do not touch equipment or attachment parts

which may be hot from operation. Allow to cool before attempting to maintain, adjust or service.

Slope Operation

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.

• Keep all movement on slopes slow and gradual.

Do not make sudden changes in speed or direction.

• Avoid starting or stopping on a slope. If tires

lose traction, disengage the blades and proceed slowly straight down the slope.

DO NOT

• Do not operate machine on hillsides or slopes exceeding 15°.

• Avoid turning on slopes. If you must turn, turn slowly and gradually downhill, if possible.

• Do not mow near drop-offs, ditches, or embankments. The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.

• Do not mow on wet grass. Reduced traction could cause sliding.

• Mow up and down slopes greater than 5°, not

across.

• Mow downhill only on slopes above 10°, never

mow uphill. If a steep slope must be ascended, back up the hill, and drive forward down the hill, keeping the machine in gear.

• Remove obstacles such as rocks, tree limbs, etc.

from the mowing area. Watch for holes, ruts or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

• Use slow speed. Choose a low gear so that you

will not have to stop or shift while on the slope.

• Follow the manufacturer’s recommendations for

wheel weight or counterweights to improve stability.

• Use extra care with grass catchers or other

attachments. These can change the stability of the machine.

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

• Do not use a grass catcher on steep slopes. Heavy grass bags could cause loss of control or overturn the machine.

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them. The following requirements must be followed to prevent injury to children.

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

2. Be alert and turn the machine off if children enter the area.

3. Before and while backing, look behind and down for small children.

Page 6

Safety

4. Never carry children. They may fall off and be

seriously injured or interfere with safe machine operation.

5. Never allow children to operate the machine.

6. Use extra care when approaching blind corners,

shrubs, trees, the end of a fence or other objects that may obscure vision.

Service

1. Stop the engine and disconnect spark plug

wire(s) before performing any service, repairs, maintenance or adjustments.

2. Use extra care when handling gasoline and other

fuels. They are flammable and vapors are explosive.

A. Use only an approved container. B. Never remove the gas cap or add fuel when

the engine is running. Allow the engine to

cool before refueling. Do not smoke. C. Never refuel the machine indoors. D. Never store the machine or fuel container

inside where there is an open flame, such as

Gasoline and Oil

Recommended Gasoline

Use UNLEADED Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.

IMPORTANT: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

POTENTIAL HAZARD

• In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn

you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• Use a funnel and fill the fuel tank outdoors,

in an open area, when the engine is cold. Wipe up any gasoline that spills.

• Do not fill the fuel tank completely full.

Add gasoline to the fuel tank until the level is 1/4” to 1/2” (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and

stay away from an open flame or where gasoline fumes may be ignited by a spark.

• Store gasoline in an approved container

and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

POTENTIAL HAZARD

• In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

• A fire or explosion from gasoline can burn

you, others, and cause property damage.

HOW TO AVOID THE HAZARD

• Always place gasoline containers on the

ground away from your vehicle before filling.

• Do not fill gasoline containers inside a

vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

• When practical, remove gas–powered

equipment from the truck or trailer and refuel the equipment with its wheels on the round.

• If this is not possible, then refuel such

equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used,

keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Page 13

Gasoline and Oil

Stabilizer/Conditioner

Add the correct amount of gas stabilizer/conditioner to the gas. Using a stabilizer/conditioner in the machine:

• Keeps gasoline fresh during storage of 90 days

or less. For longer storage it is recommended that the fuel tank be drained.

• Cleans the engine while it runs

• Eliminates gum-like buildup in the fuel system,

which causes hard starting

IMPORTANT: Never use fuel additives containing methanol or ethanol.

Filling the Fuel Tank

1. Shut the engine off and set the parking brake.

2. Clean around each fuel tank cap and remove the

cap. Add unleaded regular gasoline to both fuel tanks, until the level is 1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tanks completely full.

3. Install fuel tank caps securely. Wipe up any

gasoline that may have spilled.

4. Fuel gauge is located in right side tank.

Check Engine Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking Oil Level, page 30.

Operation

The Safety Interlock System

Understanding the Safety Interlock System

The safety interlock system is designed to prevent the engine from starting unless:

• The power take off (PTO) is “OFF”

• The gear shift lever is in “N” neutral.

The safety system is designed to stop the engine if:

• You rise from the seat when the clutch/brake

pedal is released.

• You rise from the seat when the blade (PTO) is

“ENGAGED.”

• You shift into reverse with the power take off

(PTO) engaged and the operating–in–reverse interlock not deactivated.

Before deactivating this feature, be sure there are no children present on or near the property where you are using the tractor, and that none are likely to appear while you are mowing or operating an attachment. Be extra observant after you have chosen to deactivate the interlock feature because the sound of the tractor’s engine might prevent you from being aware that a child or a bystander has entered the area where you are operating the tractor.

If you are certain that you can safely mow in reverse or operate an attachment, deactivate the operating–in–reverse interlock feature by turning the “Key Choice” switch (Fig. 10), located in front of and below the seat, after engaging the blade (PTO). A red light on the front console (Fig. 11) will turn on as a reminder that the operating–in–reverse interlock has been deactivated. Once the interlock is deactivated it stays in this mode––with your mower blade or PTO–driven attachment operating whenever you back up–– and the console light stays on until either the blade (PTO) is disengaged, or the engine is turned off.

Operating–in–Reverse

An interlock feature is provided that prevents the Power Take Off (PTO) from operating while the tractor is traveling in reverse. If the unit is shifted into reverse while the mower blade or other PTO driven attachment is engaged, the engine will stop.

Do not mow while backing up unless it is absolutely necessary. If you need to mow while in

reverse gear or use other PTO driven attachments (such as a snowthrower or tiller), this operating–in–reverse interlock feature may be temporarily deactivated.

Note: Do not insert the “Key Choice” key

unless it is absolutely necessary to mow in reverse or operate an attachment. The “Key Choice” key should also be removed from the unit if it will be operated by someone other than a responsible, experienced operator. This will prevent the unit from operating in reverse with the mower blade or other PTO attachment engaged. Always remove both the ignition and the “Key Choice” keys and put them in a safe place out of the reach of children when leaving the unit unattended.

Page 23

POTENTIAL HAZARD

• A child or bystander could be backed over

by a riding mower with its blade(s) engaged.

WHAT CAN HAPPEN

• Blade contact will cause serious personal

injury or death.

HOW TO AVOID THE HAZARD

• Do not mow in reverse unless absolutely

necessary.

• Always look backward and down before

backing up.

• Use “Key Choice” switch only if you are

certain no children or other bystanders will appear in the mowing area.

• Always remove both the ignition and Key

Choice keys and put them in a safe place out of the reach of children or unauthorized users when leaving the unit unattended.

4. Sit on the seat, move gear shift into neutral, deck

engagement lever into DISENGAGE and ensure parking brake is engaged. Rotate ignition key to START. Engine should start and continue to run. Then engage deck engagement lever and carefully raise off the seat: the engine should stop. If the engine does not stop running, shut the engine off and have interlock system repaired by an Authorized TORO Service Dealer. If the engine shuts off when you raise off the seat, the interlock system is functioning correctly and the rider can be operated safely.

5. Put the PTO lever in the “disengage” position

and the gear shifter in neutral. Now start the engine. While the engine is running, move the PTO lever to the “engage” position, push in the clutch and put the gear shifter in reverse. The engine should stop.

6. Put the PTO lever in the “disengage” position

and the gear shifter in neutral. Now start the engine. Move the PTO lever to the “engage” position and turn the “Key Choice” key and release. The Key Choice warning light should illuminate. Move the PTO lever to the “disengage” position and the Key Choice warning light should turn off.

For improved bagger performance change to high sail blade and remove Recycler kickers. If you no longer wish to side discharge or bag clippings, the discharge cover can be reinstalled by securing it the mower housing with the wing nut.

Page 25

Operation

IMPORTANT: When the discharge cover is in place, it must be secured to the grass deflector with the metal tab and wingnut.

POTENTIAL HAZARD

• Without the grass deflector, discharge

cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.

WHAT CAN HAPPEN

• Contact with rotating mower blades(s) and

thrown debris will cause injury or death.

HOW TO AVOID THE HAZARD

• NEVER remove the grass deflector from

the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.

• Never put your hands or feet under the

mower.

• Never try to clear discharge area or mower

blades unless you move the power take off (PTO) to “OFF” and rotate the ignition key to “OFF”. Also remove the key and pull the wire off the spark plug(s).

Note: For reverse motion, with the PTO

engaged, the operating–in–reverse interlock must be deactivated by the key choice switch located in front of and below the seat.

Stopping the Machine

To stop the machine, push the clutch in and shift to neutral (”N”). Disengage the power take off (PTO), and turn the ignition key to “OFF” to stop the engine. Also set the parking brake if you leave the machine unattended; refer to Setting the Parking Brake, page 17. Remember to remove the keys from the ignition and “Key Choice” switches.

POTENTIAL HAZARD

• Someone could move or attempt to operate

the tractor while it is unattended.

WHAT CAN HAPPEN

• Children or bystanders may be injured if

they use the tractor.

HOW TO AVOID THE HAZARD

• Always remove the ignition and “Key

Choice” keys and set the parking brake when leaving the machine unattended, even if just for a few minutes.

Driving Forward or Backward

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the “FAST” position for best performance while mowing.

To go forward push the clutch in and place the gear shifter in a forward gear, release the parking brake: refer to Releasing the Parking Brake, page 18 and slowly release the clutch. To go in reverse push the clutch in to stop and after stopping completely, place the gear shifter in reverse. Slowly release the clutch.

IMPORTANT: Do not “Ride the Brakes”. Shift to a lower speed for slower ground speed. Choose a slow speed so that you will not have to stop or shift while on the slope.

Page 26

Operation

Positioning the Seat

The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable.

1. Raise the seat and loosen the lock nuts (Fig. 13).

2. Slide the seat to the desired position and tighten

the lock nuts.

RecyclerMowing Tips

Recycler Rider Features

Your Toro Recycler rider has a new and completely different cutting concept. It leaves your lawn with a bagged look without bagging clippings.The rider is equipped with special parts (Fig. 14) which increase your rider’s ability to cut and recut grass clippings, leaves, and other yard debris into tiny particles which are injected down into the grass. These parts are:

• Deck ring

• Special blade and blade stiffener

• Discharge cover

• Four special “kickers” strategically positioned on

the underside of the mower deck. A fifth kicker is molded into the discharge cover.

Tips for Cutting Grass

Operation

Even with the Recycler rider, you may encounter conditions where it is not possible to incorporate all of the grass clippings or leaves all of the time into the grass. Follow these instructions for the best cutting results and lawn appearance:

• Always use FAST (full) throttle when mowing.

• Maintain a sharp blade

season. A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases. About every 30 days, remove the wire from the spark plug and check the cutter blade for sharpness. File down any nicks on blade to restore its sharp edge.

• Clean any residue from the underside of the rider

housing and kickers after each use. If residue is allowed to build up in rider housing and on kickers, cutting performance may be unsatisfactory.

• Very long or extremely wet grass can be cut, but

specific operating techniques must be used. Start by setting height-of-cut in the highest position. Using 1st gear and maximum throttle speed, move into the grass and cut a swath that is only half as wide as the mower housing. If side discharging, direct grass clippings toward area that was cut previously. Stop forward movement occasionally to allow discharge area to clear itself. Cutting too much grass may clog the mower housing and discharge area. If mower housing does clog, shut engine off, disengage blade and remove the obstruction with a stick.

throughout the cutting

POTENTIAL HAZARD

• Unexpected blade contact can occur

WHAT CAN HAPPEN

• Personal injury can occur from contact

with blade

HOW TO AVOID THE HAZARD

• Depress clutch and brake pedals, shift into

neutral and turn ignition key to “OFF” position. Remove wire from spark plug to prevent someone from accidentally starting the machine.

• When the rider is used to cut a lawn for the first

time, cut grass slightly longer than normal to ensure that cutting height of mower housing will not cause scalping, which could result from severe undulations of the ground. In general, however, the cutting height used in the past is probably the best one to use. When cutting grass over six inches tall, you may want to cut the lawn twice to hide clippings down in the grass.

• If the grass is ever allowed to grow slightly

longer than normal, or if it contains a high degree of moisture, raise cutting height higher than usual and cut the grass at this setting. Next, cut the grass again using the lower, normal setting. This method of cutting long grass results in an even distribution of clippings and an acceptable quality-of-cut.

• In the heat of the summer, it is best to cut only

about 1/3 of the grass blade. Cutting below the 3rd setting is not recommended unless grass is sparse or it is late fall when grass growth begins to slow down.

• If the cutting width of the rider is wider than the

mower previously used, raise height-of-cut setting one notch to ensure undulations in turf are not cut too short.

Page 28

Operation

• MOWING IN EXTREME CONDITIONS—Air

is required to cut and recut grass clippings in rider housing, so do not set height-of-cut too low or totally surround housing by uncut grass. Always try to have one side of the rider housing free from uncut grass, allowing air to be drawn into housing. When making an initial cut thru center of uncut area, operate rider at a slower ground speed and back up if rider starts to clog.

• STOPPING RIDER—If forward motion of rider

has to be stopped while cutting, a clump of grass clippings may be deposited on lawn. Follow this procedure for stopping while cutting:

A. With blade engaged, move onto a

previously cut area.

B. Raise deck one or two height-of-cut settings

while driving rider forward and deck is in operation.

C. Depress clutch and brake pedals, move

throttle control lever to IDLE position, disengage mower and rotate ignition key to OFF.

• MOW AT PROPER INTERVALS—Under most

normal conditions you’ll need to mow approximately every 4–5 days. But remember, grass grows at different rates at different times. This means that in order to maintain the same height-of-cut, which is a good practice, you’ll need to cut more frequently in early spring; as the grass growth rate slows in mid summer, cut only every 8–10 days. If you are unable to mow for an extended period due to weather conditions or other reasons, mow first with the height-of-cut at a high level; then mow again 2–3 days later with a lower height setting.

cover to the mower housing. NEVER

REMOVE THE GRASS DEFLECTOR FROM THE MOWER HOUSING.

POTENTIAL HAZARD

• Without the grass deflector, discharge

cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.

WHAT CAN HAPPEN

• Contact with rotating mower blades(s) and

thrown debris will cause injury or death.

HOW TO AVOID THE HAZARD

• NEVER remove the grass deflector from

the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.

• Never put your hands or feet under the

mower.

• Never try to clear discharge area or mower

blades unless you move the power take off (PTO) to “OFF” and rotate the ignition key to “OFF”. Also remove the key and pull the wire off the spark plug(s).

The Recycler rider’s special features reduce clipping size, thus decreasing amount of grass to be disposed of and number of times bagger will have to be emptied.

Note: When bagger is full, mower will begin

to inject clippings down into the grass.

• Alternate mowing direction. This helps disperse

clippings over lawn for even fertilization.

• SIDE DISCHARGING OR BAGGING—To

side discharge or use bagging attachment, stop the engine and wait for all moving parts to stop. Then remove the wing nut securing the discharge

Page 29

If the lawn appearance is not satisfactory after mowing, try one of the following:

• Sharpen the blade.

• Raise the height-of-cut setting on your mower.

• Cut your grass more frequently.

• Reduce ground speed.

• Overlap cutting swaths instead of cutting a full

swath with each pass.

• Mow across the marginal areas a second time.

Tips For Cutting Leaves

In the fall, you can cut your leaves up into finely cut particles and inject the particles down into the grass. When spring arrives, the leaf particles will have decomposed and restored valuable nutrients to the soil.

Operation

• When cutting is complete, always be sure that

50% of the lawn shows through the finely cut leaf cover. This may require one or more passes over the leaves.

• If there are more than five inches of leaves on

lawn, raise the deck one or two notches higher. This makes it easier to feed leaves under mower deck.

• If leaves are not cut up finely enough to be

hidden down in the grass, make a second pass 90 degrees to the first pass.

• If you cut up a lot of oak leaves, you might want

to add lime to your grass in the spring. Lime reduces the acidity of oak leaves.

POTENTIAL HAZARD

• Worn, eroded or cracked blade can be

dangerous.

WHAT CAN HAPPEN

• Blade can fail and cause personal injury to

bystanders.

HOW TO AVOID THE HAZARD

• Check blade often

• Replace if bent or out of balance

• Use genuine Toro replacement blade to

ensure safety and best performance. NEVER USE A WILL–FIT REPLACEMENT BLADE.

IMPORTANT: Sharpen top side of the blade and maintain original cutting angle to ensure a sharp cutting edge. The blade will remain balanced if same amount of material is removed from both cutting edges.

6. Check balance of blade by putting it on a blade

balancer. (An inexpensive balancer can be purchased at a hardware store.) A balanced blade will stay in a horizontal position on the balancer. By contrast, a blade that is not balanced will settle to the heavy side. If blade is not balanced, file more material off cutting edge of the blade. Continue to file and check the blade until it is balanced.
