Preparation

• While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.

• Thoroughly inspect the area where the equipment is to be used and remove all stones, sticks, wires, bones and other foreign objects.

• Before using, always visually inspect to see that guards, and safety devices, such as deflectors and/or grass catchers, are in place and working correctly.

• Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

Starting

• Disengage all blade and drive clutches and shift into neutral before starting the engine.

• Do not tilt mower when starting the engine or switching on the motor, unless the mower has to be tilted for starting. In this case, do not tilt it more than absolutely necessary and lift only the part, which is away from the operator.

• Start the engine or switch on the motor carefully according to instructions and with feet well away from the blade(s) and not in front of the discharge chute.

Operation

• Never mow while people, especially children, or pets are nearby.

• Mow only in daylight or in good artificial light.

• Stay alert for holes in the terrain and other hidden

hazards.

• Never direct discharge of material towards bystanders.

• Avoid operating the equipment in wet grass, where

feasible.

• Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.

• Never pick up or carry a lawn mower while the engine is running.

• Use extreme caution when reversing or pulling a pedestrian controlled lawn mower towards you.

• Walk, never run.

• Slopes:

– Do not mow excessively steep slopes.

– Exercise extreme caution when on slopes.

– after striking a foreign object, inspect the lawn

mower for damage and make repairs before restarting and operating the lawn mower.

– if lawn mower starts to vibrate abnormally (check

immediately).

• Reduce the throttle setting during engine shut down, and close the fuel valve at the conclusion of mowing.

Before Starting

Filling the Crankcase with Oil

Initially, fill the crankcase with 30 ounces (0.88 liters) of oil. Use only high-quality SAE 30 or SAE 10W30 weight detergent oil that has the American Petroleum Institute (API) service classification SF, SG, SH, or SJ.

Oil Capacity

With Oil Filter 30 ounces (0.88 L)

Without Oil Filter 24 ounces (0.70 L)

Before each use, ensure that the oil level is between the Add and Full marks on the dipstick (Fig. 7).

5. Insert the dipstick into the filler neck.

Note: To ensure an accurate oil level reading, do not fully

install the dipstick.

6. Remove the dipstick.

7. Read the oil level on the dipstick (Fig. 7).

8. If the oil level reading is below the Add mark on the

dipstick, slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick.

Important Do not overfill the crankcase with oil and

run the engine; engine damage will result. Drain the excess oil until the oil level on the dipstick reads Full.

9. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight.

Filling the Fuel Tank with Gasoline

For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life. You may use leaded gasoline if unleaded gasoline is not available.

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

• Fill the fuel tank outdoors, in an open area, and 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 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows the gasoline to expand.

• Never smoke when handling gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.

• Store gasoline in an approved fuel container and keep it out of the reach of children.

• Never buy more than a 30-day supply of gasoline.

Danger

When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property.

1. Clean around the fuel tank cap (Fig. 8).

2. Fuel tank cap

3. Air cleaner

2. Remove the cap from the tank.

3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 inch (6 to 13 mm) from the top of the tank. Do not fill into the filler neck.

Important Do not fill the tank more than 1/4 inch

(6 mm) from the top of the tank because the gasoline must have room to expand.

4. Install the fuel tank cap and wipe up any spilled gasoline.

• Always place gasoline containers on the ground and 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 gasoline-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, not from a gasoline dispenser nozzle.

• If you must use a gasoline dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Use a fuel stabilizer/conditioner regularly during operation and storage. A stabilizer/conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage.

Important Do not use fuel additives other than a fuel

stabilizer/conditioner . Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Each time before you mow, make sure that the self-propel drive and the blade control bail operate properly. When you release the blade control bail, the blade and self-propel drive should stop. If they do not, contact an Authorized Service Dealer.

Starting the Engine

1. Connect the wire to the spark plug (Fig. 11).

Caution

This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

Note: When grass is thick and lush, clippings may collect

on and around the discharge tunnel plug. This may make removing the plug difficult. Clean the plug thoroughly after each use.

m-3769

Figure 13

2. Slide the blade control bail to the right and raise it to the B position to engage the blade (Fig. 13).

3. Squeeze the blade control bail against the handle to the C position to drive (Fig. 13).

Note: To disengage the traction drive but keep the blade

engaged, gradually release the blade control bail to the B position. To self-propel with the blade disengaged, squeeze the blade control bail against handle to the C position without sliding the blade control bail to the right.

The lawn mower has 3 ground speeds. 1 is slow, 2 is medium, and 3 is fast. The ground speed control is located at the rear of the belt cover (Fig. 12).

Checking the Blade Brake Clutch

Check the blade control bail before each use to ensure that the blade brake clutch (BBC) system is operating properly.

Normal Test

1. Stop the engine and wait for all moving parts to stop.

2. Move the lawn mower onto a paved surface in a

non-windy area.

3. Set all 4 wheels in to the 2-1/2 in. (64 mm) cutting height setting (Fig. 19).

4. Set the ground speed selector to the N (Neutral) position.

5. Take a half sheet of newspaper and crumple it into a ball small enough to go under the deck (about 3 in. or 76 mm in diameter) as shown in Figure 14.

Note: You can vary the ground speed by increasing or decreasing the distance between the control bar and the handle. Lower the control bar to slow the lawn mower when making a turn or if the lawn mower is moving too fast for you. If you lower the control bar too far, the lawn mower stops self-propelling. Squeeze the control bar closer to the handle to increase the ground speed. When you hold the control bar tight against the handle, the lawn mower self-propels at the maximum ground speed. Move

the ground speed control to the (Neutral) position when you use the lawn mower for trimming and whenever you leave the lawn mower.

Using the Discharge Tunnel Plug

Figure 17

11. Immediately push the lawn mower over the newspaper ball.

12. Stop the engine and wait for all moving parts to stop.

13. Walk around the lawn mower to check for the

newspaper ball. If the ball did not go under the deck, repeat steps 6 through 12.

m-5086

Figure 18

Note: This intermediate position (C) is not the normal operating position of the blade control bail. However, it helps to detect a sticking BBC system early enough to prevent an unsafe condition later.

4. Release the blade control bail (Position B in Fig. 18).

Note: If you hear a loud “bang,” you have raised the blade

control bail too high. Repeat steps 2 through 4 above, but do not raise the blade control bail as high as in step 3.

5. Immediately push the lawn mower over the newspaper ball.

6. Stop the engine and wait for all moving parts to stop.

7. Walk around the lawn mower to check for the

newspaper ball. If the ball did not go under the deck:

A. Place the ball of newspaper 5 inches (12.7 cm) in

front of the lawn mower (Fig. 14).

B. Start the engine.

C. Follow steps 2 through 6 above.

8. Pull the lawn mower away from the newspaper. If the newspaper ball unravels or is shredded, the BBC system could be deteriorating to the point where it

could result in an unsafe operating condition. Contact an Authorized Service Dealer for an inspection and repair of your lawn mower.

Danger

If the blade brake clutch system is inoperative, the blade will continue to rotate when you release the blade control bail. Contact with blade could occur, causing serious injury.

Danger

Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury.

• Stop the engine and wait for all movement to stop before adjusting the cutting height.

• Do not put your fingers under the housing when adjusting the cutting height.

• Check the BBC operation before each use.

• Never use a BBC-equipped lawn mower with an

inoperative safety system.

• Take your lawn mower to an Authorized Service Dealer for repair if the safety system fails to operate properly.

Test Using the Grass Bag

You can use the grass bag to perform an additional test to check the blade brake clutch mechanism:

1. Install the empty grass bag on the discharge tunnel.

2. Start the engine.

3. Push the blade control bail (Fig. 15) down to its lowest

position.

4. Lift the blade control bail to the normal blade engaged position about one inch (2.5 cm) below the handle. The bag should begin to inflate, indicating that the blade is engaged and rotating.

5. Release the blade control bail. If the bag does not immediately deflate, it indicates that the blade is still rotating. The blade brake clutch mechanism may be deteriorating, and, if ignored, could result in an unsafe operating condition. Have the lawn mower inspected and serviced by an Authorized Service Dealer.

page 14.

m-1913

Figure 21

1. Pin locked in bag notch

Note: The discharge door in the lawn mower housing is now open.

Danger

If the discharge door does not close completely, the lawn mower could throw objects, causing serious personal injury or death.

If you cannot close the door because the grass clippings clog the discharge area, stop the engine and gently move the discharge door handle back and forth until you can close the door completely. If you still cannot close the door, remove the obstruction with a stick, not your hand.

Danger

The lawn mower can throw grass clippings and other objects through an open discharge tunnel. Objects thrown with enough force could cause serious personal injury or death to the operator or bystander.

Never open the door on the discharge tunnel when the engine is running.

Operating Tips

• Review the safety instructions and read this manual carefully before operating the lawn mower.

• Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.

• Keep everyone, especially children and pets, away from the area of operation.

• Avoid striking trees, walls, curbs, or other solid objects. Never deliberately mow over any object.

• If the lawn mower strikes an object or starts to vibrate, immediately stop the engine, disconnect the wire from the spark plug, and examine the lawn mower for damage.

• Maintain a sharp blade throughout the cutting season. Periodically file down nicks on the blade.

• Replace the blade when necessary with an original Toro replacement blade.

• Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the lawn mower to plug or the engine to stall.

Cutting Grass

• Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 2 inch (51 mm), 2-1/2 inch (64 mm), or 3 inch (76 mm) cutting height settings. Cut only about a third of the grass blade at a time. Do not cut below the 2 inch (51 mm) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.

• When cutting grass over 6 inches (15 cm) tall, first mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the lawn mower may plug and cause the engine to stall.

• Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization.

If the finished lawn appearance is unsatisfactory, try one or more of the following:

• Sharpen the blade.

• Walk at a slower pace while mowing.

• Raise the cutting height on your lawn mower.

Warning

Wet grass or leaves can cause serious injury if you slip and contact the blade.

Mow only in dry conditions.

• Clean the underside of the lawn mower deck after each mowing. See Cleaning the Underside of the Lawn Mower Housing on page 18.

• Keep the engine in good running condition.

• Set the engine speed to the fastest position for the best

cutting results.

Warning

Operating a lawn mower with its engine running at a speed greater than the factory setting can cause the lawn mower to throw a part of the blade or engine into the operator’s or bystander’s area and result in serious personal injury or death.

• Do not change the engine speed setting.

• If you suspect the engine speed is faster than

normal, contact an Authorized Service Dealer.

• Cut the grass more frequently.

• Overlap cutting swaths instead of cutting a full swath

with each pass.

• Set the cutting height on the front wheels one notch lower than the rear wheels. For example, set the front wheels at 2 inches (51 mm) and the rear wheels at 2-1/2 inches (64 mm).

Cutting Leaves

• After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than one pass over the leaves.

• For light leaf coverage, set all the wheels at the same cutting height setting.

• If there are more than 5 inches (12.7 cm) of leaves on the lawn, set the front cutting height 1 or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the lawn mower deck.

• Slow down your mowing speed if the lawn mower does not cut the leaves finely enough.

• If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak leaves.

• Clean the air filter frequently. Mulching stirs up more clippings and dust which clogs the air filter and reduces engine performance.

Maintenance

Note: Determine the left and right sides of the machine from the normal operating position.
