The warning system in this manual identifies

potential hazards and has special safety messages that

help you and others avoid personal injury, even death.

DANGER, WARNING and CAUTION are signal

words used to identify the level of hazard. However,

regardless of the hazard, be extremely careful.

DANGER signals an extreme hazard that will cause

serious injury or death if the recommended

precautions are not followed.

WARNING signals a hazard that may cause serious

injury or death if the recommended precautions are

not followed.

CAUTION signals a hazard that may cause minor or

moderate injury if the recommended precautions are

not followed.

Two other words are also used to highlight

information. “Important” calls attention to special

mechanical information and “Note” emphasizes

general information worthy of special attention.

The left and right side of the machine is determined

by sitting on the seat in the normal operator’s

position.

Operation

Side Discharge

The mower has a hinged grass deflector that disperses

clippings to the side and down toward the turf.

POTENTIAL HAZARD

•Without the grass deflector 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 blade(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(s) off the spark plug(s).

The power take off (PTO) engages and disengages

power to the attachment clutch.

Operating the Power Take Off

(PTO)

The power take off (PTO) switch engages and

disengages power to the electric clutch.

Engaging the PTO

1. Release pressure on the traction control levers

and place in neutral, refer to traction unit

Operator’s Manual.

2. Release the parking brake, refer to traction unit

Operator’s Manual.

3. Pull out on the power take off (PTO) switch to

engage (Fig. 3).

Disengaging the PTO

position (Fig. 3).

Operation

Adjusting Height-of-Cut

The height-of-cut is adjusted from 1-1/2” to 5”

(38 to 127 mm) in 1/2” (13 mm) increments by

relocating clevis pin in different hole locations.

1. Raise the height-of-cut lever to the transport position

(also the 5” (127 mm) cutting height position) (Fig. 4).

2. To adjust, remove hairpin cotter and clevis pin

from height-of-cut bracket (Fig. 4).

3. Select hole in height-of-cut bracket

corresponding to the height-of-cut desired. Lift

handle to transport position, insert clevis pin

(Fig. 4).

4. Secure clevis pin with hairpin cotter (Fig. 4).

Adjusting Anti-Scalp Rollers

Whenever you change the height-of-cut you must also

adjust the height of the anti-scalp rollers.

Stop the engine before adjusting the anti-scalp rollers.

1. Raise the height-of-cut lever to the transport position

(also the 5” (127 mm) cutting height position) (Fig. 4).

2. Adjust anti–scalp rollers for maximum deck

flotation. Place rollers in one of the positions

shown in (Fig. 5).

Note: Do not adjust rollers to support the

deck.

3. Reposition the roller so it’s approximately 1/4”

to 3/8” (6 to 10 mm) above the ground, then

insert the clevis pin through the gauge wheel

plate and mounting bracket (Fig. 5).

4. Be sure bolt is tightened properly or loss of

anti-scalp roller may result.

Operation

Tips for Mowing Grass

Fast Throttle Setting

For best mowing and maximum air circulation,

operate the engine at “FAST.” Air is required to

thoroughly cut grass clippings, so do not set the

height-of-cut so low as to totally surround the mower

by uncut grass. Always try to have one side of the

mower free from uncut grass, which allows air to be

drawn into the mower.

Cutting a Lawn for the First Time

Cut grass slightly longer than normal to ensure the

cutting height of the mower does not scalp any

uneven ground. However, the cutting height used in

the past is generally the best one to use. When cutting

grass longer than six inches tall, you may want to cut

the lawn twice to ensure an acceptable quality of cut.

Cut 1/3 of the Grass Blade

It is best to cut only about 1/3 of the grass blade.

Cutting more than that is not recommended unless

grass is sparse, or it is late fall when grass grows

more slowly.

Mowing Direction

Alternate mowing direction to keep the grass standing

straight. This also helps disperse clippings which

enhances decomposition and fertilization.

Mow at Correct Intervals

Normally, mow every four days. But remember, grass

grows at different rates at different times. So to

maintain the same cutting height, which is a good

practice, mow more often in early spring. As the

grass growth rate slows in mid summer, mow less

frequently. If you cannot mow for an extended period,

first mow at a high cutting height; then mow again

two days later at a lower height setting.

Cutting Speed

To improve cut quality, use a slower ground speed.

Avoid Cutting Too Low

If the cutting width of the mower is wider than the

mower you previously used, raise the cutting height

to ensure that uneven turf is not cut too short.

Long Grass

If the grass is ever allowed to grow slightly longer

than normal, or if it contains a high degree of

moisture, raise the cutting height higher than usual

and cut the grass at this setting. Then cut the grass

again using the lower, normal setting.

When Stopping

If the machine’s forward motion must be stopped

while mowing, a clump of grass clippings may drop

onto your lawn. To avoid this, move onto a

previously cut area with the blades “ENGAGED”.

Keep the Underside of the Mower Clean

Clean clippings and dirt from the underside of the

mower after each use. If grass and dirt build up inside

the mower, cutting quality will eventually become

unsatisfactory.

Blade Maintenance

Maintain a sharp blade throughout the cutting season

because a sharp blade cuts cleanly without tearing or

shredding the grass blades. Tearing and shredding

turns grass brown at the edges, which slows growth

and increases the chance of disease. Check the cutter

blades daily for sharpness, and for any wear or

damage. File down any nicks and sharpen the blades

as necessary. If a blade is damaged or worn, replace it

immediately with a genuine TORO replacement

blade.

Cutting Blades

To ensure a superior quality of cut, keep the blades

sharp. For convenient sharpening and replacement,

you may want to keep extra blades on hand.

POTENTIAL HAZARD

•A blade that is worn or damaged could

break apart and pieces could be thrown at

bystanders or at you as you use the mower.

WHAT CAN HAPPEN

•Pieces of blade that may be thrown could

seriously injure or kill you or bystanders.

HOW TO AVOID THE HAZARD

•Periodically inspect the blade for wear and

damage. Immediately install a new blade if

it is worn or damaged.

Before Inspecting or Servicing the

Blades

Park the machine on a level surface, disengage the

blade control (PTO) and set the parking brake. Turn

the ignition key to “OFF” to stop the engine. Remove

the key and disconnect the spark plug wire(s) from

the spark plug(s).
