Table of Contents

Specifications

• Refuel outdoors only and do not smoke while

refueling.

• Add fuel before starting the engine. Never

remove the cap of the fuel tank or add petrol

while the engine is running or when the engine

is hot.

• If petrol 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 petrol vapors have dissipated.

• Replace all fuel tanks and container caps

securely.

4. Replace faulty silencers.

5. 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.

6. On multi-bladed machines, take care as rotating

one blade can cause other blades to rotate.

Operation

1. Do not operate the engine in a confined space

where dangerous carbon monoxide fumes can col-

lect.

2. Mow only in daylight or in good artificial light.

3. Before attempting to start the engine, disengage all

blade attachment clutches and shift into neutral.

4. Do not use on slopes of more than:

• Never mow side hills over 5°

• Never mow uphill over 10°

• Never mow downhill over 15°

5. Remember there is no such thing as a “safe” slope.

Travel on grass9 slopes requires particular care. To

guard against overturning:

• do not stop or start suddenly when going up or

downhill;

• engage clutch slowly, always keep machine in

gear, especially when travailing downhill;

• machine speeds should be kept low on slopes

Training

1. Read the instructions carefully. Be familiar with

the controls and the proper use of the equipment.

2. Never allow children or people unfamiliar with

these instructions to use the lawnmower. Local reg-

ulations may restrict the age of the operator.

3. Never mow while people, especially children, or

pets are nearby.

4. Keep in mind that the operator or user is responsi-

ble for accidents or hazards occurring to other peo-

ple or their property.

5. Do not carry passengers.

6. All drivers should seek and obtain professional and

practical instruction. Such instruction should

emphasize:

• the need for care and concentration when work-

ing with rideon machines;

• control of a ride on machine sliding on a slope

will not be regained by the application of the

brake. The main reasons for loss of control are:

– insufficient wheel grip;

– being driven too fast;

– inadequate braking;

– the type of machine is unsuitable for its task;

– lack of awareness of the effects of ground

conditions, especially slopes;

Preparation

1. While mowing, always wear substantial footwear

and long trousers. Do not operate the equipment

when barefoot or wearing open sandals.

2. Thoroughly inspect the area where the equipment is

to be used and remove all objects which may be

thrown by the machine.

3. WARNING—Petrol is highly flammable.

• Store fuel in containers specifically designed for

this purpose.

SAFETY

• if the machine starts to vibrate abnormally

(check immediately).

14. Disengage drive to attachments when transporting

or not in use.

15. Stop the engine and disengage drive to attachment

• before refueling;

• before removing the grass catcher;

• before making height adjustment unless adjust-

ment can be made from the operator's position.

16. Reduce the throttle setting during engine runout

and, if the engine is provided with a shutoff valve,

turn the fuel off at the conclusion of mowing.

Maintenance and Storage

1. Keep all nuts, bolts and screws tight to be sure the

equipment is in safe working condition.

2. Never store the equipment with petrol in the tank

inside a building where fumes may reach an open

flame or spark.

3. Allow the engine to cool before storing in any

enclosure.

4. To reduce the fire hazard, keep the engine, silencer,

battery compartment and petrol storage area free of

grass, leaves, or excessive grease.

5. Check the grass catcher frequently for wear or

deterioration.

6. Replace worn or damaged parts for safety.

7. If the fuel tank has to be drained, this should be

done outdoors

8. On multi-bladed machines, take care as rotating

one blade can cause other blades to rotate.

9. When machine is to be parked, stored or left unat-

tended, lower the cutting means unless a

and during tight turns;

• stay alert for bumps and hollows and other hidden

hazards;

• never mow across the face of the slope, unless the

lawnmower is designed for this purpose.

6. Use care when pulling loads or using heavy equip-

ment.

• Use only approved drawbar hitch points.

• Limit loads to those you can safely control.

• Do not turn sharply. Use care when reversing.

• Use counterweight(s) or wheel weights when sug-

gested in the instruction handbook .

7. Watch out for traffic when crossing or near road-

ways.

8. Stop the blades rotating before crossing surfaces

other than grass.

9. When using any attachments, never direct discharge

of material toward bystanders nor allow anyone near

the machine while in operation .

10. Never operate the lawnmower with defective guards,

shields or without safety protective devices in place.

11. Do not change the engine governor settings or over-

speed the engine. Operating the engine at excessive

speeds may increase the hazard of personal injury.

12. Before leaving the operator's position:

• disengage the power take-off and lower the

attachments;

• change into neutral and set the parking brake;

• stop the engine and remove the key.

13. Disengage drive to attachments, stop the engine, and

disconnect the spark plug wire(s)or remove the igni-

tion key

• before cleaning blockages or unclogging chute;

• before checking, cleaning or working on the

lawnmower;

• after striking a foreign object. Inspect the lawn-

mower for damage and make repairs before

restarting and operating the equipment;

CHECK LUBRICANT IN GEAR BOX

(Fig. 1)

The gear box is designed to operate with SAE 80-90 wt.

gear lube. Although the gear box is shipped with lubricant

from the factory, check the level before operating the cutting

unit.

1. Position the machine and cutting unit on a level sur-

face.

2. Remove the check plug from the side of the gear box

and make sure the lubricant is up to the bottom of the

hole. If the lubricant level is low, remove the fill plug

on top of the gear case and add enough lubricant to

bring it up to the bottom of the hole in the side.

ADJUSTING HEIGHT OF CUT (Fig. 2–5)

The height of cut is adjustable from 2.5 to 12.7 cm in 2.5

cm increments.

1 Start the engine and raise the cutting unit. Stop the

engine after the cutting unit is raised.

2. Remove front snapper pins from castor arms and slide

castor wheel assembly up or down.

3. Insert the snapper pin into the castor arm and through

the groove in the castor shaft to get the desired height

of cut

4. Remove hair pin cotter and clevis pin securing height-of-

cut straps to rear of deck.

5. Mount the height-of-cut straps to desired height-of-cut

hole with the clevis pin and hair pin cotter.

6. When using 2.5 cm height of cut, move skids, rollers,

and wing wheels to the highest holes.

ADJUSTING SKIDS (Fig. 4)

Skids should be located in upper holes for 2.5 and 3.8 cm

heights of cut and lower holes for 5 to 12.7 cm heights of

cut.

1. Adjust skids by removing flange nuts, positioning as

desired and installing the flange nuts.

ADJUSTING ROLLERS (Fig. 6)

Rollers should be located in the upper holes for 2.5 and 3.8

cm heights of cut and lower holes for 5 to 12.7 cm heights

of cut. Five rollers are located on the deck, three under the

main deck and one on each wing.

1. Adjust the rollers by removing the lock nut and bolt,

positioning as desired and then installing the lock nut

and bolt.

ADJUSTING DECK PITCH(Fig. 7)

Deck pitch is the difference in height of cut from the front of

the blade plane to the back of the blade plane. TORO rec-

ommends a blade pitch of 6.4 mm ,i.e., the back of the blade

plane is .6.4 mm higher than the front.

1. Position the machine on a level surface on the shop

floor.

2. Set the deck to the desired height of cut.

3. Rotate (1) blade so it points straight forward.

4. Using a short ruler, measure from the floor to the front

tip of the blade and remember this dimension. Then,

measure from the floor to the rear tip of the blade.

5. Subtract the front dimension from rear dimension to

calculate the pitch.

6. To adjust pitch, start the tractor and raise the deck to

the highest possible position and turn off the engine.

7. Loosen the jam nuts on the bop or bottom of the height-

of-cut chain U bolt.

8. Adjust the other set of nuts to raise or lower the rear of

the No. 3 chamber and attain the correct deck pitch.

9. Tighten the jam nut.

10. Lower the deck.
