Table of Contents

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 regulations

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 responsible

for accidents or hazards occurring to other people or

their property.

5. Do not carry passengers.

6. All drivers should seek and obtain professional and

practical instruction. Such instruction should empha-

size:

• the need for care and concentration when work-

ing with ride-on 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.

• 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 are

of spillage and avoid creating any source of igni-

tion until petrol vapors have dissipated.

• Replace all fuel tanks and container caps secure-

ly.

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 collect.

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.

Safety

Travel on grass 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 and

during tight turns;

• stay alert for bumps and hollows and other hid-

den 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

suggested 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;

• 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 enclo-

sure.

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 dete-

rioration.

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 positive

mechanical lock is used.

Cutter Housing: Both cutter housings are made from 11-gauge (13

mm) steel and reinforced with 89 mm x 4.76 mm channel iron .

Cutting Unit Drive: The gear box is driven by the PTO shaft.

Power is transmitted to the blades by three B-section belts. The

spindle shafts are 32 mm in diameter and supported by two exter-

nally sealed, greaseable, tapered roller bearings.

Cutting Unit: Front-mounted cutting units have front and rear cast-

er wheels, three heat-treated steel blades 0.63 m long and 6 mm

thick.

Caster Wheels: Two front caster wheels have roller bearings with

260.4 mm x 82.55 mm hard rubber tires. The rear wheels have

roller bearings and 152.8 mm x 63.5 mm hard rubber tires.

Blade Tip Speed: At 3200 engine rpm, blade tip speed is 76.2

m⁄sec.

Cutting Unit Lift: Cutting units are lifted by a hydraulic cylinder

that has 64 mm bore and 82 mm stroke.

Dimensions and Weights:

Model 30722 Width: 85-1⁄2 in. (2.17 m)

Weight: 400 lb (181.4 Kg)

Model 30710 Width: 76 in. (1.93 m)

Weight: 415 lb (188.2 Kg)

CHECKTHE LEVEL OF LUBRICANT IN

THE GEAR BOX

The gear box is designed to operate on SAE 80-90 weight gear

lube. Although the gear box is shipped with lubricant from the fac-

tory, check the level before operating the cutting unit.

1. Position the machine and cutting unit on a level surface.

Lower the cutting unit onto the level surface.

Specifications

Before Operating

2. Remove the check plug from the side of the gear box (Fig 15)

and make sure the lubricant is up to the bottom of the hole. If

the level of lubricant 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

The height of cut is adjustable from 25 to 102 mm in 13 mm incre-

ments, by adding or removing an equal number of spacers on the

front and rear caster forks. The height-of-cut chart below gives the

combinations of spacers to use for all height-of-cut settings.

Note: 6 mm spacers are available and can be ordered from your

Toro distributor by Toro Part No. 27-1040. (Quantity-8).

Note: A more optimum cutting appearance of the turf can be

achieved in the lower heights of cut by lowering the rear of the cut-

ting unit. Accomplish this by relocating the rear caster wheel axles

in the upper hole of the caster forks (Fig. 3). Replace the axles into

the lower caster fork holes for higher height-of-cut settings where

optimum cutting appearance is not required.

IMPORTANT: Do not attempt to cut off more than 25 mm of
