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 lawn mower. 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 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
working 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;
– ##incorrect hitching and load distribu-
tion.
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 ignition until petrol vapors have
dissipated.
• Replace all fuel tanks and container caps
securely.
4. Replace faulty silencers.
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 neu-
tral.
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 grass slopes requires particular
care. To guard against overturning:
• do not stop or start suddenly when going up
or downhill;
• engage the clutch slowly, and always keep
the machine in gear, especially when tra-
vailing downhill;
• machine speeds should be kept low on
slopes and during tight turns;
Safety

•stay alert for bumps and hollows and other
hidden hazards;
• never mow across the face of the slope,
unless the lawn mower is designed for this
purpose.
6. Use care when pulling loads or using heavy
equipment.
• Use only approved drawbar hitch points.
• Limit loads to those you can safely control.
• Do not turn sharply. Use care when revers-
ing.
• 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 dis-
charge of material toward bystanders nor allow
anyone near the machine while in operation .
10. Never operate the lawn mower with defective
guards, shields or without safety protective
devices in place.
11. Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speeds may increase the hazard of per-
sonal 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 the drive to attachments when trans-
porting or not in use.
14. Stop the engine and disengage the drive to the
attachment
• before refueling;
• before removing the grass catcher;
• before making height adjustments unless the
adjustment can be made from the operator’s
position.
• before clearing blockages;
• before checking, cleaning or working on the
lawnmower;
• after striking a foreign object. Inspect the
lawnmower for damage and make repairs
before restarting and operating the equipment.
15. 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. Be careful during adjustment of the machine to pre-
vent entrapment of the fingers between moving
blades and fixed parts of the machine.
9. On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
10. When the machine is to be parked, stored or left
unattended, lower the cutting means unless a posi-
tive mechanical lock is used.

CHECKTHE ENGINE OIL DAILY
1. Park the machine on a level surface. Release the engine
cover latches (Fig. 1).
2. Open the engine cover and hold it upright
3. Remove the dipstick, wipe it clean, reinstall it into the fill
tube and pull it out again; the oil level should be up to the
FULL mark (Fig. 2).
4. If the oil is below the FULL mark, remove the fill cap (Fig.
3) and add SAE 10W-30 oil until the level reaches the
FULL mark. DO NOT OVERFILL. Crankcase capacity is
6.9 qt. (6.5 l) with the filter.
5. Install the oil fill cap and dipstick.
6. Close the engine cover and secure it with the latches.
CHECKTHE COOLING SYSTEM DAILY
Capacity of the system is 3.7 gal. (14 l).
1. Remove the radiator cap (Fig. 4). The coolant should be
one inch from the bottom of the fill hole.
2. If the coolant is low, add a 50/50 mixture of water and eth-
ylene glycol anti-freeze. DO NOT USE WATER ONLY
OR ALCOHOL/METHANOL BASE COOLANTS.
3. Install the radiator cap.
FILLTHE FUELTANK
1. Remove the fuel tank cap (Fig. 4).
2. Fill the tank to about one inch (25 mm) below the bottom
Before Operating
The best time to check the coolant level is before the
engine is started each day because it is not pressur-
ized. When the engine is hot, pressurized coolant can
escape and cause burns when the radiator cap is
removed. Remove the radiator cap slowly and care-
fully if the engine coolant is hot.
CAUTION

CHECKTHE HYDRAULIC SYSTEM
DAILY
1. Look into the sight glass (Fig. 5). The oil level should be
even with the arrows when checking warm oil. The oil
will be 64-127 mm (1/4 to 1/2) inches below the arrows
when cold.
2. If the oil level is low, add hydraulic oil to the reservoir.
Refer to Hydraulic Oil Specifications.
CHECKTHE REEL-TO-BEDKNIFE
CONTACT
Each day before operating, check the reel-to-bedknife contact,
regardless of whether the quality of cut had previously been
acceptable. There must be light contact across the full length
of the reel and bedknife.
CHECKTHETIRE PRESSURE DAILY
For normal mowing conditions and a variety of turf grasses,
use these tire pressures: 90 kPa (13 psi) front and 103 kPa (15
psi) rear. However, when the turf is either wetter or drier than
normal, you may need to change the tire pressure. On hard
turf, use high tire pressure 124kPa (18 psi) front and rear).
When turf is soft, use low pressure 62kPa front and 83 kPa
rear (9 psi front and 12 psi rear).
IMPORTANT: Maintain even pressure in the two front
tires and both rear tires to assure excellent quality of cut.
Do not exceed 16 kph (10 mph) transport speed (for
extended periods) when the tire pressure is 83kPa (12 psi)
or less because the tires may be damaged. Maximum
transport speed can be used when the front tire pressure is
higher than 90 kPa (13 psi).
Because diesel fuel is flammable, use caution when
storing or handling it. Do not smoke while filling the
fuel tank. Do not fill the fuel tank while the engine is
running, hot, or when the machine is in an enclosed
area. Always fill the fuel tank outside and wipe up
any spilled diesel fuel before starting the engine.
Store fuel in a clean, safety-approved container and
keep the cap in place. Use diesel fuel for the engine
only; not for any other purpose.

• For no load, maximum ground speed, fully press the
pedal while the throttle is in FAST.
• For maximum power under load or when going uphill,
keep the engine rpm high by having the throttle in FAST
and the traction pedal held stationary against the ground
speed limiter. If the engine rpm begins to decrease due to
load, gradually reduce the traction pedal pressure until
the engine speed increases.
To stop, reduce foot pressure on the traction pedal and
allow it to return to the center position. On extreme
downhill slopes, apply pressure to the REVERSE side of
the pedal, or operate with your heel on REVERSE and
your toe on FORWARD part of the pedal.

PRIMINGTHE FUEL SYSTEM
IMPORTANT: The fuel system must be primed when a new
engine is started for the first time, if it runs out of fuel or if
maintenance is done on the fuel system.
1. Raise the engine cover.
2. Loosen the fuel filter bleed plug one turn (Fig. 12). Push
the priming plunger (Fig. 12) until a steady stream of fuel
runs out of the hole in the plug. When the fuel stops foam-
ing, tighten the plug during the downstroke of the priming
plunger. Wipe up any spilled fuel.
Note: lt may be necessary to bleed the air out of the fuel
line between the fuel filter and the injection pump. To do
this, loosen the fitting on the injection pump and repeat the
bleeding procedure.
3. Normally the engine will now start. If the engine does not
start, loosen each injector fitting at the engine and crank
the engine until a steady stream of fuel runs out of the fit-
ting. Tighten the fitting when fuel foaming stops.

1. Apply the parking brake, turn the ignition key ON. Push
the warning indicator light button (Fig. 13). All lights
should illuminate and the alarm will sound.
Note: The alarm will continue to sound until the prob-
lem is corrected or until the alarm silence button is
pressed. If a second problem is encountered, the alarm
will not sound but the indicator light will illuminate.
CHECKINGTHE INTERLOCK SYSTEM
1. In a wide open area free of debris and bystanders, lower
the cutting units to the ground. Stop the engine.
2. Sit on the seat and engage the parking brake (Fig. 14).
Turn the key and try to start the engine with the Mow
Backlap lever (Fig. 14) in both the MOW and BACK-
LAP positions. If the engine cranks, there is a malfunc-
tion that must be repaired immediately. If the engine
does not crank, the cutter drive switch is operating cor-
rectly.
3. Sit on the seat and disengage the parking brake (Fig. 14).
Turn the key and try to start the engine with the Mow
Backlap lever (Fig. 14) in STOP. If the engine cranks,
there is a malfunction that must be repaired immediately.
If the engine doesn’t crank, the brake switch is operating
correctly.
4. Engage the parking brake (Fig. 14), start the engine and
lower the cutting units. Move the Mow-Backlap lever
(Fig. 14) to MOW. Rise off the seat; the engine should
stop within a few seconds, which indicates the interlock
system is operating. Also rise off the seat with the lever
in BACKLAP. The engine should stop, indicating the
interlock system is operating. If the engine does not stop,
there is a malfunction that must be repaired immediately.

THE INTERLOCK SWITCHES ARE FOR THE
OPERATOR’S PROTECTION, SO DO NOT DIS-
CONNECT THEM. CHECK SWITCH OPERA-
TION DAILY TO MAKE SURE THE INTER-
LOCK SYSTEM IS OPERATING. IF A SWITCH
IS DEFECTIVE, REPLACE IT BEFORE OPERAT-
ING. REGARDLESS OF WHETHER THE
SWITCHES ARE OPERATING CORRECTLY,
REPLACE THEM EVERY TWO YEARS TO
ASSURE MAXIMUM SAFETY

Note: There is a 1–2 second delay between rising off
the seat and the engine shuts off.
5. Engage the parking brake, move the Mow-Backlap
lever to NEUTRAL, start the engine, disengage the
hand brake and raise off the seat. If the engine stops,
the interlock system is operating. If the engine does
not stop, there is a malfunction that must be repaired
immediately.
PUSHING ORTOWINGTHETRAC-
TION UNIT
In an emergency, the traction unit can be pushed or towed
for a very short distance by using the traction pump by-pass
valve.
IMPORTANT: Do not push or tow the traction unit
faster than 2 to 3 mph (3 to 5 km/hr) because the
hydraulic system may be damaged. If the traction unit
must be moved a considerable distance, transport it on a
truck or trailer.
1. Remove the retainer clip from the seat lock rod (Fig.
15)
2. Raise the seat and support it in an upright position with
the seat support rod (Fig. 16)
3. Lift and remove the front panel (Fig 17)
4. Turn the by-pass valve 90 degrees (Fig. 18). Opening
the valve opens an internal passage in the traction
pump, bypassing hydraulic oil.. Because the oil is by-
passed, the traction unit can be moved without damag-
ing the hydraulic system.
IMPORTANT: Make sure that the hand brake is
engaged before opening the by-pass valve.

The vehicle will roll with the front wheel motors
disengaged. The vehicle must be on a level surface
or the wheels must be blocked. There is no effec-
tive braking with the wheel motors disengaged.
CAUTION

5. Before starting the engine, close the by-pass valve. Do
not start the engine when the valve is open.
IMPORTANT: Running the machine with the bypass valve
open will cause the hydraulic system to overheat.
If towing with the front wheel motors disengaged, the Tow
Bar Assembly, Toro part no. 58-7020, must be used.
OPERATING CHARACTERISTICS
Familiarization—Before mowing grass, practice in an open
area. Start and stop the engine. Operate the machine in for-
ward and reverse. Lower and raise the cutting units simulta-
neously and individually. Engage and disengage the reels.
Operate with all cutting units down, then with only an individ-
ual cutting unit. When you feel familiar with the machine,
practice operating around trees and obstacles. Also drive up
and down slopes using both mowing and transport speeds.
Warning System—If a warning light comes on during opera-
tion, stop the machine immediately and correct the problem
before continuing operation. Serious damage could occur if
you operate the machine when it has a malfunction. For short
intervals, however, you can use the emergency engine over-
ride button (Fig. 11) to operate the engine if it stops because
of overheating.
Mowing—When you are at the area to be mowed, release the
front cutting unit transport latch, center latch and outside
latches. Lower the cutting units, engage the hand brake and
stop the engine.
Cutting Unit Grass Deflectors—Adjust the grass deflectors
to the horizontal position (Fig. 19), so grass clippings disperse
backward; out and away from the cutting units. This will pre-
vent clumps of grass clippings—especially wet grass clip-
pings—dropping off the machine or cutting units, which
affects the turf’s appearance.
Note: Generally you can adjust the deflectors down slightly in
dry grass and up slightly in wet grass.
While checking the speedometer, match the ground speed lim-
iter (Fig. 20) and the reel speed control knob (Fig. 21) to the
desired height-of-cut: refer to the cutting Charts (Fig. 22).
Use the decal at side of steering column as a guide only.
Cross Cut Link—When engaging/disengaging the center lift
control lever, the cross-cut link will simultaneously
engage/disengage the mow control lever to eliminate the need
for two separate hand operations. If the mow control lever
