Safety
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 emphasize:
• the need for care and concentration when
working 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 san-
dals.
2. Thoroughly inspect the area where the equip-
ment 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
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 dam-
aged blades and bolts in sets to preserve bal-
ance.
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 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 grass9 slopes requires particu-

Safety

lar 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
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
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
roadways.
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 lawnmower 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
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 ignition key
• before cleaning blockages or unclogging
chute;
• 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 equip-
ment;
• if the machine starts to vibrate abnormally
(check immediately).
14. Disengage drive to attachments when transport-
ing or not in use.
15. Stop the engine and disengage drive to attach-
ment
• before refueling;
• before removing the grass catcher;
• before making height adjustment unless
adjustment 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

5
Safety
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
unattended, lower the cutting means unless a
positive mechanical lock is used.

Specifications

CHECK THE ENGINE OIL
The engine is shipped with 3.8 qt (3.6 l) of oil in the
crankcase; however, check the oil level before and
after you first start the engine.
1. Position the machine on a level surface.
2. Open the hood.
3. Remove the dipstick and wipe it with a clean
rag. Insert the dipstick into the tube and make
sure it is seated fully. Remove the dipstick and
check the level of oil (Fig. 1). If the oil level is
low, add enough oil to raise the level to the
FULL mark on the dipstick. Do not overfill
(Fig. 2).

2. Engine oil filter
3. Oil dr in plug
Note: If the level of oil is at the ADD mark on
the dipstick, add 1 pint (0.47 l) of oil and
recheck the level. Do not overfill.
4. The engine uses any high-quality 10W30 deter-
gent oil having the American Petroleum
Institute – API–”service classification” CD.
IMPORTANT: Check the level of oil ever 5
operating hours or dail . Change oil after
ever 50 hours of operation.

2. Check the level of coolant in the radiator. The
radiator should be filled to the top of the filler
neck and the expansion tank filled to between
the marks on its side.
3. If the coolant level is low, replenish the system.
DO NOT OV RFILL.
4. Install the radiator and expansion tank caps.
CHECK HYDRAULIC SYSTEM
FLUID
The hydraulic system was designed to operate on
any high quality detergent oil having the American
Petroleum Institute–API–“service classification” SF,
CC or CD. Oil viscosity—weight—must be selected
according to anticipated ambient temperature.
Temperature/viscosity recommendations are:

Automatic Transmission Fluid
Note: Do not mix engine oil and automatic transmis-
sion fluid or hydraulic component damage may
result. When changing fluids, also change transmis-
sion filter. DO NOT US D XRON II ATF.
The axle housing acts as the reservoir for the system.
The transmission and axle housing are shipped from
the factory with approximately 5 quarts (4.7 l) of
SA 10W–30 engine oil. However, check the level
of transmission oil before the engine is first started
and daily thereafter.
1. Position the machine on a level surface. Place
all controls in their neutral position and start the
engine. Run the engine at lowest possible RPM
to purge the system of air. DO NOT NGAG
TH PTO. Turn the steering wheel several
times fully to the left and right. Raise the cut-
ting unit to extend the lift cylinders, aiming
steering wheels straight forward and stop the
engine.
2. Remove the dipstick cap (Fig. 5) from filler
neck and wipe it with a clean cloth. Screw the
dipstick cap finger-tight onto filler neck; then
remove it and check the level of fluid. If the
level is not within 1/2 inch (13 mm) from the
groove in the dipstick (Fig. 5), add SA
10W–30 engine oil, or, if used, automatic trans-
mission fluid to raise the level to groove mark.
Do not overfill.
IMPORTANT: When adding transmission
fluid to the h draulic s stem, use a funnel
with a fine wire screen—200 mesh or finer—
and make sure funnel and transmission fluid
are immaculatel clean. This procedure pre-
vents accidental contamination of the
h draulic s stem.
11
Before Operating
If the engine has been running, pressurized hot
coolant can escape and cause burns when the
radiator cap is removed.
CAUTION

3. Thread the dipstick fill cap finger-tight onto
filler neck. It is not necessary to tighten cap
with a wrench.
4. Check all hoses and fittings for leaks.
FILL THE FUEL TANK
The engine runs on No. 2-D or 1-D automotive type
diesel fuel with a minimum cetane rating of 40.
Note; Higher cetane rated fuel may be required if
the machine is to be used at high altitude and low-
atmospheric temperatures.
Use No. 2-D diesel fuel at temperatures above 20° F
(–7° C). and No. 1-D diesel fuel below 20° F (–7°
C). Use of No. 1-D diesel fuel at lower temperatures
provides lower flash point and pour point character-
istics, therefore easing startability and lessening
chances of chemical separation of the fuel due to low
temperatures (wax appearance, which may plug fil-
ters).
Use of No. 2-D diesel fuel above 20° F (–7° C) will
contribute toward longer life of the pump compo-
nents. Do not use furnace oil.
Store fuel outside of buildings in a convenient loca-
tion. Tipping the front of the tank up slightly will
allow contaminants to collect at the lower end away
from the outlet. Never empty the tank below 4 in.
(10 cm) from the bottom of the tank to avoid picking
up water and other contaminants that may have col-
lected at the bottom. ither filter the remainder at
the bottom through a chamois or dispose of it peri-
odically to prevent excessive build-up of contami-
nants.
Keep all fuel containers free of dirt, water, scale and
other contaminants. Many engine difficulties can be
traced to contaminants in the fuel.
Use only metal containers for fuel storage. DO NOT
store the fuel in a galvanized metal container. A
chemical reaction will result, which will plug the fil-
ters and cause possible fuel system damage.
If possible, fill the fuel tank at the end of each day.
This will prevent possible buildup of condensation
inside the fuel tank, preventing possible engine dam-
age. Allow the engine to thoroughly cool down
before refueling.
1. Using a clean cloth, clean the area around the
fuel tank cap.
2. Remove cap from the fuel tank (Fig. 6) and fill
the 8 gallon (34 l) tank to within 1 inch (25
mm) from the top with diesel fuel. Install fuel
tank cap tightly after filling tank.
Before Operating
12
Because diesel fuel is flammable, use caution
when storing or handling it. Do not fill the fuel
tank while the engine is running, hot or when
the machine is in an enclosed area. Vapors may
build up and be ignited by a spark or flame
source many feet away. DO NOT SMOK
while filling the fuel tank to prevent the possi-
bility of an explosion. Always fill the fuel tank
outdoors and wipe up any spilled diesel fuel
before starting the engine. Use a funnel or
spout to prevent spilling diesel fuel and fill the
tank to about 25 mm below the filler neck.
Store diesel fuel in a clean, safety-approved
container and keep the cap in place on the con-
tainer. Keep diesel in a cool, well-ventilated
place; never in an enclosed area such as a hot
storage shed. To assure volatility and to prevent
contamination, do not buy more than a 6-month
supply.
DANGER

1. Fuel t nk c p
Four-Wheel Drive Models Only:
Check Rear Axle Lubricant
The rear axle has three separate reservoirs which use
SA 80W-90 gear lub. Although the axle is shipped
with lubricant from the factory, check the level
before operating the machine.
1. Position the machine on a level surface.
2. Remove a check plug from each end of the axle
and make sure lubricant is up to the bottom of
the hole. If the level is low, remove one of the
mounting bolts above each end plug and add
enough lubricant to bring the level up to the
bottom of the hole (Fig. 7).
3. Remove the plug in the center of the axle and
check the level. If the level is low, add enough
lubricant to bring the level up to the bottom of
the hole.
4. To make sure that the cavities at each end of the
axle tube are filled, jack up each side of the axle
6 inches. Then with the axle level, check the
level at the center plug hole.

Before Operating

Service Brakes (Fig. 8 )—The left and right brake
pedals are connected to the left and right front
wheels. Since both brakes work independently of
each other, the brakes can be used to turn sharply or
to increase traction if one wheel tends to slip while
operating on certain slope conditions. However, wet
grass or soft turf could be damaged when the brakes
are used to turn sharply. To make a “quick-stop”,
depress both brake pedals together. Always lock the
brakes together when transporting the traction unit.
Figure 8
1. P rking br ke knob
2. Right br ke ped l
3. Left br ke ped l
Parking Brake—Whenever the engine is shut off,
the parking brake must be engaged to prevent acci-
dental movement. To engage the parking brake, push
lock arm (Fig. 9) on left brake pedal so that it locks
together with the right pedal. Next, push down fully
on both pedals and pull the parking brake knob out
(Fig. 8) then release the pedals. To release the park-
ing brake, depress both pedals until the parking
brake knob retracts. Before starting the engine, how-
ever, the lock arm may be disengaged from the left
brake pedal so both pedals work independently with
each front wheel.
Amp Light (Fig. 10)—The amp light should be off
when the engine is running. If it is on, the charging
system should be checked and repaired if necessary.
Hour Meter (Fig. 10)—Accumulated engine operat-
ing time registers on the hour meter.

Temperature Gauge and High Temperature Light
(Fig. 10)—The coolant temperature gauge registers
the coolant temperature in the system. If the temper-
ature gets too high, the engine will automatically
shut off and the High Temperature shutoff light will
light. When this happens, turn the ignition key off,
check the radiator for debris, check the fan belt and
check the expansion tank for proper coolant level.
The high temperature shutoff will automatically reset
when the coolant temperature has reached a safe
level.

to begin operation.
Ignition Ke Switch (Fig. 10)—The ignition
switch, which is used to start and stop the engine,
has three positions: OFF, RUN and START. Turn the
key clockwise—START position—to engage the
starter motor. Release the key when the engine starts.
The key will move automatically to the ON position.
To shut the engine off, turn the key counterclockwise
to the OFF position.
Glow Plug Switch and Indicator (Fig. 10)—Use to
preheat the engine cylinders prior to cold engine
starting procedures—cylinders are preheated auto-
matically during warm engine start operation. For
cold starting, push the switch lever upward and hold
while viewing the indicator. The indicator will glow
orange when the glow plugs are activated. Length of
time necessary to preheat cylinders should be deter-
mined by atmospheric temperature.
Throttle (Fig. 10)—The throttle is used to operate
the engine at various speeds. Moving the throttle
forward increases engine speed—FAST; rearward
decreases engine speed—SLOW. The throttle con-
trols the speed of the cutter blades and, together with
traction pedal, controls the ground speed of the trac-
tion unit.
H draulic Lift Lever (Fig. 10)—The hydraulic lift
lever has three positions: FLOAT, TRANSPORT and
RAIS . To lower the cutting unit to the ground,
move the lift lever forward into the notch FLOAT.
The FLOAT position is used for mowing and when
the machine is not in operation. To raise the cutting
unit, pull the lift lever rearward to the RAIS posi-
tion. After the cutting unit is raised, allow the lift
lever to move to the TRANSPORT position. The
cutting unit must be raised when driving from one
work area to another.
Traction Pedal (Fig. 11 )—The traction pedal has
two functions: one is to make the machine move for-
ward, the other is to make it move rearward. Using
the heel and toe of the right foot, depress the top of
the pedal to move forward and the bottom of the
pedal to move rearward. Ground speed is proportion-
ate to how far pedal is depressed. For maximum
ground speed, the traction pedal must be fully
depressed while the throttle is in the FAST position.
Maximum speed forward is 10 mph (16 Km/hour).
To get maximum power under heavy load or when
ascending a hill, have the throttle in the FAST posi-
tion while depressing the traction pedal slightly to
keep engine rpm high. When engine rpm begins to
decrease, release the traction pedal slightly to allow
rpm to increase.

CAUTION

STARTING/STOPPING THE
ENGINE
IMPORTANT: The fuel s stem must be bled if
an of the following situations have occurred.
A. Initial start up of a new machine.
B. The engine has ceased running due to lack of
fuel.
C. Maintenance has been performed upon fuel sys-
tem components; i.e., filter replaced, separator
serviced, etc.
Refer to Bleeding The Fuel S stem.
1. nsure the parking brake is set, the PTO switch
is in OFF and the lift lever is in the TRANS-
PORT or FLOAT position (Fig. 9). Remove
your foot from the traction pedal and make sure
it is in neutral.
2. Move the throttle control (Fig. 9) to the full
FAST position.
3. When temperature is below 15°C (60° F), push
glow plug switch to ON (Fig. 9) and hold for
the suggested interval.
Note: Do not exceed 1 minute of continuous
use or glow plug may burn out prematurely.
Note: Refer to chart indicating approximate
preheat time suggested in various temperature
ranges.
Temperature Preheat time (sec)
Above 5° C 10
+5° C to –5° C 20
Below –5° C 30
4. Turn the key in ignition switch to START posi-
tion (Fig. ). Release the key immediately when
the engine starts and allow it to return to RUN
position. Move the throttle control to the SLOW
position.
Note: Do not run the starter motor more than
20 seconds at a time or premature starter failure
may result. If the engine fails to start after 20
seconds, turn the key to OFF, recheck the con-
trols and procedures, wait 10 additional seconds
and repeat the starter operation.
5. When the engine is started for the first time, or
after the engine oil change or overhaul of the
engine, transmission or axle, operate the
machine in forward and reverse for one to two
minutes. Also operate the lift lever and PTO
lever to assure proper operation of all parts.
Turn the power steering wheel to the left and
right to check steering response. Then shut the
engine off and check fluid levels, check for oil
leaks, loose parts and any other noticeable mal-
functions.
6. To stop the engine, move the throttle control
backward to SLOW, move the PTO switch to
OFF and turn the ignition key to OFF. Remove
the key from the switch to prevent accidental
starting.
BLEEDING THE FUEL SYSTEM
1. Raise the hood over the engine.
2. Loosen the air bleed screw on top of the fuel fil-
ter/water separator (Fig. 12).
3. Turn the ignition key switch to RUN. The elec-
tric fuel pump will begin operation, thereby
forcing air out around air bleed screw. Leave the
key in the RUN position until a solid stream of
fuel flows out around screw. Tighten the screw
and turn the key to OFF.
16
Operation
Shut the engine off and wait for all moving
parts to stop before checking for oil leaks,
loose parts or other malfunctions.

5. Turn the key to the RUN position. The electric
fuel pump will begin operation, thereby forcing
air out around air bleed screw on fuel injection
pump. Leave the key in the RUN position until
solid stream of fuel flows out around the screw.
Tighten the screw and turn the key to OFF.
CHECKING THE INTERLOCK
SAFETY SYSTEM
The purpose of the safety interlock system is to pre-
vent the engine from cranking or starting unless the
traction pedal is in neutral and the PTO switch is in
the OFF position. Also, the engine will stop when
the PTO control is engaged or the traction pedal is
depressed with the operator off the seat.
1. Move the PTO switch to OFF and remove your
foot from the traction pedal so it is fully
released.
2. Turn the key to START. The engine should
crank. If the engine cranks, go to step 3. If the
engine does not crank, there may be a malfunc-
tion in the interlock system.
3. Rise from the seat and engage the PTO switch
while the engine is running. The engine should
stop within 2 seconds. If the engine stops, the
switch is operating correctly; thus, go to step 4.
If the engine does not stop, there is a malfunc-
tion in the interlock system.
4. Rise from the seat and depress the traction
pedal while the engine is running and the PTO
lever is disengaged. The engine should stop
within 2 seconds. If the engine stops, the switch
is operating correctly; thus, continue operation.
If the engine does not stop, there is a malfunc-
tion in the interlock system.
OPERATING
CHARACTERISTICS
Practice driving the GROUNDSMAST R®223-D
before initial operation because it has a hydrostatic
transmission and its characteristics are different than
some turf maintenance machines. Some points to
consider when operating the traction unit and cutting
unit are the transmission, engine speed, load on the
cutting blades, and the importance of the brakes.
To maintain enough power for the traction unit and
cutting unit while mowing, regulate traction pedal to
keep engine rpm high and somewhat constant. A
good rule to follow is: decrease ground speed as the
load on the cutting blades increases; and increase
17
Operation
Do not disconnect the safety switches because
they are for the operator’s protection. Check
operation of the switches daily to be sure the
interlock system is operating correctly. If a
switch is malfunctioning, replace it before oper-
ating the machine. Replace the switches every
two years to be sure of maximum safety.
CAUTION

ground speed as the load on the blades decreases.
This allows the engine, working with the transmis-
sion, to sense the proper ground speed while main-
taining the high blade tip speed necessary for good
quality of cut. Therefore, let the traction pedal to
move upward as engine speed decreases, and depress
the pedal slowly as speed increases. By comparison,
when driving from one work area to another—with
no load and cutting unit raised—have the throttle in
the FAST position and depress the traction pedal
slowly but fully to attain maximum ground speed.
CAUTION: This product may exceed noise levels of
85 dB(A) at the operator position. ar protectors are
recommended for prolonged exposure to reduce the
potential of permanent hearing damage.
Another characteristic to consider is the operation of
the brakes. The brakes can be used to assist in turn-
ing the machine; however, use them carefully, espe-
cially on soft or wet grass because the turf may be
torn accidentally. The brakes can be used to great
advantage to control the direction of the cutting unit
when trimming along fences or similar objects.
Another benefit of the brakes is to maintain traction.
For example; in some slope conditions, the uphill
wheel slips and loses traction. If this situation
occurs, depress the uphill brake pedal gradually and
intermittently until the uphill wheel stops slipping,
thereby increasing traction on the downhill wheel. If
independent braking is not desired, engage the lever
on the left brake pedal with right pedal. This pro-
vides simultaneous braking at both wheels.
Before stopping the engine, disengage all controls
and move the throttle to SLOW. Moving the throttle
to SLOW reduces high engine speed, noise and
vibration. Turn the ignition key to OFF to stop the
engine.
PUSHING OR TOWING THE
TRACTION UNIT
In an emergency, the traction unit can be pushed or
towed for a very short distance. However, Toro does
not recommend this as standard procedure.
IMPORTANT: Do not push or tow the traction
unit faster than 2 to 3 mph (3.2 to 4.8 Km/hour)
because transmission ma be damaged. If the
traction unit must be moved a considerable dis-
tance, transport it on a truck or trailer. Whenever
the traction unit is pushed or towed, the b -pass
valve must be open.
1. Remove the hair pin and pivot the seat platform
forward and locate seat support rod in the detent
notch.
2. Depress and hold the pins located in the center
of the two (2) check valve assemblies in the top
of the transmission (Fig. 14) while pushing or
towing the machine.
Figure 14
1. Tr nsmission check v lve byp ss pins (2)
3. Start the engine momentarily after repairs are
completed and make sure the pins are in the
fully disengaged (fully up) position.
IMPORTANT: Running the machine with b -pass
valve open will cause the transmission to over-
heat.
Operation
18
Adequate rear weight is necessary to prevent the
rear wheels from leaving the ground. Do not
stop suddenly while cutting unit or implement is
raised. Do not travel down hill with the cutting
unit or implement raised. If the rear wheels
leave the ground, steering is lost.
CAUTION

LUBRICATION
GREASING BEARINGS AND BUSHINGS
The traction unit has grease fittings that must be
lubricated regularly with No. 2 General Purpose
Lithium Base Grease. If the machine is operated
under normal conditions, lubricate all bearings and
bushings after every 50 hours of operation or imme-
diately after every washing. Bearings and bushings
must be lubricated daily when operating conditions
are extremely dusty and dirty. Dusty and dirty oper-
ating conditions could cause dirt to get into the bear-
ings and bushings, resulting in accelerated wear.
Apply a liberal coating of grease to the check valve
pins once each year (Fig. 14). The traction unit has
bearings and bushings that must be lubricated, and
these lubrication points are shown in the following
figures.
1. Wipe grease fitting clean so foreign matter can-
not be forced into the bearing or bushing.
2. Pump grease into the bearing or bushing.
3. Wipe up excess grease.
