Safe Operating Practices
The following instructions are from the CEN standard EN
836:1997, ISO standard 5395:1990, and ANSI B71.4-2004.
Training
• Read the operator’s manual and other training material
carefully. Be familiar with the controls, safety signs,
and the proper use of the equipment.
• Never allow children or people unfamiliar with these
instructions to use or service the mower. Local
regulations may restrict the age of the operator.
• Never mow while people, especially children, or pets
are nearby.
• Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
• Do not carry passengers.
• All drivers and mechanics should seek and obtain
professional and practical instruction. The owner is
responsible for training the users. 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;
3
Page 4
• inadequate braking;
• the type of machine is unsuitable for its task;
• lack of awareness of the effect of ground
conditions, especially slopes;
• incorrect hitching and load distribution.
• The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people, or property.
Preparation
• While operating machine, always wear substantial
footwear, long trousers, hard hat, safety glasses, and ear
protection. Long hair, loose clothing, or jewelry may
get tangled in moving parts. Do not operate the machine
when barefoot or wearing open sandals.
• Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
• Warning—Fuel is highly flammable. Take the
following precautions:
– Store fuel in containers specifically designed for this
purpose.
– Refuel outdoors only and do not smoke while
refuelling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel while the engine
is running or when the engine is hot.
– If fuel 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 fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Replace faulty silencers/mufflers.
• Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments approved
by the manufacturer.
• Check that operator’s presence controls, safety switches
and shields are attached and functioning properly. Do
not operate unless they are functioning properly.
• Before attempting to start the engine, disengage all
blade attachment clutches, shift into neutral, and engage
the parking brake.
• 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 clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
mower is designed for this purpose.
• Stay alert for holes in the terrain and other hidden
hazards.
• 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 reversing.
– Use counterweight(s) or wheel weights when
suggested in the operator’s manual.
• Watch out for traffic when crossing or near roadways.
• Stop the blades rotating before crossing surfaces other
than grass.
• When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards,
shields, or without safety protective devices in place. Be
sure all interlocks are attached, adjusted properly, and
functioning properly.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at excessive
speed may increase the hazard of personal injury.
• Before leaving the operator’s position:
– stop on level ground;
Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Mow only in daylight or in good artificial light.
– disengage the power take-off and lower the
attachments;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
• Disengage drive to attachments when transporting or
not in use.

Page 5
• Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher/catchers;
– before making height adjustment unless adjustment
can be made from the operator’s position.
– before clearing blockages;
– before checking, cleaning or working on the mower;
– after striking a foreign object or if an abnormal
vibration occurs. Inspect the mower for damage and
make repairs before restarting and operating the
equipment.
• Reduce the throttle setting during engine run-out and, if
the engine is provided with a shut-off valve, turn the
fuel off at the conclusion of mowing.
• Keep hands and feet away from the cutting units.
• Look behind and down before backing up to be sure of
a clear path.
• To reduce the fire hazard, keep the engine,
silencer/muffler, battery compartment and fuel storage
area free of grass, leaves, or excessive grease.
• Check the grass catcher frequently for wear or
deterioration.
• Keep all parts in good working condition and all
hardware and hydraulic fittings tightened. Replace all
worn or damaged parts and decals.
• If the fuel tank has to be drained, do this outdoors.
• Be careful during adjustment of the machine to prevent
entrapment of the fingers between moving blades and
fixed parts of the machine.
• On multi-cylinder/multi-reel machines, take care as
rotating one cylinder/reel can cause other
cylinders/reels to rotate.
• Disengage drives, lower the cutting units, set parking
brake, stop engine and remove key and disconnect spark
plug wire. Wait for all movement to stop before
adjusting, cleaning or repairing.
• Slow down and use caution when making turns and
crossing roads and sidewalks. Stop cylinders/reels if not
mowing.
• Do not operate the mower under the influence of
alcohol or drugs
• Use care when loading or unloading the machine into a
trailer or truck
• Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
• This machine is not designed or equipped for on–road
use and is a “slow–moving vehicle.” If you must cross
or travel on a public road, you should be aware of and
comply with local regulations, such as required lights,
slow moving vehicle signs, and reflectors.
Warning
Engine exhaust contains carbon monoxide, which
is an odorless, deadly poison that can kill you.
Do not run engine indoors or in an enclosed area.
• Clean grass and debris from cutting units, drives,
silencers/mufflers, and engine to help prevent fires.
Clean up oil or fuel spillage.
• Use jack stands to support components when required.
• Carefully release pressure from components with stored
energy.
• Disconnect battery and remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last.
• Use care when checking the cylinders/reels. Wear
gloves and use caution when servicing them.
• Keep hands and feet away from moving parts. If
possible, do not make adjustments with the engine
running.
• Charge batteries in an open well ventilated area, away
from spark and flames. Unplug charger before

other hazards.
– Reduce speed when making sharp turns. Avoid
sudden stops and starts.
– When near or crossing roads, always yield the
right-of-way.
– Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
• The grass baskets must be in place during operation of
the cylinders/reels or thatchers for maximum safety.
Shut the engine off before emptying the baskets.
• Raise the cutting units when driving from one work
area to another.
• Do not touch the engine, silencer/muffler, or exhaust
pipe while the engine is running or soon after it has
stopped because these areas could be hot enough to
cause burns.
• Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units and attachments to the ground.
• Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
• If the engine must be running to perform a maintenance
adjustment, keep hands, feet, clothing, and any parts of
the body away from the cutting units, attachments, and
any moving parts, especially the screen at the side of the

• Stay clear of the rotating screen at the side of the engine
to prevent direct contact with your body or clothing.
• If the engine stalls or loses headway and cannot make it
to the top of a slope, do not turn the machine around.
Always back slowly, straight down the slope.
• When a person or pet appears unexpectedly in or near
the mowing area, stop mowing. Careless operation,
combined with terrain angles, ricochets, or improperly
positioned guards can lead to thrown object injuries. Do
not resume mowing until the area is cleared.
Maintenance and Storage
• Make sure all hydraulic line connectors are tight and all
hydraulic hoses and lines are in good condition before
applying pressure to the system.
• Keep your body and hands away from pin hole leaks or

Checking the Engine Oil
The engine is shipped with oil in the crankcase; however,
the oil level must be checked before the engine is first
started.
Crankcase capacity is approximately 8 qt. (7.6 L) with the
filter.
Use high-quality engine oil that meets the following
specifications:
API Classification Level Required: CH–4, CI–4 or
higher.
Preferred oil: SAE 15W–40 (above 0F)
Alternate oil: SAE 10W–30 or 5W–30
(all temperatures)
Toro Premium Engine oil is available from your distributor
in either 15W–40 or 10W–30 viscosity. See the parts
catalog for part numbers.

5. Install oil fill cap and dipstick.
Important Be sure to keep the engine oil level between
the upper and lower limits on the oil gauge. Engine failure
may occur as a result of over filling or under filling the
engine oil.
6. Close engine cover and secure with the latches.
Check Cooling System
Check level of coolant at the beginning of each day.
Capacity of system is 3.7 gal. (14 L).
1. Carefully remove radiator cap (Fig. 6) and expansion
tank cap (Fig. 5).
14
Page 15
Caution
If the engine has been running, pressurized hot
coolant can escape and cause burns if the radiator
cap is removed.
Allow the engine to cool at least 15 minutes or until
the radiator cap is cool enough to touch without
burning hands.
Biodiesel Ready
This machine can also use a biodiesel blended fuel of up to
B20 (20% biodiesel, 80% petrodiesel). The petrodiesel
portion should be low or ultra low sulfur. Observe the
following precautions:
• The biodiesel portion of the fuel must meet
specification ASTM D6751 or EN14214.
• The blended fuel composition should meet ASTM
D975 or EN590.
2. Check level of coolant in radiator. Radiator should be
filled to the top of the filler neck and the expansion tank
filled to the marks on its side
1
Figure 5
1. Expansion tank
3. If coolant is low, add a 50/50 mixture of water and
ethylene glycol anti–freeze. DO NOT USE WATER
ONLY OR ALCOHOL / METHANOL BASE
COOLANTS.
4. Install radiator cap and expansion tank cap.
Fill Fuel Tank
Use only clean, fresh diesel fuel or biodiesel fuels with low
(<500 ppm) or ultra low (<15 ppm) sulfur content. The
minimum cetane rating should be 40. Purchase fuel in
quantities that can be used within 180 days to ensure fuel
freshness.
Fuel tank capacity: 15 U.S. gallons (56.8 l)
• Painted surfaces may be damaged by biodiesel blends.
• Use B5 (biodiesel content of 5%) or lesser blends in
cold weather
• Monitor seals, hoses, gaskets in contact with fuel as
they may be degraded over time.
• Fuel filter plugging may be expected for a time after
converting to biodiesel blends.
• Contact your distributor if you wish for more
information on biodiesel
1. Remove fuel tank cap (Fig. 6).
2. Fill tank to about one inch (25 mm) below bottom of
filler neck with No. 2 diesel fuel. Then install cap.
Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
Use summer grade diesel fuel (No. 2–D) at temperatures
above 20 degrees F (–7 degrees C) and winter grade (No.
1–D or No. 1–D/2–D blend) below that temperature. Use of
winter grade fuel at lower temperatures provides lower
flash point and cold flow characteristics which will ease
starting and reduce fuel filter plugging.
Use of summer grade fuel above 20 degrees F (–7 degrees
C) will contribute toward longer fuel pump life and
increased power compared to winter grade fuel.

Checking the Hydraulic Fluid
The machines reservoir is filled at the factory with
approximately 18.2 U.S. gallons of high quality hydraulic
fluid. Check the level of the hydraulic fluid before theengine is first started and daily thereafter. The
recommended replacement fluid is:
Toro Premium All Season Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We do not
recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:
Toro will not assume responsibility for damage caused by
improper substitutions, so use only products from reputable
manufacturers who will stand behind their
recommendation.

Check Reel To Bedknife
Contact
Each day before operating, check reel to bedknife contact,
regardless if quality of cut had previously been acceptable.
There must be light contact across the full length of the reel
and bedknife (refer to Adjusting Cutting Units in Cutting
Unit Manual, Step #1 – Reel to Bedknife Adjustment).
Check Tire Pressure
For normal mowing conditions and a wide variety of turf
grasses, use these tire pressures: 13 psi front and 15 psi
rear. However, when turf is either wetter or drier than
normal, tire pressure may need to be changed. On hard
turf, use high tire pressure (18 psi front and rear). When
turf is soft, use low pressure (9 psi front and 12 psi rear).
Important Maintain even pressure in two front tires (ie.
13 psi) and both rear tires (ie 15 psi) to assure excellent
quality–of–cut.
Industry Specifications:
Vickers I–286–S (Quality Level), Vickers M–2950–S
(Quality Level), Denison HF–0
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order
part no. 44–2500 from your authorized Toro distributor.
Rear Ballast
This unit complies with the ANSI B71.4–2004 Standard
when rear tires are filled with calcium chloride and a rear
wheel weight kit (Part No. 11–0440) is installed.
Important If a puncture occurs in a tire with calcium
chloride, remove unit from turf area as quickly as possible.
To prevent possible damage to turf, immediately soak
affected area with water.

cutting unit drive switch is operating properly.
3. Sit on the seat and disengage the parking brake. Turn
key and try to start engine with Mow–Backlap lever in
STOP. If engine cranks, there is a malfunction that must
be repaired immediately. If engine does not crank, brake
switch is operating properly.
4. Engage parking brake, start engine and lower cutting
units. Move Mow–Backlap lever to MOW. Raise off the
seat; engine should stop within a few seconds, which
indicates the interlock system is operating. Also raise
off the seat with lever in BACKLAP. Engine should

Important Make sure that hand brake is engaged
before opening the by–pass valve.
4. Before starting engine, close by–pass valve. Do not start
engine when valve is open.
Important Running the machine with the by–pass
valve open will cause the hydraulic system to overheat.
Danger
Vehicle will roll with front wheel motors
disengaged. Vehicle must be on level surface or
wheels must be blocked. There is no effective
braking with wheel motors disengaged.
If towing, with front wheel motors disengaged,
Optional Tow Bar Assembly, Toro part no.

Operating Characteristics
When you are at the area to be mowed, release front, center
and outside cutting unit transport latches, lower cutting
units, engage hand brake and stop the engine.
Cutting Unit Grass Deflectors
Adjust grass deflectors to horizontal position (Fig. 20), so
clippings disperse backward; out and away from the cutting
units. This will prevent clumps of clippings, especially wet
clippings, dropping off the machine or cutting units, which
affects the visual appearance of the turf.
Note: Generally you can adjust the deflectors down slightly
in dry grass and up slightly in wet grass.
1
Figure 20
1. Grass deflector
Familiarization
Before mowing grass practice operating in an open area.
Start and stop the engine. Operate in forward and reverse.
Lower and raise cutting units simultaneously and
individually. Engage and disengage reels. Operate with all
cutting units down, then with only an individual 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.
Match the ground speed limiter (Fig. 21) and reel speed
control knob (Fig. 22) to desired height–of–cut: refer to
Cutting Chart (Fig. 23). Use decal at side of steering
column as a guide only.
Start engine and move throttle to FAST so engine is
running at maximum speed. Disengage hand brake. To
move forward, press traction pedal forward (Fig. 21). Move
Mow–Backlap lever to MOW. Reels are now spinning.
Maintain traction pedal contact with ground speed limiter
(Fig. 21) to assure consistent clip and quality–of–cut.

General Air Cleaner
Maintenance
• Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
• Service the air cleaner filter every 200 hours or earlier if
engine performance suffers due to extremely dusty,
dirty conditions. Changing the air filter before it is
necessary only increases the chance of dirt entering the
engine when the filter is removed.
new filter by applying pressure to the outer rim of the
element to seat it in the canister. Do not apply pressure
to the flexible center of the filter.
2
• Be sure the cover is seated correctly and seals with the
air cleaner body.
5. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the cover,
clean the cavity and replace the outlet valve.
6. Install the cover orienting the rubber outlet valve in a
downward position – between approximately 5:00 to
7:00 when viewed from the end. Secure latches.
Engine Oil And Filter
Change oil and filter after the first 50 hours of operation
and every 150 hours thereafter.
1. Remove drain plug (Fig. 30) and let oil flow into drain
pan. When oil stops, install drain plug.
2. Release latches securing air cleaner cover to air cleaner
body.
3. Remove the cover from the air cleaner body. Before
removing the filter, use low pressure air (40 psi, clean
and dry) to help remove large accumulations of debris
packed between outside of primary filter and the
canister. Avoid using high pressure air which could
force dirt through the filter into the intake tract. This
cleaning process prevents debris from migrating into
the intake when the primary filter is removed.
4. Remove and replace the primary filter. Cleaning of the
used element is not recommended due to the possibility
of damage to the filter media. Inspect the new filter for
shipping damage, checking the sealing end of the filter
and the body. Do not use a damaged element. Insert the

between the pulleys.
• If deflection is not 3/8 in. (10 mm), loosen alternator
mounting bolts. Increase or decrease alternator belt
tension and tighten bolts. Check deflection of belt
again to assure tension is correct.

Adding Hydraulic Oil
Capacity of the hydraulic reservoir is approximately 9.3
gal. (35.2 L).
With machine on a level surface, hydraulic oil level should
be 1/4 to 1/2 inch below arrows on sight glass, when oil is
cold. Warm oil should be even with arrows on sight glass
(Fig. 38). If level is low, add hydraulic oil.

Adjusting Hand Brake &
Traction Switches
In time, the hand brake cable may stretch, causing the
engine not to start. If this happens, adjust the cable
(Fig. 37).
1. Pull brake lever to 3rd click.
2. Pull brake lever up one additional click.
3. Adjust four U–bracket nuts equally so spring has
tension. Adjustment affects operation of traction
switches.
4. Adjust four U–bracket nuts so engine will start and run
when hand brake is at fourth click, but will not start or
run when hand brake is at second click.

After every 100 operating hours, drain water from
hydraulic reservoir. Before draining, allow machine to set
about 8 hours to allow water to settle to bottom of reservoir.
32
Page 33
1. Open drain plug (Fig. 40) one–half turn and allow fluid
to flow into drain pan until water is not noticed in
hydraulic oil.

Figure 40
1. Drain plug
2. Tighten drain plug and add hydraulic oil, Refer to
Adding Hydraulic Oil.
Changing Hydraulic Oil
1. Remove seat lock pin, raise seat and hold open with
support rod. Also remove panel (secured with magnets)
ahead of the seat.
2. Clean area around filter mounting area (Fig. 41). Place
drain pan under filter and remove filter.
3. Lubricate new filter gasket and fill the filter with
hydraulic oil.
4. Assure filter mounting area is clean. Screw filter on
until gasket contacts mounting plate. Then tighten filter
one–half turn.
5. Start engine and let it run slowly for about two minutes
to purge air from the system. Stop the engine and check
for leaks.
Normally, change hydraulic oil after every 2 years or 1600
operating hours. If oil becomes contaminated, contact your
local TORO distributor because the system must be
flushed. Contaminated oil looks milky or black when
compared to clean oil.
1. Remove drain plug (Fig. 40) from reservoir and let
hydraulic oil flow into drain pan. Tighten plug when
hydraulic oil stops draining.
2. Fill reservoir with approximately 9.3 gallons of
hydraulic oil. Refer to Checking the Hydraulic Oil.
Important Use only hydraulic oils specified. Other
fluids could cause system damage.
3. Install reservoir cover, lower seat and secure with lock
pin. Start engine, run slowly and use all hydraulic
controls to distribute hydraulic oil throughout the
system. Also check for leaks. Then stop the engine.
4. With cutting units up and oil warm, look into sight glass
(Fig. 38). If hydraulic oil is not even with arrows, add
enough to raise to proper level. Do not fill full if oil is
cold.
Replacing Hydraulic Filter
Initially, change filter after the first 50 operating hours,
thereafter, every 800 operating hours, annually, or on
indication.
1
Figure 41
1. Hydraulic Filter
6. Look into sight glass (Fig. 38). Hydraulic oil level
should be even with arrows when oil is warm. If level
is low, add hydraulic oil to the reservoir.
Note: Under certain conditions, a bypass valve in the filter
mounting plate allows oil to bypass the filter. Before the
filter starts to bypass a warning light on the steering
console will illuminate. The warning light may come on
momentarily when the oil is cold. If the light does not go
out after the oil is warm, the filter is clogged or an
electrical problem exists. Correct problem before
commencing operation.
Replacing Hydraulic System
Breather
Change hydraulic system breather after every 800
operating hours, or annually, whichever comes first. More
often in extremely dusty or dirty conditions.
1. Release latches and open engine cover.
Use Toro replacement filter (Part No. 86–6110).
Important Use of any other filter may void the
warranty on some components.
2. Clean around the breather and unscrew it with a wrench
(Fig. 42). Install new breather.

Battery Care
Warning
Warning
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Important Before welding on a machine, disconnect
both cables from the battery, disconnect both wire harness
plugs from the electronic control unit and the terminal
connector from the alternator to prevent damage to the
electrical system.
Warning
Battery terminals or metal tools could short
against metal tractor components causing sparks.
Sparks can cause the battery gasses to explode,
resulting in personal injury.
• When removing or installing the battery, do not
allow the battery terminals to touch any metal
parts of the machine.
• Do not allow metal tools to short between the
battery terminals and metal parts of the
machine.
Incorrect battery cable routing could damage the
tractor and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
Note: Check battery condition weekly or after every 50
hours of operation. Keep terminals and entire battery case
clean because a dirty battery will discharge slowly. To clean
the battery, wash the entire case with solution of baking
soda and water. Rinse with clear water. Coat the battery
posts and cable connectors with Grafo 112X (skin-over)
grease (Toro Part No. 505-47) or petroleum jelly to prevent
corrosion.
Danger
Battery electrolyte contains sulfuric acid which is a
deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact with
skin, eyes or clothing. Wear safety glasses to
shield your eyes and rubber gloves to protect
your hands.
• Fill the battery where clean water is always
available for flushing the skin.
