Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
Safety
Improper use or maintenance by the operator or owner
can result in injury. To reduce the potential for injury,
comply with these safety instructions and always pay
attention to the safety alert symbol, which means
CAUTION, WARNING, or DANGER—“personal
safety instruction.” Failure to comply with the
instruction may result in personal injury or death.
Safe Operating Practices
The following instructions are from ANSI standard
B71.4—2004.
Training
•Read the Operator’s Manual and other training material.
If the operator(s) or mechanic(s) can not read English it
is the owner’s responsibility to explain this material to
them.
•Become familiar with the safe operation of the
equipment, operator controls, and safety signs.
•All operators and mechanics should be trained. The
owner is responsible for training the users.
•Never let children or untrained people operate or
service the equipment. Local regulations may restrict
the age of the operator.
•The owner/user can prevent and is responsible for
accidents or injuries occurring to himself or herself,
other people or property.
Preparation
•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.
•Wear appropriate clothing including hard hat, safety
glasses and hearing protection. Long hair, loose
clothing or jewelry may get tangled in moving parts.
•Inspect the area where the equipment is to be used and
remove all objects such as rocks, toys and wire which
can be contacted by the aerator.
•Use extra care when handling gasoline and other fuels.
They are flammable and vapors are explosive.
•Use only an approved container
•Never remove gas cap or add fuel with engine
running. Allow engine to cool before refueling.
Do not smoke.
•Never refuel or drain the aerator indoors.
•Check that operator’s presence controls, safety switches
and shields are attached and functioning properly. Do
not operate unless they are functioning properly.
Operation
•Never run an engine in an enclosed area.
•Only operate in good light, keeping away from holes
and hidden hazards.

4
•Be sure all drives are in neutral and parking brake is
engaged before starting engine. Start the engine only
from the operator’s position.
•Never operate without the shields, covers or other
guards securely in place. Be sure all interlocks are
functioning properly.
•Keep hands and feet away from the nozzle and roller
area. High velocity water jets can penetrate hands and
feet. Penetration by the high velocity water jets can
cause serious personal injury. If accidental penetration
occurs, seek medical attention immediately.
•Never use chemicals in the water supply system.
•Do not operate the water injection system on concrete
or asphalt because water jets will permanently damage
these surfaces.
•Before disconnecting or performing any work on the
water system, all pressure in the system must be
relieved by stopping the engine and opening the bleed
valve. Opening the bleed valve allows any trapped
water to escape from the system and also allows the
accumulator piston to move to the bottom of the
accumulator cylinder.
•Do not change the engine governor setting or overspeed
the engine.
•The accumulator in this machine contains high pressure
dry nitrogen. Accumulator servicing requires special
tools and precautions. Accumulators do not contain user
serviceable components. Improper accumulator
servicing can cause dismemberment or death. Do not
attempt to disassemble an accumulator; have this work
done by an Authorized Toro Distributor.
•Stop on level ground, disengage drives, engage parking
brake, shut off engine before leaving the operator’s
position for any reason.
•Never carry passengers and keep pets and bystanders
away.
•Be alert, slow down and use caution when making
turns. Look behind and to the side before changing
directions.
•Slow down and use caution when crossing roads and
sidewalks.
•Do not operate the aerator under the influence of
alcohol or drugs.
•Use extreme care when loading or unloading the aerator
into a trailer or truck.
•Use care when approaching blind corners, shrubs, trees,
or other objects that may obscure vision.
Slope Operation
•Do not operate near drop–offs, ditches, steep banks or
water. Wheels or rollers dropping over edges can cause
rollovers, which may result in serious injury or death.
•Do not operate on slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding and
loss of control.
•Do not make sudden turns or rapid speed changes.
•Reduce speed and use extreme caution on slopes.
•Remove or mark obstacles such as rocks, tree limbs,
etc. from the operating area. Tall grass can hide
obstacles.
•Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the aerator.
•Be aware that loss of traction may occur going
downhill. Weight transfer may cause drive wheel to slip
and cause loss of braking and steering.
•Always avoid sudden starting or stopping on a slope. If
tire loses traction, disengage the water injection system
and proceed slowly off the slope.
Maintenance and storage
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.
Warning
•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
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury. Seek immediate medical attention if fluid is
injected into skin.
•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 deck
and attachments to the ground.
•Let engine cool before storing and do not store near
flame.
•Shut off fuel while storing or transporting on trailers.
Do not store fuel near flames or drain indoors.

5
•Park machine on level, hard ground. Never allow
untrained personnel to service machine.
•Use jack stands or safety latches to support components
when required.
•Carefully release pressure from components with stored
energy.
•Disconnect battery or remove spark plug wire before
making any repairs. Disconnect the negative terminal
first and the positive last. Reconnect positive first and
negative last.
•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
connecting or disconnecting from battery. Wear
protective clothing and use insulated tools.
•Keep all parts in good working condition and all
hardware tightened. Replace all worn or damaged
decals.
•Use only Toro-approved attachments. Warranty may be
voided if used with unapproved attachments.

Before Operating
Activating and Charging the
Battery
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.
Warning
1. Since the battery is not filled with electrolyte or
activated, bulk electrolyte with 1.260 specific gravity
must be purchased from a local battery supply outlet.
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.
2. Release the hood latches and raise the hood.
3. Loosen the capscrew securing the battery clamp to the
machine and remove the battery (Fig. 2). Remove the
filler caps from the battery and slowly fill each cell until
electrolyte is just above the plates.
Battery terminals or metal tools could short
against metal aerator 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 aerator.
•Do not allow metal tools to short between the
battery terminals and metal parts of the aerator.
Warning

Figure 2
1. Battery
4. Replace the filler caps and connect a 3 to 4 amp battery
charger to the battery posts. Charge the battery at a rate
of 3 to 4 amperes for 4 to 8 hours.
Charging the battery produces gasses that can
explode.
Never smoke near the battery and keep sparks and
flames away from battery.
Warning
5. When the battery is charged, disconnect the charger
from the electrical outlet and battery posts.
6. Remove the filler caps. Slowly add electrolyte to each
cell until the level is up to the fill ring. Install the filler
caps.
Important Do not overfill the battery. Electrolyte will
overflow onto other parts of the machine and severe
corrosion and deterioration will result.
7. Install the battery and secure it with the battery clamp.
Incorrect battery cable routing could damage the
aerator 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.
Warning

14
8. Install the positive cable (rubber boot over end) to the
positive (+) terminal and the negative cable (black) to
the negative (–) terminal of the battery and secure them
with capscrews and nuts. Slide the rubber boot over the
positive terminal to prevent a possible short-out from
occurring (Fig. 2).
9. Lower the hood and secure the latches.
Checking the Engine Oil
The engine is shipped with oil in the crankcase; however,
the oil level must be checked before and after the engine is
first started.
Crankcase capacity is approximately 2 qt. (1.4 l) with the
filter.
Use high-quality engine oil that meets the following
specifications:
API Classification Level Required: SJ, SK, SL or
higher.
Preferred oil: SAE 10W–30 (above 0_F)
Alternate oil: SAE 5W–30 (below 32_F)
Toro Premium Engine oil is available from your distributor
in 10W–30 viscosity. See the parts catalog for part
numbers.
1. Position the machine on a level surface.
2. Remove the dipstick from the oil filler neck (Fig. 3) and
wipe it with a clean rag. Insert the dipstick into the filler
neck and make sure it is seated fully. Pull the dipstick
from the filler neck and check the oil level. If the oil
level is low, add enough oil to raise the level to the
FULL mark on the dipstick.
1
2
Figure 3
1. Dipstick 2. OIl fill cap
Note: If the oil level is at the ADD mark on the dipstick,
add 1 quart of oil to raise the oil level to FULL. Do not
overfill.
3. Remove the cap from the oil fill. Pour oil into the oil fill
until the level is at the FULL mark on the dipstick.
Important The aerator operates at very high engine
loads, so check the oil level every 8 operating hours or
daily. A new engine may consume some oil until it is
broken in. Initially, change the oil after the first 25 hours of
operation; thereafter, under normal conditions, change the
oil and filter after every 100 hours of operation. Change the
oil more frequently when the engine is operated in
extremely dusty or dirty conditions.
Filling the Gas Tank
We recommend the use of fresh, clean, unleaded regular
grade gasoline. Unleaded gasoline burns cleaner, extends
engine life, and promotes good starting by reducing the
build-up of combustion chamber deposits.
Note: Do not mix oil with the gasoline. Never use
methanol, gasoline containing methanol, gasohol, gasoline
additives, premium gasoline, or white gas because engine
and fuel system damage could result.
1. Remove the cap from the fuel tank (Fig. 4) and fill the
10 gallon tank to about 1 inch (25 mm) from the top of
tank (the bottom of the filler neck) with unleaded
gasoline. Install the fuel tank cap tightly.
1
Figure 4
1. Fuel tank cap
2. Wipe up gasoline that may have spilled to prevent a fire
hazard.

15
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
•Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
•Do not fill the fuel tank completely full. Add
gasoline 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 gasoline to
expand.
•Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
•Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
•Always place gasoline containers on the ground
away from your vehicle before filling.
•Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
•When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
•If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
•If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
Checking the Gear Case Fluid
Level
The machines reservoir is filled at the factory with
approximately 4–5 quarts of high quality hydraulic fluid.
Check the level of the hydraulic fluid, on the sight
gauge, before the engine is first started and daily
thereafter. The recommended replacement fluid is:
Mobil DTE 26
Alternate fluids: If this 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.
Antiwear Hydraulic Fluid, ISO VG 68
Material Properties:
Viscosity, ASTM D445 cSt @ 40_C 65 to 71
cSt @ 100_C 8.4 to 8.9
Viscosity Index ASTM D2270 97 to 107
Pour Point, ASTM D97 –18_F to –30_F
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.
1. Position the machine on a level surface.
2. Release the hood latches and raise the hood.
3. Check the level of hydraulic oil on the sight gauge
(Fig. 5). The fluid level should be up to the middle of
the gauge window.

4. If the fluid level is low, remove the filler cap and add
enough hydraulic oil to bring the oil up to the proper
level.
5. Lower the hood and secure the latches.
Important The oil and filter must be changed
immediately when any contamination, sludge, water or
condensation appears in oil or on sight gauge. Determine
and correct oil contamination problem before restarting
engine and operating machine.

16
Checking the Pump Case Fluid
Level
The pump crank case is filled at the factory with
approximately 40 ounces of Mobil DTE Extra Heavy oil.
Check the oil level on the dipstick before the engine is first
started and daily thereafter. Change the oil initially after
25 hours of operation, thereafter change every 200 hours
of operation. See the chart below for equivalent oils.
Shell Morlina Sd 150
Chevron AW Machine Oil 150
Conoco Multipurpose R&O
0.1 150
Exxon Terresstic 150
Philllips Magnus Oil 150
Sun Sunvis 150

Castrol Paradene 150 R&O
Important The oil must be changed immediately when
any contamination, sludge, water, or condensation appears
in the oil. Determine and correct any oil contamination
problem before restarting the engine and operating the
machine.
1. Position the machine on a level surface.
2. Release the hood latches and raise the hood.
3. Remove the dipstick/filler cap and check the oil level on
the dipstick. The fluid level should be up to the FULL
mark (Fig. 6).

4. If the fluid level is low, add enough Mobil DTE Extra
Heavy oil or equivalent oil to bring the oil up to the
proper level. Do not overfill.
5. Lower the hood and secure the latches.
Checking the Tire Pressure
The tires are over inflated for shipping. Make sure that the
front and rear tires are inflated to 8 to 12 p.s.i. (55 to
83 kPa).
Checking the Accumulator
Charge
Have the accumulator charge checked before and after each
operating season by an Authorized Toro Distributor.
Charge accumulators contain high pressure
nitrogen. Nitrogen is the only gas to use for
accumulator charging. Installing improper gases in
an accumulator can cause an explosion and death.
Charging requires special tools and precautions.
•Charge the accumulator in a well ventilated
area.
•Have the accumulator checked and charged by
an Authorized Toro Distributor.
•Wear eye protection.
•Keep your hands and face away from the gas
valve.
Warning
Failure to open the bleed valve before servicing
high pressure water components can cause
personal injury, dismemberment, or death.
Slowly open the high pressure water bleed valve
before servicing any component connected to the
high pressure water system. Opening the high
pressure bleed valve allows any trapped water to
escape from the system and also allows the
accumulator piston to move to the bottom of the
accumulator cylinder.

Choke
To start the engine, close the carburetor choke by pulling
the choke control (Fig. 7) outward to the FULL position.
After the engine starts, regulate the choke to keep the
engine running smoothly. As soon as possible, open the
choke by pushing it inward to the OFF position.
Throttle
The throttle (Fig. 7) is used to regulate the engine speed.
Moving the throttle forward increases the engine speed
(FAST); rearward decreases the engine speed (SLOW).
Spray Wash Control
Pull the handle (Fig. 7) upward to activate the roller spray
wash system. Move the control knob up or down to adjust
the spray rate to keep the rollers free of debris.
Hour Meter
The hour meter (Fig. 7) registers accumulated hours of
engine operation. Use the hour meter to determine intervals
for service maintenance and lubrication.
Water Pressure Gauge
The water pressure gauge (Fig. 7) registers supply water
pressure in the system. It also acts as an interlock switch,
preventing the water pump from starting if the water
pressure is below 20–28 p.s.i., or stopping the water pump
if the water pressure drops below 7–13 p.s.i. Check the
gauge frequently to monitor the water pressure.
Circuit Breaker Reset Button
Push the button (Fig. 7) to reset the breaker after correcting
a malfunction in the electrical system. The button also
serves as a switch to interrupt power to the relays.
Spacing Control Lever
Moving the control (Fig. 7) away from the handle increases
the aerating ground speed and the distance between holes.
Moving the control toward the handle decreases the
aerating ground speed and the distance between holes. The
setting will be overridden when the machine is shifted to
the transport position.
Accumulator Pressure Lights
The high or low pressure lights (Fig. 7) will only illuminate
if a high or low pressure condition occurs in the
accumulator. If a light illuminates the system willl not
operate or shut down.
Traction Bail
The traction bail (Fig. 8) engages and regulates fore and aft
traction operation of the machine. Releasing the bail stops
traction operation and will also stop water injection in 3 to
4 seconds, unless the bail is re–engaged. The transport
speed is regulated by the amount the bail is moved.

Transport/Aerate Rocker Switch
The switch (Fig. 8) lowers machine onto the rollers to
commence aeration. The switch will override the spacing
control setting when it is moved to the transport position.
Aeration Engagement Button
Depressing the button (Fig. 8), starts the water injection
system only when the water pressure is above 28 p.s.i. and
the rollers are on the ground.
Aeration Stop Button
The red button (Fig. 8) stops the water injection system.
The system continues for a few seconds after the button is
pressed.
Parking Brake
Push the lever (Fig. 8) toward the machine to engage the
parking brake. A warning buzzer will sound if you attempt
to move the machine with parking brake engaged.
Fuel Shut-Off Valve
The fuel shut-off valve is located under the fuel tank. Close
the valve when storing or transporting (trailering) the
machine.
Operating Precautions
Follow these precautions when operating the aerator:
•Before aerating, inspect the work area for debris and
determine the best direction and pattern to operate the
machine.
•If the machine starts to vibrate abnormally, shut the
engine off. Remove the wires from the spark plugs to
prevent the possibility of accidental starting. Check the
machine for damaged parts. Repair any damage before
restarting the engine and operating the machine.
•Only use the aerator in daylight or when there is good
artificial light. Watch for holes or other hidden hazards.
Do not transport the machine close to a sand trap, ditch,
creek, or other hazard.
•To prevent roller marks, always raise the machine to the
transport position when parked on a green.
•Do not operate the water injection system on concrete
or asphalt because water jets will permanently damage
these surfaces. Do not run over the hose as damage will
occur.
•Do not operate the aerator with the roller or injection
system over the edge of anything that could be hit,
damaged, or injured by high velocity water blasts.
•Water jets from the injection system should not damage
irrigation heads on one pass of the machine. Do not
allow multiple shots from the injection system to hit
irrigation heads as damage will occur.
•Use a good, clean, quality water supply in the system. If
good quality water is not available, additional filtration
equipment may be required. Do not use chemicals in
the water system.
•Do not allow the machine to be subject to freezing
temperatures without draining, as damage to the system
will occur.
Starting and Stopping the
Engine
1. Make sure that the wires are installed on the spark plugs
and the fuel shut-off valve is open.
2. Make sure that the parking brake is engaged.
3. Pull the choke lever out to the FULL position and move
the throttle lever to the half throttle position.
Note: When starting a warm engine, the choke may not be
necessary, but HALF throttle is.

19
4. Insert the key into the ignition switch and rotate it
clockwise to start the engine. Release the key when the
engine starts. Gradually return the choke lever to the
OFF position (lever all the way in) after the engine
starts and warms up.
Important To prevent overheating of the starter motor,
do not engage the starter longer than 30 seconds. After 30
seconds of continuous cranking, wait 2 minutes before
engaging the starter motor again.
Important The engine is equipped with an oil pressure
interlock switch which interrupts the engine operation if
there is not sufficient oil pressure in the engine during
starting or operation. The engine may start but will not
continue to run due to a lack of oil pressure.
5. To stop the engine, move the throttle control downward
to the SLOW position and turn the ignition key to OFF.
Remove the ignition key.
Training Period
Before aerating with the machine, it is suggested that you
find a clear area and practice starting and stopping, raising
and lowering machine, turning, etc. This training period
will be beneficial to the operator in gaining confidence in
the performance of the aerator.
Water Supply
Recommended source with 7–8 gallons per minute. A
minimum pressure of 30 p.s.i. at the machine is required for
the pump to engage. Maximum allowable pressure of 200
psi. Although irrigation water pumped from ponds or
effluent holding pools can be used, not all conditions can be
handled by the filtration system. Additional or alternative
filtration may be required.
Operating Procedure
1. Make sure that the wires are installed on the spark plugs
and the fuel shut-off valve is open.
2. Uncoil a garden hose, making sure that there are no
kinks or bends in the hose. Lay out the hose so that
there are no obstructions between the machine and the
area to be aerated. Turn on the water supply to purge
any air from the hose. Turn off the water.
3. Connect the hose adapter (Fig. 9) to the garden hose,
then connect the adapter to the quick coupler on the side
of the machine.
2

Figure 9
1. Hose adapter 2. Quick coupler
4. Turn on the water supply and check the water pressure.
The water pressure must be at least 30 p.s.i.. If the
system pressure is not 30 p.s.i., make sure that the hose
is not kinked or obstructed, the water supply is turned
on, and the water filter is not plugged.
Do not operate the engine while bleeding the filter
head.
Caution
5. Reach under the fuel tank and press the bleed button on
top of the water filter head (Fig. 10). Hold the bleed
button down until all air is purged from the filter and
water comes out of the opening.

8. Start the engine; refer to Starting and Stopping the
Engine, page 18. Move the throttle to the FAST position
and disengage the parking brake.
9. Engage the traction bail and approach the area to be
aerated. Make sure that there are no obstructions
between the aerator and water supply.
10. Engage and hold the transport/aerate toggle switch to
fully lower the machine onto the rollers. Release the
switch when the machine is fully lowered; then press
the engagement button to start water injection.
Note: The injection operation starts approximately 4–5
seconds after the pump engages. Also, the injection system
will automatically stop if the traction bail is not engaged
within 3–4 seconds after starting the water system.
11. When aerating, work moving perpendicular from the
water supply to avoid running over the garden hose.
Use the front edge of the hood or rear corner of the
frame to align rows, if desired. When at the end of a
row, make an “S” maneuver and reverse the direction of
the aerator. Do not make sharp turns on a green or
scuffing from the tire may occur.
12. Regulate the roller spray wash, if required, to remove
debris from the rollers.
Note: A small amount of water from the regulator bypass
may come out of the spray wash nozzles even with the
spray wash in the “OFF” position.
13. In areas where greater hole depth or more frequent
holes are desired, the engage button can be held down
to allow multiple shots while machine is stopped.
Important Hole depths can reach 20 inches or more
when making multiple shots, so be aware of what is buried
below the turf. Also, an excessive amount of holes and
muddy turf conditions may occur when making multiple
shots.
14. To stop water injection, press the red button. The
system continues for a few seconds after the button is
pressed. Raise the machine to the transport position,
disconnect the supply hose, and move to the next
location.
Checking the Interlock System
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly,
causing personal injury.
•Do not tamper with the interlock switches.
•Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Caution
The purpose of the safety interlock system is to prevent the
engine from cranking or starting unless the traction bail is
in NEUTRAL and prevents the water system from
engaging if the machine is in the transport (raised) position.
It also stops aeration if the traction bail is released while
operating or if the machine is raised to the transport
position.
