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
Before Operating
• Owners of this Aerator must give operators and
employees full operation and safety instructions before
allowing them to operate this machine and at least
annually thereafter. An operator who has not read and
fully understood all operating and safety instructions is
not qualified to operate this machine. Become
familiar with all controls and know how to stop
quickly.
• Do not allow children to operate the machine. Do not
allow adults to operate the machine without proper
instruction.
• Remove all debris or other objects that might interfere
with operation. Keep all bystanders away from the
work area.
• Locate and mark all under ground obstructions such as
irrigation components, electrical or telephone lines.
• Make sure tractor is in neutral and hand brake applied
before starting. Refer to Tractor Operator’s Manual for
safe starting procedures.
• Using the machine demands attention, and to prevent
loss of control:
– Use only in daylight or when there is good
artificial light.
– Watch for holes or other hidden hazards.
– Do not transport machine close to a sand trap,
ditch, creek or other hazard.
– Reduce speed on side hills and before making
sharp turns to prevent tipping or loss of control.
– Look behind the aerator before backing up.
• If the tines strike a solid object or the machine vibrates
abnormally, shut the engine off. Remove key from
ignition switch. Check aerator and traction unit for
damage. Repair any damage before restarting the
engine and operating the tines. Be sure tines are in
good condition and all bolts are tight.
• Before leaving machine unattended, disengage power
to aerator, lower aerator and set parking brake. Stop
engine.
• Never dismount while tractor is in motion. Never get
on or off tractor while engine is running and PTO drive
shaft is engaged. Never step over PTO shaft to reach
other side of aerator – walk around the machine.
• Park aerator on a hard, level surface, install rear
support/safety stand and chock roller before
disconnecting from tractor.
• If it is necessary to probe below the soil surface, use a
non conductive material to prevent electrical shock in
case electrical wires are present.
• To maintain full steering control, add front end
weights to tractor. Refer to Tractor Operator’s Manual
for weight requirements.
• Keep all shields and safety devices in place. If a
shield, safety device or decal is damaged, repair or
replace it before operation is commenced. Also tighten
any loose nuts, bolts and screws to ensure machine is
in safe operating condition.
Transporting
• Be sure you are in compliance with all regulations
regarding transporting equipment on the public roads
and highways.
• Ensure that all reflectors and lights required are in
place and are clean and visible by overtaking and
oncoming traffic.
• Never allow anyone to ride on the machine during
transport.

Page 4
• Reduce speed on rough roads and surfaces.
• Independent brakes should always be locked together
when on the road.
PTO Shaft
• For all PTO shaft steel parts (tubes, bearings, joints
etc). disassembly or repairs, it is highly advisable to
contact your local Toro distributor. Removal of
components for repairs and re–assembly may damage
some parts if not carried out correctly using special
tools available in a dealer’s workshop.
• The PTO shaft should not be used without the guards
supplied, with partial protection, with damaged guard
or without the special anti–rotation chains correctly
hooked, so as to permit the maximum angle of the
PTO shaft without breaking the chains.
Maintenance
• Beforemaking adjustments or performing maintenance
on the aerator, switch off the engine, stop the PTO and
apply the hand brake before dismounting from the
tractor. Be sure the aerator is on the ground or lowered
onto the rear castor/safety stand.
• Support the machine with the rear castor/safety stand
when working beneath it. Never rely on the tractor’s
hydraulics to support the machine.
• Place all controls in neutral, stop the engine, apply
hand brake and wait for all moving parts to stop before
servicing maintaining, adjusting or unblocking the
aerator.
• Be sure machine is in safe operating condition by
keeping nuts, bolts and screws tight. Check the tine
mounting bolts and nuts frequently to be sure they are
tightened to specification.
Storage Safety
• Store the aerator on a firm level surface.
• Store aerator away from areas of human activity.
• Do not allow children to play on or around the stored
machine.
• Make sure the aerator is sitting, or blocked up firm and
solid and will not sink into soft ground causing it to
tip.
• Ensure that the rear stand pin issecured in place.
• Block the aerator to prevent it from rolling or tipping.
• Do not check or adjust belt tension when the tractor
engine is running.
• Be sure all guards are replaced and the hood is secured
shut after maintaining or adjusting the machine.
• Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or
assistance is desired, contact an Authorized Toro
Distributor. To ensure optimum performance and
safety, always purchase genuine Toro replacement
parts and accessories to keep the Toro all Toro. Never
use “will-fit” replacement parts and accessories made
by other manufacturers. Look for the Toro logo to
ensure genuineness. Using unapproved replacement
parts and accessories could void the warranty of The
Toro Company.

Adjust PTO Shaft Length
Important A long PTO shaft is supplied with machine
to accommodate large variations in the tractor’s PTO and
3 point locations. For most tractors this shaft is too long
and must be cut to correct length or gearbox damage may
result.
1. With the aerator vertical or angled slightly forward,
lower the aerator until the gear box shaft is
approximately the same height as the tractor PTO
shaft. This is the shortest distance between the two
shafts.
2. Measure the distance from the lock groove of the
tractor PTO shaft to the lock groove of the aerator
gearbox PTO shaft. Record this dimension.
3. Fully collapse PTO shaft and measure the distance
between the lock pin collars. Record this dimension.
4. At it’s shortest length, the two halves of the PTO shaft
must have at least 1.5 inches (37 mm) of additional
clearance to collapse (Fig. 6). If the dimension in step
2 is not at least 1.5 inches (37 mm) greater than the
10
Page 11
dimension in step 3, the PTO shaft is too long, proceed
to step 5. If there is enough clearance to allow PTO
shaft to collapse, proceed to step 10.

shorter the shaft must be, when connected, to ensure a
clearance of 1.5 inches (37 mm).
A. Subtract the dimension recorded in step 3 from the
dimension recorded in step 2. Record this
dimension.
B. Subtract the result in step 5A from 1.5” (37mm).
The PTO shaft must be shortened by this amount.
6. Using a hacksaw, cut the yellow guards and the steel
tubes shorter by the calculated length. Cut both halves
of the PTO shaft
7. Deburr ends of steel tubes internally and externally.
8. Remove all debris from tube sections.
9. Grease steel tubes liberally.
10. Assemble PTO shaft and secure to aerator and tractor.
11. Measure the shaft. If not at least 1.5 inches (37 mm),
repeat procedure.
12. Raise aerator to highest position. There must be at
least 3 inches (75 mm) of overlap of the halves. Adjust
3 point lift stop, if necessary. Refer to Adjust 3 Point
Lift Stop, page 11.

Depth Guides
Depth guides (1 thru 27) are provided to give equal
increments for adjustment. The numbers do not relate to
measurements of depth as this changes with tine type and
amount of tine wear. Adjustment between two numbers
will give approximately .20 inches (5 mm) change in
depth. The higher the number, the deeper the tine
penetration. Always adjust each side to the same number
(Fig. 18).

Operation
Adjust Tine Depth
To adjust the working depth of the tine, proceed as
follows:
1. Remove the lynch pin from each depth adjust handle
(Fig. 19).

Figure 20
1. Depth guide
Important If a large change in height is required,
adjust each leg by a small amount to ensure the roller legs
are adjusted as evenly as possible.
Note: Remember when depth changes are made, you will
need to adjust the top link length to give the correct
machine angle. Refer to Connect Upper Link, page 8.
Important Tine depth is affected by the mounted
angle of the aerator as well as the depth setting. If the
aerator is angled rearward, the tine heads may contact the
turf guards and damage may occur. Depths 26 & 27
cannot be used when the aerator is in the vertical position.
See Depth Chart.
2. Turn the depth adjuster handles to raise (deeper) or
lower (shallow) the roller.
Note: Make sure that the roller is on the ground once the
depth is chosen.
3. Depth guides (Fig. 20) are provided with numbers 1
through 27. Depth varies with the mounted angle of
aerator, tine type and amount of tine wear. Refer to
Depth Chart on page 16. Adjustment between two
numbers will give approximately 0.20 inches (5 mm)
change in depth. The higher the number, the deeper the
tine penetration. Always adjust each side to the same
number.
4. Install the depth adjust handle lynch pins before
running the machine, even if you are just testing for
correct depth.
Important Tine depth is determined by the tine type,
depth adjustment, amount of tine wear and mounted angle
of the aerator. Refer to Depth Chart on page 18.
Important Maximum depth is achieved when the
aerator is mounted vertically (Fig. 21) and the depth
adjustment set at 25. In this condition, do not operate at
greater depth settings, as there is minimal clearance
between the tine head and the turf guards. Never operate
with the aerator angled rearward or damage to the turf
guards may occur.

In some instances, angling the aerator forward may
improve hole quality but will also reduce aeration depth
and gain clearance with the turf guards. A forward angle
of approximately 4_ is a good initial setting. Use a
magnetic based angle indicator to determine the forward
angle, or use the following procedure:
A. Position aerator on a flat level surface.
B. Make sure aerator roller is on the ground and depth
indicator is set at desired setting (Fig. 22).

Note: In instances where sufficient root growth exists, the turf guards may be removed to attain maximum depth without
damaging the turf guards.
Note: For future reference, record the upper link length
that achieves the desired operating angle.
• Gear Selection
Note: Refer to tractor operator’s manual for operating
instructions.
Tractor Controls
It is necessary to familiarize yourself with the operation of
the following tractor controls before you are able to
operate the aerator:
• PTO Engagement
• 3-Point Hitch (Raise/Lower)
• Clutch
• Throttle
Principles of Operation
The tractor’s three point hitch linkage lifts the aerator for
transport and lowers it for operation.
The tractor’s power take-off (PTO) power is transmitted
via shafts, gearbox and drive belts to a number of
crankshafts which drive the tine holding arms into the turf
surface.
21
Page 22
As the tractor travels forward with the PTO engaged and
the machine lowered, a series of holes are created in the
turf surface.
The depth of the tine’s penetration is determined by the
mounted angle of the aerator and the height of the depth
control roller.
The distance between the holes created is determined by
the tractor’s gear ratio (or hydrostatic traction pedal
position) and the number of tines in each tine head.
Simply changing engine rpm does not change hole
spacing.
Training Period
Before using the aerator, find a clear area and practice
using the machine. Operate the tractor at recommended
gear settings and PTO drive speeds and become
thoroughly familiar with machine handling. Practice
stopping and starting, raising and lowering the aerator,
disengaging the PTO drive and aligning the machine with
previous passes. A practice session assures confidence in
the performance of the Aerator and helps ensure use of
proper operating techniques wherever the machine is
operated.
If there are sprinkler heads, electrical or communication
lines or other obstructions in the area to be aerated, mark
these items to ensure they are not damaged during
operation.
Caution
To avoid personal injury, never leave the tractor
seat without first setting the parking brake and
disengaging the PTO drive. Never perform
aerator repairs without first lowering the aerator
onto the castor/safety stand. Be sure all safety
devices are secured in proper place before
resuming operation.
Before Aerating
Inspect the area of operation for hazards that could
damage the machine and remove them, if possible, or plan
how to avoid them. Carry replacement tines and tools to
effect repairs should tines contact foreign materials.
2. At a low tractor engine rpm, engage the power take off
(PTO) clutch to start the aerator working.
Important Do not operate aerator at 540 PTO rpm
when lifted out of the ground. This machine can be
damaged if operated at full speed without the tines
working in the turf. Never operate aerator without tine
heads installed
3. Select a gear that gives a forward speed of
approximately .6 – 2.5 MPH (I to 4 km/hr) at (refer to
tractor operator’s manual) rated PTO speed.
4. As the clutch is released and the tractor moves
forward, lower the machine fully into work and
increase engine speed to give a maximum of 540 rpm
at the PTO.
Important Never operate the tractor PTO in excess of
540 rpm or damage to the aerator could occur.
Note: Make sure that the roller is on the ground.
5. Note the hole pattern. If you require greater hole
spacing increase forward speed of the tractor by
changing up a gear or with a hydro–static drive tractor,
shift the hydrostat lever or pedal to give faster speed.
For closer hole spacing, decrease tractor forward
speed. Changing engine speed, in a particular gear,will not change the hole pattern. Operate at an
engine speed that the aerator runs smoothly.
Important Look behind frequently to ensure the
machine is operating properly and alignment is
maintained with previous passes.
6. Use the front tractor wheel as a guide to maintain
equal lateral hole spacing with the previous pass.
7. At the end of the aeration pass, raise the aerator, lower
the engine rpm and disengage the PTO.
8. If you back into a tight area (like a tee box), disengage
the PTO and raise the aerator to it’s highest position.
Use caution not to catch the turf guards on the turf.
9. Always clear the area of all damaged machine parts,
such as broken tines, etc., to prevent their being picked
up by mowers or other turf maintenance equipment.
10. Replace broken tines, inspect and correct damage to
those still useable. Repair any other machine damage
before commencing operation.
Transport Operation
Aerating Procedures
Note: When using needle tine heads, make sure to read
instructions, included with kit, for unique operating
procedure.
1. Lower the aerator on the 3–point linkage so that the
tines are nearly to the ground at the lowest part of their
stroke.
To begin transport operation, raise the aerator and
disengage the PTO. To avoid loss of control, traverse
steep inclines slowly, approach rough areas at reduced
speed and cross severe undulations carefully.
Important Do not exceed transport speeds of 15 mph
(24 km/hr).
22
Page 23
Caution
Do not exceed the maximum or minimum tractor
tire inflation pressures as recommended by tire
manufacturer.
Inspection and Cleanup after
Use
After daily use, thoroughly wash the machine with a
garden hose without a nozzle so contamination and seal
and bearing damage due to excessive water pressure will
be avoided. A brush may be used to remove caked-on
material. Use mild detergent to clean the covers. Applying
a coat of auto wax periodically will retain the cover’s
glossy finish. After cleaning, inspect for machine
damage, gear oil leakage, component and tine wear.
7. Always check/adjust top link whenever aeration depth
is changed. The front of the aerator should be vertical
or angled slightly forward. Experiment with depth and
angle to achieve best hole quality.
Note: Once optimum hole quality is attained, record depth
setting and the upper link length for future reference.
Caution
To avoid personal injury, never leave the tractor
seat without first setting the parking brake and
disengaging the PTO drive. Never perform
aerator adjustments or repairs without first
lowering the aerator onto the castor/safety stand.
Be sure all safety devices are secured in proper
place before resuming operation.
Optional Core Windrower
Operating Tips
1. Gradually engage PTO at low engine speed while
increasing throttle to 540 PTO rpm (maximum) while
lowering aerator. Operate at an engine rpm that the
aerator runs most smoothly.
Note: Changing engine / PTO rpm in a particular tractor
gear (or fixed hydrostatic pedal position on tractors with
hydrostatic transmission) will not change forward hole
spacing.
Important Do not operate PTO at high rpms for
extended time periods when aerator is out of the
ground.
2. Make very gradual turns when aerating. Never make
sharp turns with PTO drive engaged. Plan your
aeration path before lowering the aerator.
3. If tractor “bogs” down when operating on hard ground
or going uphill, raise aerator slightly until speed is
regained, then lower aerator again.
4. Do not aerate if ground is too hard or dry. Best results
are obtained after a rain or when turf has been watered
the previous day.
Note: If the roller rides up off the ground while aerating,
the ground is too hard to achieve the desired depth, reduce
the aeration depth until the roller contacts the ground
during operation.
ProCore 660 only
When using hollow tines, an Optional Core Windrower
(Toro Model No. 09732) is available to place cores in
narrow rows behind the machine.
Optional Contour Following Kit
An Optional Contour Following Kit (Toro Model No.
09154) is recommended for aeration on undulating or
uneven surfaces.
5. Raise aerator penetration, if ground is hard packed.
Clean–up cores and re–aerate at deeper penetration,
preferably after watering.
6. The aerator is offset to one side to allow aerating
without driving over the cores with the tractor tires.
Whenever possible, aerate with the longer offset
towards the previous aeration pass.

Maintenance
Lubrication
Greasing Bearings and Bushings
The main working bearings of the aerator are sealed for
life and require no maintenance or lubrication. This
drastically reduces the maintenance required and
eliminates the risk of grease or oil being dropped onto the
turf.
There are grease fittings that must be lubricated with an
SAE multi–purpose, high–temperature grease with high
pressure (EP) performance or SAE multi–purpose lithium
base grease.
The gearbox is filled with 85/140 gear oil or equivalent.
Check gearbox oil level every 6 months or 100 hours.
1. Remove check plug at rear of gearbox (Fig. 28).

At the end of an aerating season or when the aerator will
not be used for a long period, it is good practice to carry
out the following preventative maintenance.
1. Clean off any dirt or grease that may have
accumulated on the aerator or any of the moving parts.
2. Remove the tines and clean out hollow tines. Coat
tines with oil to prevent rusting during storage.
3. Open the hood and clean out the inside of the machine.
4. Lubricate all grease fittings.
5. Store the machine with the roller and castor wheel
standing on a hard, dry surface or board and block the
roller.
6. Remove PTO drive shaft and store under hood
7. Paint the roller and touch–up any other scratches on
the paintwork.
8. Replace any missing or damaged decals.
9. Store the aerator inside a dry secure building. Inside
storage will reduce maintenance, give a longer
working life and increase the residual value of the
machine. If inside storage is not available, cover with
a heavy sheet or tarpaulin and secure tightly.
Model 880
Left cover – Left & left center belts
Right cover – Right and Right center belts
11. Slide belts off driven and driver pulleys.
