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.
•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.
•Do not operate machine while wearing sandals, tennis
shoes, sneakers or shorts. Also, do not wear loose
fitting clothing which could get caught in moving
parts. Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes, ear protection
and a helmet is advisable and may be required by
some local ordinances and insurance regulations.
While Operating
•Keep all bystanders and pets away from the work
area.
•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.
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.

•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.
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 is secured in place.
•Block the aerator to prevent it from rolling or tipping.
Maintenance
•Before making 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.
•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

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.
1.5”
(37 mm)

Figure 6
1. PTO shaft
5. Use the following calculation to establish how much
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.
Connect PTO Shaft
1. Connect PTO shaft to gearbox input shaft (Fig. 7).

3. Slide PTO shaft forward as far as it will go.
4. Depress pin to secure PTO shaft in place. Slide PTO
shaft back and forth to make sure it is properly locked.
5. Connect shield safety chains from powershaft sections
to welded clips on link arms or to PTO shields. Make
sure chains remain slack when aerator is raised or
lowered.
To help prevent bodily injury, keep all PTO
shields in place and connect shield chains to link
arms or PTO shields to prevent shields from
rotating during operation.

Figure 11
1. Sway link
1. Adjust the lower links inboard until they contact the
aerator mounting plates. This will reduce the stress on
the pins. If the tractor has sway chains instead of sway

13
links, it is recommended that washers be installed
between the lower link arm and lynch pin to reduce the
over hung load on the lift pins.
Note: Refer to tractor operator’s manual for additional
installation and adjustment procedures.
Level Aerator Side–to–side
1. Park tractor and aerator on a level, firm surface. Make
sure both depth gauges are set at the same setting.
2. Place level on top of aerator hood to check for level
side-to-side (Fig. 12).

3. Turn the adjustable link body (if provided) to raise or
lower the link arm until the aerator is leveled
side–to–side.
Note: Refer to tractor operator’s manual for additional
adjustment procedures.
Adjust 3-Point Lift Stop
Adjust and set 3 point lift stop (Fig. 13) to provide
approximately 4” ground clearance, when in the raised
position, to minimize PTO angle when raising aerator. For
transporting or trailer loading/unloading, the full lift range
can be used as long as the PTO tubes do not slide apart.
Operating the PTO in the fully raised position may
damage the PTO or other components.

a trailer, remove nuts securing each end of turf finger tool
bar to roller legs and pivot turf finger tool bar upward.
Adjust Roller Scraper
Adjust roller scraper so there is approximately a 1/8”
(3mm) gap between scraper and roller.
1. Loosen fasteners securing each end of scraper to roller
scraper tab (Fig. 14).
2. Slide the roller scraper up or down to required position
and tighten fasteners.

Adjust Turf Guards
Before starting your new aerator, remove the rear castor
stand and lower the machine on the 3–point linkage until
the depth control roller is resting on the ground. From the
rear of the machine, check that the tines line up exactly
with the center of the gaps in the turf guards. Install the
correct turf guards (Fig. 16), if necessary.
Figure 16
Note: Turf with a good root structure may not require the
turf guards. If this is the case. Do not remove the turf
guard tool bar as this adds support to the roller leg
assembly. Just remove the plastic fingers from the turf
guard bracket.
Removing Aerator from Tractor
1. Stop vehicle on a level surface, not on a slope.
2. Disengage the PTO and engage the parking brake.
3. Stop the engine and remove the key from ignition
switch.
4. Before leaving the operator’s seat on tractor, wait for
engine and all moving parts to stop.
5. Install rear castor/safety stand, collapse it to storage
position and install pin. Tighten knob.
Note: Aerator can be stored on original shipping pallet if
desired. Remove castor wheel.
6. Disconnect safety shield chains from PTO tractor.
Secure end of chain to aerator side of PTO shaft to
prevent PTO shaft from coming apart.
7. Slowly lower aerator until rear castor/safety stand
contacts ground.
8. Lower roller, by adjusting depth control handles, until
roller contacts ground.
9. Loosen locking nut and rotate adjusting link to release
tension between aerator and tractor.
10. Remove lynch pin and top link pin securing center link
to bracket.
11. Push release pin to disconnect powershaft from tractor
PTO shaft.
12. Slide powershaft back and remove from tractor.
13. Remove lynch pins and slide lower link arms off hitch
pins.

Controls
Depth Adjustment Handles
Remove lynch pins, rotate handles to raise or lower tines
to desired depth and replace lynch pins (Fig. 17).

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).
1
Figure 19
1. Depth adjustment handle
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.

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.
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.

Figure 21
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).
