Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.

Caution signals a hazard that may cause minor or
moderate injury if you do not follow the recommended
precautions.

This manual uses two other words to highlight
information.
mechanical information and Note: emphasizes general
information worthy of special attention.

Important calls attention to special

• 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.

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.

3

• 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

• 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.

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.

• 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.
