SAFETY
TOWING SAFELY
TO HELP PREVENT BODILY INJURY DUE TO LOSS
OF STABILITY OR CONTROL:
• Stopping distance increases with speed and weight of
towed load. Travel slowly and allow extra time and distance
to stop.
• Do not exceed maximum towing capacity of towing vehicle
listed in the vehicle operator's manual.
• Total towed weight must not exceed limits specified in
towing vehicle operator's manual.
• Do not tow this machine behind a motor vehicle such as a
car, truck or ATV.
• Excessive towed load can cause loss of traction and loss
of control on slopes. Reduce towed weight when operating
on slopes.
• Towing this machine behind a ZTR (Zero Turning Radius)
mower is not recommended due to the sharp turning ability
of the ZTR. Damage to this machine or the ZTR may result.
ZTR’s typically operate at higher speeds. Operating above 5
mph may result in damage to this machine.
• Use only approved hitches. Tow only with a machine that
has a hitch designed for towing. Do not attach this machine
except at the approved hitch point.
SAFETY
• Follow the manufacturer's recommendations for weight
limits for towed equipment and towing on slopes. Use
counterweights or wheel weights as described in the towing
vehicle operator's manual.
Read the general safety operating precautions in your towing
vehicle operator's manual for additional safety information.
PROTECT BYSTANDERS
• Do not turn sharply. Use additional caution when turning or
operating under adverse surface conditions. Use care when
reversing. To avoid jack-knifing, do not allow towing vehicle
wheels to contact tow bar.
• Keep bystanders away when you operate this machine.
• Before you back look carefully behind for bystanders.
• Before you operate any feature of this machine, observe
your surroundings and look for bystanders.
• Do not shift to neutral and coast downhill.
KEEP RIDERS OFF TOWED ATTACHMENT
• Keep riders off towed attachment.
OPERATE SAFELY
• Use this machine for intended purpose only.
• Riders on a towed attachment are subject to injury, such as
being struck by objects and being thrown off the attachment
during sudden starts, stops and turns.
• This machine is intended for use in lawn care and home
applications.
• Do not tow behind a vehicle on a highway or in any high
speed applications. Do not tow at speeds higher than
maximum recommended towing speed.
• Riders obstruct the operator's view, resulting in the
attachment being used in an unsafe manner.
• Keep riders off of tow bar.
• Towing speed should always be slow enough to maintain
control. Travel slowly over rough ground.
KEEP BODY PARTS FROM UNDER TOW BAR
• Do not let children or an untrained person operate machine.
Before disconnecting this machine from towing vehicle hitch
plate:
• Do not let anyone, especially children, ride on this machine
or the towing vehicle.
• Stop on level ground.
• Stop towing vehicle engine.
• Check towing vehicle brake action before you operate.
Adjust or service brakes as necessary.
• Lock towing vehicle park brake.
• Block wheels of the machine.
• Make sure body parts are not under tow bar.
• Keep all parts in good condition and properly installed. Fix
damaged parts immediately. Replace worn or broken parts.
Replace all worn or damaged safety and instruction decals.
• Do not modify the machine or safety devices. Unauthorized
modifications to the towing vehicle or machine may impair its
function and safety, and void the warranty.
• Keep all nuts, bolts and screws tight.

Adjustment Bolts
To Tractor
NOTE: The adjustment is made with the
aerator attached to the rider or lawn/garden
tractor with the wheels in transport position.
OPERATION
WHEN TO AERATE
CAUTION
Your Aerator should not be used when lawn conditions
are too wet or too dry. To determine condition, dig a small
amount of your soil (about three inches deep):
After first thirty minutes of use check all fasteners for
tightness.
To avoid damage to spoons, always engage transport wheels
to raise the spoons when crossing concrete or asphalt walks,
drives, or roads.
If soil appears powdery and brittle- it is too dry. Wait until a
later date, the Tines will not penetrate properly.
If soil appears damp, roll a small amount into a ball in the
palm of your hand- if it forms a ball, then it is too wet. Ideally,
the soil should fall apart when rolled in the palm of your
hand. Wait until a later date for soil to dry. If soil is too wet,
the Tines will not operate effectively and your tractor could
loose traction, causing lawn damage.
Use the Aerator only on an established lawn, never on newly
laid sod.
To avoid possible personal injury and/ or equipment never
exceed the recommended operating speed range of 3 to 5
MPH.
Only tow Aerator behind vehicles for which it was designed,
riders and lawn/garden tractors.
MOUNTING AND TRANSPORTING
Attach aerator to your rider or lawn/garden tractor using Pin
and Hairpin Cotter Supplied.
Do not stand/ride on Aerator, bodily injury could result.
Always disconnect Aerator from tractor when cleaning or
servicing unit.
To Place in Transport Position:
•
Push REARWARD on Lift Handle (11) towards Transport
Lock Pin in Side Plate. Pull Handle OUT and mover over
Lock Pin. Aerator now rests on wheels.
Never exceed the Weight Tray capacity.
Do Not attempt to disconnect Aerator from tractor with weight
in Tray.
To Place in Operating Position:
When backing, carefully back straight to avoid Jack-knifing,
which could result in damage to equipment.
•
Pull OUT on Lift Handle (releasing from Transport
Lock Pin) and move FORWARD. Aerator now rests on
Plugging Spoons.

MAINTENANCE
Should rust develop, sand lightly and then paint area with
enamel.
USE OF ADDITIONAL WEIGHT
The weight required to give a recommended penetration
of approximately two to three inches will vary according
to soil type and conditions. Concrete blocks, patio blocks,
sand bags, or any other type of weight can be added to
Aerator Tray as required. Weight can be secured by using
tie downs through holes in Tray Flanges. Tie downs are not
furnished with your unit. Usually three Concrete Blocks will
be sufficient, but more or less weight may be required.
Periodically check all fasteners for tightness.
IMPORTANT:
Apply a drop of lubricating oil to each Nylon Bearing and the
Aerator Axle before each use.
To prevent rust on plugging spoons, apply a light coat of
oil on the working areas of spoons after each use. Should
rust appear on any other part of your Aerator, sand lightly to
remove rust and coat lightly with enamel.
•
•
•
Drive your tractor to location to be Aerated.
Lower Aerator to Operating Position.
Drive the Tractor FORWARD approximately ten feet and
stop.
•
•
Observe the operation- there should be a Plug hole
approximately every ten to twelve inches and not more
than three inches deep.
Plugging spoons are manufactured with special steels and
are heat treated to resist wear of abrasive soil. Striking
sub-surface objects can cause spoon breakage. Contact
our Customer Service Department to purchase replacement
Plugging Spoons (Part# B-4855-10). See “GETTING
QUALITY SERVICE”.
Add or remove weight to obtain this condition.
MAINTENANCE:
The key to years of trouble-free service is to keep your
Aerator clean and dry.
Periodically check the spoons remove any debris which
might build up and restrict their action.
Never allow wet material to remain in Tray for extended
periods of time.
After each use, service unit as described and store in a dry
area, shielding tines to avoid injury.
Occasionally check all moving parts for free movement and,
if necessary, lubricate with oil.
