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 some 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. If the dimension in
step 2 is not at least 1.5 inches (37 mm) greater than
the 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 9.

Depth guides (Fig. 17) - 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.

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. 18).
Figure 18

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. 19) are provided with numbers
1 thru 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 .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 19

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, page 17.
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 and mounted angle of the
aerator. Refer to Depth Chart on page 17.
Maximum depth is achieved when the aerator is
mounted vertically (Fig. 20) 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 20
90
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.
C. Measure and record the distance from the
ground to the lower rear corner of the frame (H1")
and front corner of the frame (H2") (Fig. 21).
D. Adjust upper link until the difference between
H1"-H2" matches desired forward angle of
aerator (See Angle Chart below).

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
Gear Selection
NOTE: Refer to tractor operator's manual for operating
instructions.
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.
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 assure they are not
damaged during operation.
CAUTION
To avoid personal injury, never leave the
tractor seat without first setting the park
ing brake and disengaging the PTO drive.
Never perform aerator repairs without first
lowering the aerator onto the castor/safe
ty stand. Be sure all safety devices are se
cured in proper place before resuming op
eration.
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.

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.
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 the turf 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
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).
CAUTION: Do not exceed the maximum or minimum
tractor tire inflation pressures as recommended by tire
manufacturer.
INSPECTION AND CLEAN-UP 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.
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.
5. Decrease 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.

20
OPERATION
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 park
ing brake and disengaging the PTO drive.
Never perform aerator adjustments or re
pairs 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
When using hollow tines, an Optional Core Windrower
(Toro Model No. 09731) is available to place cores in
narrow rows behind the machine.
OPTIONAL CONTOUR FOLLOWING KIT
(Not recommended for use on greens)
An Optional Contour Following Kit (Toro Model No.
09154) is recommended for aeration on undulating or
uneven surfaces.
