6.6 SET–UP INSTRUCTIONS FOR
TURF UTILITY TRACTOR
1. Install and secure a 2” (51 mm) tow hitch ball to the
standard tractor drawbar. BE SURE the hitch ball is
a class 2 (3500 lb. capacity) or better ball.
CAUTION
!
Use ONLY the standard drawbar approved by
the tractor manufacturer. The height from the
ground to the top of the drawbar must be 13 to
19.7 inches (330–500 mm).
2. Mount power cable assembly (Part No. 889171) in a
suitable location at the rear of the tractor. Connect
the red cable end to the same post the tractor posi-
tive battery cable is attached to. Connect the black
cable to a good ground on the tractor frame. Refer to
wiring diagram.
NOTE: Cable lengths and eyelets may need to be modi-
fied depending upon the configuration of your trac-
tor.
3. Mount the GA–60 control panel at a location within
arms reach of the tractor operator. Connect the con-
trol box harness (Part No. 889174) to the GA–60
main harness (Part No. 889547). A wire harness
extension (Part No. 892790) may be used if addi-
tional wire harness length is required. This extension
is included in the long extension accessory (Part No.
892964).
4. The wheel brakes on the GA–60 are NOT USED
when towed with a turf utility type tractor. The brake
bypass jumper (Part No. 892793) must be plugged
into the wire assembly (Part No. 889052) on the
GA–60 control panel. See Figure 7. If the brake
bypass jumper is not installed, the GA–60 engine will
not start. Refer to wiring diagram.

Figure 7
1. Brake Bypass
2. Control Panel
NOTE: The GA–60 brakes are not utilized therefore the
towing tractor must weigh a minimum 2700 lbs.
(1225 Kg). The tractor brakes must be capable of
controlling the tractor and the 2300 lb. (1044 Kg)
GA–60.
5. Determine what type and size hydraulic quick cou-
plers are used on the towing tractor. Change the
ends on the GA–60 hydraulic hoses to match the
towing tractor hydraulic fittings. Add to hydraulic
hose length if required.
6. Attach long tongue extension to 2” (51 mm) hitch
ball on tractor draw bar. Route the wire harness,
power cable and hydraulic hoses through the hose
support mounted on the long tongue extension.
7. Connect wire harness, power cable and hydraulic
hoses to tractor. Remove GA–60 from pallet as
described in the following section.
8. With the GA–60 engine turned off and the heads in
the “UP” position, pull and turn the tractor fully to the
left and right. Make sure all hoses, wiring and hitch
move freely and are not rubbing against adjacent
parts.
9. With the GA–60 heads in the “UP” position, disen-
gage the uplatch bar shown in Figure 8. Start the
GA–60, move to a turf area and lower the aerator
heads. Lowering the aerator heads will increase the
GA–60 engine speed and will engage the aerator

drive as it lowers. The aerator drive will disengage
and engine will return to idle when the aerator heads
are raised.
NOTE: If raising the hydraulic lever lowers the aerator,
the hydraulic lines are reversed. Reverse the
hydraulic lines at the quick couplers.
10. The GA–60 can produce a maximum hole spacing of
5” (125 mm). Hole spacings larger than 5” (125 mm)
will SEVERELY DAMAGE the aerator mechanism.
NOTE: The tractor speed MUST BE kept below 2 mph
(3.2 km/hr) when aerating. BE SURE to use an
engine speed and transmission gear that will result
in a hole spacing of less than 5” (127 mm). Aerating
speeds exceeding the allowable 2 mph (3.2 km/hr)
will SEVERELY DAMAGE the aerator mechanism
components.

During transport with the aerator heads raised, the GA 60
can be transported at any reasonable safe speed
(10mph maximum) ALWAYS use extreme care when
towing aerator at any speeds above 5 mph.
NOTE: The GA 60 may be damaged if towed on a
flatbed trailer without the aerator heads lowered.
Place boards or similar type material on the trailer to
prevent damage to trailer and/or tines when the
heads are lowered.
6.7 REMOVING FROM PALLET
1. Carefully cut and remove all banding securing aera-
tor to shipping pallet.
2. Back the towing vehicle up to the GA–60. Position
the towing vehicle so the tongue may be lowered
onto the 5th wheel ball.
3. Loosen mounting clamp knob on rear of control
panel to allow the control panel to be mounted on the
right side hand hold of the Turf–Truckster or towing
vehicle. Tighten mounting clamp knob to secure.
4. Connect control panel cable from GA–60 to right side
of control panel. Attach multi–pin connector from the
bottom of the control panel to the connector
mounted on the right stopwall support.
5. Lock the hydraulic lift control on the Turf–Truckster
or towing vehicle in the float position to relieve
hydraulic pressure. This will allow the hydraulic
hoses to be connected more easily.
NOTE: After connecting the hydraulic hoses, BE SURE
to release the hydraulic lift control from the float
position.
6. Connect the quick coupler power cable from the
GA–60 to the Turf–Truckster or towing vehicle.
7. Start the Turf–Truckster or towing vehicle engine and
raise the aerator heads slowly to lower the tongue
onto the fifth wheel ball. Tighten ball grip to fifth wheel
ball by turning square nut on hitch coupler clockwise
until tight.
8. Raise aerator heads as high as possible to allow
GA–60 to be removed from pallet.
NOTE: Place various thickness boards or blocks in front
of pallet to help prevent the GA–60 from dropping to
the ground from pallet during removal.
BE SURE aerator heads are raised to their maxi-
mum height to assure the turf guards do not catch
on pallet.
WARNING
!
DO NOT allow anyone to stand directly behind
pallet during removal of the GA–60.

7.6 AERATING DEPTH ADJUSTMENT
The GA–60 is designed to aerate at a MAXIMUM depth
of 4” (102 mm). The operator should be aware that, in
extremely hard soil, the machine may not be capable of
pushing the tines 4” (102 mm) into the ground. DO NOT
operate with the depth setting at the 4” (102 mm) maxi-
mum when the tines are only penetrating 2–3 inches
(51–76 mm). Operating under these conditions will
cause premature wear and/or broken components in the
aerator linkage. If the aerator tires consistently ride up off
the turf or bounce up off the turf, the ground is too hard.
NEVER try to aerate at a depth greater than the soil
conditions will allow. The operator must first make a test
run, measure the depth of the holes, and set the depth
adjustment to correspond. After aerating the area once
or twice at that depth to loosen the sub–soil, it may be
possible to lower the settings each time until the 4” (102
mm) maximum depth can be accomplished without
abusing the GA–60.
AGAIN––Aerate a small test plot, measure the depth of
the hole and adjust the depth setting on the GA–60 to
match it.
If aerating extremely hard soil, additional penetration is
possible with added water, either by rain or irrigation.
Moist ground is easier to aerate than dry ground and is
also easier on the aerator mechanism.
If aerating in soil with rocks or stones, additional penetra-
tion over time may not be possible. The operator must
determine what depth is possible for that area and be
sure he does not exceed that depth.
Adjusting the depth from 2 1/2” (64 mm) to 4” (102 mm) is
accomplished by adjusting the 1/2” (13 mm) axle stop
spacers shown in Figure 11.
