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.

5082

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

SET UP 6

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.

The weight of the unit may cause the pallet to

slide back quickly when the GA–60 is removed.

9. Slowly drive the Turf–Truckster or towing vehicle for-

ward to remove GA–60 from pallet.

OPERATION 7

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.
