ADJUSTMENTS 4
11
lbs. (54 - 68 N-m). Check operation of the steering
for free operation. A slight amount of roughness is
permitted after the front wheel has turned either
direction 15°. It is better to have the allowable
roughness than the maximum permitted backlash. If it is necessary to readjust the idler shaft, the
locating washers (Part No. 816449) must be rotated
to prevent the serrations from falling into the same
marks.
4.6 SPACING CONTROL ADJUSTMENT __________________________________________
Note: Hole spacing on the GA-30 is controlled by the
forward speed of the unit. The faster the unit travels, the
more space between the holes.
1. Make a test run with the spacing control knob set at 2
1/2” (64 mm), and direction control pedal fully
depressed.
2. Measure the distance (center to center) between the
holes. If the distance is more or less than 2 1/2” (64
mm) adjust as follows:
Set the spacing control lever at the 2 1/2” (64 mm)
mark.
3. Jack rear wheels off the ground. Support unit with
jack stands.
4. Remove bolt from chain drive sprocket.
5. Lift seat and remove internal rubber cover.
6. Remove side panel and muffler cover, remove drive
belt.
7. With the aerator head fully lowered, and the throttle
at full speed (3600 ± 75 R.P.M.), place a slow
speed tachometer against the threaded center of
the hydraulic motor.
8. Adjust the spacing control rod (Part No. 524160)
until the hydraulic motor speed stabilizes at 28 ± 1
R.P.M. Use the adjusting screw (Part No. 524453)
to set position by screwing forward to decrease hole
spacing (lengthening rod). Screw backward (shorten
rod) to increase hole spacing. Lock the two (2) nuts
(Part No. 306320) and override spring (Part No.
524083) into position so that the spring may
compress 1/8” (3.2 mm) after adjustment is
complete. Refer to Figure 4A.
9. Replace drive belt and panels.
10. Replace internal rubber cover and chain drive
sprocket bolt.

4.7 REVERSING GEARBOX PROPER GEAR BACKLASH ____________________________
Note: The gear lash can be inspected while the reversing
gearbox is still on the unit. The gear backlash should be
zero.
1. Locate 2 tine rams connected through linkage to the
same reversing gearbox. Grasp both of the tine rams
low near the tine holder mounting. Push one of the
tine rams in until it stops and hold it there. Slowly
move the other tine ram in and out, look for
independent movement of the tine ram and listen for
a knocking noise coming from the gears in the
reversing gearbox.
2. A correctly adjusted reversing gearbox should feel
solid and the tine rams should not move indepen-
dently from one another. There should not be any
knocking noises coming from the gears in the
reversing gearbox. If the tine ram does move
independently from the other tine ram, the linkage
from the tine ram to the reversing gearbox should
be inspected for damage or wear. If no wear or
damage is found in the linkage, then the reversing
gearbox should be adjusted for zero gear backlash.
