Connecting the Traction
Unit Upper Link
Models SR54-S and SR70-S
Parts needed for this procedure:

3 Link pin
3 Lynch pin
Procedure
1. Mount the spring-loaded top link to the aerator
bracket with 2 link pins and lynch pins
2. Loosen the locknut on the traction unit upper
link. Adjust the upper link length until it aligns
with the clevis on the spring-loaded top link of
the aerator (Figure

3. Connect the traction unit upper link to the clevis
on the spring-loaded top link and secure with a
link pin and lynch pin
4. Grease the threaded steel upper link tubes.
5. Measure the length of the spring in the top link.

Verifying the Hydraulic Top
Link Setup
No Parts Required
Procedure
Extending the hydraulic cylinder increases the tine
depth.
1. Fully extend the hydraulic cylinder to determine
the location of the tine heads and to verify if they
contact the ground.
Note:
adjust the cylinder to maintain tine depth

(cresting a hill) but it will be necessary to have
the tine heads set about 5 cm (2 inches) below
ground.
•
If the tine heads contact the ground, turf
damage may occur.
If the tine heads contact the ground, adjust
the location of the cylinder ends to move the
top of the aerator closer to the traction unit.
•
If the tine heads do not contact the ground,
you can install extension brackets (included
with aerator) onto the top link to move the
tine heads closer to the ground.
2. Retract the hydraulic cylinder to lift the tine
heads.
Important:
do not to lift the aerator higher than is

necessary. Lifting the machine too high
will cause the PTO shaft knuckles to break

an angle of 25°, but do not exceed a 35° angle
when the aerator is at its highest position;
otherwise, severe shaft damage may occur.
