Verifying the Hydraulic Top
Link Setup
No Parts Required
Procedure
•
Extending the hydraulic cylinder increases the tine
depth.
•
Fully extend the hydraulic cylinder to determine
the location of the tine heads and to verify if they
contact the ground.
Note:
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 tractor.
•
If the tine heads do not contact the ground,
extension brackets (included with aerator) can be
installed to the top link to move the tine heads
closer to the ground.
Important:
that the aerator is not being lifted higher than
is necessary. Lifting the machine too high will
cause the PTO shaft knuckles to break
Do not leave the PTO turning when the aerator
is raised. You can operate the PTO up to an
g010966
angle of 25°, but do not exceed a 35° angle when
the aerator is at its highest position; otherwise,
severe shaft damage may occur.
