Verifying the Hydraulic Top
Link Set Up
No Parts Required
Procedure
•
Extending the hydraulic cylinder will increase the
tine depth.
•
Fully extend the hydraulic cylinder to determine
the location of the tine heads and to verify if they
contact the ground.
CAUTION
If the tine heads contact the ground, turf
damage may occur.
Note:
On undulating turf, the operator can adjust
the cylinder to maintain tine depth (cresting a hill)
but it will be necessary to have the tine heads set
about 2 inches below ground.
•
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:
When connecting the PTO, be sure
that the aerator is not being lifted higher than is
necessary. Lifting the machine too high will cause
the PTO shaft knuckles to break (Figure 10). Never
leave the PTO turning when the aerator is lifted.
The PTO can be operated up to an angle of 25º, but
can never exceed a 35º angle when the aerator is
at its highest position or severe shaft damage may
occur.

Checking the PTO Angle
No Parts Required
Procedure
Important:
Make sure the tines are removed before
performing this operation.
With the aerator positioned on the ground and lowered
to the deepest location, check the angle between the
PTO and the aerator.
Lift the aerator and fully retract the hydraulic top link
cylinder. Using an angle indictor, check the angle
between the PTO and the aerator. If this angle is greater
than 35 degrees, make adjustments to the tractor so
that the aerator cannot be lifted past 35 degrees. This
can be accomplished by using the tractor lift stop (if
so equipped) or moving the lower links to a higher
mounting hole (if so equipped).
