Installation
The Parallelogram Presswheel has been de-
signed to fit into a Gason HydraTILL tine.
First, fully raise the implement. The assembly
is installed by pinning though the shank and
cast pivot bracket then tightening and lock-
ing the two M20 set screws. From factory the
pin will be installed in the middle hole in both
the pivot bracket and the shank and the set
screws will be locked loose (for ease of ad-
justment). The mid position will give approx-
imately 750mm under-frame clearance
(UFC), depending on the point used. The UFC
can be adjus
ted in 12.5mm (1/2”) incre-
ments.

Care should be taken to ensure each
Parallelogram is set in the same holes
(same UFC).
Ensure the two M20 set screws are
tightened hard against the shank and
locked with the nut prior to use.
Torque Specifications
Caution:
Torque values listed on the
following page should be used as a guide
only. If a different torque value or tighten-
ing procedure is specified for a specific ap-
plication, do not use these values.
Refer to the Parts section for proper grade
and length of bolts for replacement parts.
Do not replace Nyloc nuts with nuts and
spring washers. Replace all parts with origi-
nal specified parts only (note fastener
grades).
The following torque figures are those rec-
ommended for zinc plated, lightly oiled
bolts. Recommended assembly torques may
be obtained by multiplying the torque fig-
ures in the table below by:
0.78
–
for degreased zinc plated bolts.
1.10
–
for black oxide finished bolts
