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.

Presswheel installed in middle position. 

 

 

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
