Introduction 

 

 

AF Gason Pty Ltd (Gason) is an Australian 
owned family business operating from within 
rural Victoria. The Gason Company has been 
servicing the needs of rural Australians for 
over 75 years. We operate through a local 
dealer support network that spans the coun-
try. Gason would like to thank you for pur-
chasing your Australian made tillage attach-
ment, and trust that you will have many years 
of trouble free service. 
 
The Gason Parallelogram Presswheels are a till-
age implement attachment that offers in frame 
mounting of presswheels to individual tines for 
improved seed placement, seed/fertilizer sep-
aration and seed to soil contact. 
 
Some  features  of  the  Gason  Parallelogram 
Presswheel include: 
 

 

Mounts direct to Gason HydraTILL tine. 

 

Height setting variable for large range of 
under frame clearances.  

 

All pivot points use greaseable hardened 
bushes. 

 

Aluminium split rim that allows fitment 
of different tyres, varying in tyre width, 
profile and construction. 

 

Adjustable tyre down-force. 

 

Optional adjustable mud scraper. 

 

Adjustable Sowing Boot. 

 
 

Field experience has shown that a good under-
standing of the implement and its attachments 
greatly reduces problems in the field. 
 
 

Prior  to  use,  please  ensure  the  manual  has 
been read and understood. 

 
 

This presswheel may not be suitable for all soil 
conditions  throughout  Australia.  When  pur-
chasing these attachments please conduct suf-
ficient research to ensure correct operation in 
your  local  conditions.  Presswheels  of  any  de-
scription  will  have  an adverse  effect  on  trash 
flow.  Stubble  management  at  harvest  is  im-
portant  for  successful  operation  of  press-
wheels at seeding.  
 
Only the primary shank of the Parallelogram 
Presswheel is to be used for engaging un-
worked ground. The Parallelogram Presswheel 
sowing boot has been designed to be a sec-
ondary seeding device, it should be adjusted 
high enough that it only engages loose soil. If 
not, premature wear or failure could occur. 
The Parallelogram Presswheel should not be 
worked in rocky ground.  

 

Important:

 Warranty will be void if working in 

rocky ground.
