Operating Instructions

Row-Pro™ is a factory installed option for implements
with 25 series openers that are equipped with
DICKEY-john

. It provides an automatic
adjustment for more consistent down pressure. Once
the springs are set, Row-Pro™ pneumatically
adjusts/reduces pressure on the openers.
There is one cylinder
for each row located between
the parallel arms. Based on loading on the side depth
wheels, Row-Pro™ adjusts air pressure in the air cylin-
ders.
Refer to Figure 168
There is one valve set per opener section, located in the
center of the section. It allows each section to be con-
trolled independently.
Note: For twin row there are two valve sets
per section:
one for the front openers and one for the rear open-
ers.
