Operating Instructions
Refer to Figure 160
Row-Pro™ is a factory installed option for implements
with 25-series openers that are equipped with
DICKEY-john
®
IntelliAg
®
. It helps the spring down force
system to maintain a user-determined, ideal weight for
the side depth gauge wheels. Once the springs are set,
Row-Pro™ pneumatically increases/decreases pressure
on the openers.
 The row units are already getting their down pressure
from the springs on the parallel arms. Row-Pro only
acts to vary that pressure as needed to maintain
consistency in different soil conditions.
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
cylinders.
Refer to Figure 161
There is one valve set per opener section, located in the
center of the section. It allows each section to be
controlled independently.
 For twin row there are two valve sets per section:
one for the front openers and one for the rear
openers.
