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

. 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
cylinders.
Refer to Figure 165
There is one valve set per opener section, located in the
center of the section. It allows each section to be
controlled independently.
