. 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 163
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.
