SEED HAWK ® 2014 30 SERIES OPERATOR’S MANUAL – DOMESTIC 62
5.9.1 Opener Shank Pressure Adjustment
The hydraulic down pressure applied to the opener shanks is controlled by a
closed loop system that allows the operator to enter the desired operating
down pressure. Entering the desired amount of down pressure can be done on
the monitor as well. The monitor controls a down pressure valve that main-
tains the pressure setting on the opener shanks through the control module.
A pressure sensor measures the actual hydraulic pressure and feeds it back to
the control module. The control module adjusts the down pressure valve to
maintain the system setting. As the openers move up and down, with the terrain,
constant force is applied to all openers equally.
