opener shanks. REFER TO SECTION 4.5, pertaining to the control system being used.
NOTE: 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 amount of down pressure the system should apply, can be done on the monitor as well.
The monitor controls a down pressure valve that maintains 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 equally.
