4.24.4 SHANK PRESSURE
The hydraulic down pressure applied to the opener shanks is controlled by a closed loop
system that allows the user to enter the desired operating down pressure, entering the amount
of down pressure the system should apply on the monitor. 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.
1. To set and change the shank pressure, press any
soft key to bring up the soft key menu and press
“Shank”.
2. A horizontal bar graph display will come up on the
screen. Press “Enter” to activate the adjustment and
then rotate the spinner knob to increase or decrease
the system pressure setting.
3. Press “Enter” again to save the setting. When seeding this screen will show the system
pressure setting and a triangular shaped icon will move up and down the bar graph to show the
measured system pressure as compared to the set pressure.
