7.7.3 Adjust Application Rate
7.7.4 Shank Pressure
The hydraulic down pressure applied to the opener shanks is controlled by a
closed loop system that allows you to enter the desired pressure. The operator
can enter the amount of down pressure applied on the monitor. The monitor
controls a down pressure valve that maintains the pressure setting on the open-
er 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.
The meter rate can be quickly adjusted while seeding by pressing the Meter
Rate Key. This brings up the Meter Rate Setting Screen.
1. Select the meter rate to adjust by turning the Selector Knob to highlight
the desired meter. Meter 1 is the default meter.
2. Press the Up/Down Navigation Keys keys to incrementally adjust the ap-
plication rate. The rate will immediately adjust for the selected meter. To adjust
another meter navigate to it with the
Selector Knob and adjust it up or down.
The Soft Keys will show all active meters. Pressing the Soft Key for a meter
will turn them on and off individually.
Press the Meter Rate Key again to return to the main operating screen.
