Enabling this option will disengage active control (hold) when any portion of the planter enters
a no plant zone, such as boundaries, or previously planted areas. Use caution with this option if
planting long point rows. Alarms are disabled when system is in hold.

Hydraulic Downforce
Manually entered values depicting
tractor’s hydraulic pressure. Values shown
are for a 3000 PSI system (most common)
Select Channel to Calibrate
1. Set Point: Enter value here that matches value displayed on the corresponding channel’s
mechanical gauge attached to Ag Leader Down Force valve. (This can be done at 0 PSI)
2. Slope: value is dependent on manufacture of pressure transducer. Use 0.75 PSI/mV for
transducer supplied with valve.
Pressure Sensor Enabled: must be enabled to display “Down Force” on run screen.
Duty Cycle
Minimum/Medium/Maximum: Manually entered values correlating PWM duty cycle to
hydraulic pressure supplied to Down Force actuators. Values shown are for the Ag
Leader supplied hydraulic down force valve.
PWM Frequency: Number of PWM signals per second (Hz)
Row Unit Sensors
Enabled sensors will be used to calculate required supplemental down force

Gauge Wheel (bar graph): Each bar displays gauge wheel load for monitored rows
Down Force (bar graph): Each bar displays supplemental down force for monitored
rows
Down Force
a. Gauge Wheel: Planter average gauge wheel load
b. Down Force: Planter average supplemental down force
Planter Options - Down Force tab
Status: displays current status of control system
Active: System is actively controlling down force
Inactive: System is not actively controlling down force
Hold: Pressure is being held constant due to manual hold or
automatic hold
Gauge Wheel: Instantaneous channel average gauge wheel
load
Down Force: Instantaneous hydraulic pressure
Pressure: Pressure reading from corresponding channel
pressure transducer
Gauge Wheel By Row (table): Instantaneous gauge wheel load
for each monitored row
Automatic Control (button): Active down force control mode.
Gauge Wheel Load: User selected aggressiveness. Higher
aggressiveness will equate to higher gauge wheel loads
Manual Control (button): Allows user to manually adjust
pressure supplied to down force actuators across planter. Active
down force is disabled when in this mode.
