Installation: Hydraulic Down Force FAQ
Am I missing something to plug into the 3 pin connector on the master hydraulic down
force module?
This connector is not used.
Why is the gauge wheel load bar graph constantly spiking and then going to 0?
This can happen if the Channel 1 pressure lines are routed to channel 2 sensors. Ensure channel
1 components (Down force pressure, and gauge wheel load sensor wiring) are on the wings,
and channel 2 components are on the center 6 rows. Ensure channel hoses are going to correct
channel of down force valve. Ensure PWM/pressure sensor cables are going to correct channel of
Down Force Module and Down Force Valve.
What are the red knobs on the down force valve?
This allows for manual adjustment of down force in the event of electronics failure. Push and twist
the knob to move between automatic adjustment (inner position) and manual adjustment (outer
position).
Why does the system need 3 hydraulic lines (Pressure, Return and Tank)
Under normal operation, pressure in the down force system is increased through the Pressure line
and relieved through the Return line. When the planter runs over a terrace or a water way, the
access pressure is released through the Tank line. All three lines MUST be connected.
