Installation: Hydraulic Down Force FAQ
Where do I plug in an implement switch?
Generation 1 modules will broadcast the implement switch status over the CAN bus. No additional
implement switch is needed.
What if I don’t have any other generation 1 modules?
You will use the Ag Leader CAN implement switch module P/N 4002911 and cable P/N 4002658 in
conjunction with the standard implement switch.
What if my cables don’t reach the rows for which I have installed gauge wheel
sensors?
It may be acceptable to choose rows the cables will reach, as long as channel 2 sensors are on the
center 6 rows, and channel 1 sensors are outside that.
What if I don’t have any free SCV connections for the down force valve?
Teeing into existing lines is acceptable. Do not tee into the vacuum fan line if adjusting fan RPM
on the tractor with a knob or dial. Teeing into the line before a flow limiter on the planter would be
acceptable. Teeing into the hydraulic drive supply line would be the best option. Do not tee into
Rawson Drive supply line.
What if my hydraulic oil gets too hot?
Ag Leader sells a Load Sense kit (P/N 4101225) to help manage oil temperatures. Note: This
system will not help if using SCV to control hydraulic drives. In this case, an auxiliary oil cooler
may need to be installed.
What if my hydraulic actuator does not extend far enough to reach the lower bracket
with row unit at bottom travel?
Purchase one spacer kit (P/N 4101201) per row. This will install at the bottom of the ram.
(Commonly used on John Deere long parallel arms)
My Kinze planter has rows that are offset 4” back, causing the upper actuator bracket
to not line up with the lower actuator bracket.
Purchase one spacer kit (P/N 4101204) per row. This will move the upper bracket 4” rearward.
How does the system know the difference between the row modules on channel 1 and
those on channel 2?
The Channel 1 row modules will connect to the cable labeled “Type 1” while channel 2 row modules
will connect to “Type 2” cables.
