Near Intersection of I-35 & I-90 Southern Mn. | ljadx160 - 3/20/2025 18:43
Charloz24, thanks for the pictures. I’m thinking of mounting the switch to the front bar, that would make for an easy short wiring to the clutch control module which I have mounted on a cross brace near the center post.
I use an Ag Leader Clutch Control Module and a Liquid Product Control Module both on my planter. Both modules have provisions for an implement switch. The idea is the system then knows whether the planter is UP or DOWN and can decisions based of the status. An actual implement switch or jumper is needed for Application. If I did not have an implement switch or jumper installed, my seed clutches would remain disengaged and my spray valves would remain closed. By using an implement switch instead of a jumper, raising the planter should guarantee that the clutches disengage and the spray valves close. The clutches may have already been disengaged and the spray already shut off but the implement switch assures this.
OK, so an implement switch is a good idea. There are several types. Deere makes one that fits over the parallel linkage of a planting unit. It is a normally closed switch which means when the planter is lowered to plant, the button is released which completes the circuit. Whisker type switches are another option and may be more reliable in certain situations and planter frame arrangements.
For my own planter, I have two Deere button switches with one on each wing and also a third branch that leads to the tractor. These three branches are wired in parallel meaning 12V from the Ag Leader module (Pin 12) goes to Pin A of each of the implement switches and the branch in the tractor. The opposite side of the switches (Pin B) tee together and lead to Pin 10 of the Ag Leader module or modules in my case.
This means if any of the three branches complete the circuit and send 12V back to Pin 10, the system will believe the implement switch is in the plant position. The reason I have two implement switches wired in parallel is so either switch can signal that the planter is down. If I only had one switch, it would be possible that the button on that row would get pushed causing an open circuit and the clutches would disengage. With two button switches, either can signal that the planter is down.
I also have a third branch leading to the tractor. The wire that is 12V goes to the input of a lighted rocker switch, The other wire goes to the output of the lighted rocker switch. A third terminal on the switch goes to a ground in the tractor so the light can work. The switch in the tractor cab is normally left in the OFF position so the real implement switches on the planter work as usual. When the switch is OFF but the planter is down, the implement switch(es) complete the circuit and the light goes ON. This means the light is an indicator as whether the implement switches are working properly. That light should go ON when the planter is down and OFF when the planter is UP. The switch also gives me the opportunity to override the implement switches for unusual situations. We can use the switch for testing and in some unusual situations where we back into a corner and don't want the clutches to have disengaged.
This may seem overly complicated but it works fine for us. Basically leave the tractor switch OFF, glance at the switch to see if its light is going ON/OFF if we have any doubt.

Implement switch - Kinze frame mount?
