Near Intersection of I-35 & I-90 Southern Mn. | This request comes up about this time each year.
As I understand your situation, you have an InCommand and a Hydraulic Drive Module which works with two hydraulic drives. One drive is for the left half, the other for the right half of your planter.
The hydraulic drive module allows you to change the population in different fields, within a field or even from one "side" to the other. You have a switch setup where there is a Master and a Submaster for each side. Normally three switches would be ON.
An implement switch is also involved. For normal planting, raising the planter at the Headlands, changes the position of the implement switch and stops the drives. After you turn around and drop the planter, the implement switch informs the system that this has happened and the hydraulic drives start turning again.
For point row situations, you could flip one of the Submasters off for areas that have already been planted. When you get to the Headland you raise the planter as usual and the other drive stops turning. For the return path some switch flipping would usually be necessary. This would be so the correct side comes on first and the other side somewhat later when you flip its Submaster ON. This might be tolerable if you only have a few situations like this. If you have many there is great potential for errors.
You would like this process to be automatic so that you do not need to flip the Submaster switches yourself.
Ag Leaders solution would be to purchase their Clutch Control Module, planter harness and clutches for each row or section. Then as point row situations occur, the Clutch Control Module would shut off rows or sections based on a coverage map. When the planter gets to the Headland, the Clutch Control Module will cycle all rows or sections OFF. Then when you raise the planter, the implement switch would stop all drives as before. This would involve purchasing a Clutch Module, wiring and several clutches.
Several years ago I worked as a Tech at a dealership that sold Ag Leader products. I also farmed and used Ag Leader product myself.
A long distance customer who I met here on AgTalk phoned me about his situation. He had a planter for corn and a different planting arrangement for soybeans. He had an Ag Leader display and switch box arrangement in his tractor. He had the hydraulic module and hydraulic drives as well as a Clutch Module and clutches on his corn planter. This was the usual arrangement that Ag Leader would expect and support.
He wanted to move the hydraulic module to his soybean planter for variable planting rates and could move the Clutch Module also. He didn't want to purchase a complete set of clutches for the soybean planter as he felt it would be cost prohibitive for the seed savings and reduction in doubling. He reasoned that there might be a way to use the Clutch Control Module to in effect "flip the Submaster" switches on his switch box for him.
Between the two of us we were able to come up with a workable modification to his switch box wiring harness. In essence the Clutch Control Module was wired in the "middle of things" and could then break the signal from the original Submaster switches. That way the operator could just leave them ON and the Clutch Module would in effect flip the Submasters ON/OFF for him based on the coverage map. Thus the drives would not deliver seed in areas that already been planted.
His system used the Ag Leader dumb switch box and an Auxiliary Input Module so my "adapter harness" went between the two. This idea could likely be used with the SC110 switch box and the often unused Brown Connector stub. I have never actually done that but the overall scheme would be the same.
This approach although workable would not be approved nor supported by Ag Leader. I suspect it would be discouraged as it would be a nonstandard approach. Its advantage could be saving the cost of several clutches. Its disadvantage would be that a Clutch Module would still involved and that an entire side would be cycled OFF only when all rows had been covered. This would not result in as much seed savings as using actual clutches. Also the approach would require a decent understanding of how the Ag Leader inputs work as well as relays, diodes etc. Although these concepts are not difficult they may beyond the experience of many.
Even though I was involved with this, I can't in good conscience recommend it.
