Near Intersection of I-35 & I-90 Southern Mn. | You are correct in that the Application Rate Module does not allow sections. It can be used with an implement switch to just start/stop coverage mapping. It can be used with a flow meter or shaft sensor to record/map application rates. It can be connected to a third party controller such as a Raven 440 with a serial cable to allow the two to work together.
We use one for monitoring but not controlling starter fertilizer on our planter with a flow meter in the fertilizer line. We use another one on our manure rig but our manure situation is different than yours.
We have a Yamatake mag meter on a hog manure liquid rig. It is connected to the Ag Leader Application Rate Module and provides a pulse output that is indicative of the manure flow. Its pulse output is similar to a flow meter in a spray system. The App Rate module starts/stops rate calculation, rate and coverage mapping base on activity from the Yamatake. This gives nice maps and various totals etc.
In our case, the rig is centered on the the tractor and only one section so the Application Rate module works fine. I was able to repurpose a damaged Application Rate Module for this purpose. My modified wiring arrangement was literally "outside the box" since damage had been done due to back feeding or a dead short across the flow meter power wires.
I believe that a Liquid Product Control module setup with two sections and the right half always off should show proper mapping and might be worth a try if you had one already for another purpose. The Liquid module would need to be "fooled" by a PTO sensor or some other device to produce some type of fake flow.
Using auto steering might require some modification. Auto steering would be normally be set to the implement width which in this case might be 2 -50' sections or 100'. The AB lines would then be 100' apart. I believe it would work to override the implement width setting and reduce it to 50'. I'm thinking you would then have a guidance line every 50' and you would just choose the one that is appropriate for each load.
Maybe I'm overthinking this. Possibly just messing with the GPS left/right offset will do the trick.
