Near Intersection of I-35 & I-90 Southern Mn. | I think you have a good handle on what you need in your various situations. I also agree with the above reply.
As you appear to be aware, the Application Rate Module can be used in a variety of ways. 1) it can be connected to an implement switch and it can create a coverage map based on the implement switch. This will show applied acres but no rate. 2) it can be connected to a flow meter or shaft sensor, it will then create a coverage and rate applied map as well as applied acres and product total. The maps and totals start/stop based on product flow. 3) With a special cable the Application Rate Module can be connected to other equipment to share information back/forth. One example of that would be to connect an Ag Leader Application Rate Module to a Raven 440. The Raven would still run the application but the Ag Leader could make maps and send over variable rates from a memory card or stick.
So for the fertilizer spreader, you could just use it to make a coverage map with an implement switch or you could install a shaft sensor on the bed which would give you a coverage and rate map. This would be manual control as the Application Rate Module can not handle control or even section monitoring. The rig is considered as a single boom.
Another approach with the spreader would be to use another Ag Leader module called the Spinner Spreader Module. This would also require the SC 110 smart switch box or a dumb switch box and an Auxiliary Input Module. This arrangement would use a shaft sensor on the bed also and likely a hydraulic valve to control the oil flow to an orbit motor running the bed. The Spinner Module also has the capability to mount a sensor on the spinners so that you can watch their speed and adjust them manually. It is even possible to use a PWM hydraulic valve and have the Module control the spinner speed as well as the fertilizer rate.

As far as control on the Hardi, there are various situations. If your Hardi uses a two wire butterfly valve, the Liquid Product Module may work with it. The butterfly valve would need to have internal limit switches to prevent it from going "over center" and getting into the reverse control region. Many Hardis uses a positive displacement pump so for rate control and section control, the excess is diverted back to the tank. This makes plumbing in a flow meter difficult. There is the calibrated reflow approach for some of them. The system makes the assumption that the amount returning to the tank is equal to what would have been going out a boom section so it factors its rate calculations accordingly.

Looking for guidance making Ag Leader progression plan.
