Subject: RE: Wilmar Variable Rate

Near Intersection of I-35 & I-90 Southern Mn.
Yes, an Auxiliary Input module with a separate switchbox (single toggle switch will do in this case) or the Ag Leader SC110 CAN switchbox would be needed. The SC110 CAN switch box has a Master and 10 section switches for various options so it would be overkill for this situation but might be desirable for future uses. The two choices are functionally equivalent. You would choose one or the other. I happen to have the SC110 CAN switch box in my planter tractor for use with my planter. I have an Auxiliary Input Module in my Hagie sprayer so I can use the Hagie section switches.

One or the other of these are almost always needed with application type modules that deal with control of the rate such as the Liquid Product Control Module, Strip Til module, Spinner Module, Clutch Control Module for section control on planters, hydraulic drive for planters etc.

The Application Rate module would not require one of them but it is not capable of direct rate control.

As far as running the spinner with PTO and the spreader module, this is not a problem. The spinner portion can be setup 3 ways: 1) do nothing 2) monitor the spinner speed but do not try to control it or 3) monitor and control the spinner speed. This is done by running the spinners with hydraulics and using a PWM hydraulic control valve in the hydraulic plumbing. In this setup, the operator would enter the desired spinner speed and the system will adjust the PWM valve to attain that speed.

If you are going to continue to use the PTO for the spinners you would use either option 1) do nothing and just use the tractor's tach to run the PTO the desired speed or 2) install a sensor and wiring on the spinner so the spinner speed would be shown on the Integra. This would allow you to manually change the tractor's throttle as necessary.

As far as the applied rate goes, you could change this yourself by entering a different rate for different parts of the field or create a prescription that is saved to a USB stick. The prescription would contain the desired rates for the various parts of the field and the system would change to those rates as necessary. If you only have a couple of rates in mind, the manual method might be workable for you. If you have several different rates in mind for different parts of the field then the prescription route approach would be desirable.
