Dad is our sprayer operator, so I have little knowledge of sprayer controllers, etc.   The original Deere/raven controller in our 6500 doesn't appear to be working. Dad has just run pressures manually since we got the sprayer a few years ago.  

Wondering what are our options for replacing the original console?  If we would run a 2630 display for documentation and ATU steering, could a Deere GS rate controller be easily adapted to a 6500?  Or would it work to totally rework the system with a Raven 440 kit such as this, and run it to the 2630 for mapping/documention?  TIA
