The article is B/S, You can buy dealer level diagnostic equipment for Deere AG Equipment, It's not cheap, And most Farmers will have no idea how to use it.
If you don't want to take your equipment to a Dealer.....Then DON'T, Buy a Laptop, And the Software, Interface, & Cable for your specific need & have Code Reading, Bi-Directional Controls, Live Data, Joystick, & GPS Diagnostics.
What in the world does that have too do with software that Retrieves, Edits, Writes & Rewrites Calibrations?
