Instead of risking there tractors breaking down in the middle of harvest season and having to wait weeks for an authorized John Deere rep to service or fix there tractors, farmers are now jailbreaking them with cracked ukranian software. Even if they were to do repairs themselves, the tractors wouldn't work until they pay an authorized repair rep $230 plus $130/hr just to come out to plug in a usb drive that will authorize the parts. Along with Apple they are also fighting to right to repair bills pretty strongly in Nebraska.
