Tractor hacking is growing increasingly popular because John Deere and other manufacturers have made it impossible to perform “unauthorized” repair on farm equipment, which farmers see as an attack on their sovereignty and quite possibly an existential threat to their livelihood if their tractor breaks at an inopportune time. “When crunch time comes and we break down, chances are we don’t have time to wait for a dealership employee to show up and fix it,” Danny Kluthe, a hog farmer in Nebraska, told his state legislature earlier this month. “Most all the new equipment [requires] a download [to fix].”
The nightmare scenario, and a fear I heard expressed over and over again in talking with farmers, is that John Deere could remotely shut down a tractor and there wouldn’t be anything a farmer could do about it. “What you’ve got is technicians running around here with cracked Ukrainian John Deere software that they bought off the black market”
A license agreement John Deere required farmers to sign in October forbids nearly all repair and modification to farming equipment, and prevents farmers from suing for “crop loss, lost profits, loss of goodwill, loss of use of equipment … arising from the performance or non-performance of any aspect of the software.” The agreement applies to anyone who turns the key or otherwise uses a John Deere tractor with embedded software. It means that only John Deere dealerships and “authorized” repair shops can work on newer tractors.
This behavior by John Deere is no different than the immoral behavior of Microsoft to its customers (which is why I use Linux). It is unacceptable and should encourage the rise of significant competition from other tractor companies.
