Farmers here are networked - not every farmer knows everything but almost all of then are two phone calls away from any required skillset.

Case in point, I work with local farmers and I'm deeply familiar with OS design, sheep shearing robotics, geophysical air survey, integrating sat + air + land data, sympbolic algebra systems, fixing old motocycles, automating pumps and irrigation, and a slew of other skills.

We've already got a local alternative non John Deere supply line for IT parts that often break (sensors, touch screens, monitors, etc) and for various mechanical parts.

Most people in the rural community know a FiFo (Fly in | Fly out) worker or three in mining | oil & gas which provides access to global state of the art mechanical workshops and automation R&D (see Rio Tinto + robotics).

The are many things that can be done by developing stand alone Tractor OS's - integrating drone cloud data and control for one, removing the John Deere "data spying" for another (all crop data gets phoned home to John Deere "for free").
