Farmer Nick Welker ’s tractors steer themselves nearly as effectively as the latest Teslas.
They were built in the 1970s.
Welker has spent years outfitting the machines with satellite-guided steering systems, giving him cutting-edge technology without spending $700,000 for a new tractor.
The last improvement two years ago on his 52-year-old tractor cost $20,000.
