There's also the trade-off between width of the worked area and the treaded surface made unusable for the season. If you have any tractor work steps between seeding and harvesting, you want all those runs done in exactly the same tracks to minimize waste. A "small robots" revolution might still come, on the coat-tails of agrovoltaics: if/when someone in the right position begins thinking the panel scaffolding as dual use, doubling as a "rail network" for robotic tools. I believe this could become a feature of agrovoltaics installations as unremarkable as overhead cranes on factory floors.
