Might be a crazy idea but maybe they can just use smaller tractors. I'm not sure if we have the technology to build Smaller tractors. But since they are needed maybe there could be a Lot of R&D to make a tractor that fits under the space available in these installations.
Small tractors are easy. The issue is efficiency. The big tractor is big because the tool it pulls behind it covers ~10 rows per pass. You can easily build a small tractor that does 1-2 rows per pass, but that means you need a lot more passes, which means doing anything takes a lot longer.
