> Ranchers cut hay to get their pastured cattle through the winter. They can't have portions of their field unreachable by a tractor.

No one's banning hay fields. You can do both.

"The solar canopy also protects the grasses, keeping them green and dewy, even as nearby fields blanch and crisp in the sunlight. Shallanberger rotates the herd every few days, a key tenet of regenerative farming philosophy, so they munch on fresh grass while the rest of the field grows back. They move through all 15 paddocks in about 45 days; if the site relied on mechanical mowers, they’d trim every 45 days, too."

"Vegetation management is one of the most significant costs for solar plant maintenance in the Southeast, Shallenberger said. In the first six months, the cattle took care of about 75% of the mowing — he had to bring in conventional equipment for some woody weeds that the cattle don’t care for. Once the pasture is more established, the herd could handle up to 95% of the site’s mowing needs."

> Reasons like this are why this type of tech will always be popular on HN but they just can't figure out why farmers don't want it.

Farmers come in different sizes, shapes, locations.

The largest https://en.wikipedia.org/wiki/Cattle_station is several times the size of the state of Rhode Island, and chances are there're some spots where a bit of shade is welcome. I can also assure you no one's mowing/haying that size a property.

HN has a particularly severe case of 'I can write software, so I know everything' disease. It turns out all the farmers, electricians, engineers, bricklayers, bakers, policy experts, and so so much more should have just come on here a few times a week and they'd be so much smarter.
