the farming right to repair case is a different case than phones/laptops case imo. farming tractors are much more expensive and much larger. You can't mail a tractor in a bubble-wrapped envelope. I support right to repair for farm equipment because its their job on the line.

the mechanisms are much simpler in a tractor and mechanical in nature.

trying to do the same with other appliances could be dangerous or fatal if mistakes are made. farmers are literally hacking their machines (https://www.youtube.com/watch?v=EPYy_g8NzmI ) likely voiding warranty.
