After a years-long battle, a national group that represents farmers has reached an agreement with John Deere that would make it easier to do many tractor repairs. The agreement has been widely celebrated as a huge win for the right-to-repair movement, but the agreement is explicitly meant to be an alternative to  legislation, which would be stronger than this agreement. 

Deere and the American Farm Bureau Federation, a lobbying group that represents farmers’ interests nationwide, announced the memorandum of understanding Sunday.
