John Deere and other farm and heavy equipment companies plan to ask the U.S. Supreme Court to reject a New Hampshire law they say unfairly lumps their products in with cars and trucks, a lawyer representing the manufacturers said Tuesday. The high court on Friday denied their attempt to stop enforcement of a New Hampshire Supreme Court opinion that upheld the state's Automobile Dealer Bill of Rights law, which was expanded in 2013 to include protections for equipment distributors, in addition to auto and truck dealers.
