Which John Deere lawn tractors fit my old 42" snowthrower # OMM133878 F2

[dave678]

Hello, my LX255 tractor is getting very tired & beat up, so time to replace it. Thinking a LX277 with 42" mower in good shape but hard to come by here in southern Wisconsin. My snow thrower manual says for LX and GT's, wondering if it fits anything newer. Need to broaden my search. Your thoughts and suggestions are appreciated. Sincerely, Dave Branz
