Hello - new here. I have had my 1977 John Deere 400 about 2 months now. It came with a 60" mower and a snow blower, chains and weights. A clipboard of records and it's in good shape. I love the way it cuts, the power, etc. Have only recently had some problems - 1) Battery replacement, 2) Seat replacement 3) new mower blades and now the most recent - felt lots of vibrations and the mower driveshaft "fell" off and I'm unsure if it did damage. That same day one of the hydraulic hoses blew and covered a (now former) section of lawn. Local auto store built one very similar pretty quickly. But now I am just wanting to see if there is someone local in Mass that knows these machines and would be willing to just do a once over full inspection. I also cut that snorkle exhaust piece off.
