I mow with a 4 wheeled Gravely 816 with a 50" deck. It was manufactured in 1973 ! In the time I've owned it, other than oil and filter changes I've rebuilt the engine once and replaced the PTO & belt once. I'd say that's pretty good for a 50 year old mower. Gravely made a few 4 wheelers that will run a 60" deck. All attachments are shaft driven by a true transmission internal PTO. I fully expect this mower to outlive me. You could find a nice one with a 60" deck and 48" snow blower for about $3,000 The only Plastic on these tractors is a few bushings, the headlight lens and seat cover.
