I was just starting to kinda sorta start looking fir an old tractor with a snowblower and mower, something under $1000 like an old Simplicity to move trailers around, mow maybe when we didn’t both want to tackle it with two walk behind 21 inches, etc. well, I happened upon a very good condition maybe mint 817 with 50 in deck and blower. It looks like that model was made only in 1977 and has an Onan engine. Are these hard to find parts for and/or expensive to repair? It looks commercial and very heavy duty. What might it be worth? Asking is $1500. Could use some advice. I know nothing about garden tractors. Was going to look for a used XMark 48-52 in. hydro walk-behind but those are like $3000+ and so are zero-turns, although you can cut grass in a couple hours.
