Just wanted to comment that in my personal opinion, the Snapper rear engine rider is one of the best built best cutting riding mowers EVER. I grew up using one that lasted over 23 years with original engine and another that lasted over 26 years with the original engine. I loved how they shifted. The single blade cut the grass the best. My favorite is the 33" blade hi vac deck. Your pics look like you have the hi vac deck.
When it came time to own my own riding mower, I searched for a Snapper rear engine rider frame with the 33" blade hi vac deck. I tore the whole thing down and rebuilt it. I used Snapper red factory paint as well. I put a "modern" 15 hp OHV Briggs engine on it, as everyone told me that was about the limit for that model (it just blew up and bent a rod). I wanted to put a 18 hp Briggs on it, but the experts said the transmission pullies could not handle the torque. You have a cool project.:thumbsup:
