Picked it up yesterday. Hopefully there's a picture attached. I'm guessing its an 83 as their's an 83 in the engine model #. There appears to be a AMF label, although to faded to read. So maybe it's not a real snapper anymore. Not real well built, sheet metal front axel, steering linkage a little worn, tranny is just the walkbehind snowblower type - spinning plate that a pulley rides in and out on for speed variation. Don't know if that's a good or bad think, seems to work ok, plus it has a high/low range. I strongly suspect though that only one wheel is driven . Engine runs fine. The blower is shaft drive, although there's a short v belt from the electric clutch on the engine down to the shaft drive.
Guess if I'm the only one on this forum with one of these, it makes me the resident expert!! Bring on your questions.
