I bought this tractor for $1,000 about a year and a half ago from a fellow who was storing it. It has a Briggs and Straton 18.5 hp engine - and it ran great until a couple of months ago when it wouldn't start - I replaced the battery, plug, filters etc and it still wouldn't start - after browsing the web, it seems most likely that is needs a new camshaft - I'm not a mechanic, and don't have the tools to fix it - on youtube lots of folks with a decent set of tools can fix this, the parts aren't that much <$40, but I'm not one of those people.
Otherwise it's in great chape, I bought a new trailer for it, tires are good -and this is model that has a single pedal for speed control (forward/reverse), replacing the older, sometimes cumbersome, manual speed lever found on older models.
You'll have to figure out how to move it up a small hill -
