One just popped up on CL yesterday in town. 1970's Bonanza Pick-Up riding mower I remember there was a thread about them a bit ago. http://www.oldminibikes.com/forum/off-topic-discussion/83496-bonanza-tractor.html SimpleTom posted up some nice pictures of one and the ad to it. It's doesn't look bad but the engine is locked up on it and missing the deck. It still has the original wheels but missing some stickers.
