I have a Troy Bilt Pony that works well. I also have my grandfathers old, old Roto-ette Model 2 (Rototiller Inc.) that was the forerunner of the Troy Bilt tillers. It has the blade disc tines instead of the digger tines that were made from hardened round stock. The old tiller wasn't used much, engine threw the rod in the mid 50's, the engine was removed for repair in the workshop of the barn and the barn burned down, losing the engine and step pulley. That old tiller has been in the corner of my garage for 51 years. I have replaced all the old rawhide seals, found a new set of discontinued knobby 7" tires and tubes, cleaned and repainted (twice) over the years. Can't bring myself to junk it, the tines still have the factory grinding marks visible. I guess it is a 53 or 54 model year, the last I can remember it running was spring of 1957.
