It's called a "Poulan/Weedeater 22" " rotary mower with a Briggs SQ 4.5 HP. I just bought it at a yard sale today. It wasn't supposed to run. I cleaned it up, cleaned the spark plug, put fresh gas in it, and it started. Cut the lawn with it just a few hours after buying it. I thought it would be nice to have a downloaded copy of the manual. The Poulan website doesn't recognize the model number for some reason. I don't know the vintage but it doesn't seem to be that old.
