I also posted this on the other Bolens site. I was wondering if anyone has compiled a list as to what models were made in what years I know it separates by serial number also. I would like to have a list in my pocket so I could figure out what year some of the RAM's I look at are. It would help on buying manuals also. Some of the sellers have no idea what year they have. I'm curious, that all. I am an ex-Ford parts manager, so I like to have all the info on what I'm messing with!
