Weve had this old BCS unit in the barn for years now. It came with the property when we bought it (a christmas tree farm) It dosent run and just has the shears attachment with it. The motor is made by ACME and has a gaurd missing off it but thats it I think. Id like to sell it and buy an attachment for my 4100 with the money (or get it running and use it this fall) What can you tell me about it?? I know nothing..
