Help!!! We just bought a used backhoe attachment for our john deere 4100 and can't get any answers to what model it is.I've contacted Koyker with no help with the numbers.Tried to contact Kelly manufacturing suggested by Koyker with no response.Can anyone guide us in the right direction so we may accuire an operators manual? ThankYou very much.We think by lots of research that it may be a B600.
