Yep, here we go again, obviously, we'll still be fighting these problems 10 years from now if we don't ask the manufacturers, ASAE and ISO for some standardization like we enjoy on tractor 3Pt, PTO and hydraulic connectors. Brad Bish et al will help you out for now. His phone is 402-849-2674. They are the only company that might loose business due to header attachment standardization but he is already working on the next big thing.
