This is a 8 row 30" spaced sunflower header mounted on a 20 ft Gleaner L/M header. The make of the sunflower attatchment is unknown all i know is that my uncle bought it from a manufacturer out of North Dakota in the early 80s. THERE IS NO SUNFLOWER ATTACHMENT BUILT TODAY THAT EVEN COMES CLOSE TO THIS. You have no seed loss from this attachment. You can mount this attachment to any 20 ft header but it is really made for this header. I would try to get an adaptor to make this header fit you combine if it is of a different make.
