Combines drive adapters for 50 series combines

I don't know who makes them but I know they have the information for them at Greensburg Tractor at Greebsburg Kansas. They are basically a hex tube that slides over the hex header shaft with part of a pto adaptor welded to them. They won't work on contour master combines and your header must be new enough that the slip clutch is out by the end of the header. Or you would have to run without a slip clutch which I think would not be smart.

Your local JD dealer has them.

Harv's Farm Supply manufactures adapters and driveshafts of all types. They've got an ad in the attachments section.
