Original Ford Tractor Hand Cranks pop up all the time on fleabay. New, repops are also available at most Ford Tractor Parts suppliers including CNH (Case/New Holland) dealers. The picture below shows three of the tractor cranks. None will work on a tractor with a bumper. There is also a drawing on how to make your own -see below. The original cranks are 11/16" diameter, not 5/8" as shown in the DIY drawing. The 2N-17040-A2 shown was only for the wartime 2N models with the spinner handle and the spring loaded keeper so it wouldn't fall out. Cranks were sold in a shipping parts kit.
