I have plenty of blue prints, drawings and such and none of them where penned by Harry or Henry.

This is a silly argument and has nothing to do with the matter of who invented the 3pt hitch with constant draft control. Those are manufacturing blueprints produced by Ford/Dearborn draftsmen and meant for use on the factory floor. The only names that would normally be on such prints are the draftsmen's initials as well as the approving supervisors/engineers. They are manufacturing documents not "invention" documents.

On the other hand consider these two drawings which accompanied Ferguson's original 1920 patent application. Whether or not Harry actually "penned" the drawings may be in doubt but the name of the inventor submitting them and claiming the new and novel invention is crystal clear and prominantly displayed on the drawings. You can read the full patent application and Ferguson's assertion that he is the inventor along with a description of the theory and functioning of the mechanism here:

Patent Application US1464130A - Dec 15, 1920

This all began in 1920 long before Ford was invovled in any way shape or form. By the time Ford got involved (1938) Ferguson had already patented a number of modifications/improvements to the original mechanism including the use of a hydraulic pump and cylinder for raising/lowering the hitch. Harry Ferguson and his team, not Ford or Fords engineering and manufacturing department, invented and prototyped the first hydraulic 3pt hitch with constant draft control. In 1938 Henry Ford contracted to design and manufacture a tractor for Ferguson incorporating that invention and agreed to give Ferguson control of much of that design and manufacturing process.
