Moving out to deliver Ford Ferguson 9Ns... Ferguson supplied the revolutionary draft-control three-point hitch that he devised while Ford built a tractor to attach it to


The "Ferguson System" used a three-point implement-mounting arrangement with hydraulic lift and draft control that would eventually become an industry standard. Ferguson's three-point mounting setup used two solid lower links that did the pulling/carrying and a single top compression link with a control spring that exerted a downward force on the tractor. The action of the upper compression link helped to keep traction on the tractor's rear wheels and, by compressing and releasing the control spring, the link activated the hydraulic system, providing automatic depth control. Also, if the implement encountered an immovable obstacle such as a root or a rock, all hydraulic pressure was relieved and the tractor's rear wheels would begin to spin. This was a huge step forward in terms of operator safety, as it prevented the tractor's front wheels from lifting off the ground unexpectedly, potentially turning the machine over.

The tractor's overall dimensions should permit 14 of them to be loaded in a railroad box car for efficient shipping, Ford advised his engineers, and parts had to be drawn from existing Ford vehicles--this would keep production costs low and make servicing the tractors easy and inexpensive.

  1. These are not Fordsons. The Fordson of this era was a British tractor. These tractors are American Ford Ferguson 9Ns. I think the Ferguson part of the name was dropped after Henry Ford and Harry Ferguson fell out.

  2. Btw I found the link - it is on page 33 and says Ford 9N tractors. That is a 1939 Ford COE truck. With six tractors on board that little flathead V8 engine would have had to work hard for its living.

    1. Well, I need to remember that you look things up for fun the next time I'm stuck on a "what is it?" post!
      And thanks!
