This may be old news for some, but I've never seen anything here like this!
Cool car. It has the four wheel drive axles in the front and rear. My Pettibone has independent front and rear steering and that makes it quite maneuverable.
I had an old Pettibone with four wheel steering that would also allow both axles to steer the same direction so you could "crab walk" in and out of a tight situation. 3/71 Detroit Diesel powered. A brutal machine that would take everything you threw at it and ask for more. Good old American made muscle.
Yes a real work horse. Mine has a 471 Detroit but I think it was originally gas powered.
Here is a period accessory for the Model T which was available which had 4 wheel steering. The front and rear axles were joined with steering rods so the rear wheels could turn the opposite way to the front. The center wheels ( the differential) provided the drive as per normal T.
The Arnold system was used to allow the extended chassis to turn in tight corners.
In an old Vintage Ford magazine a photo was published showing a bus with the set up which was used in a European city which had narrow streets.
Here is a postcard showing it being used in Florida
Both Willys and Ford offered 4 wheel steer versions of the ubiquitous Jeep to the Army early in the Jeeps development in 1941, the idea being to decrease the Jeeps turning radius and enable the crew to exit tense situations more quickly, like when a German tank's turret was swiveling to bear down on you. The Willys version had a progressive disengagement so the steering was essentially standard at speed and only engaged at slow speeds. Worked very well, but used scarce parts like the Spicer axles too quickly and would interfere with the massive production ramp-up, so never entered production. Neat idea though.
