[AT] David Brown was Allis Chalmers ED40 3 point hitch

[James Peck]

Ford claimed to be losing money but that may have been a ploy. I am guessing that new Ford President Henry Ford 2 was clearing the deck of the older men who had been his grandfather's picks: Sorensen, Bennet, and Ferguson.

Both parties benefitted from the joint venture. Ford ended up with the 8N which had some real come from behinf market share. After they tweaked the NAA hydraulic design thater wer sno more3 point  patent infringement worries.

Ferguson  ended up a two continent tractor manufacturer. He was obviously anticipating the breakup.

Eagle Hitch and Fast Hitch morphed into three point hitch. It was Allis Chalmers with their knock off of an earlier Ferguson hitch that was the oddball. 

Dean VP Snohomish WA 98290 Deerecentric AT List Member (deanvp at att.net); Everything I have read on the breakup of the relationship between Ferguson and Ford was primarily related to economics.  Due to the financial details of the handshake agreement Ford realized that Ferguson was making more money on each N series tractor than they were. In fact The N Series was possibly not profitable at all for Ford any more. Ford needed to get that corrected.
But the way they tried to get it corrected cost them almost $10 Million in the Ferguson litigation settlement in 1952. But... that settlement allowed all manufacturers to use the 3 point system on their own tractors without royalties.  This was the beginning of  the end of the era of proprietary hitches which the farmers eventually rejected.
