Ferguson sold Waterloo Boy tractors at first then switched to the Fordson when he partnered with the Sherman Bros. and had his own duplex-hitch plow to go with it. After Fordson production went to Cork, Ireland he joined forces with David Brown. They built the Ferguson-Brown tractor, though not many, and despised each other until Ferguson snuck off to Dearborn in 1938 to demonstrate his new 3-pt lift system to Henry Ford. Using a Ferguson-Brown 1936 Type A tractor, he proved to Ford his draft control system was the best. Thus the famous 'handshake agreement' was born.
It was the practice of not only Ford, but all car makers to deliver trucks and tractors to the car dealers. They had to pay cash on delivery and often bankrupted the dealers. Considering that a dealer in downtown New York would have a heck of a time selling a tractor, the practice was dissolved eventually.
