One thing that I've had a tough time wrapping my head around as I got interested in the early Economy's have to do with the different front axles they seemed to have used between the first tractor in 1946 and 1963...and it's been hard to determine when they used what.
There are still plenty of gaps in what I've figured out, but wanted to share at least what I have learned, observed and believe to be true. Feel free to help me fill in the gaps. I've posted pictures of the different examples based on my tractors but realize there are a couple variations I don't have pictures of.
-Cable Steer on the very early tractors and then Chain Steer
-"Wishbone" style front wheels/spindles on round tube axle with (3) positioning holes on each side.
-"Wishbone" style front wheels/spindles on square stock axle with (3) positioning holes on each side.
(1947 Chainsteer Ser # 338)
-"Wishbone" style front wheels/spindles on square stock axle with (2) positioning holes on each side.
-Chain Steer on "Standard Economy" or optional "Automotive Steering" utilizing a Ross steering gearbox and tierod for the first time on "Deluxe" and "Deluxe Electric" models.
-"Wishbone" style front wheels/spindles on a square stock axle with (2) positioning holes on each side.
(1949 Deluxe-Electric Ser # 1552 with "automotive" type steering)
-This is the first year that the previously standard "Chain Steering" wasn't available any longer.
- "Standard Economy" tractors still utilized the "Wishbone" style front wheels/spindles on the square stock axle with (2) positioning holes on each side but now come standard with the "automotive" steering utilizing the Ross steering gearbox and tie rod.
-For the first time now as an option, traditional style axle and spindles were offered with 12" bolt-on front wheels.
1952 - 1963:
-Traditional style spindles were standard now with 12" bolt-on front wheels. (16" rear wheel models however, such as Power Kings and Country Squires; utilized a slightly shorter front spindle to balance the height of the tractor.
(1952 24" Standard Economy with taller front spindles)
(1955 16" Red E with shorter front spindles)
The other Change that I've observed is the change from a "thicker" front tie rod to a "smaller diameter" front tie rod. I can't pin point yet, when exactly that change took place, but have narrowed it down between 1956-1959. Below is an example of the "smaller diameter" front tie rod on my 1960 Country Squire:
Hopefully this info is useful or interesting to others as I'm really intrigued by this kind of stuff.
