John: They are quite similar but depending on Super A serial number, and if it's still factory original there will be various differences. Several upgrades were done during the Super A production run from 47 through to 54.

The front end got quite a make over in 1951, changes in steering box and it was changed to automotive type tyrods. The front wheels changed but that happened before 51. At serial number 310000 the block changed, giving SA same block as SC. The SA continued to be 113 cubic inch using thicker sleeves than SC with 123 cubic inch. At serial number 336711 the cooling system changed to presurized yet remained thermosyphon. At serial number 356001, displacment was changed to 123 cubic inches, water pump was added along with a larger radiator. In the time leading up to serial number 356001, minor changes were also made to brakes, final drives, hydraulics. From then on until end of production it became known a Super A1, and only 1,957 were built. By the end of production the Super A1 was basically a Farmall 100 with SA sheet metal.

Basic design never changed from A in 39 to the last 140 in 79. However in the evolution, probably more change occured during Super A production than at any other time.

The 100,130 and 140 went on to have single point fast hitch. Some claim a few SA had fast hitch, I wouldn't want to argue that one either way. With the increased power came larger tires, and that evolved also depending on the user A and early SA had 9.5x24 and by 140 11.2x24 was common and even a few 12.4x24.

After that the changes were minamul. 140 went to an atuomotive type water pump on fan hub. It had pressed steel front wheels, went to 12 volt mid 60s and later to 12 volt alternator During the last few years of 140 production the pull rod starter changed to solinoid and key start.

I've probably missed a few things. By the way where does John Wheeler hail from, and what was his dad's first name? Just a shot in the dark, but I knew some Wheelers when I was much younger.
