What were the differences in the 2 tractors besides hydraulics, 2 pt hitch and sheet metal? Did they have the same motor?

Same cubes, the 400 had slightly higher compression, which gave it a couple more horses.

Power steering became available with the 400. Six spoke wheels were replaced with eight spoke wheels several months after the 400 was introduced. Tachometers were also available some time after the new model introduction. Pull type starter switch was replaced with a solinoid.

About $2,000-4,000 dollars....

Steering supports and throttle linkage, battery boxes, clutch pedal, fuel tanks, air cleaner gas models, IPTO operating handle, radiators and fan shrould, transmission top cover and shift forks, starter, wireing and gage locations. Early F 400 used the same rear cast wheels, t/a operating handle and engine block cast # as a SMTA. later 400 used slightly different parts.
On gas engines the 400 used a different head, manifold, valve cover, camshaft, carburetor, distributor advance set up, and some other small things. Later 400 used different connecting rods, pistons, piston pins, camshaft gear and not to far into production a dipstick in engine block was added.
Diesel engines had very few changes except part of 400 tractors used a B type injection pump and the last few came with open type injectors. Max horsepower tests for a SMD and a F400D were the same or fractions different for the two.
Probably forgot something. Yes gear shifter and generator mounting braket on part of the 400 tractors.
