will parts from the M exchange with parts for the super M? Is the only difference the horsepower increase? I understand the transmission is different on MTA. Primarily interested in the hood,grill, drawbar, lights, and aftermarket 3pt hitch.

thanks
 
A 1952 Super M is basically nothing more than a souped up M (more bore) - except for gear ratios. All else is pretty much the same. Oh sure - the SM had a larger clutch, etc. but they were basically a souped up M.
It was not until the Stage II Super M in 1953 that more differences started showing up - including, mainly, live hydraulics.
As a result, the stage II SM's bring a little more brass than the 1952 Stage I versions.
Hood, grill, drawbar were the same. In 1953 - or very late 1952 - the lights changed to "flatback" sealedbeam variations. Very easy to distinguish between the two...
Aftermarket 3-point hitch would be the same. That difference depended upon whether either tractor had a two-way valve and whether or not the 3-point had two lines coming off of it.

Everything you mention will interchange between the M and SM but the grille may be a different style. The hood on the SMTA is longer. Lights are different also, but will interchange. SMTA has a torque amplifier giving 2 speeds in each gear. 2,3, and 4 are faster in the Super M and SMTA (direct), than in the M. 3rd in the SM and SMTA (direct) is about as fast as 4th in the M. 4th in the SM and SMTA (direct) is 1+ mph faster than 4th in the M.
