There's the Farmall "A", Farmall "B", Farmall "C" post 2012.   

It's a whole matrix on who made when where why and how!  Some of the A's made in India have the Shibura like the DX.  Some of the B's have a Mitsubishi and some of the C's have a Fiat!  I think the B's and C's are assembled in the US from foreign parts.  My 55C CVT is Fiat powered with DPF (not SCR like I stated earlier) and an Oerlikan CVT (all Italian). 

Anyways, I guess it is what it is.  At one point they had 3 Farmall 35's. 

I did do some reading Ron and there appears to be a large difference in the DX33's and the Farmall 35's.  Different engine size, different transmission, different frame.  It looks like the Farmall 35's have 200 cc larger motor and live PTO.  The DX had a single clutch to disengage the hydro and PTO.  Does yours have a live PTO?
