IndianaRed, I do not have a definative answer, maybe someone else might. But I will take a stab at it with my speculation. The 400 was the end of the line of the M lineage for after the 400 the M was no longer a representation in the 450, but a morphed new tractor. The old 248 engine was replaced with a simular, but different 264. the hydrolics had been changed out to a newer and improved version with different controls TA and torque tube over the old non-TA version Ms. rear end was different in some respects over the M. A real LP designed engine, not a gasoline conversion. Basically the 450 was the first tractor that didn't have M designed compoents! It is as good a speculation as there is I guess, I maybe off base with my speculation, Better yet maybe Guy will chime in with his answer. I too would like to hear his view too. Later, John A.
