192 c.i.d. engine vs. 201 engine

[Mace Canute]

The 192 was not discontinued in 1968, it simply was not used in 4000's. Big difference.

The subject tractor is a 4630, not a 4000.

OOPS! I just clicked on the link wedge40 provided without doing my own search. Bad wedge40! Bad! :laughing::laughing::laughing: (Sorry, couldn't help myself )
