M-Series Notes:
Suffix "1 models are the second generation "Wide Cab tractors. Cab is 5.7 inches wider than first models.
Suffix "2 models are factory equipped with 540 / 1000 RPM PTO kits. M95S and M105S:
The "S represents the model/tractor class in general is no specific meaning, however it can be applied to "Swing Shift as the base transmission on all "S models.
M50-Series 1983 - 1984 Cab was orange in color, air conditioning was optional.
