Early M's had a larger oil filter element and canister, usually came with the dual fuel carburetor, and had a small starting tank for gasoline and a second tank for Kerosene or Distillate, the lower compression head to allow it to run the lower grade fuels, a different fuel tank support, a lower pressure belly pump, a slightly different setup for the steering shaft center bushing, a different cast front end assembly that used more cast and shorter channel pieces, non-adjustable front wheels (the adjustable were optional), a different PTO unit that did not necessarily run at 540 RPM, A different transmission fork assembly, Different seats, the shift pattern cast into the differential top cover/ platform (later ones just got a sticker), Non-pressurized radiator (later models were pressurized), different sheet metal using Dzus fasteners instead of bolts, and the electrical system of the later tractors used a regulator instead of a simple cut-out relay. Those are all of the differences I can think of off hand, I am sure there are more.

Extra horsepower came from the higher compression head that became standard on the later M's. Early M's could kerosene, gasoline, or distillate. Later ones could run only gasoline unless a different fuel was specified when the tractor was purchased.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract. ... [Read Article]
