When I was a "lad" back in the 40s, farmers sometimes complained that the H and M were not the equals of the F-20 and F-30 they were supposed to replace. I don't think it was so much a matter of actual horsepower, but of torque. The F-series had big engines, designed to run pretty slow. They had great torque, and would pull through even when overloaded. I remember trying to plow with an F-20 in FOURTH gear, and even though it would only get up to about 1/2 speed, it kept right on going. Don't fret, guys. I just did it for a coupla minutes--adolescent stuff. The H, especially, has a much smaller engine, designed to run faster. I used the same plow with two Hs, and they just didn't have the torque the old F-20 had. H of a lot nicer to drive (I guess that could be a joke, but it's probably not very funny). I never tried a 3-bottom with an M, but I think the complaint was around among farmers back then. An uncle of mine used an M in clayey soil and pulled only a 2-14 plow. I've spent some "quality time" with a Super M in the last few years, and I found it a really gutsy tractor for its size. I liked the higher speed in 4th gear, for travel on farm trails or pulling wagons on gravel roads, and I certainly liked the extra torque (partly from a larger engine than the regular M, and partly, I'd think, from a higher compression ratio). The original IHC hydraulic system on the M is pretty primitive. If the clutch is disengaged, you have no hydraulics. Independent hydraulics are really nice. I used to do a lot of "chore work" with the Hs (mowing around fences, bushhogging in tight places) and found them almost as easy to use as an F-12 that I had used before the Hs came along. The Super M is definitely NOT for one-finger maneuvering in tight places. Power steering would probably help a lot, but it is still a big, tall tractor. Delightful in an open field. Great sound, makes a little guy feel like he's flying a 747.

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
