I have an original IHC brochure for the H and M, from the early 40s. It says the M "will pull a 9-foot double disk harrow or other implements of similar draft requirements." They claimed three 14 or 16-inch bottoms, too, but my recollections of the experience of local farmers was that the original M's were pretty marginal for that kind of load. I've been away from active work on a farm for quite a few years, and the other fellows who write in have obviously a lot more information than I do about types of disks, number of disks, etc. The harrows I used back in the 40s and 50s had been made in the early 30s, and didn't have very big disks. Possibly less of a load than some of the big jobs of today. I do remember that freshly-plowed ground made a really heavy load for a double-disk harrow, especially if it was set rank to really dig in. Another thing to think about is that modern tractors are designed to pull their loads faster than the tractors of the 30s and 40s. Steel-wheeled tractors wouldn't pull their "rated load" above about three miles per hours because of huge power losses at the lugs. A lot of the advertising back in the 20s and 30s talked about "plowing gear," which was usually in the neighborhood of 3 mph. The next generation of tractors (M and other letter-series) were clearly designed to do their heavy work in second gear, like their predecessors, so we can't expect them to rip a big plow down the furrow at 4 or 5 mph like today's tractors seem to do. I don't know much about modern plows, but they may have different moldboard designs to make them easier to pull at higher speeds. (I'd like to hear from anybody who knows if this is true about modern plows; I'll monitor this site).

Today's Featured Article - The Great Escape - by Dave Hollrah. It all began Monday with a little baling of second crop on the lake shore field, and as I drove out past my sister and her hubby's place, this small calling sound could be heard from the general direction of their manure pile. Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
