I have an original brochure, "The Farmall System of Farming," no date, but probably about 1942. I have somehow managed to keep it intact since I first took it off a dealer's info rack when I was a pre-teen. The brochure quotes speeds at 1650 rpm full-load governed speed, on 10-38 rear tires: The "special low-low speed (pneumatic tires only) 1-5/8 m.p.h."
"Special fourth speed (pneumatic tires only), 7 m.p.h." I don't have the no-load engine speed handy, but it might be around 1800 r.p.m., so the ground speeds would be proportionately higher if the tractor were not loaded down enough to bring the engine speed down to 1650 r.p.m. This higher fourth speed would make the tractor a lot more useful for some jobs around the farm. My father had two H's, both with the standard gearing. To pull a heavy load (hay, grain, corn) over a gravel road, you had to use fourth, which gave a little over 5 mph with the engine roaring full-blast. Fifth gear was useless in these conditions because the engine would be running at idle speed at 5 mph, and there was no torque to pull a heavy load (the IHC brochure quotes minimum speed in fifth gear as 9-1/2 mph, which means that the engine is running fast enough to give a little torque). The higher fourth gear would have given a nice "road gear" for the gravel roads. It would also have been useful for some field jobs, like pulling a spike-toothed harrow, with the engine maybe throttled back just a bit. The H was/is a lovely tractor, pleasant to drive, comfortable (for its day, at least), reliable, fairly agile because it wasn't as big and clumsy as its predecessor, the F-20, BUT the gearing was not as well-thought out as that of the JD and Oliver tractors, which had a fifth gear around 8 mph (VERY useful) and a "road gear" around 12 mph (plenty fast on gravel roads and on the trails through the fields).

Today's Featured Article - An AC Model M Crawler - by Anthony West. Neil Atkins is a man in his late thirties, a mild and patient character who talks fondly of his farming heritage. He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
