Don't mean to take away the fun of flying down the road. I know that roaring down a country road on an H or M is like being in a Ferrari at 100 in a road race. Anyway, the "official" speed in fifth gear for an H is 15-5/8 mph at 1650 rpm, and for the M, 16-1/4 at 1450 rpm. This speed depends a little on the size of the tires. I don't have the high-idle speeds in front of me, but remember once estimating that these tractors would approach 18 mph at high-idle. I have strong memories of these tractors developing shimmy on rough roads, especially after the steering gear developed some wear. I eventually "grew up" enough that I was content to throttle back so the shimmy wouldn't develop. Fifth was never a very useful speed on a farm in the 40s and 50s. Our wagons were holdovers from the horse era, so they had steel tires. You couldn't do more than 5 mph on a gravel road without jolting everything to pieces and maybe even jouncing your load of hay enough to have some of it slide off. An H in fifth gear at 5 mph is running the engine at idle, and so it has no torque whatsoever. I vividly remember roaring along in 4th, wide open and doing somewhere between 5 and 6 mpm. I think IHC engineers saw an easy way to make a "gear" (a simple dog-clutch instead of a series of expensive gears). John Deere and Oliver had a better idea--put in a gear that would give about 8 mph full-throttle, and another that would give about 12, or maybe 7 or 8 throttled back part way, so there'd still be some torque available.

Today's Featured Article - Talk of the Town: Winterizing Engines - To Drain or Not to Drain? - by Russ Berry. What is this strange attraction I have to equipment and machinery? How did I get this way? I came from the suburbs and own a small horse farm in rural Loudoun County, Virginia. You can call me a "weekend farmer." The local farmers do. Does it bother me? No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
