Zach B. is probably onto something. The tractors sold on steel had the 5th "gear" locked out by a long bolt that simply kept the shift rail from moving forward when the shift lever was pulled back toward fifth. Here is a quote from an early sales brochures (maybe 1940 or 1941): "Four ideal working speeds, with manual governor control, provide perfect adjustment of speed--a perfect gait for every field job. The fifth, or high speed built into the rubber-tired tractors is a real time and labor saver on the road." Sounds like the transmissions are built differently, but they are not. If a steel-wheeled tractor was converted to rubber, it took about 2 minutes to turn the locking bolt out enough to let the shift rail move forward. I don't know whether people put a lock nut on top or not. Probably most people and dealers would just get a shorter bolt from the hardware store so they could run it down tight into the transmission cover. I've often wondered if an H on steel would even have enough power to move the tractor in fifth. It would be some ride if you gave it enough gas so that it would move (the specs call for 9-1/2 to 15-5/8 mph in fifth, which suggests that the engine has to be revved up part way to get enough power to pull anything). I remember the Hs we used that would pull almost nothing in fifth at the speeds you could use with a steel-tired wagon on a washboard gravel road. The engine was running so slowly at 5 or 6 mph that there wasn't enough torque. You had to resort to fourth wide open (noisy!) to get between 5 and 6 mph. I used a couple of steel-wheeled tractors for at least 10 years, and I remember VERY WELL the bone-shaking ride on hard ground or roads if you went even 3 mph. I would usually go on the road in second gear, throttled back. Otherwise, the tractor did a St. Vitus dance and you HAD to stand up. Steel wheels waste a lot of power, and apparently more power the faster you go. Our 10-20 would do NO heavy work in third (about 4.25 mph)--no plowing, no disking--but it would work through anything in second (the old "plowing gear," which I think engineers calculated to give enough power to pull the "rated load" of a certain number of plows; most tractors of the 30s and 40s seem to have had a "plowing gear" around 3 mph).
