Cody: The history of these tractors is letter and early Super letter series started out with an Auburn clutch, very easy to push the pedal, however the Auburn clutch was not noted for it's longevity. Especially true after we started getting a lot of loaders.
In 1953, IH switched to the Rockford clutch much more durable, because they had more and heavier springs in the pressure plate. This also made the clutch pedal much harder to depress. Even on my little SA and 130. My 1953 SA was one of the last to come equipped with an Auburn clutch, while my 130 had a Rockford clutch. Even when you encountered those two clutches new on those little offsets, the Rockford was much harder to depress than an Auburn. When I changed my SA from Auburn to Rockford the difference was a 3 spring pressure plate to a 6 spring pressure plate. I expect the difference was even greater on a larger tractor. My SM, 300, 560, 504 and 656 all came new with Rockford, never had an Auburn clutch, thus I never experienced the difference. I do remember my dad commenting on the difference between H and 300 on loader work. They used to spread all the manure on 5 farms, with him loading 5 spreaders. I do remenber him complaining about his left leg after a day with 5 spreaders chasing him loading with 300.
My point in all of this, if you do a lot of tractor work, your left leg will thoughen up to the task. This is why I asked you, "compared to what other clutch"? could be a SC, a pickup, etc. Sure, you can check the lubrication on release bearing, pedal pivot shaft, however your never going to get a SM pedal to depress easy, relative to other clutches I mentioned.
