I am not sure if the 50 shares this feature with the 65 or not.
On the 65 you can move the clevis pin on the clutch rod to the other hole that is provided. Doing so yields a lower clutch pedal BUT will not allow the second stage of the clutch to release.
So this may or may not help your situation.
Another fix is that you can adjust the 2-stage clutch closer together, whereas the second stage starts to disengage sooner. That would be done through the bottom inspection cover and you would adjust the gap on the three set screws to a lesser amount. Then you would have to readjust the clutch pedal rod to get the lower pedal height. Should you decide to go this route, it is important that the set screws are as close as possible to the same height.
Of course what I just told you goes against what you will read in the service manual, but a lower pedal is worth it to me.
