What's the Difference?

Between the Sovereign PS and non-PS steering arm besides one is NLA, undoubtedly more $, one has a hole, one has a stud, and there aren't 10 or 15 of one of them in my parts pile? Distance of hole/stud from vertical shaft? Angle of arm from keyways? Anything else??

These should answer your questions:

Looks like the shorter leverage is going to be the primary difference since the power would make up for it and take advantage of the higher speed/different throw.

The difference is the stud is moved 1/2" closer to the spindle so that the heim joint will not hit the frame when turning. That is what I had to do on the ones that I copied. You can also use a shoulder bolt through the heim joint and a nut at the bottom.

Thanks for the photos Bill. They answer my questions well. I would guess another reason for moving the stud inward might be to provide more clearance for the cylinder from the tractor frame.
