The SM420 tranny that I put in my '59 has a PTO.
There is a paddle grip that fastened to the stick shifter that appears to have had a cable attached at some time.
Since I have no idea what the tranny came out of and because it's incomplete, I have no history to venture a guess as to how it was used.
I've tried to google info such as diagrams, photos or illustrations for PTOs and I've come up empty.
I'm really interested in some inputs into this topic.
Glad you asked the question!
Jerry
