I did a search to find out.  Can't even mention where the info was found - I'd get points assessed just for naming the place.

 

Anyhow,  what I found is the engine is 3.5 times the PTO speed. 

Gravely set the governors at 3300 RPM.    That gives a PTO speed of  942 RPM

With the governor adjusted to 3600 RPM,   your PTO speed will be  1029 RPM

 

Your answer is [roughly]  "1000 RPM PTO"

 

If it doesn't have any more power than my own mower, a 1967 424 [previous model Gravely - 10 HP Kohler/50 inch deck],  its probably lugging along at 750 RPM.  I don't mind,  its just my trim mower for the tight spots.

 

Hope that helps.  Now I gotta go delete my cookies and history so no one finds out where I been.  :wave:
