It’s the correct speed if you have it too slow you will brake too many sheer pins

Good day At 72 stokes /min , I think that is fast. Wow steel won't stand up to that

Agree does seem rather fast.

Yes, baled with a B46 when I was a kid. This is more than 540 RPM on the PTO. That David Brown Cropmaster has two speeds on the PTO. Looks like he has it in the high PTO gear. The Cropmaster delivered 540 RPM on the low PTO at 1450 Engine RPM and 1000 RPM on the high PTO at 1810 Engine RPM.
