What rpm does a B pto turn. Maybe a better question is at what engine setting does the pto run 540 rpm. Thanks |

A good guess would be at 1400-1500 engine rpm. How do you tell the rpm? get a hand held, non contact tachometer. You can rev the engine, till the pto gets up 540, then check what the engine revs are.... Not trying to be a smarta$$, just delivering info...
