Look at the torque of the engine as well. Look at horsepower and torque curves along the rpm range which both manufacturers typically publish. Also take a look at where the PTO speed is set/rated at what engine rpm. That will tell you the most. Lower RPM engines with equivalent HP typically develop more torque and in PTO work that's where the important number lies. A lot of companies substitute higher RPM to develop HP. Higher RPM engines are subject to a lot more wear and tear as well.
