Engine Power Rating:

Kawasaki engines rated per SAE J1995 (gross) power testing with (98% + 3rd party verification) SAE J2723 labeling/rating Kohler and Briggs & Stratton rated per SAE J1995 (gross) power testing with revised (95%) SAE J1940 labeling/rating

Note that all engines are rated at full throttle and do not necessarily account for governor losses. Also, when mowing under heavy conditions, most operators will draw down the engine speed closer to peak torque speed where the peak torque ratings may be a closer indication of performance.
