1) The power rating of the engines indicated is the average net power output
(at specified rpm) of a typical production engine for the engine model measured to SAE standard J1349/ISO1585. Mass production engines may differ from this value. Actual power output for the engine installed in the final machine will depend on the operating speed, environmental conditions and other variables.
2) Refer to the engine manufacturer's owner manual for engine specifications.
