* The power rating of the engine indicated in this document is
the net power output tested on a production engine for the
engine model and measured in accordance with SAE J1349 at
7,000 rpm (Net Power) and at GX25/GX50:
5,000 rpm, GX35: 5,500 rpm (Max. Net Torque). Mass
production engines may vary from this value.
Actual power output for the engine installed in the final
machine will vary depending on numerous factors, including
the operating speed of the engine in application,
environmental conditions, maintenance, and other variables.
