＊ 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: 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.
