TECHNICAL SPECIFICATIONS
* Values in brackets: machine fitted with 3-tooth disc, 4-tooth disc.
** The power rating of the engine indicated in this document is the net power output tested on a production engine for the engine model GX25T and measured in
accordance with ISO8893 at 7 000 rpm (Net Power) SAE J1349 and 5 000 rpm (Net Torque max.). 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.
