Specifications are subject to change without notice.
* The power rating of the engines indicated in
this document measures the net power output at
3600 rpm (7000 rpm for model GXH50, GXV50,
GX25 and GX35) and net torque at 2500 rpm, as
tested on a production engine. 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.
