Working machine
First Claim
1. A self-traveling working machine in which electric motors are driven as a power source both by a power generator driven by an engine and a power storage means for storing a surplus power from the power generator, and a working device and a traveling device are activated by the electric motors, characterized in that the working machine is operated with an operation mode selected from a normal operation mode that the engine is operated over a high efficiency range with both an output from the power generator and an accumulated power stored in the power storage means, and a high-output operation mode that the engine is operated at a higher output than at the normal operation mode.

Abstract
A hybrid system working machine, during a normal working time, operated by a normal operation mode that the output of a power generator and the accumulated power of a capacitor are used while the engine is operated over a high-efficiency range at a low output. Switching of a selector switch to a high-speed running mode position and running operation enable long-distance and high-speed running of an increase in engine output by a high-output operation mode.
