Title: Working machine

Abstract: A working machine has a machine body, an engine mounted on the machine body, an electric motor mounted on the machine body, a working part driven by the engine during a working state of the working part for performing a working operation, and a transporting part driven by the electric motor for transporting the working machine during the working operation. A control part controls rotation of the electric motor by setting a speed of the engine as a reference speed at a time at which the working state of the working part is initiated, determining a correction coefficient corresponding to a present speed of the engine from a correction characteristic having a correction coefficient corresponding to the reference speed of the engine, determining an acceleration of the transporting part in accordance with an actual travel speed of the transporting part, obtaining a corrected acceleration by multiplying the acceleration determined by the second determining means by the correction coefficient determined by the first determining means, and accelerating the speed of the electric motor in accordance with the obtained corrected acceleration.
