摘要：

PROBLEM TO BE SOLVED: To provide a working machine capable of obtaining stable output corresponding to working conditions.

SOLUTION: The working machine driven by a drive control circuit 500, comprises a power source 15 set at one end of an operating lever, a voltage transducing circuit 101 transducing the voltage input from the power source 15 to output, a motor 34 set at the other end of the operating lever, power lines 5a and 5b inserted in the operating lever and applying the output voltage of the voltage transducing circuit 101 to the motor 34, and an implement working by receiving the power of the motor 34, wherein the operating lever and the power lines 5a and 5b are composed of longitudinally dividable and connectable units. A connection state detecting circuit 102 detects the connection state of the power lines 5a and 5b and the applied voltage of the motor 34. A calculating part 303 controls the output voltage of the voltage transducing circuit 101 based on the connection state of the power lines 5a and 5b and the applied voltage of the motor 34, detected by the connection state detection circuit 102.
