PROBLEM TO BE SOLVED: To provide a riding working machine capable of reliably protecting an electric motor, which is used to drive a working device, while preventing degradation of working efficiency without an increase in a cost.SOLUTION: A riding working machine includes: a speed designation operating device which a driver maneuvers so as to designate a target travel speed of a machine; a travel control unit 54 that controls traveling electric motors 21 and 22 on the basis of the target travel speed; a working device with which work is performed on an object of work, which lies around a vehicle body, along with traveling of the machine; working electric motors 31, 32, and 33 with which the working device is driven; a work control unit 58 that controls the working electric motors 31, 32, and 33; temperature sensors 91a, 91b, and 91c that detect the temperatures of the traveling electric motors 31, 32, and 33 respectively; and an exceptional speed control unit 55 that implements exceptional speed control under which the traveling electric motors 21 and 22 are controlled at an exceptional speed lower than the target travel speed in a case where the temperatures detected by the temperature sensors 91a, 91b, and 91c respectively are higher than a threshold. |
