Abstract
An electric working machine has an electric motor and a speed adjustment member for undergoing movement within a range of positions including a low speed range position in which the electric working machine travels at a low speed, a high speed range position in which the electric working range position in which the electric working machine travels at a speed intermediate of the low speed and the high speed. A potentiometer receives a voltage which varies in dependence on the position of the speed adjustment member within the range of positions. A control unit controls the electric motor in accordance with the variation of the voltage received by the potentiometer to vary a travel speed of the electric working machine so that a rate of change of the travel speed of the electric working machine is smaller when the speed adjustment member is in the intermediate speed range position than when the speed adjustment member is in each of the low speed range position and the high speed range position.
