To provide an electric working vehicle that can properly travel or start working, even in a state where a motor is rotating at a speed of 0 rpm or at a minimum speed.SOLUTION: An electric working vehicle is provided with: a motor M that drives at least either of travelling devices (10 and 11) and a working device; speed changers (38 and 39) that perform operation of changing a speed of rotative power for driving the travelling devices (10 and 11) or the working device; an accelerator operating tool 37 that performs operation of increasing/decreasing a motor rotating speed of the motor M; and a motor control part 54 that controls the motor rotating speed in accordance with operation to the accelerator operating tool 37. When operating the speed changers (38 and 39) and the accelerator operating tool 37 by an improper procedure, in a state where the motor rotating speed is below a predetermined first rotating speed, the motor control part 54 executes motor suppression control by which output of the motor M is restricted.SELECTED DRAWING: Figure 5
【課題】モータの回転数が0rpmまたは微小回転の状態においても、適切に走行または作業を開始することを目的とする。【解決手段】走行装置(10,11)および作業装置の少なくともいずれかを駆動するモータMと、走行装置(10,11)または作業装置を駆動する回転動力を変速操作する変速操作具(38,39)と、モータMのモータ回転数を昇降操作するアクセル操作具37と、アクセル操作具37に対する操作に応じてモータ回転数を制御するモータ制御部54とを備え、モータ制御部54は、モータ回転数が所定の第1回転数以下である状態で、変速操作具(38,39)およびアクセル操作具37を不適切な手順で操作した場合、モータMの出力を規制するモータ抑制制御を実施する。【選択図】図5
