<p>An engine control device for a working vehicle, having a hydraulic pump (2) driven by an engine (1), a hydraulic actuator (5) driven by pressurized oil from the hydraulic pump (2), a drive prohibition means (3) for prohibiting the drive of the hydraulic actuator (5) by the pressurized oil from the hydraulic pump (2), a drive prohibition detection means (14) for detecting operation/non-operation of the drive prohibition means (3), and speed control means (12-16) which, at least when the operation of the drive prohibition means (3) is detected by the drive prohibition detection means (14), controls the speed of the engine (1) to a low rotation speed (NS) lower than a minimum rotation speed (low idle rotation speed (NL)) that can drive the hydraulic actuator (5).</p> |
