Claims

[Claims for Utility Model Registration] (1) A traveling working machine is configured to transmit power from an engine to a traveling device and a working part, respectively, and the rotational speed of the engine is set at a predetermined speed according to the load on the engine. A fuel supply control device is provided that automatically adjusts the fuel supply amount to the value of
A clutch sensor is provided to detect the N/OFF operation, and the power transmission to the working part changes from OFF to OFF.
When the detection signal changes to N, the fuel supply control device forcibly reduces the engine speed to an idling speed for an appropriate period of time, and then increases the engine speed to a predetermined speed. 1. An engine output control device for a traveling work machine, characterized in that it is provided with a control means for controlling. (2) The power from the engine of the traveling work machine is configured to be transmitted to the traveling device and the working section, respectively, and the clutch device for the working section is equipped with a clutch sensor that detects an operation to turn ON/OFF the power transmission. The transmission mechanism for the traveling device is provided with a shift sensor for detecting the shift position thereof, and the fuel supply amount is automatically adjusted so that the rotation speed of the engine becomes a predetermined value according to the load on the engine. A fuel supply control device is provided, and the fuel supply control device is configured to be manually operable,
When three conditions are satisfied: power transmission to the working part is OFF, the gear change position in the transmission mechanism is in the neutral position, and the fuel supply control device is in the automatic operation position, and the load on the engine is less than a predetermined value. , further comprising a control means for forcibly lowering the engine speed to an idling speed, while increasing the engine speed to a predetermined engine speed when the three conditions are not met. Engine output control device for work equipment.
