摘要
Providing an engine speed control device and an engine speed control method, wherein the no-load condition of the farm working machine can be estimated independently of the farm working machine and a no-loading operation condition of the engine can be automatically shifted to an idling condition. An engine speed control device with which the engine drives a farm working machine, the engine speed control device provided with: a memory section 8 in which the throttle opening threshold levels corresponding to the target engine speeds are memorized; a first judgment device that reads out the throttle opening threshold level corresponding to the target engine speed from the memory device, and judges whether or not the current throttle opening threshold level is smaller than or equal to the throttle opening threshold level corresponding to the target engine speed; a target engine speed determining section 16 by which the target engine speed diminishes to a low idling engine speed in a case where the first judgment device judges that the current throttle opening threshold level is smaller than or equal to the throttle opening threshold level corresponding to the target engine speed; and, a throttle opening regulating device 14 that regulates the opening of the throttle valve based on the target engine speed.
