Abstract
A stop system for an engine of a work machine includes an engine stop control unit and an engine stop control suspension unit. The engine stop control unit, in a case in which there is a stop instruction that instructs to stop the engine of the work machine, performs delayed stop control to delay the stop of the engine until a predetermined condition is established, and then stops the engine. The engine stop control suspension unit, in a case in which there is a cancellation instruction to cancel the stop instruction, suspends the delayed stop control when work equipment of the work machine is in a locked state, and continues to perform the delayed stop control when the work equipment is in an unlocked state.
