To provide a self-propelled crusher capable of restraining the temperature of cooling water from being elevated extremely.
A cooling process for driving a cooling fan 42 normal-directionally such that air passed through a screen 40 for restraining passage of a foreign matter in the air to generate a forward-directional air flow for supplying to a radiator 41, a maintenance process for driving the cooling fan 42 reverse-directionally to generate a reverse-directional air flow passed through the screen 40, and a load reduction process for interrupting a supply of an object to be crushed by a supply device at the time of the maintenance process, to reduce a load of an object-to-be-crushed engine 44 are executed, in the self-propelled crusher including the engine 44 of a power source, the radiator 41 constituting at least one part of a cooling function of the engine 44, the cooling fan 42 for generating the air flow passed through the radiator 41, and a driving means 43 for rotation-driving the cooling fan 42.
