PROBLEM TO BE SOLVED: To enhance the workability of snow removing work by controlling the revolving speed of an engine in association with the set positions of a directional speed lever and a control lever for operating a snow removing section. SOLUTION: This snow blower comprises: the directional speed lever 53 for setting the advance/retreat and traveling speed of a blower body 19; a driving instruction switch 45 for giving the snow-removing section 13 instructions on the transmission of the power of the engine 14; a mode setting switch 51 for selecting an automatic position to automatically set the revolving speed of the engine and the traveling speed, or a manual position to manually set them; and a control section 61 for controlling the revolving speed of the engine and the traveling speed on the basis of information on the lever 53, the switch 45 and the switch 51. In the snow blower, the control section 61 controls the revolving speed of the engine 14 so that it can be increased up to a revolution range for snow-removing operations, on conditions that the switch 51 is in an automatic position, that the lever 53 is set in an advance position or a retreat position, and that the switch 45 is put into an on-state.
