To solve a problem that, while a term marginal village or the like has come into use in the media, development/wide-use of a handy snow-plow has become a social demand because an existing machine, being self-travelled, is huge in structure, complicated and expensive and requires a professional operator as there are not many strong skilled laborers capable of clearing snow from an off-street/roof in a snow region.

A operating machine portion 2 (mowing and driving parts) is removed from a mowing machine having a handle 3 for retaining by man-power and an engine 4 as a driving source, and then a new mechanical part 1 is attached. The new mechanical part 2 is allowed to have a function as a vibration generator by eccentrically providing an impeller rotor, so as to vibrate a rotor case and crush the snow pressed and hardened. Then, the crushed snow is introduced into the case and thrown away from a snow shooter with the impeller rotor.
