A centrifugal snow blower having a frame, a fan rotatable about a central axis supported on the frame and a housing surrounding said fan having a peripheral wall defining at least an opening in direction of clearing and a duct extending tangentially for the ejection of snow. The housing is supported for rotative adjustment about the central axis by a central bearing journaling the housing to said frame, an annular guide member secured to the housing concentric with the central axis and at least one releasable braking device supported on the frame for cooperation with the guide member to fix said housing in selective rotative positions. |
