The specification discloses an improved rotary snow thrower. The thrower includes a saucer-shaped rotary member having a plurality of blade assemblies on its surface. Snow on the road surface is collected by a mould-board and is delivered to the saucer-shaped rotary member solely by gravity, so that the rotary member provides a constant centrifugal force for throwing the snow away from the thrower. The blade assembly is deflectable when it encounters the free-falling snow from the mould-board to the rotary member. The deflection provides a vibration for shaking any wet snow off the blade such that no snow may freeze on the blade to hamper the operation of the snow thrower.
