A multiple-stage snow thrower having a housing, a power supply operatively connected to a plurality of drive shafts for rotating a plurality of stage assemblies. Each stage assembly of the multiple-stage snow thrower is configured to move snow either axially along the axis of rotation or radially away from the axis of rotation. The first stage assembly is configured to expel snow from the housing, thereby throwing the snow away from the snow thrower. The second, third, and fourth stages assemblies are configured to push the snow toward the longitudinal centerline of the housing and then rearwardly toward the first stage assembly.

A snow grooming vehicle comprising a support frame; an engine; two tracks mounted on opposite sides of the support frame itself, coupled to and driven by the engine; and comprising a first plurality of bristles arranged in a portion of the snow grooming vehicle adjacent to the track so as to capture the snow collected on the track.

A snow shovel head, comprising an impeller rotately connected to an axle in a casing, a discharge chute and a chute handle, the casing comprising a back wall, a circumferential wall with an output to the chute, and a cut out bottom wall extending laterally from the back wall of the casing to the front opposite lateral corners of the bottom wall at the circumferential wall of the casing, and centrally from the back wall of the casing to the open front of the casing up to a tip recessed from said lateral corners; and the back wall extending to the lateral corners of the bottom wall at the circumferential wall; the impeller, when rotating, scooping up snow from the open front of the casing to an inner lateral surface of the circumferential wall of the casing towards the output to the chute for discharge of the snow.

A three-stage snow thrower having a housing, a power supply operatively connected to said housing, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending rotatably attached to opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The power supply drives the longitudinal drive shaft, thereby causing the longitudinal drive shaft to rotate, and at least a portion of such rotation is transferred to the lateral drive via a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft, wherein the first stage assembly pushes loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft, wherein the second stage assembly pushes the snow from the first stage assembly axially rearward in a transverse manner relative to the first stage assembly. The third stage assembly includes an impeller that rotates to throw the snow from the second stage assembly through a chute attached to the housing to expel the snow from the housing.
