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.

A three-stage snow thrower having a housing, a power supply, a longitudinal drive shaft extending from the power supply into the housing, and a lateral drive shaft extending between opposing side walls of the housing and being meshingly engaged with the longitudinal drive shaft within a gear assembly. The first stage assembly includes a plurality of augers attached to the lateral drive shaft for pushing loosened snow axially toward the gear assembly. The second stage assembly includes at least one auger attached to the longitudinal drive shaft for pushing snow from the first stage assembly axially rearward. The third stage assembly includes an impeller that rotates to throw the snow through a chute attached to the housing to expel the snow from the housing.

A nozzle for use with a walk-behind blower includes a nozzle restriction due to a sloped upper wall of the nozzle body. The nozzle restriction increases the air velocity in the upper region of the nozzle and forces leaves and debris downward so that airflow through the lower region of the nozzle more effectively laterally displaces them. The configuration of the nozzle body may be adapted to accommodate a variety of engine outputs while utilizing a common design for a blower frame, impeller and shroud.

Blower nozzle with variable velocity output

A combination blower assembly and string trimmer whereby the string trimmer head is easily detachable without the use of any tools. The device includes a blower assembly that further includes an upper and lower housing mated together to form a volute-shaped cavity where an impeller with airfoil-shaped blades reside. The detachable string trimmer head is located under the lower housing of the blower assembly and is easily attached or removed from the blower assembly by a simple push and turn motion. The blower assembly further includes an air inlet and air inlet cover. When the air inlet cover is rotated to a position where the air inlet is open the blower assembly is operable and the string trimmer is inoperable. Furthermore, when the air inlet cover is rotated to a position where the air inlet is closed the blower assembly is inoperable and the string trimmer is operable.
