A rotary broom assembly is provided for use with a vehicle to reduce the accumulation of ice and snow on the rotary broom assembly when clearing paved surfaces, such as airport runways. The rotary broom assembly includes one or more wiper assemblies that are mounted for reciprocating movement along a broom hood. The broom hood includes a generally flat top surface and the wiper assemblies move along the top surface to clear snow and ice from the top surface of the broom hood. During forward movement of the wiper blade, the scraping edge of the wiper blade contacts the top surface of the broom hood to remove accumulated ice and snow. During the reverse movement of the wiper blade, the scraping edge of the wiper blade is lifted from the top surface to reduce removal of accumulated ice and snow during the reverse movement.

An automatic moving snow removal device including a moving module, driving a snow blower to move; a working module, including a working motor and a snow throwing mechanism driven by the working motor, the snow throwing mechanism is driven by the working motor to collect accumulated snow and inclusions on the ground and throw out of the snow throwing mechanism; and a control module, configured to control a rotary speed of the working motor to cause a speed when the inclusions depart from the snow throwing mechanism is not higher than 41 m/s.

A snow plow-blower operates as a snow plow, snow blower/thrower or as a snow plow-blower combination. The snow plow-blower includes a plow head blade and at least one blower door. The cavity contains a snow moving means, single, dual, or multi staged, for moving snow, ice and other materials out through at least one discharge chute and/or at least one opening. The blower door is adapted to move to a partially open configuration to expose the cavity, and from the partially open configuration to a partially closed configuration to thereby decrease snow, ice and other material ingress into the snow blower unit. Preferably, at least one retractable and extendable wing is located on the plow head blade to advantageously provide varying closed and open extended position configurations or positions for the removal of snow, ice or other material and debris.

A snow blower device having a housing forming a cavity configured to receive snow. A rotatable auger is supported by the housing and positioned within the cavity to gather and direct snow into a discharge chute having a lumen extending from the inside of the housing to the outside of the housing. The device further includes a blade combined with the frame and movable between a retracted position and an engaged position. In the retracted position the blade is positioned to let the snow reach the auger when the snow blower is moved in the forward direction. In the engaged position the blade is moved downward so that it contacts the ground surface and functions as a plow or snow push when the snow blower is moved in a backward direction.

The disclosure provides a power head and an outdoor power equipment using the same. The power head includes a housing assembly, a motor assembly and a battery pack assembly. The housing assembly includes a first housing and a second housing. The first housing and the second housing defines a housing space. The motor assembly is arranged in the housing space. The motor assembly includes a motor. One end of an output shaft of the motor extends to outside of the housing assembly. The battery pack assembly is arranged inside the housing space. The battery pack assembly supplies power for the motor assembly.

A snow removal system. The snow removal system includes a housing having an inlet disposed on a front side thereof, wherein the inlet is in fluid communication with a first chamber. An auger is disposed transversely across the first chamber, wherein the auger is operably connected to a motor within the housing. The auger rotates about a longitudinal axis thereof to mash snow and transport the mashed snow into a second chamber when the motor is actuated. The second chamber includes a primary heating element therein, the heating element designed to heat snow within the second chamber to produce steam. An outlet is disposed through a sidewall of the second chamber, wherein the outlet can emit steam from the second chamber.

Snow removal machines are provided that have an auger assembly for directing snow rearwards to be received by a discharge chute, and an auxiliary snow moving assembly for directing snow rearwards to be received by the discharge chute. The auger assembly has auger blade(s) coupled to an auger axle for rotation therewith about a first axis defined by the auger axle. The auxiliary snow moving assembly has snow moving member(s) coupled to an auxiliary axle for rotation therewith about a second axis defined by the auxiliary axle. The auxiliary axle is lower and rearwards of the auger axle towards the discharge chute; and an auxiliary drive assembly is configured to rotationally couple the auxiliary axle to the auger axle such that rotation of the auxiliary axle is driven by rotation of the auger axle.

A working machine is provided, which can suppress reduction in visibility of a spot illuminated by illuminating light even when an ambient light environment changes. A working machine in which a working unit that performs predetermined work is connected to a machine body that travels is configured to include a headlight that illuminates a traveling direction of the machine body and is capable of color adjustment, a camera that detects a color of an illumination spot P that is illuminated by illuminating light K of the headlight, and a control unit that performs color adjustment of the headlight in accordance with the color detected by the camera.

A snow thrower is disclosed including a rotor assembly having a first auger, a second auger, and a paddle disposed between the first and second augers The snow thrower also includes an intake housing having a first interior surface adjacent to the first auger and a second interior surface adjacent to the second auger, where an outer edge of the first auger has a clearance of less than 1 centimeter from the first interior surface across a sweep of at least 120 degrees, and an outer edge of the second auger has a clearance of less than 1 centimeter from the second interior surface across a sweep of at least 120 degrees.
