A powered device may include an engine, a mobility assembly operably coupled to the engine to provide mobility of the powered device responsive at least in part to operation of the engine, a working assembly operably coupled to the engine to perform a working function responsive at least in part to operation of the engine, and a key-operated combination ignition and speed control assembly including switch circuitry configured to control both starting the engine and selection of different selectable positions corresponding to respective different operating speeds for the engine.

A snow removal device may include a chassis supporting a power unit, a mobility assembly operably coupled to the chassis to provide mobility for the snow removal device responsive to power provision from the power unit, a working assembly configured to move snow to an ejection path responsive to power provision from the power unit, and a chute assembly forming a portion of the ejection path, the chute assembly comprising a chute and a deflector. The chute may be rotatable via a chute rotator configured to provide at least 360 degree automated rotation of the chute. An orientation of the deflector may be changeable via automated pivoting of the deflector via an electrically operable deflector adjuster.

A snow blower including an auger housing, an auger rotatably positioned within the auger housing and configured to blow snow, a shaft attached to the auger and the auger housing, a chute attached to the auger housing and configured to direct the snow blown by the auger away from the snow blower, and at least one sensor configured to detect at least one of a rotational speed of the auger or the shaft and a load, torque, and/or thrust on the shaft or the auger housing. The data collected by the at least one sensor is used to determine an instantaneous flow rate of snow.

A handheld snow removing system includes an intake scoop with a rotating intake auger, a discharge chute configured to direct a flow of material to a point outside of the handheld snow removing system, a fan chamber disposed between the intake scoop and the discharge chute, and an energy-conversion device configured to drive elements of the fan chamber and the rotating intake auger. The fan chamber includes a fan configured to create a suction force within the fan chamber to create the flow of material from the intake scoop, through the fan chamber, and out through the discharge chute.

The present pull-type snow blower attachment comprises a housing, a auger and a snow blowing fan arrangement. The housing defines a longitudinally curved surface between two walls. A hitch protrudes away from the surface and is adapted for attachment behind a vehicle. The auger is rotatably secured to the walls of the housing. The auger defines two opposite sections and a middle section therebetween. Each opposite section is equipped with a spiral blade angled towards the middle section, and the middle section is equipped with at least two blades for lifting snow. The snow blowing fan arrangement includes a fan and a chute section above the fan. The fan is between the auger and the hitch. The fan is adapted for receiving snow lifted by the at least two blades of the auger and pushing the snow through the chute section.

Disclosed is a snow shoveling and snow discharging assembly of a snow sweeping robot. The snow shoveling and snow discharging assembly comprises a snow stirring structure, a snow feeding structure and a snow raising structure. Stirring cutters in the snow stirring mechanism are driven by a stirring cutter shaft to stir bottom area snow into a snow feeding pipe of the snow feeding structure, an air blower in the snow feeding structure blows accumulated snow into a snow raising pipe of the snow raising structure through a connecting pipe, the snow raising pipe can be driven by a steering motor to rotate by a certain angle to control the snow raising direction, and a second electric push rod acts to control pitching of the guide part, so that the height of snow during snow raising is controlled.

A power tool includes a power a motor, a driver circuit, a capacitor, a capacitor switch, a temperature detection unit, and a controller. The capacitor is configured to filter out current spikes in a power supply. The capacitor switch is configured to control a working state of the capacitor. The temperature detection unit is configured to detect a temperature of a related object. The controller is configured to: acquire the temperature of the related object; control the capacitor switch to be in a first on or off state such that the capacitor works in a first working state when the temperature is lower than a temperature threshold; and control the capacitor switch to be in a second on or off state such that the capacitor works in a second working state when the temperature is higher than the temperature threshold.

A system that is towed behind a vehicle to remove snow and ice from pavement. The system includes a trailer. The trailer includes a longitudinal substantially rigid frame structure, a trailer hitch connected to a front end of the trailer for selective connection-disconnection to the vehicle, and a suspension appliance connected to a rear portion of the trailer to separate at least a rear portion of the frame structure from the pavement. At least two additive snow and ice removal tools are connected to the frame structure and located underneath the trailer and over the pavement, each of the tools enabling a different type of snow and ice removal from the pavement when towing the system behind the vehicle to remove snow and ice from the pavement.

A brush retrofit for mounting behind a snow plow blade of a snow removal vehicle is disclosed. The brush retrofit includes a base frame, a stationary brush assembly, a retrofit mount, a brush elevation actuator, and a retrofit mount. The stationary brush assembly is movably mounted to the base frame. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade. The brush elevation actuator when activated, moves the stationary brush assembly relative to the base frame between a raised storage position and a lowered in-use position. The retrofit mount is configured to secure the base frame to a support structure of the snow removal vehicle behind the snow plow blade.

A chute control assembly for a snow thrower having a housing, handle, and a chute includes a control mechanism, a connecting mechanism, and a guide mechanism. The control mechanism includes an actuator mechanism that allows an operator to manually control the orientation of the chute from a position spaced apart from the chute. The connecting mechanism transfers rotation of the actuator mechanism to the guide mechanism. The guide mechanism is attached to the chute and rotates and adjust the orientation of the chute in response to rotation of the actuator mechanism in order to change the direction that snow is thrown from the snow thrower.
