A snow thrower includes a motor, an auger driven by the motor to rotate, a handle device for a user to operate, an auger housing for containing the auger and a frame for connecting the handle device and the auger housing. The auger housing is made of at least two different materials.

Disclosed herein is a device that is configured to melt at least one of snow and ice, comprising a coil formed from an elongated member having a first end and a second end, the elongated member having a surface comprising at least one of grooves, notches and pores configured to facilitate movement of liquid by capillary action. Corresponding methods and systems also are disclosed.

An Internet-based system for helping building management team members in significant ways: (i) predicting and forecasting when excessive snow load conditions present serious risks to a building's structure; (ii) receiving automatic notifications when snow load conditions are developing at specific regions on a building rooftop to warrant intervention and automated mitigation through the use of VR-guided snow removing robot systems; (iii) collecting various forms of intelligence about conditions developing on and about a building rooftop and storing such information with annotations for use in supporting intelligent decision making processes; (iv) quickly, efficiently and safely removing dangerous risk-presenting snow load conditions on a building rooftop while minimizing risk to human workers and increasing building operating efficiency; and (v) automatically removing excessive snow load conditions at specified regions on a building's rooftop.

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.

A method and system is disclosed which provides for a zero turn stand-on snow blower with only two powered wheels and two free wheeling casters which provides for the ability to blow snow from narrow paths, turn around without leaving the sidewalk, automatically turn off the auger and present a shovel for performing quick detailed shoveling tasks when stepping off the snow blower.

A gasoline powered walk behind snow removal device modified to include drive motors and a linear actuator controlled snow discharge chute to provide a remote controlled snow removal device. The modification includes a control unit mounted to the handle or frame structure to remotely control the snow removal device using a hand held wireless system. The drive includes a single piece mounting bracket or pair of mounting brackets fastened to the frame structure. The mounting brackets receive a pair of motor brackets and motors to drive a first drive wheel and a second drive wheel disposed on opposing sides of the frame structure.

A snow thrower includes a first drive shaft enabled to rotate about a first axis; an auger having auger blades mounted to the first drive shaft, a second drive shaft enabled to rotate about a second axis, an impeller having an impeller base mounted to the second drive shaft and impeller blades where the second axis and the first axis are perpendicular to each other, a walking wheel assembly, a first motor configured to drive the walking wheel assembly to rotate, a second motor configured to drive the auger to rotate about the first axis and drive the impeller to rotate about the second axis, a first reduction assembly including first-type gears for realizing power transmission between the second motor and the second drive shaft, and a second reduction assembly including second-type gears for realizing power transmission between the second drive shaft and the first drive shaft.

A bi-directional snow blower includes a frame coupled to a suspension mechanism of a motorized vehicle. A scraper blade may be rigidly and non-pivotally coupled to the frame, to move the scraper blade together with the frame and orient the scraper blade into a range of positions, including a raised position, a first lowered position and a second lowered position. The bi-directional snow blower may remove particulate from the floor surface when the vehicle is traveling in a forward direction and in a reverse direction opposite to the forward direction.

Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.
