An autonomous snowbank deconstructing system includes an autonomous vehicle, one or more boom arms coupled to the autonomous vehicle, and a dulled shovel component coupled to the one or more boom arms. The autonomous vehicle is configured to autonomously gather loose debris to form one or more debris piles with repetitive, low-impact contact of the dulled shovel component with the loose debris, and autonomously deconstruct accumulated debris with repetitive, low-impact contact of the dulled shovel component with the accumulated debris.

A snow removal system includes a work machine and a snow removal machine. The work machine includes a work unit configured to perform work and a position detector configured to detect a position of the work machine when the work unit has performed the work and generate position information indicating the detected position. The snow removal machine is capable of autonomous movement and includes a snow removal unit configured to perform snow removal work and a controller configured to cause the snow removal unit to perform the snow removal work on the basis of the position information.

An array of retractable shields is employed for closing an exposed opening through which the snow enters into a receiver. A piston-like object, which is empowered by a compressed spring and is moving at high speed, makes an impact on the snow with great force. The snow is finally ejected from a chute. The receiver can be lifted higher to clear the snow at a different height from the ground. Alternatively, a snow lifting unit is used to ferry the snow higher for free fall into the receiver for further processing. Belt and chain driven devices employing a plurality of collector elements are employed. An impact force produced by a rapid flow of compressed air also forces the snow out from a confined enclosure.

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 lawn mower or stand-on powered drivable machine has an electrical port that receives current from an alternator powered by the engine or motor. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric (TEC) elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.

A lawn mower has an electrical port that receives current from an alternator powered by the lawn mower engine. The current and voltage sent the electrical port depend on a flywheel and stator arrangement operatively connected to the alternator. The stator may be replaceable or interchangeable to selectively determine the alternator current and voltage output. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.

A sweeping machine for mounting to a blower is adapted for sweeping debris, e.g., snow, from an area around an obstacle, e.g., fire hydrant. The sweeping machine comprises a rotating brush having an axis of rotation which is horizontal, a frame for the rotating brush, an arm extending from a proximal end to a distal end to which the frame is secured, a blower, and a pivoting mechanism secured to the blower. The pivoting mechanism is adapted to swivel the arm upwardly to lift the rotating brush and to swivel the arm within a horizontal plane to move the rotating brush horizontally relative to the blower. Thereby, the sweeping machine is adapted to sweep debris from the area around the obstacle by the rotating brush toward the blower which is itself adapted to blow the debris away from the obstacle.
