A clearing vehicle comprises a supporting frame (3) and a sweeper-blower arrangement (4), which is adjustably pivotable around a vertical axis (5) which runs through the clearing vehicle with respect to the supporting frame (3) and comprises a blow-air device (8). Furthermore, a blower (6) is arranged at the supporting frame (3), wherein blow-air is conducted from the blower (6) through the hollow body (7) to the blow-air device (8). The hollow body (7) and the blow-air device (8) are brought in blow-air connection by a first pivoting movement from a transport position to a working position. The blow-air connection between the hollow body (7) and the blow-air device (8) is removed by a second pivoting movement from the working position to the transport position.

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.

An assembly for releasable attachment to a vehicle. The assembly comprises a frame including a mounting member configured to be mounted onto the vehicle, a plow blade mounted to the frame and a power broom coupled to the frame and disposed between the mounting member and the plow blade. The power broom is configured to be disposed in front of a most forward wheel of the vehicle relative to a forward direction of travel of the vehicle. The power broom is also configured to rotate to sweep snow away from the power broom.

A method of clearing debris from under a parked trailer comprising: a) engaging, with a cantilevered debris mover, a surface having debris accumulated thereon and positioned under at least one parked trailer having at least a front portion which is cantilevered; and b) removing said debris accumulated upon said surface under said at least one parked trailer to a surface not located under said at least one trailer; wherein said cantilevered debris mover further comprises: i) a powered mobile prime mover capable of providing a source of power to an accessory; and ii) an accessory configured as a cantilevered debris plow further comprising: 1) a closed end allowing intake of debris; 2) an open end allowing discharge of debris; 3) a mounting plate for attachment to said prime mover; and 4) a powered debris engager configured to accept power from said powered mobile prime mover.

This invention relates to the art of removing snow from driveways, walkways, roads, and the like. The snow removing system removes snow from the driveway and disposes it. The system can be operated by a person or by a computer program or by remote controller. The system comprises of components that are relatively small that can be easily assembled and stowed away after use. The system is easy use and does not require manual labor other than an easy setup and dismantle operations.

An attachment (60) for a wheeled work vehicle (2) for clearing snow comprises a support housing (3) which rotatably carries an elongated cylindrical brush (5) and a plough blade (4), with the plough blade (4) and the brush (5) alternately operable between a lower operative state and an upper inoperative state. End elements (62) are pivotally coupled about vertical pivot axes adjacent respective opposite ends (15,16) of the plough blade (4). The end elements (62) are pivotal about a main vertical pivot axis (64) between a plurality of forward and rearward states through respective outward states. A coupling mechanism (7) couples the attachment (1) to the wheeled work vehicle (2) so that the support housing (3) is slewable between a transverse state and respective maximum offset states. When the housing (3) is in the transverse state with the plough blade (4) in the transverse state, the end elements (62) may be configured in a plurality of working states relative to the plough blade (4), for example, with the end elements (62) in respective first forward states, in respective first rearward states and with one of the end elements in an outward state and the other in a first forward or a first rearward state. When the support element (3) is in one of the offset states with the plough blade (4) in a corresponding offset angled state relative to the transverse state, the end elements (62) are operable in a plurality of working states including second forward and rearward states with the end elements extending either forwardly or rearwardly relative to the plough blade (4) and parallel to the direction of normal forward motion of the wheeled work vehicle (2) or in respective outward states extending outwardly and substantially aligned with the plough blade (4).

Snow-clearing vehicle (1), having a sweeper-blower arrangement (10), wherein the sweeper-blower arrangement is adjustably pivotable around a vertical axis (13) which runs through the snow-clearing vehicle. The sweeper-blower arrangement has a sweeping-roller brush (4) which is rotatingly drivable around its longitudinal axis. In the direction of travel, blow-air openings (5, 6, 7, 8) arranged on both sides of the vertical axis are provided in front and along the sweeping-roller brush (4), which are arranged for simultaneous and identically acting blowing. This allows for an improved removal of the snow to be cleared.

A snow and ice clearing vehicle. The vehicle provides a combination of systems configured to facilitate the clearance and removal of snow and ice from roadways and sidewalks. The vehicle includes a snow clearing device, a heating system, and a suction system in communication with a reservoir. The snow clearing device is positioned on the front of the vehicle, wherein the heating system is positioned posterior to the snow clearing device and configured to apply heat to snow and ice not completely cleared by same. The suction system is positioned posterior to the heating system and configured to vacuum snow melted and loosened by the heating system. The reservoir is configured to retain water and snow captured by the suction system. The vehicle further includes a pump, wherein the pump is configured to remove the water from the reservoir through an outlet to an area remote from the vehicle.

An autonomous path treatment system and associated path treatment method uses a mobile path recording device having a locator, a processor and firmware to capture a sequence of coordinates and directions of travel of a path as the mobile device is moved along the path and generate a path program file. The system also has an autonomous path treatment robot having: a treatment mechanism for treating the path; a controller having a processor and memory storing firmware that when executed obeys steps of the path program file to control the motor and the treatment mechanism to treat the path; and a server configured to execute a path program to process the captured sequence of coordinates and directions into the path program file containing instructions for controlling the autonomous path treatment robot to treat the path based upon the coordinates.
