     No efficient mechanical process currently exists to remove snow or other debris that may accumulate on the parking surfaces under semi-trailers or other cantilevered structures. Current methods for removing snow from under semi-trailers include extra wide plows that leave windows under the trailers making it even more difficult for semi-tractors to hook up correctly. (Not shown) Offset box blades on skid steers or tractors allow for minimal snow capacity to be moved and significantly increase the amount of machine maneuvering and operator error. (Not shown) For example, operators must continually remove the box blade from underneath the trailers once the box blade is full of snow (approximately every 30-50′ depending on the snow fall amount). Large/fixed angle plows with an offset mount are also currently used and present the same difficulties as a box plow, as previously discussed. (Not shown) The method of clearing snow or debris with large/fixed angle plows offers even less snow carrying capacity and requires the operator to essentially make repeated “swoops” or “passes” under the semi-trailers increasing the possibility of accidents and property damage. 
     The following detailed description is of the best currently contemplated modes of carrying out illustrative embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appending claims. Various inventive features are described below herein that can each be used independently of one another or in combination with other features. 
       FIG. 1  provides a simplified side view of an illustrative embodiment of the cantilevered debris plow of the present disclosure. As shown, the cantilevered debris plow  10  is attached to a skid steer loader  2  having loader arms  3  via a skid steer loader universal quick attach plate (attachment plate)  5  secured to the housing  12 . Attachment plate  5  is constructed such that the loader side  5   a  is can be detached or attached via the pins as typically found at the end of loader arms  3   a . On the attachment or accessory side, the plate  5   b  is typically secured attached to the attachment or accessory and allows quick attaching or coupling with the loader side  5   a  by pushing the plate  5   a  up and into the (“scooping up”) the attachment or accessory. This type of quick tach type plate and set-up as shown here are well known to one of ordinary skill and typically designed to fit any model of skid steer loader or tractor having a loader mounted therein including models built by Bobcat, Case, ASV, Gehl, John Deere, New Holland and/or Caterpillar. One of ordinary skill will appreciate that housing  12  may be attached to the loader arms  3  in a multitude of ways other than with attachment plate  5  including by pins, rods and hitches and or combinations therein without departure from the spirit and intent of the present disclosure. 
       FIG. 2  is a front view of an illustrative embodiment of the cantilevered debris plow illustrating its asymmetric nature i.e. attachment plate  5  is not attached to the housing  12  at its middle or center.  FIG. 3  is a view provided for perspective combing  FIGS. 1 and 2  illustrating the illustrative embodiment positioned with a canti-levered semi-trailer  6  according to the present disclosure.  FIG. 3A  is a detailed front view of the illustrative embodiment according to  FIG. 3  and further providing relative dimensions useful in understanding the problem solved by the present disclosure. As shown throughout, the housing  12  of the cantilevered debris plow  11  (“hereinafter referred to exclusively as “plow”) has a total length of 15.71 feet and is defined as having a debris inlet end  11   a  and debris outlet end  11   b . The debris inlet end  11   a  extends a considerable distance away from the prime mover  2  and is distal to the prime mover  2 . A skidshoe  24  is affixed to the frame of the plow  11  on the underside to support the distal end at the end plate  27 . (See also  FIGS. 4, 5 and 6 ) Additionally an adjustable jack  33  attached via the jack mount  35  allows for adjustment of the tension placed upon the skidshoe  24  during operation as more or less weight can be placed on skidshoe  24  by raising or lowering the jack  33  and engagement of the caster wheel  36  with surface  1 . During transit, the adjustable jack  33  may be fully lowered thereby raising skidshoe  24  off the surface  1  allowing for raised transit without engagement with surface  1 . Those of ordinary skill will appreciate that the loader arms  3  may be raised or lowered as well for operation or transit of plow  11 . (Not shown) Additionally, although not shown, one of ordinary skill will understand that the manual adjustable jack  33  herein may be replaced with a hydraulically actuated version without departure from the spirit and intent of the present disclosure. To assist with clearing operations and operator guidance a light  37  may be positioned on the housing  12  at either or both ends of the housing. 
     As shown in  FIGS. 3 and 3A , a semi-trailer  6  is an example of a cantilevered structure having at least one axle  7  is positioned at the rear of the trailer while the dolly of the trailer  10  supports the front end of the semi-trailer leaving a certain amount of the semi-trailer supported by the trailer dolly and hanging over the trailer dolly. This presents a problem because semi-tractors or other prime movers (not shown) are unable to be properly hitched to the semi-trailer  6  due to the accumulated snow or other debris interfering with proper placement of the semi-tractor under the trailer and for connection with the trailer hitch. (Not shown) Often times this leads to semi trailers  6  becoming disconnected and falling to the ground causing damage and even injury. Further, as illustrated in  FIG. 13 , the large scale of the modern parking lot surrounding a warehouse and the typical higher costs of labor, a solution is needed does not require manual labor for removal of accumulated debris under this particularly hard to reach surfaces. 
     The area of the parking surface covered by the cantilevered trailer  6  is defined by the width of the trailer in a first dimension and the distance from the front of the trailer to the trailer dolly  10  of the trailer  6  in a second dimension. Typically, the trailer hitch  9  is positioned between the front of the semi-trailer and the trailer dolly  10 . A third dimension is the distance from the parking surface to the bottom of the trailer which is heretofore defined as the trailer clearance (height). One of ordinary skill will further appreciate from the present disclosure and figures that this third dimension also increases the difficulty and cost of solving this problem. 
     As shown the housing  12  on the first end extends between 1-2 feet past the outer width of the skid steer (prime mover) as illustrated by outer wheel  4   b  creating an outer end section  13  having an outer end dimension  13   a  of approximately five (5) feet from the center of the attachment plate  5 . The housing  12  on the debris inlet end  11   a  extends past the inner wheel  4   a  in the range of 8-10 feet creating an inner end section  14  having an inner end section dimension  14   a  of 10-11 feet. Further, as shown, the plow  11  is constructed with a housing height dimension of two (2) feet allowing a clearance of almost two (2) feet under the cantilevered portion of the trailer defined as the portion between the front of the trailer and the trailer dolly. As the dimensions of the trailer frame  6   b  height and the distance the trailer hitch  9  hangs down may vary, this is considered to be a reasonable clearance but is only one of many clearances which may be suitable for a particular application. One of ordinary skill will appreciate that the combination of the longer inner section  14  and the low profile of the plow  11  allows it to reach under the front portion of the trailer to remove accumulated debris positioned therein. One of ordinary skill will appreciate that other dimension combinations are possible that are suitable, dependent upon the particular application, for removal of accumulated debris from a parking surface  1   a  under a cantilevered trailer  6 . 
       FIGS. 4-12  illustrate and enable one embodiment of a plow  11  having an augur  40  positioned therein that may be engaged with a skid steer or other prime mover  2 . As discussed infra, a portion of the plow  11  may be positioned under an end of a semi-trailer or other cantilevered structure, as shown in  FIGS. 2-3 and 13 . 
       FIG. 4  provides a front perspective view of the plow  11  showing the offset in lengths between the inlet and discharge ends of the plow attached to a prime mover (shown as as a skid steer  2 ) previously discussed. As one of ordinary skill will appreciate that debris inlet side loader wheel ( 4   a ) of the skid steer may be replaced or substituted with tracks without limitation or restriction, as suitable for the particular application and or conditions. 
     As best illustrated by  FIGS. 4, 5, 6 and 7 , the housing  12  of the plow  11  is constructed of steel in the exemplary models shown. The housing  12  is compromised of a frame  20  illustrated as a “straightened” curved shape (see end view  FIG. 6 ) having both vertical  21  and horizontal braces  22  supporting the augur  40  positioned therein. As previously discussed, an attachment (mounting) plate  5   b  is affixed to the frame  20  with additional bracing on either side of the mounting plate  5   b  to enhance structural rigidity necessary support the cantilevered design. The plow  11  and various elements thereof may be constructed of any material known to those skilled in the art that is appropriate for the specific application thereof. For example, steel, metallic alloys, synthetic materials, natural materials, combinations thereof, and/or any other suitable material may be used without limitation. Although not shown, one of ordinary skill will appreciate that the mounting plate may be affixed to the housing and supporting frame by any number of methods includes by welding or by use of typical fasteners well known to those of ordinary skill in the art. In other embodiments, not shown, additional horizontal and or vertical rails may be affixed to the housing. Saddles that cooperatively engage with the rails may then be affixed to the mounting plate  5   b . The horizontal and or vertical rails in combination with attachment of additional hydraulic cylinders would then allow further adjustment of the vertical and or horizontal position of the plow  11  in relation to the prime mover  2 . For example, the addition of horizontal rails and a hydraulic cylinder may allow the operator to advance or retract the debris inlet end in relation to the prime mover increasing utility in reaching further under trailers or easy entry into and through parking lot gates. 
     As shown in  FIGS. 5 and 12 , the debris inlet end  11   a  is closed or solid. As shown, the hydraulic pump  30  and its drive components (drive shaft  42 , drive sprocket  43 , drive chain  44 ) are positioned at debris inlet end  11   a . Hydraulic lines  31  and hydraulic pump  30  sit on the rear side of the housing and are affixed to the housing therein and protected by pump enclosure  32 , which is removable as needed for maintenance or replacement of hydraulic lines  31  and hydraulic pump  30 , as needed. Hydraulic pump  30  and its drive components are integrated into housing  12  and frame  20 . As the plow  11  shown is subject to severe loads caused by engaging and driving through snow and ice, the drive components for the plow  11  are secured within and protected by drive end enclosure  25  having external protection plate  26 . Drive chain  44  is coupled to the auger sprocket  41  affixed to auger shaft  40   a  to rotatably drive the auger  40  having auger flighting  40   b  for contact and engagement with debris to be removed when energized by the hydraulic system and pump  30 . The auger  40  is secured within housing  12  with its auger shaft  40   a  supported by a combination of bearings secured within frame  20  of housing  12 . At the debris inlet side, the auger  40  is secured within the housing by flange bearing  29  affixed to the interior of end plate  27  and auger shaft  40   a  positioned therein. The auger  40  as shown has a diameter of 11.25 inches. One of ordinary skill will appreciate that other dimensions are possible without departure from the spirit and intent of the present disclosure. 
       FIG. 11  provides a detailed view of the front side of the debris inlet side of the plow  11  with protection plate  26  in plate. As shown in the top of  FIG. 12 , the pump  30  is affixed to and positioned on the back side of the plow  11  with the drive chain  44 , auger sprocket  41  affixed to auger shaft  40   a  and flange bearing  29  secured behind the protection plate  26 . One of ordinary skill will appreciate that other drive configurations are possible without departure from the spirit and intent of the present disclosure. 
       FIG. 6  provides a cross-sectional view of the debris outlet end of the plow  11  disclosed herein and  FIG. 7  provides a perspective view of the plow  11  from the debris outlet end  11   b  disclosed herein unattached to primary mover  2 . As shown, the debris outlet end  11   b  is open. As best illustrated by  FIG. 6 , auger  40  and auger shaft  40   a  are secured and supported within housing  12  at debris outlet end  11   b  by a number of hanger bearing assemblies  46  affixed to the frame  20  of housing  11  by a number of hanger bearing assembly bolts  46   a , as shown. A hanger bearing  47  is positioned within each hanger bearing assembly  46 , with auger shaft  40   a  positioned in and through the hanging bearing  47 . This particular combination of structure (hanger bearings  46 /hanger bearing assembly  47 ) allows the debris outlet end  11   a  to have an open configuration. One of ordinary skill will appreciate that other bearing and bearing support configurations are possible without departure from the spirit and intent of the present disclosure. 
     As best shown by  FIGS. 4, 7 and 8 , the plow  11  may be configured so that the skid steer or other prime mover  2  to receive energy from the prime mover via a power take off, compressed fluid source, or any other energy source without limitation (e.g., pneumatic, electrical, etc.) to power the debris moving system of the plow  11 , shown through-out as an auger without limitation. Although not shown, one of ordinary skill will appreciate that other types of powered debris moving systems could be used with the present apparatus and method including without limitation or restriction powered system having bristles or brushes allowing for removal of accumulated debris including trash, dirt, dust, fines, and or snow, as suitable for the particular application. As shown throughout in the following figures, applicant has chosen a prime mover  2  having a hydraulic system (not shown) using typical hydraulic lines  31  and a hydraulic pump (aka drive motor)  30  to power rotation of the auger  40  allowing for engagement and removal of accumulated snow from the surfaces engaged.
