1. A vehicle pulled snow scraper system comprising:
a snow scraper assembly comprising;
a center scraper portion having;
a hitch receiver bar comprising;
a stationary tube having a first end and a second end; anda slide tube having a third end and a fourth end;an impact spring;a left support attacher;a right support attacher; anda blade pivot stop;a left stabilizer bar;a right stabilizer bar;a left vertical brace;a right vertical brace; anda main vertical brace having a top end and a bottom end;an upper horizontal receiver;a lower horizontal receiver; anda center blade portion;a left scraper portion having;
an left-upper adjustable bar;a left-lower adjustable bar; anda left blade portion;a right scraper portion having;
a right-upper adjustable bar;a right-lower adjustable bar; anda right blade portion; wherein said snow scraper assembly comprising said center scraper portion with said hitch receiver bar, said left scraper portion, and said right scraper portion in combination are operatively functional as an adjustable angle and an adjustable width vehicle pulled snow scraper; wherein said center scraper portion is removably coupled to a receiver tube of a trailer receiver hitch of a vehicle via said first end of said stationary tube of said hitch receiver bar; wherein said third end of said slide tube nestably slides into said second end of said stationary tube, said impact spring located within said stationary tube contacting said third end of said slide tube and an inner surface of said second end of said stationary tube; wherein said blade pivot stop is non-removably attached to a bottom side of said slide tube, said blade pivot stop limiting a blade backward rotation angle; wherein said left support attacher is non-removably attached to a left vertical side of said hitch receiver bar and said right support attacher is non-removably attached to a right vertical side of said hitch receiver bar to provide a coupling point for said left stabilizer bar and said right stabilizer bar; wherein said hitch receiver bar is pivotally attached to said main vertical brace, said hitch receiver bar positioned horizontally and coplanar with a longitudinal centerline of said receiver tube of said trailer receiver hitch of said vehicle; wherein said top end of said main vertical brace perpendicularly and non-removably joins about a midpoint of said upper horizontal receiver, and said bottom end of said main vertical brace non-removably joins about a midpoint of said lower horizontal receiver such that said main vertical brace, said upper horizontal receiver, and said lower horizontal receiver form a horizontal H-shape; wherein said left vertical brace and said right vertical brace are non-removably attached to and between said upper horizontal receiver and said lower horizontal receiver such that said left vertical brace and said right vertical brace are planar with said main vertical brace; wherein said left stabilizer bar is hingedly attached to said left support attacher of said hitch receiver bar and to said left vertical brace, said left stabilizer bar structured and arranged such that a length of said left stabilizer bar is adjustable; wherein said right stabilizer bar is hingedly attached to said right support attacher of said hitch receiver bar and to said right vertical brace, said right stabilizer bar structured and arranged such that a right-length of said right stabilizer bar is adjustable; wherein said center blade portion is removably fastened to an outer-back side of said center scraper portion; wherein said left-upper adjustable bar and said left-lower adjustable bar of said left scraper portion nestably slide within a left end of said upper horizontal receiver and said lower horizontal receiver respectively, said left-upper adjustable bar and said left-lower adjustable bar lockably adjustable via a plurality of through holes and a lock pin; wherein said left blade portion is removably fastened to a rearmost side of said left-upper adjustable bar and said left-lower adjustable bar; wherein said right-upper adjustable bar and said right-lower adjustable bar of said right scraper portion nestably slide within a right end of said upper horizontal receiver and said lower horizontal receiver respectively, said right-upper adjustable bar and said right-lower adjustable bar lockably adjustable via a plurality of through orifices and adjustment pins; wherein said right blade portion is removably fastened to a back side of said right-upper adjustable bar and said right-lower adjustable bar; and wherein said snow scraper assembly is useful for plowing snow from a ground surface using a motor vehicle, said angle and said width of said snow scraper assembly user-adjustable to determine a weight of a windrow of said snow accumulated via a movement of said snow scraper assembly across said snow. |
