A plow attachment in accordance with the present disclosure includes a plow member and hook-shaped brackets. The plow member is an arcuate shaped member configured for moving or plowing loose material such as snow, slush, etc. The plow member is removably coupled to the snow blower by the hook-shaped brackets and fasteners. L-shaped angling members are provided on the plow member. The brackets and the L-shaped angling members are configured so that the angle of the plow member relative to the snow blower and the surface being plowed can be adjusted. ## Claims ### Claim 1 A plow attachment for a snow blower, the plow attachment comprising: an arcuate plow member having parallel top and bottom edges and parallel side edges extending therebetween, first and second openings formed between the top and bottom edges and spaced inward from the side edges; first and second hook-shaped brackets having integrally formed vertical and horizontal portions extending at a substantially right angle from one another, a first elongated slot formed in the vertical portion and a second elongated slot formed in the horizontal portion; first and second plow member fastening portions for removably fastening the first and second hook-shaped brackets to the plow member, the first and second plow member fastening portions being configured for insertion through the elongated slots in the vertical portions of the first and second hook-shaped bracket member and the opening formed in the plow member; and first and second snow blower fastening portions for removably coupling the first and second hook-shaped brackets to the snow blower, the first and second snow blower fastening portions being configured to be inserted through the elongated slots in the horizontal portions of the first and second hook-shaped bracket members and through openings formed in the snow blower. ### Claim 2 (depends on 1) The plow attachment of claim 1, further comprising: first and second L-shaped angling members mounted on a rear surface of the plow member, the first and second L-shaped fastening members having a wide portion and a narrow portion extending therefrom at a substantially right angle, the wide and narrow portions sharing a common side edge, the side edge configured to be in surface-to surface with the plow member and the wide portions configured to be substantially aligned with the side edges of the plow member. ### Claim 3 (depends on 2) The plow attachment of claim 2, further comprising: a through hole formed in the L-shaped angling member at the substantially right angle and a bolt extending therethrough for coupling the L-shaped angling member to the plow member, wherein the L-shaped angling member is rotatable about the bolt for adjusting the angle of the plow member. ### Claim 4 (depends on 1) The plow attachment of claim 1, wherein the first and second plow member fastening portions comprise first and second carriage bolts configured to be inserted through the elongated slots in the vertical portions of the hook-shaped bracket and the first and second openings formed in the plow member, and first and second knobs configured to be coupled to the first and second carriage bolts for fastening the first and second hook-shaped brackets to the plow member. ### Claim 5 (depends on 1) The plow attachment of claim 1, wherein the first and second snow blower fastening portions comprise first and second carriage bolts configured to be inserted through the elongated slot in the horizontal portion of the bracket and the openings in the snow blower, first and second knobs for securely fastening the hook-shaped brackets to the snow blower, and first and second rubber mounts, the first and second rubber mounts are configured to be sandwiched between the snow blower and the bracket. ### Claim 6 (depends on 1) The plow attachment of claim 1, further comprising a rubber member extending along the bottom edge of the plow member and extending towards a surface to be plowed. ### Claim 7 (depends on 1) The plow attachment of claim 1, wherein the vertical portion of the hook-shaped bracket member is an arcuate member and a rear convex surface of the plow member is configured to nest in the vertical portion when the plow member is coupled to the hook-shaped bracket. ### Claim 8 A snow blowing and plowing apparatus, the apparatus comprising: a snow blower having a housing containing a rotating spiral blade driven by an engine, the housing having an open front end defined by top peripheral edge and two side peripheral edges and having two openings formed in a top surface in proximity to the top peripheral edge; a plow attachment comprising an arcuate plow member having parallel top and bottom edges and parallel side edges extending therebetween, first and second openings formed between the top and bottom edges and spaced inward from the side edges and first and second hook-shaped brackets having integrally formed vertical and horizontal portions extending at a substantially right angle from one another, a first elongated slot formed in the vertical portion and a second elongated slot formed in the horizontal portion; first and second plow member fastening portions for removably fastening the first and second hook-shaped brackets to the plow member, the first and second plow member fastening portions being configured for insertion through the elongated slots in the vertical portions of the first and second hook-shaped bracket member and the opening formed in the plow member; and first and second snow blower fastening portions for removably coupling the first and second hook-shaped brackets to the snow blower, the first and second snow blower fastening portions being configured to be inserted through the elongated slots in the horizontal portions of the first and second hook-shaped bracket members and through the openings formed in the top surface of the snow blower housing. ### Claim 9 (depends on 8) The apparatus of claim 8, further comprising: first and second L-shaped angling members mounted on a rear surface of the plow member, the first and second L-shaped fastening members having a wide portion and a narrow portion extending therefrom at a substantially right angle, the wide and narrow portions sharing a common side edge, the side edge configured to be in surface-to surface with the plow member and the wide portions configured to be substantially aligned with the side edges of the plow member. ### Claim 10 (depends on 9) The apparatus of claim 9, further comprising: a through hole formed in the L-shaped angling member at the substantially right angle and a bolt extending therethrough for coupling the L-shaped angling member to the plow member, wherein the L-shaped angling member is rotatable about the bolt for adjusting the angle of the plow member. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the first and second plow member fastening portions comprise first and second carriage bolts configured to be inserted through the elongated slots in the vertical portions of the hook-shaped bracket and the first and second openings formed in the plow member, and first and second knobs configured to be coupled to the first and second carriage bolts for fastening the first and second hook-shaped brackets to the plow member. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the first and second snow blower fastening portions comprise first and second carriage bolts configured to be inserted through the elongated slot in the horizontal portion of the bracket and the openings in the snow blower, first and second knobs for securely fastening the hook-shaped brackets to the snow blower, and first and second rubber mounts, the first and second rubber mounts are configured to be sandwiched between the snow blower and the bracket. ### Claim 13 (depends on 8) The apparatus of claim 8, further comprising a rubber member extending along the bottom edge of the plow member and extending towards a surface to be plowed. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the vertical portion of the hook-shaped bracket member is an arcuate member and a rear convex surface of the plow member is configured to nest in the vertical portion when the plow member is coupled to the hook-shaped bracket. ### Claim 15 (depends on 8) The apparatus of claim 8, wherein the horizontal portion of the hook-shaped bracket member is an arcuate member and is configured to nest with an inner surface of the snow blower housing.
