The support structure includes a vehicle end and an attaching end, with the vehicle end attached to the mounting structure via a cushioning assembly. The accessory or plow is pivotally attached at the attaching end of the support structure and is pivotable about a generally vertical axis. The cushioning assembly includes (i) a first element attached at the vehicle end of the support structure, (ii) a second element attached at the mounting structure, and (iii) a plurality of resilient elements disposed between the first element and the second element. ## Claims ### Claim 1 A plow assembly for mounting at a vehicle, said plow assembly comprising: a mounting structure configured to mount at a vehicle; a support structure comprising a vehicle end and an attaching end, wherein said vehicle end is attached to said mounting structure via a cushioning assembly; a plow pivotally attached at said attaching end of said support structure and pivotable about a generally vertical axis; and wherein said cushioning assembly comprises (i) a first element attached at said vehicle end of said support structure, (ii) a second element attached at said mounting structure, and (iii) a plurality of resilient elements disposed between said first element and said second element. ### Claim 2 (depends on 1) The plow assembly of claim 1, wherein said mounting structure is configured to adjustably mount at the vehicle so as to be adjustable about a horizontal pivot axis relative to the vehicle. ### Claim 3 (depends on 2) The plow assembly of claim 2, wherein said first element comprises a non-circular receiver fixedly attached at said vehicle end of said support structure, and wherein said second element comprises a non-circular beam that is received within said receiver and that engages said plurality of resilient elements. ### Claim 4 (depends on 3) The plow assembly of claim 3, wherein said receiver comprises a square cross section shape and wherein said beam comprises a square cross section shape. ### Claim 5 (depends on 3) The plow assembly of claim 3, wherein said plurality of resilient elements comprise elongated resilient elements disposed at least partially along said receiver at corner regions of said receiver. ### Claim 6 (depends on 3) The plow assembly of claim 3, wherein each of said resilient elements comprises an elastomeric material that is compressible and biased towards its initial form. ### Claim 7 (depends on 3) The plow assembly of claim 3, wherein said beam is movably attached at said mounting structure. ### Claim 8 (depends on 7) The plow assembly of claim 7, wherein opposite end regions of said beam are received through a slot of a respective bracket of said mounting structure. ### Claim 9 (depends on 8) The plow assembly of claim 8, wherein said slot of said bracket comprises an elongated slot that allows for movement of said beam relative to said mounting structure in a first direction and limits movement of said beam relative to said mounting structure in a second direction orthogonal to said first direction. ### Claim 10 (depends on 9) The plow assembly of claim 9, wherein each of said elongated slots allows for movement of the respective end of said beam at that slot relative to the other end of said beam to allow for oscillation of said plow. ### Claim 11 (depends on 3) The plow assembly of claim 3, wherein, responsive to pivotal movement of said mounting structure about said horizontal pivot axis, said beam pivots within said receiver. ### Claim 12 (depends on 11) The plow assembly of claim 11, wherein opposite end regions of said beam are received through a slot of a respective bracket of said mounting structure, and wherein said slot of said bracket comprises an elongated slot that allows for movement of said beam relative to said mounting structure in a first direction and limits movement of said beam relative to said mounting structure in a second direction orthogonal to said first direction. ### Claim 13 (depends on 12) The plow assembly of claim 12, wherein, responsive to pivotal movement of said mounting structure to lower said plow, said beam moves upward along said slots and rotates about a horizontal axis within said receiver in a first direction. ### Claim 14 (depends on 13) The plow assembly of claim 13, wherein, responsive to pivotal movement of said mounting structure to raise said plow, said beam moves downward along said slots and rotates about said horizontal axis within said receiver in a second direction opposite said first direction. ### Claim 15 (depends on 1) The plow assembly of claim 1, wherein each of said resilient elements comprises an elastomeric material that is compressible and biased towards its initial form. ### Claim 16 An accessory assembly for mounting at a vehicle, said accessory comprising: a mounting structure configured to mount at a vehicle; wherein said mounting structure is configured to adjustably mount at the vehicle so as to be adjustable about a horizontal pivot axis relative to the vehicle; a support structure comprising a vehicle end and an attaching end, wherein said vehicle end is attached to said mounting structure via a cushioning assembly; an accessory attached at said attaching end of said support structure; wherein said cushioning assembly comprises (i) a first element attached at said vehicle end of said support structure, (ii) a second element attached at said mounting structure, and (iii) a plurality of resilient elements disposed between said first element and said second element; wherein said first element comprises a non-circular receiver fixedly attached at said vehicle end of said support structure, and wherein said second element comprises a non-circular beam that is received within said receiver and that engages said plurality of resilient elements; wherein each of said resilient elements is compressible and biased towards its initial form; and wherein, responsive to pivotal movement of said mounting structure about said horizontal pivot axis, said beam pivots within said receiver to compress at least some of said resilient elements. ### Claim 17 (depends on 16) The accessory assembly of claim 16, wherein said receiver comprises a square cross section shape and wherein said beam comprises a square cross section shape. ### Claim 18 (depends on 16) The accessory assembly of claim 16, wherein said beam is movably attached at said mounting structure. ### Claim 19 (depends on 18) The accessory assembly of claim 18, wherein said beam is received through slots of respective brackets of said mounting structure, and wherein said slot of each of said brackets comprises an elongated slot that allows for movement of said beam relative to said mounting structure in a first direction and limits movement of said beam relative to said mounting structure in a second direction orthogonal to said first direction. ### Claim 20 (depends on 19) The accessory assembly of claim 19, wherein each of said elongated slots allows for movement of the respective end of said beam at that slot relative to the other end of said beam to allow for oscillation of said accessory.
