Abstract

A snow plow assembly has a push frame, a lift frame, and a coupling configured to attach the push frame to a lift frame. The coupling attaches the left and right sides of the push frame to the corresponding left and right sides of the lift frame, and each coupling being independently vertically floatable to allow the push frame to float vertically relative to the lift frame, while also allowing the push frame to rotate relative to the lift frame to accommodate for irregular or uneven ground surfaces. The couplings each include a bearing block that extends through an opening in the push frame and a retaining member that extends through an opening in the bearing block for operatively coupling the push frame to the lift frame. The bearing block facilitates distribution of load between the push frame and retaining member to reduce wear on the push frame.

Dependent claims

A snow plow assembly for a vehicle, the snow plow assembly comprising:

a push frame to which a moldboard is mountable for enabling removal of snow;
a lift frame configured for mounting to the vehicle;
a lift device mounted to the lift frame, the lift device configured to vertically raise or lower the push frame and the moldboard relative to a horizontal plane;
and
at least one coupling, attaching a side of the push frame to a corresponding side of the lift frame;
wherein the at least one coupling includes a block that receives a retaining member that operatively couples the side of the push frame to the lift frame;
and
wherein the block of the at least one coupling is configured to slidably move vertically when the snow plow assembly is in use to thereby allow the side of the push frame to float vertically relative to the side of the lift frame, and are configured to allow the side of the push frame to float vertically, thereby allowing the push frame to rotate relative to the lift frame about a longitudinal axis extending in a forward direction, which enables the snow plow assembly to accommodate for irregular or uneven ground surfaces when the snow plow assembly is in use.

A snow plow assembly for a vehicle, the snow plow assembly comprising:

a push frame to which a moldboard is mountable for enabling removal of snow;
a lift frame configured for mounting to the vehicle;
a lift device mounted to the lift frame, the lift device configured to vertically raise or lower the push frame and the moldboard relative to a horizontal plane;
and
a coupling configured to couple the push frame to the lift frame, the coupling including a block and a retaining member;
wherein the retaining member is configured to operatively couple the push frame to the lift frame while permitting the push frame to float vertically relative to the lift frame,
wherein the block is interposed between the retaining member and the push frame, the block being configured to distribute at least some load exerted on the push frame to the retaining member, thereby reducing wear on the push frame when the snow plow assembly is in use, and;
wherein the block is at least partially interposed between the push frame and the retaining member in both a longitudinal rearward direction and a longitudinal forward direction to cause the retaining member to preferentially engage the block, while restricting the retaining member from engaging the push frame, when the snow plow assembly is pushing or pulling snow.
