Patent attributes
A plow assembly includes a mounting structure configured to mount at a vehicle, a center plow attached at the mounting structure, and a plow wing mounted at an end of the center plow via a first attachment assembly and a second attachment assembly. Each of the first and second attachment assemblies includes an elongated attachment element and a biasing element. The elongated attachment element attaches a respective rear portion of the plow wing at the center plow and engages the biasing element at the rear of the center plow. The biasing element allows for movement of the attachment element at the rear of the center plow to allow for pivotal movement of the plow wing relative to the center plow. The biasing element limits pivotal movement of the plow wing and biases the plow wing towards a neutral state, where the plow wing is generally normal to the center plow.
