Abstract
A roller assembly, for use with a hydraulically-powered, truck-mounted, standard snowplow lift having three attach points, is provided with a rigid frame, a roller rotatably supported in the frame, a saddle bracket pivotally attached to the frame and to two of the snowplow lift attach points, and a tongue member also pivotally attached to the frame and to another one of the three snowplow lift attach points, the assembly frame being rotatable relative to the frame through a limited range to accommodate changes in curvature of a roadway surface.
