Abstract:
1. An implement attaching to a vehicle, comprising: a linkage assembly; and a work assembly with an edge, said work assembly also including a dynamic skid shoe, said dynamic skid shoe including: a surface contact component for contacting a street surface, a dynamic component operably connected to the surface contact component for providing vertical movement of the surface contact component, and a hydraulic fluid circuit including a pressure providing component fluidily connected to the dynamic component, wherein said linkage assembly is attachable as an attachment between the work assembly and the vehicle, the linkage assembly having first and second configurations, the first configuration providing the edge to scrape along a path following with prevailing ground surface, the second configuration providing the edge to be elevated above the prevailing ground surface in order to pass over an obstruction encountered by the edge as the edge moves in a forward direction, the edge moving about the dynamic skid shoe as the linkage assembly goes from the first configuration to the second configuration.
