Patent ID: 8732988

Claim:
An implement attaching to a vehicle, comprising: a snow blower with an edge; a first dynamic skid shoe connected to a first side of the snow blower; a second dynamic skid shoe connected to a second side of the snow blower, the first side opposing the second side along a width direction of the snow blower, the first dynamic skid shoe includes a first surface contact component for contacting a street surface, and a first dynamic component operably connected to the first surface contact component, and the second dynamic skid shoe includes a second surface contact component for contacting the street surface, and a second dynamic component operably connected to the second surface contact component; a fluid circuit including a pressure providing component, said pressure providing component fluidily connected to both the first dynamic component and the second dynamic component, the first dynamic component being configured to be dynamic for providing vertical movement of the first surface contact component based on pressures from the first surface contact component and the pressure providing component, or be rigid, and the second dynamic component being configured to be dynamic for providing vertical movement of the second surface contact component based on pressures from the second surface contact component and the pressure providing component, or be rigid; a sensor connected to the fluid circuit, the sensor configured to detect the edge of the snow blower striking an obstruction, wherein when the edge strikes the obstruction, the sensor detects the edge striking the obstruction, the sensor communicates to the fluid circuit to close the fluid circuit so that the first dynamic component becomes rigid and the second dynamic component becomes rigid, and the edge is elevated to allow the edge to ride over the obstruction.
