ABSTRACT:
Mounted on a tractor is a sloper assembly which is adapted to push earth and debris away from a berm of a road. A support stand is pivotally connected to the tractor for rotation about a vertical axis. A first outrigger arm is pivotally connected to the support stand and extends outwardly therefrom. A first hydraulic cylinder is pivotally connected between the support stand and the first outrigger arm. A second outrigger arm is pivotally connected to the first outrigger arm and supports a sloper assembly. A second hydraulic cylinder is attached between the first outrigger arm and the second outrigger arm. A third hydraulic cylinder is operatively connected between the second outrigger arm and the sloper assembly. A fourth hydraulic cylinder, having overload protection, is operatively connected between the tractor and the support stand. Therefore, the entire support stand, first and second outrigger arms and the sloper assembly will pivot horizontally about the vertical axis when the sloper assembly meets an obstruction, to avoid damaging the tractor and the sloper assembly.
