Abstract: In one or more arrangements, a sweep system for livestock grazing is provided to facilitate movement of livestock when an enclosure is moved. The system includes a frame having a front end, a rear end, and opposing sides. The system has one or more wheel assemblies attached to the frame to facilitate movement of the frame along the ground. The system includes a sweep mechanism connected to the frame that facilitates movement of the livestock.

Abstract: A stator vane includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII, Table VIII, Table IX, Table X, Table XI, or Table XII. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.
