SLOPE MOWER Abstract A mower vehicle includes a vehicle frame and single front and rear driven wheels. The vehicle is adapted to conform generally to slopes and the like by maintaining the frame in a generally upright orientation. First and second blade housings are pivotally connected to the frame and swingable about an axis extending longitudinally of the frame. The first and second blade housings extend laterally from opposite sides of the frame. Each blade housing carries a driven cutting blade. The blade housings are open to one another and have a shared discharge passage at a center rear section thereof. The blades overlap slightly and rotate in synchronized reverse rotations relative to one another. Hydraulic cylinder assemblies are provided to actuate the first and second blade housings about the longitudinal axis in response to changes in slope of the surrounding terrain. A leveling system is provided for sensing changes in attitude of the vehicle frame, and for consequently actuating the hydraulic assemblies to maintain the vehicle frame in a generally upright position and the first and second blade housings in operative contact with the ground.
