Abstract: A riding mower includes a frame, front steering wheel, two rear wheels and two mower blade housings located laterally relative to the frame with blades located within the housings. Telescoping drive shafts extend generally longitudinally from a belt drive mechanism located at a rearward end of the frame to the blade housings to drive each of the blades within the housings. Hydraulic cylinder assemblies and a leveling system are provided to pivot the frame with respect to the rear wheels and about a longitudinal axis in response to changes in slope of the surrounding terrain, maintaining the frame in a generally upright orientation. The telescoping drive shafts extend and retract in response to the angular movement of the frame with respect to the blade housings that remain close to the ground surface.

Abstract: A bale wrapping apparatus having an infeed conveyor, a wrapping mechanism and an outfeed conveyor synchronized to convey bales through the apparatus while continuously wrapping a bale in the wrapping mechanism and forming a continuous protective cocoon around a row of bales. The wrapping mechanism includes a rotating cage and a pair of film dispensers that cooperatively wrap layers of film in successively overlapping helically wound paths around the bale. The apparatus is self-motivated when wrapping so as to discharge a continuous row of wrapped bales.

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. In an alternative embodiment, wheeled side frames are biased by hydraulic cylinders to maintain the vehicle frame in an upright position and associated blade housings are allowed to float relative to the side frames.
