  • Patent number: 5580205
    Abstract: A four-wheeled vehicle which allows a user to carry and distribute a bale of hay. The vehicle includes a rotatable table, i.e. a turntable, and a frame. The frame includes axles and spindles for the attachment of wheels and bearings for the rotative support of the turntable. The turntable rotates along four support bearings disposed near its periphery and a thrust bearing disposed near the center of the turntable. Steering is accomplished by pivoting a handle attached to the front axle, above which is a pair of six inch discs pivotally engaged to each other by a pin. The discs distribute the load and reduce the force on the pin, i.e. pivot point, thereby resulting in an easily steered vehicle.
