Abstract: The center-pivot vehicle has forward and rearward sections with traversing means for traversing terrain. A rotary actuator connects the forward and rearward sections. Rotation of the rotary actuator articulates the forward and rearward sections relative to each other for steering the vehicle. One of the sections includes a bed operably attached to a bed frame that is operably attached to a trailer frame for actuated movement between trailing and loading positions. The bed is pivotally attached to the bed frame for moving between tilted and non-tilted positions.

Abstract: The invention relates to a load lifting trailer including a frame and a bed operatively attached to the frame for actuated movement between trailing and loading positions. A pivot plate having first, second and third connectors pivotally attach the frame to the bed and to each other, and when actuated by a linear extensible actuator provides the necessary force for moving the bed relative to the frame of the trailer up and down between trailing and loading positions.

Abstract: The center-pivot vehicle has forward and rearward sections with traversing means for traversing terrain. A rotary actuator connects the forward and rearward sections. Rotation of the rotary actuator articulates the forward and rearward sections relative to each other for steering the vehicle. The present invention also includes a method for controlling articulation of a center-pivot vehicle which includes connecting first and second sections of the center-pivot vehicle together with a rotary actuator, powering the rotary actuator with an engine and providing a steering input by an operator for operating the rotary actuator for rotating the rotary actuator and articulating the first and second sections of the vehicle relative to each other for turning the vehicle.

Abstract: The invention relates to a portable load lifting bed including a base frame and a bed frame moveably mounted for movement between an upper position and a lower position. A plurality of guides connect the bed to the base frame and at least one actuator provides force for moving the bed frame between the upper position and the lower position.

Abstract: A livestock pen includes a rectangular horizontal platform having a plurality of sidewall assemblies connected thereto and extending around the perimeter thereof. At least one of the sidewall assemblies includes first and second vertical posts spaced apart from one another to form a gate opening therebetween. An upper horizontal rail is connected to the upper end of one of the gate posts and extends horizontally away from the gate opening. A horizontal slide rail is attached to the one sidewall assembly and extends across the gate opening adjacent the lower end thereof. A gate includes an upper channel member slidably mounted over the upper rail of the rear wall assembly and a lower sleeve member telescoped over the slide rail at the bottom of the wall assembly so as to permit the gate to slide between open and closed positions.

Abstract: A bale carrier comprising a horizontally disposed U-shaped frame having an open rearward end and a forward end. The U-shaped frame includes first and second side frame members having a front frame member secured thereto and extending between the forward ends thereof. A rocker shaft is rotatably supported by the front frame member and has a hitch secured thereto which extends forwardly therefrom for connection to a prime mover. Rearwardly extending elongated members are secured to opposite ends of the rocker shaft so that longitudinal movement of the elongated members causes the rocker shaft to be rotated. Wheel supports are pivotally secured to the side frame members adjacent the rearward ends thereof and are pivotally connected to the rearward ends of the elongated members. A ground-engaging wheel is mounted on each of the wheel supports whereby pivotal movement of the wheel supports, relative to the side frame members, causes the U-shaped frame to be raised and lowered with respect to the ground.

Abstract: A bale carrying device comprised of a cross bar frame structure having a pair of spaced apart rearwardly extending arms pivotally mounted on the ends of the cross bar frame structure for pivotal movement about the vertical axis of the cross bar; and having means for laterally adjusting the pivotal axis of the arms for selectively varying the width of the space between the arms in order to accommodate large round bales of varying thicknesses.
