Abstract: A method of manual control neutral drift correction for a work vehicle is characterized by the steps of: sensing a position of a first manual control using a first position sensor when an activation switch is activated, wherein the first position sensor generates a first input signal; sending the first input signal to a controller; retrieving a stored first manual control neutral position value from a memory unit; calculating a first corrected manual control neutral position value using the controller, wherein the first corrected manual control neutral position value is calculated using the first input signal and the first manual control position value; and utilizing the first corrected manual control neutral position value to generate a first control signal for operating a first electro-hydraulic valve, wherein the first control signal is generated by the controller to operate the first electro-hydraulic valve to effect movement of a first assembly.

Abstract: A side swing hitch for a rear end of an agricultural combine. The hitch includes a hitch support bracket having opposite end portions and an intermediate portion therebetween, a first of the end portions including at least one element for mounting to a rear chassis member of the combine with the other end portion suspended in a position rearward of the rear axle assembly connected to the chassis member. A draw bar is pivotally mounted to the second end portion of the hitch support bracket for pivotal movement between a rearwardly extending towing position generally perpendicular to the rear axle assembly and at least one generally transversely extending stored position at least generally perpendicular to the towing position and beside the rear axle assembly, the draw bar having an opposite end including a hitch element connectable to a tongue of a vehicle such as a trailer or cart to be towed by the combine.

Abstract: A utility vehicle is provided with a middle axle that is mounted at the end of a bogey beam for both flotational and oscillatory movement relative to the frame of the vehicle. The middle axle is restrained longitudinally by support links that are pivotally connected to the frame at a location that is forward of the rear drive axle. The middle axle is formed by a pair of stub axles interconnected by a support beam that is pivotally connected to the rearward end of the bogey beam. Vertical movement of the middle axle support wheels results in a corresponding vertical movement of the rearward end of the bogey beam and a rotation of the support beam about its pivotal connection on the bogey beam. The oscillatory movement is accomplished by a pivotal connection via a ball joint between a central support bracket mounting the transverse support beam to the longitudinally extending bogey beam.

Abstract: An agricultural baler for making cylindrical bales of crop material has a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an apron to define a bale forming chamber. A mechanism is linked directly to and moves with the sledge assembly for dispensing sheet material into the bale forming chamber where it is wrapped around a cylindrical bale of crop material. A simple assembly operated by an actuator piston that moves with the sledge rollers is used to initially feed the wrap material between the sledge rollers and the crop material and then to withdraw the dispenser when the bale is wrapped while simultaneously cutting the wrap material from its feed roll.
