Abstract: A lock for an implement turnbuckle includes an apertured plate attached directly to the turnbuckle. The plate receives the pin or linkage connecting structure that attaches to the threaded eyebolt of the turnbuckle. The mounting end of the plate opposite the slot is secured against a flat on the internally threaded member of the turnbuckle by a U-bolt. The plate prevents relative rotation between the eyebolt and an internally threaded member receiving the eyebolt to thereby maintain the desired turnbuckle length adjustment.

Abstract: A contaminant-resistant bearing assembly includes a multi-lip seal with an extended shroud supported from the outer ring and projecting adjacent a stepped inner ring shoulder. A steel slinger supported from the inner ring is offset outwardly adjacent the shroud and includes a radially outer edge terminating closely adjacent the connection of the seal shroud to the outer ring. The slinger includes an outer portion angled inwardly from the radial direction and supporting a lip seal which contacts an angled portion of the seal shroud at a central location between the rings. A primary step machined on the inner ring prevents the slinger from being pushed into the seal.

Abstract: A forward acting wheel arm for a drawn hitch includes a pivot point directly below the rear rank of the machine frame, and the wheels are rotated directly in front of the front rank during field operation. For transport, the wheels rotate below the front rank to minimize tongue-lightness. The need for stabilizer wheels on the rear of the machine is eliminated, and the wheel arms can be actuated with either series or parallel hydraulic cylinders. The wheel arm pivot and cylinder base end connection are both located on the same support plate, and the hydraulic cylinder force is internalized within the plate rather than being translated through the wheel module mounting hardware.
