Abstract:
A horizonally folding agricultural implement, such as a corn planter, comprising a main frame section with a hitch extending perpendicular therefrom for attachment to a vertically movable drawbar of a farm tractor, and a forwardly folding end wing section hinged to each outer end of the main frame section by a generally vertical pivot hinge, with the pivot hinge including a first and second set of pivot bushings rigidly attached to the abutting ends of the main frame section and the end wing sections respectively in vertical axial alignment with each other, the top end of the pivot pin having a mounting plate secured thereto, with a first hydraulic actuating assembly having one end operatively connected to the rigid plate and the other end operatively connected to the main frame section, and a second hydraulic actuating assembly having one end operatively connected to the rigid mounting plate and the other end thereof operatively connected to the folding wing section, thereby, upon actuation of the hydraulic actuating assembly in the wing sections are aligned with the main frame section in the operating, or planting position, the pivot pin is rotated approximately 90 degrees, thereby swinging the folding wing sections forward approximately 90 degrees, and, simultaneously therewith, the actuation of the second hydraulic actuating assembly rotates the folding end wing section forward an additional 90 degrees about the pivot pin to a position generally parallel to and adjacent the main frame section to reduce the overall width of the agricultural implement for transport purposes.
