Abstract: A draper cutting platform for use with an agricultural harvester includes a pair of side platform sections, with each side platform section including a side belt. A center platform section is disposed in an area between the side platform sections. The center platform section includes at least one alignment device and at least one latch. A center conveyor assembly is removably attached to the center platform section, and carries a center belt. The center conveyor assembly includes at least one mating alignment device and at least one mating latch.

Abstract: A hitch flexing hinge included within the draft beams of an implement frame of the type that enables vertical flexing of the frame sections. The hinge includes a yoke attached to the drawbar of a draft vehicle and a body section that is received in one end of the draft beam. The body portion carries a swivel ball and attachment of the draft beam to the swivel ball allows rotational twisting of the draft beam about its longitudinal axis as the implement frame sections flex.

Abstract: A forwardly foldable implement frame having a horizontal pivot or flex hinge to enable vertical flexing of the wing sections to follow the ground contour. The frame includes a pair of cam bumpers rigidly attached to the wing beam in near proximity to the flex hinge. Folding of the wing sections toward one another causes the cam bumpers to contact and automatically lock out the flex hinge.

Abstract: A transmission and drive assembly for a planter that can be transversely positioned on and selectively clamped on the planter frame at desired locations out of interfering relationship with the planting units. The transmission is at the end of the frame outside of the outermost planter unit but may be easily repositioned on the frame as is necessary. A ground wheel assembly is secured to so as to optionally extend to the front or rear of the frame. It may also be adjusted transversely to accommodate adjustments in the row spacings. The dual assembly includes a countershaft journaled on both the transmission and the wheel assembly bracket and driven by the ground wheel through ratchet assemblies. The transmission is also securable to the frame to extend either to the front or the rear thereof. A crossover drive assembly is provided for transferring drive from the front to the rear of the frame when the transmission is mounted to extend to the front of the frame.
