Rear folding toolbar implement

摘要

Each wing of a rear folding implement has a wing frame supported on rear wheels for movement along the ground, and a forewing frame and wheel pivotally attached to the wing frame. A center ball joint pivotally connects right and left inner wings and a center wheel assembly supports the center ball joint. The wings extend laterally and the forewing frames are in a lowered position supported on their wheels when in the operating position. To move the wings into a transport position, the implement is towed forward and the wings pivot about the center ball joint to trail rearward and the forewing frames are moved upward to narrow the implement for transport. An air seeder cart hitch is rearward of and near the center ball joint in the operating position, and when the wings trail rearward the cart hitch is near rear ends of the trailing wings.

主权项

1. A rear folding implement apparatus comprising:
a plurality of wings, each wing comprising: a wing frame supported on rear wheels for movement along the ground; a forewing frame pivotally attached to the wing frame about a substantially horizontal forewing pivot axis oriented substantially perpendicular to an operating travel direction when the forewing frame is in a field operating position; a forewing wheel mounted to a forward portion of the forewing frame; a forewing actuator mounted on the wing frame and operative to pivot the forewing frame from a raised position, where the forewing frame extends upward from the wing frame with the forewing wheel above the ground, to a lowered position where the forewing frame extends forward from the wing frame, and the forewing wheel supports the forewing frame for movement along the ground; and a plurality of ground engaging tools mounted on the wing frame and on the forewing frame; wherein when right and left wings are in a field operating position the wings extend laterally substantially perpendicular to the operating travel direction, and the forewing frames of the wings are in the lowered position; and wherein when the right and left wings are in a transport position the wings extend rearward side by side and substantially in alignment with the operating travel direction, and the forewing frames are moved to the raised position.
