Abstract
An implement apparatus includes a hitch frame, center frame section, and right and left wing sections pivotally attached to the center section. An actuator pivots the center frame section upward about the hitch frame axis at the rear of the hitch frame to raise the frame sections upward and rearward from a horizontal aligned operating position, where front ends of the frame sections are forward of the hitch frame axis, to a raised position where the frame sections are oriented vertically. Working members mounted to the frame sections forward of the hitch frame support the apparatus on the ground in the operating position, move upward off the ground in the raised position. Transport wheels rearward of the hitch frame axis are above the ground in the operating position, and move down to support the apparatus in the raised position, where wing sections can pivot rearward to the transport position.
