An agricultural implement has a hitch frame, a center frame pivotally attached rearward of the hitch frame about a hitch pivot axis. Wing frames are pivotally attached to ends of the center frame and a center actuator is pivots the center and wing frames from a rearward extending operating position to an upward extending transport position. Caster wheels are pivotally mounted on front sides of the wing frames about caster and transport axes. In the operating position, the caster axes are oriented vertically and the transport axes are oriented horizontally, and in the initial transport position, the caster axes are oriented horizontally, perpendicular to the hitch pivot, the transport axes are oriented vertically, and caster wheel actuators pivot the caster wheels 90 degrees about the transport axes to align the caster axes with the hitch pivot axis. The caster wheels support the wing frames in both operating and transport positions.

A rotary mower apparatus includes a center section with a center blade, inner wings with inner and middle blades, and outer wings with outer blades. Rear wheels support rear ends of the decks, and gauge wheels support front portions of the outer wings. A transport mechanism folds the outer wings upward to a transport position over the inner wings, and then folds the inner wings to a transport position upright from outer edges of the center section. A drive is operative to rotate each blade. Beneficially axes of the blades are oriented alternately forward and rearward across a width of the apparatus. A disclosed drive has a main gear box adapted at an input thereof for attachment to a rotating power source, and slip clutch protected power shafts are connected to outputs of the main gear box to drive the blades.
An agricultural implement has a center frame supported on center wheels and right and left interframes are pivotally attached to corresponding ends of the center frame about wing pivot axes. Right and left wing frames are pivotally attached at front inner ends thereof to front ends of corresponding interframes about front interframe pivot axes. Rear inner portions of the wing frames are movably attached to corresponding interframes. Latch mechanisms selectively lock the rear inner pottions each wing frame to rear portions of the corresponding interframes. A center actuator pivots the center frame such that the frames move from an operating position extending rearward to an initial transport position extending upward where the interframes and wing frames can pivot rearward about the upright wing pivot axes. The front interframe pivot axes are oriented perpendicular to the wing pivot axes.
