Abstract:
1. A land roller implement apparatus comprising: a center section comprising a center frame, a hitch at a front end of the center frame adapted for attachment to a towing vehicle, and a center roller rotatably mounted to the center frame about a center roller axis oriented substantially perpendicular to an operating travel direction; the center frame comprising right and left wing brackets extending rearward from corresponding right and left locations on the center frame, wherein each wing bracket is pivotally attached at a front end thereof to the center frame about a bracket axis oriented substantially horizontal and perpendicular to the operating travel direction; a right center wheel movably mounted under the right wing bracket and a left center wheel movably mounted under the left wing bracket; a right and left wing, each comprising a wing frame and a wing roller rotatably mounted to the respective wing frame about a wing roller axis, pivotally mounted to each wing bracket about a substantially vertical transport axis and about a pivot axis oriented substantially horizontal and perpendicular to the wing roller axis; right and left bracket locks operative when engaged to lock the respective wing bracket with respect to the bracket axis to prevent rotation of the wing bracket about the bracket axis; right and left transport actuators operative to move said right and left center wheels down such that, when said bracket locks are engaged, right and left wing brackets move up to a transport position; right and left wing wheels movable from a raised operating position above the ground to a lowered transport position supporting corresponding right and left wings above the ground; wherein the right and left wings are movable from an operating position with the center and wing rollers resting on the ground, and extending laterally from corresponding right and left wing brackets such that the wing roller axes are substantially perpendicular to the operating travel direction and such that inner ends of said right and left wing rollers are rearward of and overlap corresponding right and left ends of the center roller, to the transport position with the center and wing rollers supported above the ground and where the right and left wings extend rearward from the corresponding right and left wing brackets such that the wing roller axes are substantially aligned with the operating travel direction;
