Abstract: The agricultural roller has three rolls mounted in a triangular overlapping operable configuration. The wing rolls are movable about a pair of spaced-apart transversal articulations between the wing roll frameworks and a central framework enclosing the central roll. The transversal articulations are positioned near a respective end of the central roll such that adjacent roll ends move up and down in unison. The central framework is also movable about a longitudinal articulation across the rear end of a trailer frame. The diameter of the central roll is larger than the diameter of wheels on the trailer frame such that the wheels are raisable off the ground when the rolls are deployed in an operable mode. In a towable configuration, the central roll is moved above the trailer frame and the wing rolls are moved above the central roll with their respective axes aligned forwardly.
