Abstract: A land roller implement is towed by an agricultural tractor for levelling land. The implement has a main frame and two wing assemblies pivotal from a working field position extending laterally outward in opposing directions from the main frame to a transport position extending rearwardly from the main frame. The implement has a set of transport wheels for transporting the rollers of the implement spaced above the ground in the transport position, the wheels including: (i) two leading wheels on the main frame, (ii) two trailing wheels at the outer ends of wing assemblies, and (iii) two steerable wheels supported on the wing assemblies forwardly of the trailing wheels. The steerable wheels can be controllably pivoted by an actuator into a transport configuration oriented for forward rolling in transport, while the other wheels are freely pivotal to shorten the turning radius of the towed implement.
