Claim:
1. A land roller implement for rolling movement across the ground in a forward working direction of a towing vehicle, the land roller implement comprising: a central frame; a hitch member connected to the central frame and arranged for connection to the towing vehicle for movement therewith in the forward working direction; a first wing which is elongate in a longitudinal direction between an inner end pivotally coupled on the central frame and an opposing outer end; a second wing which is elongate in a longitudinal direction between an inner end pivotally coupled on the central frame and an opposing outer end; the first and second wings being pivotal about respective upright axes between respective working positions spanning laterally outward in opposing directions from the central frame so as to be oriented transversely to the forward working direction and respective transport positions extending rearwardly from the central frame such that the longitudinal direction of the first and second wings extends generally in the forward working direction; each of the first wing and the second wing comprising an inner roller and an outer roller supported on the wing for rolling movement in the forward working direction in the working position of the wings; the inner roller and the outer roller of each wing being spaced apart in the longitudinal direction of the wing by a respective gap between the rollers; each of the first wing and the second wing further comprising a packer wheel axle rotatably supporting a packer wheel thereon in which the packer wheel axle is supported on the wing for pivotal movement about an upright axis relative to the wing between a transport position in which the packer wheel axle is oriented transversely to the longitudinal direction of the wing such that the packer wheel is supported for rolling movement across the ground in the forward working direction in the transport position of the wings and a working position in which the packer wheel axle is oriented substantially parallel to the longitudinal direction of the wing such that the packer wheel is supported for rolling movement across the ground in the forward working direction in the working position of the wings; each packer wheel being aligned with the respective gap between the inner roller and the outer roller of the respective wing in the working position of the packer wheel axle.
