Abstract: An improved toolbar implement is described comprising a main support bar for attachment to a tractor, a pair of folding wings supported on a wheel assembly and connected to the main support bar, and a plurality of ground working tool assemblies attached to each of the folding wings and the main support bar. The folding wings pivot about an axis set-back rearwardly from the main support bar to allow clearance of the ground working tools as the wings are moved from a transversely extended working position to a rearwardly extended transport position.
