Abstract: A front folding tool carrier bar for agricultural applications includes a frame having opposite sides and having ground-engaging wheels mounter thereon. Mounted on the frame is a device for coupling the frame to a vehicle. Also mounted on the frame are a pair of forwardly folding wing bars having first and second ends, each of the first ends pivotally mounted on the frame such that the wing bars may pivot about a substantially vertical pivot axis between a forwardly folding transport position and a transversely extended working position. Each wing bar is pivotally mounted at opposite sides of the frame. For securing the wing bars in transversely extended working position, a pair of outrigger braces extend outwardly from the frame and are connected to opposite wing bars whereby the wing bars may be braced in working position. Mounted on each wing bar is at least one ground-engaging wheel. Finally, a device for pivoting the wing bars between the transport position and the working position is provided.
