A foldable implement carrier is disclosed including a central support bar supporting two pivotally connected tool bar sections which are movable from a laterally extended position to a folded position to reduce the width of the foldable implement carrier for transport. The tool bar sections have pivot columns which are rotationally received within a H-shaped frame member. A main wheel set is privotally connected to a frame, which includes the H-shaped member and the central support member, and is driven vertically downwardly to raise the frame off of the ground. The first and second tool bar sections are driven to pivot within the H-shaped frame member and move from the extended position to the folded position. Each tool bar section includes a latch and a wheel to secure the tool bar section to the central support bar. When folded, the latches are received upon the top of the central support bar and the wheels are retracted and abut a lower portion of the central support bar. The tool section can also flex with respect to the frame when traveling over uneven terrain.
