The crop lifter and air assist feeding assembly for a floating cutter bar header includes a lower tube that is generally horizontal. An upper tube is fixed to the front end of the horizontal tube and extends upwardly and rearwardly to an air discharge orifice. A vine lifting rod is attached to the upper tube. The lower tube is mounted under a knife guard. A skid plate connected to the cutter bar has an attached terminal air supply tube. The terminal air supply tube passes through a front portion of the skid plate and attaches to the lower tube. An elastic and flexible tube is positioned above the skid plate, and is connected to the terminal supply tube and to terminal air supply tube and a blower air delivery tube under the skid plate.
