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.

We claim: 1. A crop lifter and air assist feeding assembly for a floating cutter bar header comprising: a lower tube that is generally horizontal, an upper tube, integral with a forward end of the lower tube, and extending rearwardly and upwardly from the forward end of the lower tube to an air discharge orifice, a vine lifting rod attached to the upper tube and extending rearwardly and upwardly from the air discharge orifice, a vertical tongue with a crop lifter support bore attached to the lower tube and extending upwardly from the lower tube, a threaded vertical bore integral with a rear portion of the lower tube; and a rear air inlet collar integral with the lower tube, a knife guard with a guard forward tip received in the crop lifter support bore, and a lower tube retainer bolt that passes through a flexible cutter bar, the knife guard and screws into the threaded vertical bore and clamps the lower tube to the cutter bar; a skid plate assembly clamped to the cutter bar, a terminal air supply tube connected to the skid plate assembly, passing through a passage through an upturned front section of the skid plate assembly and having a terminal air supply forward end telescopically connected to the rear air inlet collar on the lower tube; and an elastic and flexible tube positioned above the skid plate assembly and having a flexible tube forward end connected to an air receiving end of the terminal air supply tube and a flexible tube rear end connected to a blower air delivery tube forward of an upturned rear section of the skid plate assembly. 2. A crop lifter and air assist feeding assembly, as set forth in claim 1 including an air deflector in the forward end of the lower tube that changes the direction of movement of air moving from the lower tube to the upper tube. 3. A crop lifter and air assist feeding assembly, as set forth in claim 1 including a plastic jacket that covers a portion of the downwardly facing outer surfaces of the lower tube and a portion of the upwardly facing outer surface of the upper tube. 4. A crop lifter and air assist feeding assembly, as set forth in claim 1, including a diffuser adjacent to the air discharge orifice that directs the flow of air from the discharge orifice. 5. A crop lifter and air assist feeding assembly for a floating cutter bar header comprising: a lower tube that is generally horizontal, an upper tube, integral with a forward end of the lower tube, and extending rearwardly and upwardly from the forward end of the lower tube to an air discharge orifice, a vine lifting rod attached to the upper tube and extending rearwardly and upwardly from the air discharge orifice, a diffuser secured to the lower tube and the upper tube and including a pair of spaced apart vertical plates having their forward ends positioned at the air discharge orifice, extending rearwardly from the air discharge orifice and laterally outward away from each other, a top plate integral with an upper edge of each of the pair of spaced apart vertical plates and extending upward and rearward from the air discharge orifice, a vertical tongue with a crop lifter support bore attached to the lower tube and extending upwardly from the lower tube, and a rear air inlet collar integral with the lower tube; a knife guard clamped to a flexible cutter bar with a guard forward tip received in the crop lifter support bore; a skid plate assembly clamped to the cutter bar, a terminal air supply tube connected to the skid plate assembly, passing through a passage through an upturned front section of the skid plate assembly and having a terminal air supply forward end telescopically connected to the rear air inlet collar on the lower tube; and an elastic and flexible tube positioned above the skid plate assembly and having a flexible tube forward end connected to an air receiving end of the terminal air supply tube and a flexible tube rear end connected to a blower air delivery tube forward of an upturned rear section of the skid plate assembly. 6. A crop lifter and air assist feeding assembly, as set forth in claim 5 including an air deflector in the forward end of the lower tube that changes the direction of movement of air moving from the lower tube to the upper tube. 7. A crop lifter and air assist feeding assembly, as set forth in claim 5 including a plastic jacket that covers a portion of the downwardly facing outer surfaces of the lower tube and a portion of the upwardly facing outer surface of the upper tube. 8.
