An auger for a vertical livestock feed mixer having an open-top mixing tub is provided. The auger includes two flights to draw in feed components from the bottom of the mixer tub and move them to the top. The trailing edge of the upper auger flight includes an upraised portion to deflect feed components towards the sidewalls of the feed mixer. The leading edge of the lower auger flight includes a kicker plate on the topside of the flight to deflect feed components towards the centre of the auger.

We claim: 1. An auger for a feed mixing tub, comprising: a) a substantially vertical pipe having upper and lower ends; b) a spiral flight disposed about the circumference of the pipe, the spiral flight extending from the lower end to the upper end of the pipe, the spiral flight forming less than two complete 360-degree auger flights, the spiral flight having a leading edge near the lower end of the pipe and a trailing end near the upper end of the pipe, the leading edge wider than the width of the spiral flight near the upper end, the auger flights comprising a pitch spacing that is greater in dimension than the width of the auger flights; c) a kicker disposed on the spiral flight near the leading edge for deflecting feed mix towards the centre of the auger when the auger is rotating in the mixing tub; and d) an upturned portion disposed on the spiral flight near the trailing end for deflecting feed mix away from the centre of the auger when the auger is rotating in the mixing tub. 2. The auger as set forth in claim 1 further comprising fastening means for fastening the auger to a mixer drive unit disposed in the mixing tub. 3. The auger as set forth in claim 1 wherein the spiral flight further comprises at least one knife slot for operatively attaching a knife for cutting feed mix when the auger is rotating in the mixing tub. 4. The auger as set forth in claim 3 further comprising the knife disposed in the knife slot. 5. The auger as set forth in claim 1 wherein the spiral flight further comprises at least one brace for reinforcing the spiral flight. 6. The auger as set forth in claim 5 wherein the at least one brace is disposed on the underside of the spiral flight. 7. The auger as set forth in claim 1 wherein the spiral flight further comprises at least one wear plate disposed near the leading edge. 8. The auger as set forth in claim 1 wherein the kicker further comprises a kicker wear plate. 9. A feed mixer, comprising: a) a feed mixing tub; b) at least one auger disposed in the mixing tub, comprising: i) a substantially vertical pipe having upper and lower ends, ii) a spiral flight disposed about the circumference of the pipe, the spiral flight extending from the lower end to the upper end of the pipe, the spiral flight forming less than two complete 360-degree auger flights, the spiral flight having a leading edge near the lower end of the pipe and a trailing end near the upper end of the pipe, the leading edge wider than the width of the spiral flight near the upper end, the auger flights comprising a pitch spacing that is greater in dimension than the width of the auger flights, iii) a kicker disposed on the spiral flight near the leading edge for deflecting feed mix towards the centre of the auger when the auger is rotating in the mixing tub, and iv) an upturned portion disposed on the spiral flight near the trailing end for deflecting feed mix away from the centre of the auger when the auger is rotating in the mixing tub; c) a mixer drive unit for rotating the auger; and d) fastening means for fastening the auger to the mixer drive unit. 10. The feed mixer as set forth in claim 9 wherein the spiral flight further comprises at least one knife slot for operatively attaching a knife for cutting feed mix when the auger is rotating in the mixing tub. 11. The feed mixer as set forth in claim 10 further comprising the knife disposed in the knife slot. 12. The feed mixer as set forth in claim 9 wherein the spiral flight further comprises at least one brace for reinforcing the spiral flight. 13. The feed mixer as set forth in claim 12 wherein the at least one brace is disposed on the underside of the spiral flight. 14. The feed mixer as set forth in claim 9 wherein the spiral flight further comprises at least one wear plate disposed near the leading edge. 15. The feed mixer as set forth in claim 9 wherein the kicker further comprises a kicker wear plate. 16. The feed mixer as set forth in claim 9 further comprising a second auger disposed in the mixing tub, the second auger operatively coupled to the mixer drive unit. 17. The feed mixer as set forth in claim 16 wherein the mixing tub further comprises at least one baffle for partially segregating the mixing tub into two portions. 18. The feed mixer as set forth in claim 9 further comprising a trailer, the mixing tub mounted on the trailer. 19. The feed mixer as set forth in claim 9 wherein the mixing tub further comprises at least one feed gate that can be opened to dispense mixed feed from the mixing tub when the at least one auger is rotating.
