ABSTRACT:
A portable mixer has a bin with a number of augers rotatably mounted therein. The augers have forward flights, for conveying roughage feed material, such as hay, in a forward direction, and reverse flights, for conveying the feed materials in an opposite direction. The augers mix feed material introduced into the bin and convey the feed material to a discharge opening. At least one of the augers has a ribbon flighting positioned at an outer peripheral edge of the auger flighting. The ribbon flighting has an outer edge having a continuous saw-tooth cut. The relatively small, closely spaced teeth of the saw-tooth edge cuts the elongated fibrous material, such as hay, without increasing the torque required by the auger. The ribbon flighting is formed from a number of separate, identical ribbon flighting members positioned in series along the outer peripheral edge of the auger flighting.
