Abstract: An auger device of a snow removal machine in this invention has left and right augers and left and right driving tines mounted on left and right auger shafts, respectively. Each auger has an outer auger blade, an intermediate auger blade and an inner auger blade each mounted at one end on the left or right auger shaft. The outer auger blade and inner auger blade are arranged along a first helical path. The intermediate auger blade is arranged 180° out of phase with the first helical path. The left and right driving tines bite into snow, thereby serving as anchors for preventing lifting of the left and right augers.

Abstract: A snow removal machine has first and second augers mounted on respective auger shafts. Each of the first and second augers has an outer helical auger blade, an intermediate helical auger blade and an inner helical auger blade. The outer helical auger blade and the inner helical auger blade of each of the first and second augers are disposed along a common first helical path and are spaced-apart from one another along a rotational axis of the corresponding auger shaft. The intermediate helical auger blade of each of the first and second augers is disposed along a second helical path angularly shifted substantially 180 degrees with respect to the first helical path.
