ABSTRACT:
An auger assembly for transporting seed, fertilizer or other particulate material. The assembly provides an auger within a stationary tube; the auger is mounted to allow free axial movement between adjustable limits. In the normal augering position, the auger extends beyond the tube into the particulate material. Should the particulate material become packed or jammed, preventing the auger from turning, the auger can be driven in reverse, causing it to unscrew itself up into the tube and allowing the auger to then take a fresh bite at the particulate material.
