摘要：
A foldable auger having a first and second auger assemblies, each having a respective housing, auger screw and rotation axis. A pivot joins the assemblies, and is configured to permit the second auger assembly to fold relative to the first auger assembly. A first drive coupler is located at an end of the first auger screw and offset from the first axis, and a second drive coupler is located at an end of the second auger screw and offset from the second axis. A drive sleeve is rigidly connected to the end of the second auger screw. The drive sleeve has at least one slot that slidingly receives the second drive coupler. The second drive coupler is movable between a first position in driving connection with the first drive coupler, and a second position not in driving connection with the first drive coupler.
