Abstract
Auger apparatus comprising a driving power train in which one or two auxiliary powertrain boxes are provided, two auxiliary boxes being used when two or more augers are to be driven, and one auxiliary box being used when only one auger is to be driven. The apparatus as a whole can be substantially shorter and closer to the ground than the apparatus of this type heretofore used, which required less excavating of the ledge adjacent the wall in which drilling is to occur, and makes possible easier transportation.
