  • Patent number: 4688969
    Abstract: A ground rod installation device having an auger fixedly mounted on the lower end of an elongated drive shaft. A pilot drill projects downwardly from the lower end of the auger. The shaft, auger, and pilot drill have aligned axial passages into which the ground rod is inserted. A releasable fastener then secures the ground rod in place inside the shaft. The shaft is rotated in one direction, thereby causing the auger to draw the shaft into the ground. After the releasable fastener has released the ground rod from the shaft, the shaft is rotated in the opposite direction, thereby withdrawing the shaft from the ground while allowing the ground rod to fall through the passages in the auger and pilot drill and remain in the ground.
