BUILDING A DRIVE TOOL STRING

Selecting the correct Kelly Bar Adapter is key to building a successful drive string. Follow these two easy steps:

1) Remove the auger from the digger and carefully measure the X and Y dimensions of the Kelly bar.

2) Match the shape of the Kelly bar and the X and Y dimensions with the Kelly Bar Adapter table. The Y dimen sion on the Kelly Bar Adapter must be equal to or greater than the Y dimension on the Kelly bar itself.
