ABSTRACT:
A head shaft breaking tool comprising an elongated hollow shank portion adapted to be slipped over the head shaft. The lower end of the shank portion is provided with a plurality of spaced-apart teeth which are adapted to engage the coupling at the lower end of the head shaft. A cross bar is secured to the shank portion at the upper end thereof and is adapted to receive hold-down bolts extending upwardly from a housing at the upper end of the head shaft to draw the teeth into engagement with the coupling and to prevent rotation of the shank portion as the head shaft is rotated relative to the coupling by means of a pipe wrench or the like.
