ABSTRACT:
The stabilizer apparatus for a power head attachment for rotationally powered tools in which a housing supports a stabilizer apparatus including a stabilizer collar rotatable to selected positions relative to the input shaft of the head attachment and a stabilizer arm pivotally mounted on the collar for movement to selected angular positions relative to the axis of the input shaft between a plurality of locked positions and a single unlocked position. In the unlocked position of the arm, the collar can be rotated to various circumferential positions and in each one of the positions the stabilizer arm can be located at a selected one of multiple angular positions which also lock the arm and collar in a fixed position making possible many combinations of positions of the stabilizer arm relative to the power head of the tool.
