Abstract:
1. An extended reach power tool apparatus comprising: a powerhead comprising a motor and a casing enclosing the motor; a yoke having a base portion capable of being secured to a pole, and a boss extending in a lateral direction from said yoke, said boss pivotally secured to said powerhead whereby said powerhead is rotatable about said boss relative to said yoke to rotational positions; a locking mechanism releasably connecting said powerhead to said yoke by locking said powerhead to said yoke in a selected one of a plurality of said rotational positions, said locking mechanism being capable of being locked in each of said plurality of said rotational positions and unlocked for allowing rotation of said powerhead relative to said yoke to said rotational positions, wherein a friction brake is disposed between said boss and the casing of said powerhead for inhibiting the free rotation of said powerhead when said locking mechanism is unlocked; and a cutter blade assembly, said cutter blade assembly being connected to said powerhead, said cutter blade assembly being engaged by an output gearing, said output gearing being engagable by and driven by the motor, wherein the cutter blade assembly extends in a longitudinal direction from the powerhead and includes an elongate bar extending in said longitudinal direction and having a plurality of blades extending laterally outward from sides of the elongate bar, the cutter blade assembly further including a longitudinally reciprocating cutter extending in said longitudinal direction and having a plurality of blades extending laterally outward from sides of the reciprocating cutter, said blades of the reciprocating cutter disposed parallel and adjacent to said blades of the elongate bar, wherein said boss comprises an aperture extending axially therethrough in said lateral direction, and power wiring is routed through said aperture in said lateral direction to said powerhead so as to facilitate routing said wiring from a power source through the pole to said powerhead.
