ABSTRACT:
A hedge trimmer having a hedge trimmer housing, a motor disposed in the hedge trimmer housing and a drive assembly associated with the motor. The drive assembly includes a first housing, a first gear connected to the rotatable drive shaft of the motor, a second housing, a second gear associated with the second housing, the second gear being in contact with the first gear so that the second gear rotates when the first gear rotates, and a support connector for causing the first and second housings to maintain a fixed positional relationship to ensure that the first and second gears remain in contact. The hedge trimmer also includes a first cutting blade operatively coupled to the second gear so that the first cutting blade reciprocates when the second gear rotates and a second cutting blade movable relative to the first cutting blade. The hedge trimmer may also include a gear-travel limit member to prevent any substantial misalignment of the second gear with respect to the first gear.
