Abstract
A first work tool arm is rotatably attached to a frame or reference structure, a second work tool arm rotatably attached to the first work tool arm, and a work tool attached to an end of the second work tool arm. An actuator and a spring are each rotatably attached to the second work tool arm and configured such that separate movement of the first work tool arm relative to the frame or reference structure and movement of the second work tool arm and work tool relative to the first work tool arm are achieved with actuation of the actuator.
