ABSTRACT:
A control system for a trimmer head assembly includes a first arm including a first mowing device, a first cylinder connected to the first arm, a source of fluid in selective communication with the first cylinder via a fluid line, and an accumulator in selective communication with the first cylinder when the first cylinder is not in communication with the source of fluid. The accumulator is adapted to receive fluid from the first cylinder when an external force is applied to the first arm and to deliver fluid to the first cylinder when the external force has been removed from the first arm.
