20140130275 | Rotary Brush Turf Sweeper - A rotary brush turf sweeper includes a frame with a first and second brush carriage supporting a first and second rotary brush. The brush carriages include a first and second carriage bar extending lengthwise along the first and second rotary brush. The brush carriages pivotably attach to the frame by a mounting point on opposing ends of the first brush carriage, allowing the brush carriages to rotate about the attachment point. A brush height adjustment mechanism joins the carriage bars with an electronic actuator. The electronic actuator may be remotely operated to adjust the height of the rotary brushes from a work surface and elevate them so as not to touch the work surface. A first and second drive mechanism transfers rotational force from a pair of drive wheels, so that the rotary brushes always rotate as the device is towed by a vehicle. | 05-15-2014 |
