GROUND WORKING DEVICE |
摘要 |
A ground working device is formed from a sub-frame having a first side and a second side, plural discs mounted for rotation on the sub-frame between the first side and the second side about an axis that extends from the first side to the second side; and a set of scoops mounted on each disc in ground contacting position. The scoops efficiently lift the ground surface material, which falls to the ground in a sorted manner with coarser material on top. A motor is operatively connected to the plural discs for rotating the discs about the axis. Each scoop in each set of scoops has a ground working face that extends transversely to the disc on which the respective scoop is mounted. The scoops each have concave ground contacting surfaces. Each scoop is received in a respective slot in the disc in which t he respective scoop is mounted. The ground working device is mounted on a main frame, which is provided with ground engaging wheels. The sub-frame is retractably mounted on the main frame.
