  • Patent number: 5987864
    Abstract: A front mounted rake includes a primary support, a first arm and a second arm. Tine wheels are mounted each of the arms. The first end of each arm is secured for pivotal movement about both a substantially vertical axis and about a substantially horizontal axis to the primary support. The second end of each arm is supported by ground engaging wheels. A brace maintains the relative lateral spacing of the arms. The pivotal movement of the second arm about the substantially horizontal axis is independent of the pivotal movement of the first arm about the substantially horizontal axis thereby permitting the first arm and the second arm to independently raise and lower as the ground engaging wheels travel over ground contours.
