ABSTRACT:
A relatively short tunnel shield is connected to a light weight floating arm including a first tube telescopingly received within a second tube. Multiple holes in the double tube arm allow optimum positioning of the shield relative to a ground engaging element such as a single wide sweep to match different operating speeds without need of a longer and heavier shield. The second tube is pivotally connected to the rig by double plate mounting assembly to minimize side-to-side play. Slots in the double plate mounting assembly provide infinitely adjustable down stop for precision shield height control. The arm can be raised, and by installing a cross pin in the mounting assembly, the shield is maintained in a storage position out of the way of more mature crops.
