  • Patent number: 10337168
    Abstract: A trenching assembly used to cut a narrow trench in the ground surface. The trenching assembly comprises an attachment frame connected to a hood assembly via a linkage assembly. The attachment frame may be attached to the rear end of a work machine. A rotatable blade is disposed within a cavity defined by the hood assembly. The hood assembly may rotate about two different axes relative to the linkage assembly, and the linkage assembly may rotate about two different axes relative to the attachment frame. The trenching assembly uses a pair of accumulators to hydraulically rotate the linkage assembly about a horizontal axis relative to the frame in response changes in depth of the ground surface being cut by the blade. The linkage assembly may be hydraulically rotated using the accumulators without input from the operator.
