Tool Differentially Or Sequentially Lifted At Longitudinally Spaced Points Patents (Class 172/473)
  • Patent number: 11091897
    Abstract: An implement mounting assembly for mounting a work implement to a vehicle is mountable and operable using a retractable cable operatively connected to the vehicle. The implement mounting assembly includes a frame having a work implement support end and a vehicle attachment end, the frame defining a cable routing space, an attachment point to which the cable extending through the cable routing space is attachable, the attachment point being connected at the work implement support end of the frame, and an auto-release cable management assembly disposed longitudinally between the attachment point and the vehicle attachment ends of the frame. The auto-release cable management assembly includes a hook and a gate positioned with respect to the hook to be movable between an open position in which the hook is accessible to the cable and a closed position in which the hook is inaccessible to the cable.

  • Patent number: 4313504
    Abstract: A ripper assembly (10) includes at least two ripper members (16,18) mounted in tandem relationship and adapted for connection to a vehicle (14). A linkage assembly (20) interconnects the ripper members. A hydraulic cylinder (44) is operable to raise and lower the linkage assembly (20) so that the leading ripper member (16) penetrates the ground first and thereafter the trailing ripper member (18) penetrates the ground, vertically below the leading ripper member. The ripper assembly insures efficient ground penetration and a self-cleaning function in comparison with conventional rippers of the multiple-tooth type.
