A swivel connection for quick attachment bracket equipped excavator booms. The swivel connection has a frame that mounts onto a quick attachment bracket on an excavator or backhoe boom, and the frame pivotally mounts a second attachment bracket about a swivel axis. The second attachment bracket is adapted to fit into a frame on an implement that also is connectable to the bracket on the boom. An implement attached to the second bracket this can be pivoted relative to the frame of the swivel connection. A linear hydraulic actuator is used for controlling the pivoting movement of the second bracket relative to the frame. |
