  • Patent number: 11839170
    Abstract: A working machine coupler device includes a top linkage, a lower linkage, a detachable frame including a second upper coupler to be coupled to a first upper coupler, and a second lower coupler to be coupled to a first lower coupler, and a top linkage controller. The second upper coupler is coupled to the first upper coupler when the lower linkage is pivoted upward, and the first lower coupler moves toward and be coupled to the second lower coupler when a front portion of the working machine is moved upward, and the top linkage controller regulates the stretching and shortening of the top linkage to hold the detachable frame inclining backward, and allows the top linkage to be shortened until the working machine takes a working posture after the lower linkage is pivoted downward from a state where the front portion of the working machine is lifted.
