ABSTRACT:
An excavator or earth-working device comprising a forked dipper arm, a linkage and an earth-working implement pivotally connected to the forked dipper arm and linkage and articulatable about the free end of the dipper arm. The implement is attached to the dipper arm and linkage of the earth-working device by a so-called "quick-hitch" connection to allow interchange between various earth-working implements. A safety device may also be provided on the "quick-hitch" connection to prevent accidental detachment of the implement from the dipper arm and linkage.
