61 therefore articulation of the thumb 93 can be easily controlled by actuator 27 separately from articulation of the implement 61 as controlled by actuator 25 moreover since attachment of the dipper stick 13 to the coupler 33 does not require separation of pin 81 from the implement 61 and thumb 93 it is possible to attach the implement 61 without dismantling the linkage between the thumb 93 and the implement 61 significantly removal of implement 61 and thumb 93 consists of disconnecting progressive link 38 and removal of pin 87 by means of a quick coupling device at that time actuator 25 may be retracted this allows easy removal of the combined attachment 61 and 93 while a specific embodiment of the invention using a particular dipper stick 13 and pin arrangement 81 83 87 have been described it is possible to implement the invention with different configurations of pins and slots it is also possible to retain an implement on a carrier by fasteners other than the pin and bolt arrangement 87 89 for example the implement 61 can be directly bolted to the carrier after slots 71 74 are engaged since actuator 27 is separately operable it is possible to include a quick disconnect for connecting the opposing element thumb 93 in fig3 to its actuator 27 as mentioned it is intended that a wide variety.
