1. An excavator tool adapted to be secured to an excavator boom, the excavator tool comprising:
(a) a main tool assembly including:
i. a main tool framework;
ii. a spaced apart pair of connection flanges fixedly coupled to the main tool framework; and
iii. a structural tubular casing fixedly coupled to the spaced apart pair of connection flanges;
(b) a drive axle housed within the structural tubular casing and extending outwardly from each end of the structural tubular casing;
(c) a rotary actuator housed within the structural tubular casing and adapted to provide a rotational drive motion to the drive axle; and
(d) a working tool framework having a pair of working arms, each working arm being fixedly coupled to the drive axle at a position outward from the structural tubular casing, the pair of working arms being spaced apart at the drive axle by a distance that is not greater than a maximum width of the main tool framework.
