ABSTRACT:
A mounting bracket for mounting a working device to a boom of a carrier includes a base, flanges for attaching the bracket to the boom, and ears for attaching the working device to the bracket. The ears each define a hole for pivotally coupling the working device thereto for free pivotal movement about a single axis to alleviate the generation of excessive side forces. The bracket further includes stops to limit the free angular movement so that the working device can be oriented at an inclination and so that it may be used to pry pieces of the worked material.
