    摘要： A crumbing mechanism for excavating machines including a mounting assembly for detachable connection to the boom structure of the machine and a crumbing shoe having a boxlike and reinforced bridge construction detachably connected by the mounting assembly to the boom for excavating operations rearwardly of the digging unit of the machine. The mounting assembly includes a selectively adjustable and lockable arrangement for laterally orienting and locking the crumbing shoe in its active position in aligned following relation rearwardly of the machine digging unit, and the mounting assembly and crumbing shoe conjunctively include a selectively adjustable and lockable arrangement for selectively raising or lowering the crumbing shoe into and out of active position.
