An overburden removal system receives, comminutes and transports excavated material. Two laterally spaced apart pivotal crawler track assemblies () () and rearwardly spaced crawler track assembly () provide for advancement using serpentine turns. Two opposing feed assemblies () () each have a feed hopper () () and an elongately movable feed conveyor () () for feeding a medial rock crusher () carrying two parallel oppositely rotatable rock crushing drums (). Discharge conveyor () carries comminuted material from rock crusher () to telescoping conveyor () pivotally attached to rearward edge () of mobile sizer () for transfer to a mobile hopper () supported by bridge conveyor () operatively communicating with a movable conveyor (). Automated control system () using GPS technology controls movement of mobile sizer (), telescoping conveyor () and bridge conveyor () to maintain a continuously operative interconnection therebetween while moving and while stationary for continuous operation.
