An improved pipeline padding apparatus includes a separator for separating fine material out of spoil which is piled along side an excavation, an elevator for transporting spoil to the separator, a pair of guide projections for guiding spoil into the elevator and a pair of auger type devices for directing spoil from the guiding projections both toward the elevator and in the elevating direction. A conveyor is provided to transport the separated fine portion of the spoil back into the excavation, thereby padding the pipeline. The elevator, guide and augers are pivotally adjustable as a unit with respect to a tracked vehicle, which provides maximum adjustability. In a second embodiment for use in rocky soil, the auger-type devices are eliminated and the guide projections are given a broader, concave inner guide surface.
