ABSTRACT:
Apparatus and method are provided for reclaiming strip mined land. The apparatus generally comprises a leading tractor and a trailing tractor and an elongated adjustable side casting blade angularly disposed between and connected to the tractors. Control of both tractors and blade adjustment is carried out by an operator on the leading tractor. The method generally comprises the steps of driving the apparatus along a spoil bank crest near one side thereof in one direction to make one pass to effect side casting of material down one repose slope of the spoil bank and then driving the apparatus along the spoil bank crest near the other side thereof in the opposite direction to make another pass to effect side casting of material down the other repose slope of the spoil bank. Two such passes constitute one complete cycle and blade angle; blade tilt and depth of cut are changed for each pass.
