Abstract:
A lateral plough adapted to be attached to a hitch assembly of a motor vehicle for removing selected segments of an elongated pile of particulate material comprising: a blade having an inner end adapted to be in proximity to said motor vehicle and an outer end adapted to be remote from said vehicle, said blade adapted to swing from an operative position in which its ends are at approximately the same elevation and said blade is in position to push said particulate material forward to an inoperative position in which said outer end is higher than said inner end; a gate pivotally disposed at the outer end of said blade and having an outer edge which swings toward said blade to a closed position in which said outer edge is adjacent to said blade and which swings away from said blade to an open position in which said gate prevents said particulate material pushed by said blade from exiting from the blade as said plough advances; resilient means for biasing said gate open when said blade is in said operative position but being opposed and overcome by the force of gravity when said blade is in said inoperative position thereby allowing said blade to close.
