ABSTRACT:
An improved blade assembly for moving beneath the surface of the ground to engage and lift a subsurface root crop upwardly and rearwardly when moved along a forward path by a harvesting implement. The assembly includes an elongated blade that is held transverse to the forward direction of harvester travel. The blade is mounted to a framework for oscillational movement about a first horizontal axis and a second axis perpendicular to the horizontal axis. A power source operates the blade to oscillate about these axes in continuous cycles. Each cycle of blade movement includes a forward and downward stroke and an upward and rearward stroke. This movement occurs rearward of and below the horizontal pivot axis for the blade.
