Abstract: A harvester for root crops such as beets is provided which preferably provides improved flow of root crops from a lifting assembly, along a plurality of transfer assemblies, and to a holding tank or a separate loading vehicle. Each transfer assembly includes a transfer surface, typically a conveyor or roller, for the downstream movement of harvested root crops. At least one of the transfer assemblies includes a movable stagnation reduction member mounted for rotation above the associated transfer surface. The movable member is typically positioned at a transition region of the flowpath in order to provide a “moving wall” that contacts harvested root crops to urge them downstream and prevent stagnation at the transition region. The movable member may be driven by any of a number of possible mechanisms or undriven and rotated by contact with the flow of crops.
