Abstract
A harvesting device for separating round root crops, such as potatoes, from soil and other unwanted material. The crop and the soil in which it is growing is uplifted into the harvesting device by the forward movement of the device. The uplifted material is delivered into two conveyors, one positioned above the other and one running at a different speed from the other. The upper conveyor has a series of transverse members, such as fingers and flaps, which break up the uplifted material into discrete portions and these transverse members form with the lower conveyor a series of pockets so that each discrete portion of uplifted material lies in a pocket. The conveyors are inclined and this combined with the differential speed causes the material to be tumbled and the round root crops to roll free of unwanted material.
