An apparatus for separation of agricultural products, which are normally joined to each other by a stem or the like, includes a conveyor for carrying agricultural products; a plurality of cutting modules positioned above the conveyor, each having a plurality of blades spaced along a rotating shaft, the shafts of the respective cutting modules being parallel to one another and orthogonal to the direction of movement of the conveyor; a positioning ramp associated with each blade; and a mechanism for simultaneously adjusting the height of the cutting modules above the conveyor to thereby enable the apparatus to effectively process agricultural products of varying sizes.
