A rotary cutting machine is provided for cutting vegetable products and the like, such as potatoes, into a plurality of smaller pieces, such as elongated shreds to form hashbrown potatoes. The cutting machine comprises a stationary cylindrical knife housing having about its periphery a plurality of axially extending open slots each lined on one side by a cutting knife. The product is supplied into an impeller mounted for rotation within the knife housing for centrifugally throwing the product into cutting engagement with the cutting knives. The impeller comprises a circular base plate closing one axial end thereof, an annular cover plate defining an enlarged central opening for admission of the product at the opposite axial end thereof, and at least one annular divider plate positioned axially between the base plate and the cover plate, all supported at their peripheries by a plurality of axially extending paddles. A central rotor projects from the base plate along the axis of the impeller and includes radially and axially extending vanes which, during operation, cooperate with the divider plate to divide the product for generally equal flow on opposite sides of the divider plate, and to orient the product with respect to the cutting knives.
