A pitter for removing whole or half pits from clingstone drupe halves in which relative movement between a drupe half and a member on the pitter toward each other, from a spaced position, is effected, until said member engages the planar surface of the drupe half around the exposed pit, and thereafter, continued movement in the same direction automatically actuates a mechanism that causes pit engaging elements on said member to engage the side of the pit adhered to the pit cavity, and to apply yieldable outward pressure on the pit to tension the fibers holding the pit in said pit cavity. At the same time such pressure is applied said elements are revolved relative to the pit to break the tensioned fibers and to rotate the pit relative to the peach half when adhesion is weakened, and said member and elements are thereafter automatically actuated to withdraw and to release the detached pit from the half, and to restore the member to its spaced position preparatory to another pitting operation.
