Abstract: A machine is disclosed which is capable of cutting solid pieces of potato from potato halves. A potato half (42) is supported in the cup (28) of a potato holder (18) beneath a plate (60). The plate (60) slides across the flat surface of the potato half to restrain it from movement, and while this happens a curved blade (88) moves into the potato half through a slot (64) in the plate (60) to cut out a solid piece (b 116) from the potato half (42). The depth to which the blade (88) penetrates the potato as it sweeps through it is controlled by a cam (100).
