Po-ta′to-dig′ger.
（Husbandry.) An implement for digging potatoes from the row or hills, and depositing them on the surface of the ground or in a box on the machine. Fig. 3916 is supported on a wheel, and has a grating or bars which lift the tubers, sift the earth from among them, and drop them on the surface of the ground. Fig. 3917 is a more complicated implement, which has a pair of side plows g g, a middle plow G with a large wide share which slips under the hill of tubers and lifts them: they are then pushed back on the grating, which allows the dirt to fall through, and the tubers drop off the end of the grating. In Fig. 3918, the potatoes, after lifting, are carried over the longitudinally barred screen, and then divested of the earth upon the rotating-screen. The cams near the fore end regulate [1776] the inclination of the scraper at the fore end of the fixed screen.
