Answer:
Potato-Digger
Potato cultivation, especially on large size farms, has got mechanized because; it was not possible to handle the labour intensive operations like sowing and harvesting. Manually harvesting of potatoes requires about 800 man-h/ha, which is quite a labour intensive job. However, potato-digging operation has been mechanized with the introduction of potato diggers. The machine may be manually operated or power operated such as animal-drawn potato digger (Fig. 1), tractor-drawn potato digger (Fig. 2), potato digger shaker and potato digger elevator (Fig. 3). The potato digger elevator consists of a shovel, rod chain conveyor, gearbox and two gauge wheels. The machine digs one or two ridges of potatoes at a time and picks up the soil-potato mass over the rod chain conveyor. Agitating sprocket, of this conveyor oscillates the rod chain and separates the soil. The tubers with no or very little soil drop out on the ground in a row behind the machine, which are later collected manually. These machines are commercially available and are used widely in the northern states of India. Most of these machines are 2 row machines, but 1-row and 2-row both types of diggers are also available. The machine can cover 1.5-3.0 ha/day at forward speed of 2.0-3.0 km/h. Potatoes are easily bruised or skinned but are less susceptible when fully mature than when immature.
