A Potato harvester is a type of agricultural machinery designed to assist in the harvesting of potatoes.

OperationEdit

They work by lifting the potatoes using a spade or disc on to a webbed belt where all the loose clay fall out. The potatoes then move back on the harvester on to dolmen rollers and the on to a picking table where a men pick out the stones and the clay. The potatoes then go on to a side elevator and into a trailer or a potato box.

They come in single row or double row, some are self propelled and others are trailed behind tractors.
