Potato harvester

A potato harvester is a harvester for harvesting potatoes. The term is also used for modern potato harvesters.

The potato harvester arrived in the mid to late 19th century, they represented a good first step in the mechanization of potato construction dar. Previously, the potatoes had been excavated with spade or fork or chopped with the karst from the dam out of hand. As an alternative to manual labor, there was the potato digger, a special plow for the potato harvest.

Centrifugal harvester

The first centrifugal harvester ( also potato witch) was developed by the British Hanson and Coleman 1852. The spin -digger clears the potatoes with a flat, potato dam easy lifting and fracturing crowd, and a subsequent, perpendicular to the multitude, and thus to the dam direction attached Schleuderradstern. This circles perpendicular to the dam and hurls through the forks or tines attached to it to the ground and potato mixture in a shallow layer of the embankment around 2 to 3 m to the side so that the reader potato potato tubers can easily find and collect. Thus, the tubers are not damaged, it was important in the design of centrifugal harvester that the forks or tines of the centrifugal wheel take less striking, but rather sweeping on the dam. The drive of the impeller wheel is usually carried out by a driven by the wheels of the harvester angle transmission in some embodiments, but also by the power take-off shaft of a tractor.

Siebroder

Unlike the centrifugal harvester of Siebroder (also called vibration harvester or Siebkettenroder ) the potatoes does not spin easily from the dam out, but the entire dam, or even more, with the potatoes is lifted by means of a horizontal band on a sieve. Through this sieve the soil is sieved and the potatoes remain in a row behind the machine are. In some variants of this form of harvesters, the screen was moved back and forth via the PTO. Siebroder can be used except for harvesting potatoes also during harvesting of root vegetables such as carrots and celery.
