The semi-trailed potato harvester with lateral digging is designed for harvesting potatoes on ridge plantings with row spacing of 70, 75 or 90 cm in potato cultivation zones with a moderate climate. The harvester is aggregated with tractors of 3 drawbar category and easily copes with its tasks on light and medium soils, including light and medium loams.
The maximum permissible slope of the fields for the harvester is no more than 4º. The design of the harvester has an enlarged technological path, consisting of 3 sifting conveyors, and the digging section has a hinged connection with the main frame for copying the relief of the field. These technological solutions provide high productivity of the harvester, which makes potato harvesting economical and efficient.
With PT2 potato harvesting will become a comfortable process, since the harvester has a number of modern technological solutions: the harvester has a haulm separation system, inclined slides of the lower and upper tiers for separating small impurities, bucket and intermediate conveyors for more careful feeding of potatoes from sifting conveyors to the sorting table, which is equipped with platforms for 4 sorters.
The PT2 harvester has an autonomous hydraulic drive system for a number of working bodies with a drive from the tractor power take-off shaft. The hydraulic working bodies are controlled from the tractor cabin using a remote control. A mechanical or combined drive of the harvester's working bodies is also allowed. In this case, the harvester's hydraulic system operates from the tractor's hydraulic system and is connected via quick-connect couplings.
The hopper capacity is 6 tons. To monitor the technological process, a video control system is installed on the harvester. It consists of two video cameras and a monitor located in the tractor cabin.
