Potato is cultivated in 130 countries on an area of over 18 million hectares; it annually gives more than 300 million tons of tubers. The share of the Russian Federation accounts is about 11% ... 14% of total production. The resulting potatoes consumed in food, animal feed, technical purposes, seed fund. According to the Ministry of agriculture of Russia, the largest number of potatoes in our country (89 %) is produced in peasant farms and personal farms of citizens, the area of cultivation of which make up about 2.7 million hectares. At such farms for the harvest, they use mainly potatodiggers, followed by selection of crops manually. The use of diggers in small areas of planting is more costefficiently in relation to the harvesting combine. In addition, the parameters requested for ATT to damage potatoes when harvesting with the diggers (3%) are higher than during harvesting by combine harvester (5%). As practice shows, for the use of cleaning units, even under optimal harvesting conditions in the hopper of the combine, there are soil and vegetable impurities. There are many different devices intended to localize the problem. Based on the foregoing, we can conclude that it is necessary to pay considerable attention to the quality of work of excavating working bodies, because it affects the productivity of the functioning of the whole machine. Currently, there are widespread potato aggregates with the receiving part, equipped with side disks, spaced along the edges of the plowshares. The disks cut off the raised layer of soil from between the rows. This entails improving the performance of the potato harvester. The most efficient and economical from the point of view of energy consumption, is the work of passive disks with hooks. The quality of potato harvesters depends on the design and performance of excavating bodies. The proposed design solution for an excavating body increases the productivity of harvesting machines

The mathematical model presented in this article allows you to choose rational values and ranges of design and technological parameters of body separation, as well as their further optimization

In the article we have proposed a program, an object, a methodology and results of field studies of the improved potato digger KTN-2V equipped with the original device for separation intensification

The development of agricultural production inevitably entails an increasing volume of traffic and a turnover of goods. Therefore, the issues of increasing transport efficiency, reducing the price of transportations and improving productivity acquire great importance. In most cases, supersize dump trucks used for the transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have roads with improved surface to each field, which undoubtedly is a significant drawback. Because of the extra movements of harvester dump trucks on the turning strip at the end of the field, it increases expenses of damage and loss of crops and the arrival of heavy machinery in the field leading to soil compaction, that in the end affects the future crop. Transportation of agricultural commodities is most effective when the car arrives directly to the harvester machinery. Such vehicles must have sufficient abilities and capacity of the body comparable with the volume of a combine hopper and has no significant impact on soil sealing. With this method, harvesters do not make extra movements and are not idle. Basic requirements for vehicles used in the harvesting potatoes, are in a more productive use due to increasing the capacity and reducing downtime when loading or unloading and minimizing the level of damage to other tubers. For the transportation of agricultural products there is a different transport technology, which either do not fully meets the requirements of transportation of highly fragile product, or has a significant cost. Therefore, we require a specially equipped vehicle bodies, with a competitive ability in the range acceptable to the Russian Federation. As one of the innovative developments, this article proposes a tipper body of the vehicle for transportation of highly fragile agricultural products. The proposed design solution for the tipper ensures a uniform unloading of transported products from the vehicle body and prevents arching issues
