The role of transport in agricultural production is significant. It is the connecting link in the technological chain of the agro-industrial complex (of the APC). On-farm transport in the APC together with cars and tractor transport are widely used. The rationality of the use of wheeled tractors for farm transport substantiates the possibility of their movement on asphalt and on dirt roads. The specific gravity of the tractor transport in the domestic agriculture is 22-27% of the total volume of transport and 50-60% of the volume of farm traffic. A high level of use of tractor transport has been observed in the countries of Western Europe and the USA. In the farms of leading countries of Western Europe (Germany, Italy, France, etc.) about 70- 90% on-farm transport of agricultural goods is done by tractor transport. Tractor transport in a live environment is running on roads with varying terrain, a wavy profile cover, on soils with different hardness and humidity. When driving vehicles at high speeds, the trailer is wobbling from side to side, constantly accompanying tractor transport during its operation. As a result, it is bad for propulsion, transmission, and it deteriorates the dynamic performance properties of equipment, working conditions of the operator. To reduce the amplitude of oscillations of the trailer, the operator is forced to work strenuously with the steering wheel or to slow down the speed, which in turn affects operator fatigue, as well as the performance and maneuverability of the vehicle. Thus, advanced technologies in electronics, sensor technology and software will determine the nature of agro-technical innovations and will lead to increased automation of business processes in crop production with the aim to organize the work more effectively, efficiently, accurately, environmentally friendly and economically feasible. When working with intelligent technologies, understanding the development of high-tech, precision engineering requires a revision to the personnel policy and education in agriculture, which should be based on the relevant organization of farms and their proper new type engineering solutions

The article presents the scheme-constructive solution for the separating working organ of the potato harvester, that allows to improve separation efficiency of root crops off the stems tops of vegetable and plant residues in difficult harvesting conditions, as well as reducing the amount of damage to tubers

Due to the deterioration of the ecological situation in the world, population tends to eat organically grown foods that are grown either without or with minimal use of chemicals. The development of agriculture in this direction leads ultimately to organic agriculture. To improve the competitiveness of this direction, we need more effective agricultural machines, especially in the last phase of cultivation, namely at the stage of harvesting. One of the most difficult scientific and technical problems with the mechanical harvesting of potatoes is not letting vegetable impurities and tops to fall down in the hopper with the potato tubers, which among other things will improve operational efficiency technology. The article reviewed the various methods for removing the tops, as well as their advantages and disadvantages. The article makes a conclusion about the need for potato top separators in harvesting machines. We have also considered a promising device for removing haulm, a conveyor with flexible fingers on the bars and the clamping beater. Тhe most short-lived structural element of the device for removing haulm, reducing reliability of the device, is flexible fingers mounted on rods. We have proposed to use polyurethane as a material for manufacturing flexible fingers

This article deals with the present level of harvesting and transport operations in the production of potatoes and methods of improving the operational and technological parameters of machines with which they are carried out by introducing into their design of innovative devices

In the article, the questions of increasing productivity exploitation of vehicles and mobile agricultural technology by developing universal vehicles for inner transportations of agricultural products have been reviewed

Potatoes in our country are one of the most cultivated cultures in agriculture. The most time-consuming process in the production of potatoes is harvesting. Currently for potato harvesting potato harvesters or diggers are used. Existing machines are not sufficiently well-behaved in adverse operating conditions such as the high and low humidity. Quality of work of the units and devices of potato harvesters depends on the digging working parts. In the process of potato harvesting up to 1000 tons of heaps from 1 hectare go through the units of the machine, which includes plant residues and dense soil out of row spacing. To eliminate or reduce the impact of this lack, on either side of the coulter we set cutting discs which prevent ingress of heaps out of row spacing. However, due to the imperfections of the design they are slipping during operation what causes accumulation and enhancing traction resistance. Based on these facts, the work on improving the digging working parts in the actual and future challenges for the country's agriculture
