New technical solutions for modernization of designs of four-row clonal potato planter

The results of modernization of clonal potato planters are presented to improve the mechanism for adjusting the pitch of planting, which determines the distance between tubers in a row and the density of planting of germinated tubers regardless of the operating conditions of planters and soil-climatic zones of potato cultivation. The design of a variable-speed unit for stepless adjustment of the step and planting density is proposed.

A Systematic Approach for the Agricultural Sector

A rigorous description of the systematic approach to the most developed ergatic systems and a unified procedure for the study and construction of systems based on general systemic principles and postulates are presented. The adaptation of the general procedure for the systemic approach for the agricultural sector and its application to the analysis of the implemented programs of digitalization of agriculture are provided.

Comparative Indicators of Grain Transportation When Unloading Combine Harvesters at the the Field Edge

Base don theresults of comparative experience in production conditions, the indicators of grain transportation by trucks were determined when unloading combine harvesters at the field edge.

Method for Determining the Pressure of a Pneumatic Wheel on the Soil

A method for determining the pressure of a pneumatic wheel on the soil is proposed. The method consists in measuring the magnitude of the vertical acceleration of the axles of a self-propelled vehicle, its speed and air pressure in the tire. The research results allow the developers of vehicles fitted with pneumatic wheels to choose rational characteristics of tires and optimal parameters of the oscillatory system of wheeled tractors, which help to reduce soil compaction.
