The properties of machine-tractor unit (MTU) regarding soil preparation with bed ridging

Abstract

BACKGROUND: One of the main criteria for assessment of work performance is productivity. It depends on a number of indicators: towing resistance, optimal use of energy, used technical equipment, the adaptability of the equipment to the operation conditions, etc. Experimental studies are required in order to establish the patterns of influence of these indicators on work efficiency. AIMS: Carrying out theoretical calculations and practical observations on the process of bed ridging for potatoes, assessment of the unit assembly for the technological process performing and the using of the unit. METHODS: Field tests of a machine-tractor unit with subsequent result processing using the Microsoft Office applications. RESULTS: Recommendations are given for practical use in the unit formation depending on velocity and operation width of the unit for various values of specific resistance. CONCLUSIONS: The practical value of the study lies in the opportunity of using the proposed patterns for optimization the machine-tractor unit assembly according to operation conditions, selection of power unit, development of combined machines and units. © Eco-Vector, 2023.
