THEORETICAL PREREQUISITES FOR SYSTEMATIZATION OF STANDARD SIZES OF MINI TRACTORS
Abstract
This article presents the results of the analysis of technical characteristics of modern mini tractors. A mini tractor is a power device which is also the most popular equipment for farms, private farming, horticulture and greenhouse farming in modern conditions. The study showed that constructive schemes of machines are constantly improved with the changing of their subsystems. Accordingly, there are some relationships between the parameters of mini tractors.
It is the relationship between the functional purpose and the operating parameters. The relationship between design parameters and design and operating parameters is the basis for their systematization in order to classify models of mini tractors. It is also the basis for their typification in order to establish optimal parameters in the design process and the choice of functional purpose. It was put the concept to simplify the systematization process forward regarding the possibility of choosing one significant parameter that determines the size and functionality of the tractor. Changing a significant parameter affects the main design, technical and operational parameters. It was recommended to take the indicator of the structural weight of the tractor as a significant.
