Comparative characteristics of undercarriage systems as criteria for selecting a power tool for risky farming zones

Abstract

The basis of modern machine and tractor fleet of industrial and agricultural tractors are power vehicles with caterpillar and wheeled undercarriage systems of various design. The article considers the summary parametric and factorial characteristics of wheeled and tracked power vehicles used in field and transport works under the conditions of the Amur region. The criteria of formation of their traction and traction properties are analysed, the ways of slipping reduction, reduction of vertical load of machine-tractor unit on the soil and application of agricultural machinery in the period of overwatering are given. The results of research on the application of mobile energy means in conditions of overwatering in the cultivation of agricultural crops, where their main advantages and disadvantages are reflected, the directions of choice of energy means for application in agricultural production technologies in conditions of weak bearing capacity of soils are substantiated. It is established that the use of tracked energy means having high traction and traction properties, when they are aggregated with wide-catch machines in the fields of the region, will be more effective in the periods of work, when there is a significant precipitation. At the same time, wheeled energy means will also be in demand in the natural-climatic conditions of the Amur region as the most universal means, structurally suitable for performing the majority of agricultural field operations as a part of tractor-transport aggregate. In this regard, the expediency of equipping the production-industrial complex and means of mechanisation of farms and agricultural enterprises of the region with power vehicles with different undercarriage systems in accordance with the used and scientifically substantiated regional system of machines and technologies is substantiated.
