Investigation of technological properties of wide span tractors for controlled traffic farming

Abstract

Practical use of wide span tractors (vehicles) for controlled traffic farming needs further motivation of the principles of their automatic steering, allowing maximum reduction of area losses of the field under the engineering zone at least 1.5 times. The use of contemporary wide span tractors (vehicles) with a track width more than 7.5 m allows reaching a value of the area losses of the field under the engineering zone not more than 5…6 %, which is quite acceptable. The presented brands of such tractors are provided with various technological equipment and means of automation, the technological significance of which can be estimated only by means of objective assessment methods. The developed equation for the estimation of the potential efficiency of the wide span tractors makes it possible to conduct analysis of the degree of impact upon them made by their design parameters and indicators of technical characteristics. Estimation of the degree of potential efficiency, which the contemporary wide span tractors should have, showed that the result exceeds the potential efficiency of the conventional machine and tractor aggregates by 1.5-2 times.
