Functional evaluation of tractors of traction class 4.0

Abstract

The optimal choice of purchased equipment based on its functional characteristics is an important task for modern agricultural enterprises. In order to select the optimal tractor model, the cost and types of work performed were compared with three tractors of traction class 4.0: Kirovets K-5, BTZ 254-K, and DEUTZ-FAHR6230 TTV. To determine the differences through the examination, the authors used a methodology of comparing tractor models, taking into account indicators of technological versatility, agrotechnical properties, potential (expected) productivity and cost of performing technological operations. They also determined an indicator of the technological level of tractors. The assessment results showed the applicability of all models for plowing and harvesting operations, as well as for working with mounted combined machines. However, the models were considered unsuitable for inter-row cultivation. As compared with domestic counterparts, the DEUTZ-FAHR6230 TTV can reach higher speeds and higher performance. However, the technological level of Kirovets K-5 and BTZ 254-K tractors has the same value of 0.72 and surpasses the imported analog DEUTZ-FAHR6230 TTV, which has an indicator of 0.69. Taking into account the functional characteristics and cost of tractors, it is profitable for enterprises to purchase domestic equipment.
