Comparative Analysis of Technical; Economic and Operational Properties of Belarus 2122 and Zoomlion Pl2304

In recent years; various types of agricultural machinery; particularly Chinese-manufactured tractors; have entered the Russian market. Assessing their operational properties requires statistical data on reliability; theoretical and field studies; as well as certification tests conducted at state machine-testing stations. ( Research purpose ) To analyze the Russian agricultural machinery market; including Chinese manufacturers; and assess the technical; economic; and operational properties of tractors based on engine speed characteristics; to evaluate the impact of the wheel contact area on traction tangential force and overall traction performance. ( Materials and methods ) Building on previous theoretical studies; a comparative analysis of the operational properties of Chinese- and Belarusian-manufactured tractors was conducted. Field tests were carried out to evaluate the operational properties of the Belarus 2122.3 and Zoomlion PL2304 tractors; in combination with the IMT 616.16 cultivator. The research employed a combination of computational; structural-design; and economic-mathematical methods; as well as comparison; measurement; and descriptive techniques. ( Results and discussion ) The operational characteristics of the tractor-implement units and the influence of engine speed characteristics on their performance were determined. Additionally; the effect of wheel size on the realization of tractor tractive properties was examined. Comparative calculations provided insights into tractor efficiency. ( Conclusions ) The technical and economic indicators of the Zoomlion PL2304 tractor; such as operating weight; engine power; energy saturation; ballast weight; specific fuel consumption; and gearbox working range; contribute to the more efficient utilization of key operational properties; particularly productivity and fuel consumption.
