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.
