Agricultural tractors are widely used to improve field productivity; however, conventional diesel-powered tractors are associated with high exhaust emissions and energy consumption. Hybrid powertrains have been proposed to enhance fuel efficiency and reduce emissions, but most previous studies have focused on simple motor-assist strategies, which have shown limited effectiveness under heavy-duty agricultural operations. In this study, a 1-D powertrain simulation model of a 135 kW class non-regenerative parallel hybrid agricultural tractor was developed using SimulationX, and the power source selection and energy consumption were analyzed under plow tillage conditions. A parallel configuration was implemented in which a diesel engine and an electric motor were connected to a common driveline through independent clutches, allowing mode switching between engine-only and motor-only operation. Model validation results showed that the root mean square error was 0.001 and the p-value was 0.76, confirming the reliability of the simulation model. The hybrid driving simulation results showed that the electric motor was engaged for 15.7% of the total cycle time, and the battery state of charge decreased by approximately 1.09% over a 100 s plowing cycle. The equivalent fuel consumption of the hybrid tractor was 0.592 L for the 100 s cycle, whereas that of the 135 kW diesel tractor baseline was 0.750 L, corresponding to a reduction of 21.1%. A reduction of approximately 27.9% in CO₂ emissions was also estimated for the 100 s plowing cycle based on the decrease in diesel fuel consumption. The results were influenced by assumptions regarding specific fuel consumption and energy unit prices, and the findings demonstrate the potential of hybrid powertrains to improve energy efficiency and reduce operating costs under the specified conditions.
