Pure electric tractors face challenges in complex operating conditions, including the excessive peak motor torque caused by frequent start–stop cycles and insufficient energy utilization. To address these issues, this study proposes a hydraulic–electric hybrid drive system for tractor traveling systems which is based on range-extended architecture. By combining high-torque characteristics of hydraulic with high control precision motors, dual-power coupling model was constructed. A logic-threshold-based mode division strategy hierarchical braking recovery mechanism were developed. The dynamics efficiency during plowing transport operations thoroughly analyzed. simulation results demonstrate that while maintaining its acceleration performance, proposed achieves 18.8% 35.7% reductions operations, respectively. Its improved to 48.3% 66.4% two scenarios; 18.5% 25.7% overall consumption seen.
