Development and performance evaluation of a PTO-based power assist system to improve traction force for electric tractors.

ABSTRACT: Electrification of agricultural machinery is crucial for meeting environmental regulations, with electric tractors being a prime example. However, insufficient power during high-load operations, such as plow tillage, limits the field applicability of conventional electric tractors. To address this, we propose and evaluate a Power Take-Off (PTO)-based power-assist system to supplement the traction power. Three powertrain configurations were modeled and compared: (i) a baseline dual-motor coupling powertrain (DMCP), (ii) a speed-coupling DMCP with power-assist system, and (iii) a mixed-coupling DMCP with power-assist system. The performance was evaluated under measured plow tillage conditions, focusing on traction force, travel speed, and energy consumption, with the latter assessed using an
