ENGINE SPECIFICATIONS

The John Deere 6R 120 features a robust 4.5L turbocharged diesel engine capable of delivering efficient performance at a rated speed of 2100 rpm. Its advanced aspiration system, which includes variable geometry for improved air intake, and integrated exhaust after-treatment, ensures compliance with Final Tier 4 emissions regulations while optimizing fuel efficiency. However, the complexity of the DOC/DPF/SCR after-treatment may pose maintenance challenges, requiring regular monitoring to ensure optimal operation in demanding agricultural scenarios.

ENGINE PERFORMANCE

The John Deere 6R 120 tractor features a robust 97 kW (130 hp) max engine power with Intelligent Power Management (IPM) providing an additional 20 hp for transport or PTO tasks, enhancing versatility in power-intensive applications. With peak torque of 562 Nm at 1600 rpm, it exhibits strong pulling capability, benefiting tasks like tilling or heavy towing. However, the 40% PTO torque rise means careful management is required to prevent potential overloading during high-demand operations, making it essential for operators to match implement sizes and weights appropriately.
