ENGINE SPECIFICATIONS
The John Deere 9R 390 features an efficient PowerTech 13.6L diesel engine, which offers superior torque and performance at a rated speed of 2100 rpm. Its wet-sleeve cylinder liners enable easier maintenance and repair, while the advanced aspiration system, including EGR and air-to-air aftercooling, enhances fuel efficiency and reduces emissions to meet Final Tier 4 standards. However, the complexity of its after-treatment system (DOC/SCR) could present maintenance challenges, particularly in high particulate matter environments.

TIRES
The John Deere 9R 390 tractor exhibits a turning radius of 6.035 m (19.8 ft) with Group 47 or 48 tires, allowing for effective maneuverability in confined spaces. This tight turning radius is advantageous in agricultural tasks requiring precision, such as planting or cultivating in tight rows. However, users should consider the impact of tire selection on traction and stability, as larger tires may offer better field performance but could slightly increase turning radius.
