ENGINE SPECIFICATIONS
The John Deere 9RT 490 features a robust 13.6L in-line six engine, designed for high torque and efficiency with a rated speed of 2100 rpm, ideal for heavy-duty agricultural operations. Its advanced emissions system incorporating DOC and SCR ensures compliance with Final Tier 4 standards while maintaining performance through cooled EGR and a wastegated turbocharger. The wet-sleeve cylinder liners facilitate easier engine overhauls, providing a maintenance advantage, though they may introduce complexity in terms of sealing and cooling management.

ENGINE PERFORMANCE
The John Deere 9RT 490 tractor features a robust 490hp engine with a peak torque of 2262Nm at 1550 rpm, ideal for heavy-duty tasks requiring significant pulling force. It offers a 10% power boost, allowing for temporary increases in engine output, which can be advantageous in demanding field applications. However, while the PTO power of 335hp is strong, operators must ensure that the implements match the tractor's capabilities to avoid potential overloading or performance issues.
