ENGINE SPECIFICATIONS
The John Deere 8RT 310 features a robust 9.0 L PowerTech PVS diesel engine, optimized for high performance with a single variable geometry turbocharger, enhancing efficiency at rated speeds of 2100 rpm. Its wet-sleeve cylinder liners facilitate easier maintenance and repair, while meeting Final Tier 4 emission standards through a comprehensive after-treatment system comprising DOC, DPF, and SCR, ensuring compliance and reduced environmental impact. A potential challenge is the complexity of the after-treatment system, which may require careful monitoring and maintenance to avoid downtime.
