ENGINE DETAIL
The John Deere 7280R features a robust PowerTech PVX engine with 280 hp, providing a solid balance between power and fuel efficiency, particularly beneficial for heavy-duty agricultural tasks. Its Tier 4A emissions compliance, aided by EGR technology, ensures it meets regulatory standards while optimizing performance; however, this may require additional maintenance to keep the EGR system functionally effective. With a significant displacement of 9.0 L and a high compression ratio of 16:1, the tractor can handle demanding workloads, but potential users should be aware of the complexities involved with high-pressure common rail systems and their servicing.
