ENGINE DETAIL
The John Deere 4850, powered by a 7.6L intercooled turbocharged diesel engine, delivers 207.9hp at rated RPM of 2200, making it suitable for heavy-duty agricultural tasks while maintaining efficient operation under load. Its 15:1 compression ratio offers excellent fuel efficiency and torque output, though the smaller oil capacity (21qts) may necessitate more frequent maintenance checks, especially under extended operations. The dry air cleaner is advantageous for dust-prone environments but may require more regular replacement or cleaning to ensure optimal air intake performance.
