ENGINE DETAIL
The New Holland TJ450, powered by a Cummins QSX 15 engine, delivers robust performance with 450hp and a substantial torque of 1743 lb-ft, ideal for demanding agricultural tasks. Its liquid-cooled system and dual air cleaner enhance efficiency by maintaining optimal operating conditions, although the engine's large displacement (14.9L) may present challenges in fuel consumption and emissions compliance. Notably, the high compression ratio (16.5:1) facilitates better thermal efficiency, making it suitable for heavy-duty applications under continuous high-load conditions.
