ENGINE DETAIL

The Challenger MT665C tractor's AGCO SISU POWER 84CTA engine, with a 8.4L displacement and 290hp (with a maximum of 320hp), is designed for high-performance agricultural applications, utilizing an electronic high-pressure common rail fuel system for efficiency. The implementation of a selective catalytic reduction (SCR) system, alongside optional integrated exhaust gas recirculation (IEGR), helps achieve compliance with Interim Tier 4 emissions regulations, though it requires regular maintenance and urea refills for the SCR system. With a robust torque rating of 1033 lb-ft at a lower RPM of 1500, this tractor excels in heavy-duty applications such as plowing or towing, making it ideal for larger farming operations.
