ENGINE DETAIL
The AGCO POWER engine in the Challenger MT665E features a robust 8.4L displacement and a turbocharger with air-to-air intercooling, providing efficient power delivery of 290 hp (up to 320 hp max) at 2100 RPM. Its Tier IV emissions compliance with selective catalytic reduction (SCR) technology ensures reduced nitrogen oxide emissions, making it suitable for modern agricultural operations while potentially increasing operational costs due to the need for DEF (diesel exhaust fluid). Key advantages include high torque output for challenging field applications, while the electric starter and 12V system enhance reliability in cold weather starts.

CHALLENGER MT665E ENGINE
The Challenger MT665E features an AGCO POWER 8.4L 6-cylinder diesel engine, providing robust power and fuel efficiency for demanding agricultural tasks. Its substantial 166-gallon fuel tank allows for extended operation without frequent refueling, enhancing productivity on large fields. However, the need for 15.8 gallons of diesel exhaust fluid (DEF) indicates adherence to Tier 4 emissions standards, which may require additional management in remote applications.
