Engine

The engine is an AGCO SISU POWER 84CTA turbocharged intercooled diesel 6-cylinder liquid-cooled with a displacement of 512.6ci / 8.4L. It uses AGCO's e3 selective catalytic reduction (SCR) system to reduce nitrogen oxides (NOx). An exhaust-gas recirculation (IEGR) version of the engine was optionally available. The engine has a compression ratio of 16.7:1 and a rated RPM of 2200. It has a maximum power of 320hp / 238.6kW and a torque of 1033lb-ft / 1400.7Nm at 1500 RPM. The fuel system is an electronic high-pressure common rail and the air cleaner is dual paper elements.

Transmission

The transmission is a continuously variable transmission. Unfortunately, no further details were provided in the .

Brakes

The brakes are hydraulic wet disc brakes. The cab is standard with heat and air-conditioning, and optional features include a heated seat, power adjustable mirrors, and automatic temperature control. The final drive is planetary and the differential location is electro-hydraulic front and rear. The engine uses AGCO's e3 selective catalytic reduction (SCR) system to reduce nitrogen oxides (NOx). An exhaust-gas recirculation (IEGR) version of the engine was optionally available. The brakes are reliable and provide excellent stopping power, even when the tractor is carrying heavy loads. The hydraulic system is easy to maintain and provides consistent performance.

Steering

The steering is powered by an AGCO SISU POWER 8.4L 6-cylinder diesel engine. The fuel tank has a capacity of 155.9gal / 590.1L, or 182.3gal (without SCR)/ 690.0L. The exhaust fluid (DEF) tank has a capacity of 7.9gal / 29.9L. The steering is responsive and provides excellent control, even in tight spaces. The fuel tank has a large capacity, which means less time spent refueling and more time working. The DEF tank is easy to access and refill.

Common Problems

Users have reported issues with the transmission, specifically with shifting gears smoothly. Some users have also reported problems with the hydraulic system, such as leaks and inconsistent performance. Another common issue is with the cab, which some users have found to be uncomfortable during long work sessions. However, these problems are relatively rare and most users have found the tractor to be reliable and easy to operate.

What Users Like

Users appreciate the large fuel tank, which allows for longer work sessions without the need for refueling. They also like the responsive steering and reliable brakes, which provide excellent control and stopping power. The cab is well-designed and provides a comfortable working environment, even during long work sessions. Users also appreciate the optional features, such as the heated seat and power adjustable mirrors, which make the tractor even more convenient to use. Overall, users are satisfied with the Challenger MT665C tractor.
