Introduction

Challenger MT685C Row-Crop Tractor

The Challenger MT685C is a high-capacity row-crop tractor produced by AGCO in Beauvais, France, between 2009 and 2010. Designed for large-scale agricultural operations, this model balances significant power with advanced transmission technology to handle heavy-duty field tasks.

Engine and Emissions

The tractor is powered by an AGCO SISU POWER 84CTA 8.4-liter, 6-cylinder turbocharged and intercooled diesel engine. It delivers a rated power of 340 hp at 2200 RPM and a maximum torque of 1136 lb-ft at 1500 RPM. To comply with Interim Tier 4 emission standards, the engine utilizes the e3 selective catalytic reduction (SCR) system, which injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.

Transmission and Driveline

The MT685C features the Dyna-VT continuously-variable transmission (CVT), which provides infinite forward and reverse speeds without the need for traditional gear shifting. This allows the operator to maintain optimal engine speed for specific tasks regardless of ground speed. Power is delivered through a four-wheel-drive system, managed by an electro-hydraulic clutch.

Hydraulics and Hitch

The hydraulic system is a closed-center, load-sensing design capable of a total flow of 46.2 gpm at a pressure of 2,901 psi. It supports between 4 and 6 hydraulic valves for implement control. The rear hitch, categorized as III/IV, offers a lift capacity of 26,460 lbs at the ends, while an optional front hitch provides an additional 11,020 lbs of lift capacity.

Operator Environment

The standard cabin is equipped with integrated heating and air-conditioning systems. Optional enhancements include a heated seat, power-adjustable mirrors, and automatic temperature control to improve operator comfort during prolonged field operation.

Conclusion

The Challenger MT685C is engineered for intensive row-crop applications where high torque and precise speed control are required. Its combination of a high-displacement engine, a continuously-variable transmission, and robust hydraulic capacity makes it a versatile solution for large-scale farming requirements.
