Introduction
Challenger MT685D Row-Crop Tractor
The Challenger MT685D is a high-horsepower row-crop tractor manufactured by AGCO in Jackson, Minnesota, USA, between 2011 and 2013. Designed for heavy-duty agricultural operations, it integrates advanced powertrain and hydraulic systems to support demanding field applications.
Engine and Powertrain
The tractor is powered by an 8.4-liter, 6-cylinder turbocharged diesel engine equipped with an air-to-air intercooler and an electronic high-pressure common rail fuel system. It produces a gross power output of 340 hp, with a maximum power rating of 370 hp. The engine utilizes selective catalytic reduction (SCR) for emission control, meeting Interim Tier IV standards. Power is delivered through a Techstar continuously variable transmission (CVT), providing infinite speed control in both forward and reverse directions.
Hydraulics and Hitch
The hydraulic system features a closed-center load-sensing (CCLS) design, providing a total flow of 46 gpm (174.1 lpm) and a system pressure of 2900 psi. It supports 4 to 6 hydraulic valves to manage various implements. The rear hitch is a Category III configuration with a lift capacity of 22,760 lbs, complemented by an optional Category III front hitch capable of lifting 11,000 lbs.
Mechanical and Operator Environment
Built on a 122-inch wheelbase, the MT685D features four-wheel drive with a Quadlink suspension front axle to enhance traction and ride quality. Braking is handled by hydraulic wet disc brakes, and differential locks are electro-hydraulically engaged. The standard cab includes air conditioning, with options for the OptiRide Plus hydraulic cab suspension and AGCOMMAND telematics to improve operator comfort and fleet management.
Conclusion
With its robust 340 hp engine, infinitely variable transmission, and high-capacity hydraulic system, the Challenger MT685D is engineered for large-scale farming operations requiring precision and high tractive force in row-crop environments.
