Introduction
Challenger MT645C: A High-Performance Row-Crop Tractor
The Challenger MT645C is a row-crop tractor produced between 2009 and 2010 in Beauvais, France. As part of the AGCO group, this machine was designed to provide significant power and versatility for large-scale agricultural operations, featuring advanced emission control technology and a continuously variable transmission.
Engine and Performance
The tractor is powered by an 8.4-liter, 6-cylinder turbocharged intercooled diesel engine. It generates a gross power of 240 hp and reaches a maximum power of 270 hp, with a torque output of 874 lb-ft at 1500 RPM. The fuel system utilizes electronic high-pressure common rail injection. To meet environmental standards, it incorporates AGCO's e3 selective catalytic reduction (SCR) system, with an optional integrated exhaust gas recirculation (IEGR) version available.
Transmission and Drivetrain
Equipped with the Techstar CVT, the tractor offers a continuously variable transmission that provides infinite forward and reverse gears. This system allows for precise speed control without shifting. Power is delivered through a four-wheel-drive system, supported by hydraulic wet disc brakes and electro-hydraulic differential locks on both the front and rear axles.
Hydraulics and PTO
The hydraulic system is a closed-center load-sensing type, delivering a total flow of 46.2 gpm at a pressure of 2,901 psi. It accommodates 4 to 6 valves for various implement controls. The rear PTO is independent, offering 1000E/1000 speeds, with an optional front PTO available for increased versatility.
Hitch and Dimensions
The rear hitch is a category III type, providing a lift capacity of 26,460 lbs at the ends and 21,336 lbs at 24 inches. The front hitch offers a lift capacity of 11,020 lbs. With a wheelbase of 122.2 inches and an overall height of 133.1 inches, the tractor is configured for heavy-duty field work.
Conclusion
The Challenger MT645C is a robust, high-capacity tractor engineered for professional farming environments requiring high torque and flexible speed management. Its combination of a powerful 8.4L engine, advanced CVT transmission, and heavy-duty hydraulic capabilities makes it a suitable choice for demanding tillage and planting tasks.
