Introduction
Challenger MT855E Agricultural Crawler Tractor
The Challenger MT855E is a high-horsepower agricultural crawler tractor manufactured by AGCO in Jackson, Minnesota. Produced between 2014 and 2020, this machine is engineered for heavy-duty field operations, utilizing a track-based drive system to optimize traction and minimize soil compaction.
Engine and Performance
The tractor is powered by an AGCO Power 16.8-liter, 12-cylinder, 48-valve turbocharged diesel engine. It delivers a gross power output of 490 hp (365.4 kW) and a maximum power of 529 hp (394.5 kW). The engine generates 1740 lb-ft (2359.4 Nm) of torque at 1500 RPM, providing the necessary force for demanding agricultural implements. It complies with Tier IV emission standards using selective catalytic reduction (SCR) technology.
Transmission and Drive
The MT855E features a Caterpillar full power shift transmission offering 16 forward and 4 reverse gears, equipped with a hydraulic wet disc clutch. The drive system consists of a crawler chassis with 18-inch tracks, and steering is managed via a power differential system, ensuring precise maneuverability for a machine of this scale.
Hydraulics and Hitch
The hydraulic system is a closed-center, pressure-flow compensated design. It provides a standard pump flow of 58.1 gpm (219.9 lpm) at a pressure of 2900 psi (200.0 bar), with options for higher capacity configurations. The tractor is equipped with 4 to 6 valves and features a rear lift capacity of 19,500 lbs (8845 kg), supporting Cat. 4 and Cat. 5 drawbars.
Operator Environment
The tractor includes a standard cab configuration equipped with air conditioning to maintain operator comfort during extended work intervals. The electrical system utilizes a 12-volt setup with a 300-amp charging system and four 1000 CCA batteries to support its various electronic components and monitoring systems.
Conclusion
With an operating weight of 42,596 lbs (19,321 kg), the Challenger MT855E is designed for large-scale farming operations requiring significant pulling power and consistent traction in challenging soil conditions.
