Introduction
Challenger MT856 Agricultural Crawler Tractor
The Challenger MT856 is a high-horsepower crawler tractor manufactured by AGCO, designed for heavy-duty agricultural operations. Since its introduction in 2021, this model has served as a primary machine for large-scale farming tasks requiring significant traction and power.
Engine and Performance
The tractor is powered by a 15.3-liter (933.7 ci), 6-cylinder turbocharged diesel engine. It features liquid cooling and delivers a gross rated power of 556.5 hp (415.0 kW) at 1730 RPM. The engine produces a maximum torque of 1991 lb-ft (2699.8 Nm) at 1450 RPM, providing the necessary pulling force for intensive field applications. Maintenance intervals for oil changes are rated at 500 hours.
Transmission and Drivetrain
Equipped with the Accu-VT continuously variable transmission, the MT856 offers infinite forward and reverse speeds. This transmission type allows for precise speed control without shifting gears, optimizing efficiency during varied field conditions. The machine utilizes a crawler drive system, which enhances traction and reduces ground compaction.
Hydraulics and PTO
The hydraulic system is a closed-center, pressure-flow compensated design. It features a standard pump flow of 58.1 gpm (219.9 lpm), which can be increased to 116.2 gpm (439.8 lpm) with optional configurations. The system operates at a pressure of 2900 psi (200.0 bar) and supports 4 to 8 rear valves. The independent rear PTO offers 1000 and 1000E speed settings for implement versatility.
Dimensions and Operator Environment
The tractor has a wheelbase of 118 inches (299 cm) and an operating weight of 42,000 lbs (19,051 kg), ensuring stability during heavy draft work. The operator station consists of a standard cab equipped with air-conditioning to maintain comfort during extended operation.
Conclusion
The Challenger MT856 is engineered for large-scale agricultural operations where high power, constant traction, and hydraulic precision are required. Its combination of a high-torque engine, continuously variable transmission, and robust crawler design makes it suitable for demanding soil preparation and heavy-duty towing tasks.
