Introduction
Challenger MT845 Agricultural Crawler Tractor
The Challenger MT845 is a heavy-duty agricultural crawler tractor produced by AGCO between 2002 and 2004. Designed for high-draft applications, this machine utilizes a track-based drive system to maximize traction and minimize soil compaction in demanding field conditions.
Engine and Performance
The tractor is powered by a Caterpillar C12 turbocharged diesel engine. This 11.9-liter, 6-cylinder liquid-cooled inline unit produces a gross power output of 380 horsepower at a rated speed of 2100 RPM. The engine features a compression ratio of 16.0:1 and is supported by a dual-element paper air cleaner system.
Transmission and Drive
The drivetrain consists of a full power shift transmission providing 16 forward and 4 reverse gears, allowing for precise speed management under load. The machine is equipped with hydraulic wet disc brakes and power steering, ensuring effective control of the 18,144 kg chassis. Power is transferred to the ground via 18-inch tracks mounted on a 299 cm wheelbase.
Hydraulics and Hitch
The hydraulic system utilizes a closed-center load-sensing design, capable of a primary pump flow of 164.6 lpm (43.5 gpm), with an optional capacity of up to 223.3 lpm. It supports between 4 and 6 rear valves operating at a system pressure of 200.0 bar. The rear hitch is a Category IVN type, offering a lift capacity of 8,845 kg, complemented by an independent rear PTO operating at 1000 RPM.
Operator Environment
The MT845 features a standard factory cab integrated with air conditioning to maintain operator comfort during extended field operations. Electrical systems are powered by a 12-volt setup, utilizing three batteries and a 160-amp charging system.
Conclusion
The Challenger MT845 is engineered for large-scale agricultural operations requiring high levels of sustained traction and hydraulic output. Its combination of a high-torque Caterpillar engine and a robust crawler undercarriage makes it suited for heavy tillage and primary cultivation tasks.
