Introduction
Challenger MT845E agricultural crawler tractor
The Challenger MT845E is a high-horsepower agricultural crawler tractor manufactured by AGCO in Jackson, Minnesota, USA. Part of the MT800E series, this machine is designed for heavy-duty field operations, utilizing a track-based drive system for enhanced traction and reduced soil compaction.
Engine and Performance
The tractor is powered by an AGCO Power 12-cylinder, 48-valve turbocharged diesel engine with a displacement of 16.8 liters. It produces a gross power output of 450 hp (335.6 kW) at a rated speed of 2100 RPM, with a maximum power of 486 hp. The engine generates 1604 lb-ft (2175 Nm) of torque at 1500 RPM. Emissions are managed through a selective catalytic reduction (SCR) system, ensuring compliance with Tier IV standards.
Transmission and Drive
Equipped with a Caterpillar full power shift transmission, the MT845E offers 16 forward and 4 reverse gears. The system utilizes a hydraulic wet disc clutch controlled electronically to facilitate gear changes. The tractor features a crawler drive system paired with power differential steering, providing the necessary maneuverability and grip for heavy draft applications.
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 2900 psi, with an optional upgrade available to 85 gpm. The tractor supports 4 to 6 valves. The rear hitch is configured for Category 4 drawbar and Category 5 implements, with a rear lift capacity of 19,500 lbs (8,845 kg).
Dimensions and Operator Environment
The MT845E has a base operating weight of 42,596 lbs (19,321 kg) and is fitted with 18-inch tracks. The standard cab is designed for operator comfort during extended work intervals and includes integrated air conditioning.
Conclusion
The Challenger MT845E is engineered for large-scale farming operations requiring significant drawbar pull and consistent traction. Its combination of high-torque displacement, power-shift transmission, and heavy-duty hydraulic capabilities makes it a suitable solution for deep tillage and heavy implement work.
