Introduction
Challenger MT955B Articulated Tractor
The Challenger MT955B is a high-horsepower, articulated four-wheel-drive tractor manufactured by AGCO in Jackson, Minnesota. Produced between 2007 and 2009, this machine is designed for large-scale agricultural operations requiring significant traction and heavy implement management.
Engine and Performance
The tractor is powered by a 15.1-liter, 6-cylinder turbocharged and aftercooled diesel engine. It delivers a rated output of 460 horsepower at 2100 RPM. The engine features a 24-valve configuration and an 18:1 compression ratio, designed to meet Tier III emission standards for demanding field applications.
Transmission and Drivetrain
Power is transferred through a full power shift transmission providing 16 forward and 4 reverse gears. The system utilizes hydraulic wet disc clutches, which allow for on-the-go shifting under load. The drivetrain is built on a four-wheel-drive platform with inboard planetary final drives and articulated power steering to navigate large implements.
Hydraulics and Hitch
The hydraulic system is a closed-center pressure flow compensated (PFC) design, providing a total flow of 43.5 gpm (164.6 lpm) at a pressure of 2900 psi. It supports 4 to 6 rear valves to manage various hydraulic attachments. The rear hitch is capable of lifting up to 19,500 lbs (8,845 kg), accommodating category III and IV implements.
Dimensions and Operator Environment
The MT955B features a wheelbase of 155.5 inches and an overall width of 200 inches, providing a stable footprint for heavy-duty work. The unit has a shipping weight of 39,266 lbs with a maximum weight capacity of 54,000 lbs. The operator environment consists of a standard cab equipped with air-conditioning to maintain productivity during long operational hours.
Conclusion
The Challenger MT955B serves as a high-capacity traction solution for large-acreage farming. Its robust engine, articulated chassis, and high hydraulic output make it well-suited for heavy tillage and large-scale seeding operations.
