Introduction
Challenger MT555B Row-Crop Tractor
The Challenger MT555B is a row-crop tractor produced between 2004 and 2011 at the AGCO facility in Beauvais, France. It is part of the Challenger B-series, designed to handle a variety of agricultural tasks with a rated engine output of 153 hp.
Engine and Performance
The tractor is powered by a Caterpillar 3056C engine, a 6.0-liter, 6-cylinder turbocharged diesel unit. It features liquid cooling with a viscous fan and complies with Tier II emission standards. The engine operates at a rated speed of 2200 RPM and is supported by a dual-element air cleaner system.
Transmission and Drivetrain
Two transmission configurations were available: the TechStar CVT, which provides infinitely variable speeds, and the AutoPower IV, a 32-speed partial power shift transmission. Both options utilize an electro-hydraulic wet disc clutch. The tractor is available in either two-wheel or four-wheel drive, equipped with an electro-hydraulic differential lock and inboard planetary final drives.
Hydraulics and Hitch
The hydraulic system utilizes a closed-center pressure flow compensated (PFC) design, providing a total flow of 29 gpm at 2900 psi. The rear hitch is a Category II/III system capable of lifting up to 14,700 lbs at 24 inches behind the lift point. An optional front hitch is also available, offering a lift capacity of 5,500 lbs at the ends.
Operator Environment
The MT555B comes standard with a cab featuring integrated heating and air conditioning. For enhanced operator comfort, optional equipment includes pneumatic cab suspension and an automatic climate control system. Braking is managed via hydraulic wet disc brakes, with optional trailer braking support.
Conclusion
The Challenger MT555B serves as a robust and flexible row-crop tractor suitable for varied field applications. With its multiple transmission options and high-capacity hydraulic system, it is designed for operators requiring precision control and significant lifting capabilities in diverse agricultural environments.
