Introduction
Challenger MT455B Utility Tractor
The Challenger MT455B is a versatile utility tractor produced between 2004 and 2013 at the AGCO manufacturing facility in Beauvais, France. It belongs to the MT400B series and shares significant mechanical architecture with the Massey Ferguson 5455.
Engine and Performance
The tractor is powered by a 4.4-liter, 4-cylinder Caterpillar 3054T turbocharged diesel engine, which produces 95 horsepower at a rated speed of 2200 RPM. This engine, also marketed as the Perkins 1104C in certain regions, utilizes a liquid-cooled system and is compliant with Tier 2 emission standards.
Transmission and Drivetrain
It features the Autopower IV transmission, providing 16 forward and 16 reverse speeds. The system includes a four-speed power shift across four ranges, operated via an electro-hydraulic wet disc clutch. The tractor is available in both two-wheel and four-wheel drive configurations, supported by inboard planetary final drives and an electro-hydraulic differential lock.
Hydraulics and Hitch
The hydraulic system offers high versatility with either an open-center pump providing 26.4 gpm or a closed-center load-sensing (CCLS) system delivering 29 gpm at a pressure of 2900 psi. The Category II rear hitch is equipped with electronic top-link draft control and telescopic stabilizers, allowing for a lift capacity of 7285 lbs at 24 inches behind the lift points.
PTO and Operator Environment
The independent rear PTO offers multiple speed settings including 540, 540E, 1000, and 1000E RPM, managed by an electro-hydraulic clutch. The operator station comes standard with a Roll-Over Protective Structure (ROPS), with an optional factory cab featuring air-conditioning for improved working conditions.
Conclusion
The Challenger MT455B is a robust utility tractor designed for a wide range of agricultural tasks. Its combination of a reliable engine, flexible transmission, and high-capacity hydraulics makes it a suitable machine for general field operations and heavy-duty implement management.
