Introduction
Challenger MT455 Utility Tractor
The Challenger MT455 is a utility tractor produced between 2002 and 2004, manufactured in England by AGCO. It is engineered for general agricultural applications, sharing a technical lineage with several Massey Ferguson models of the same era.
Engine Specifications
The tractor is powered by a Perkins 3054 DITA turbocharged diesel engine. This 4-cylinder, liquid-cooled unit features a 4.0-liter displacement and a compression ratio of 17.3:1. It operates at a rated speed of 2200 RPM and utilizes a thermostart pre-heating system for cold-weather reliability.
Transmission and Drivetrain
The MT455 offers significant operational flexibility with three distinct transmission options: a 24-speed power shuttle, a 12-speed syncromesh, or a 12-speed mechanical shuttle. All configurations utilize a wet disc clutch to manage power delivery. The machine is available in both two-wheel and four-wheel drive variants, supported by power steering and hydraulic wet disc brakes.
Hydraulics and Hitch
The hydraulic system is an open-center design delivering a total flow of 25 gpm (94.6 lpm) at a pressure of 3046 psi (210 bar). It supports 2 to 4 SCV valves for implement control. The rear hitch is a Category II type, equipped with electronic draft control, providing a lift capacity of 4100 lbs (1859 kg) measured at 24 inches behind the lift point.
Operator Environment and Dimensions
The tractor features a two-post folding ROPS as standard, with an optional air-conditioned cab available for improved operator comfort. The machine has a wheelbase of 93 inches (236 cm) and an overall width of 81 inches (205 cm). It is typically configured with 14.9R34 front tires and 18.4R34 rear tires.
Conclusion
The Challenger MT455 is a versatile utility tractor designed for standard farming tasks. Its range of transmission choices and robust hydraulic capacity make it suitable for operators requiring a reliable, mid-range machine for mixed agricultural operations.
