ENGINE DETAIL
The Challenger MT475B is powered by a Caterpillar C6.6 engine, offering a robust 120 hp at 2200 RPM, making it suitable for a variety of agricultural tasks requiring significant power without compromising efficiency due to its Tier III emissions rating. Its electronic high-pressure common rail fuel system enhances fuel atomization for improved combustion and reduced emissions, though this complexity may necessitate specialized maintenance. The dry air cleaner design is advantageous in dusty environments, but users should be aware of the need for regular maintenance to prevent reduced engine performance.

CHALLENGER MT475B ENGINE
The Challenger MT475B is powered by a robust Caterpillar 6.6L 6-cylinder diesel engine, providing optimal torque and fuel efficiency for demanding agricultural tasks. With a total fuel capacity of up to 55 gallons (208.2L) when utilizing the optional tank, operators can benefit from extended run times, reducing the frequency of refueling during long operations. However, potential challenges may include weight management and maneuverability with the increased capacity, especially in tight agricultural environments.

TRANSMISSION
The Challenger MT475B features a four-speed AutoPower IV transmission, providing seamless gear shifts across 16 forward and reverse gears. This setup enhances operational efficiency, particularly in varying load conditions, while the wet disc clutch aids in smoother engagement and reduced wear. However, the complexity of a power shift system may require more meticulous maintenance and operator training to fully leverage its capabilities.

| Description | Four power shift gears in four ranges. |
MECHANICAL
The Challenger MT475B tractor features a robust 4WD configuration with inboard planetary final drives, enhancing traction and stability across varied terrains, making it suited for rugged agricultural tasks. The electro-hydraulic differential lock provides efficient power distribution, particularly beneficial in slippery conditions, while the 16-speed power shift transmission allows for smooth transitions and optimal control over a wide range of tasks. Its hydraulic wet disc brakes ensure reliability and safety during intense operations, and the standard air-conditioned cab improves operator comfort, allowing for extended working hours in demanding environments.

CHALLENGER MT475B TIRES
The Challenger MT475B tractor offers versatility with both 2WD and 4WD configurations, providing tailored traction options suitable for various agricultural tasks. The optional tire sizes enhance ground contact and stability, especially in challenging terrains—4WD with larger rear tires (540/65R38) improves flotation in wet fields. However, the selection of tire size significantly impacts fuel efficiency and maneuverability; larger tires may provide better traction but can lead to increased soil compaction.

DIMENSIONS & TIRES
The Challenger MT475B tractor, with a wheelbase of 111 inches (281 cm) and a weight range of 11,195 to 11,905 pounds, offers stability for handling various agricultural tasks. Its 2WD configuration with a front tire size of 10.00-16 and rear tire size of 460/85R34 ensures good traction, although it may limit maneuverability on uneven terrain compared to a 4WD model. Ideal for medium-sized farms requiring reliable performance on flat to gently sloped fields, the MT475B excels in tasks like tilling and planting but may face challenges in muddy or hilly conditions.
