Challenger MT655D - Horsepower, Weight, Specs, Problems, Price & More

Engine

The engine is a 6-cylinder liquid-cooled AGCO Power turbocharged air-to-air intercooled diesel. It has a displacement of 513.8ci / 8.4L with a bore/stroke of 4.370x5.709inches / 111x 145 mm. The engine meets Interim Tier IV emission standards and uses selective catalytic reduction (SCR) for emission control. It has a gross power output of 265hp / 197.6kW and a maximum power output of 295hp / 220.0kW. The fuel system is electronic high-pressure common rail with thermostart pre-heating. The compression ratio is 16.7:1 and the engine is started with a 12-volt electric starter.

Transmission

The transmission is a continuously variable transmission (CVT) that provides an infinite number of speed ratios. It allows for smooth and efficient power transfer to the wheels. The CVT also provides automatic speed matching to the load, which helps to reduce fuel consumption and increase productivity. The transmission is controlled electronically and has a maximum speed of 31 mph (50 km/h). It also has a creep speed function for precise control in tight spaces.

Brakes

The brakes are hydraulic wet disc brakes that provide reliable and consistent stopping power. They are located on all four wheels and are controlled by a pedal in the cab. The brakes are also equipped with an electro-hydraulic differential lock for improved traction in slippery conditions. The trailer brake can be either pneumatic or hydraulic, depending on the user's preference. The cab is standard with air-conditioning and OptiRide Plus hydraulic suspension AGCO System 150 (optional); AGCOMMAND (optional).

Steering

The steering is hydrostatic power steering that provides precise and responsive control. It is controlled by a steering wheel in the cab and allows for easy maneuverability in tight spaces. The AGCO Power 8.4L 6-cylinder diesel engine also provides additional power for steering when needed.

Common Problems

Users have reported issues with the four-wheel drive system, which can sometimes fail to engage or disengage properly. The hydraulic wet disc brakes have also been known to wear out quickly and require frequent maintenance. Some users have also reported issues with the cab suspension system, which can be noisy and uncomfortable. The electro-hydraulic differential lock can also be slow to engage, which can be frustrating for users. Finally, some users have reported issues with the CVT transmission, which can sometimes be slow to respond to changes in load or speed.

What Users Like

Users appreciate the standard tires on the Challenger MT655D, which are front: 480/70R34 and rear: 520/85R46. They provide excellent traction and stability in a variety of conditions. Users also like the smooth and efficient power transfer provided by the CVT transmission. The hydrostatic power steering is also a popular feature, as it provides precise and responsive control. Finally, users appreciate the cab standard with air-conditioning and OptiRide Plus hydraulic suspension AGCO System 150 (optional); AGCOMMAND (optional), which provides a comfortable and ergonomic workspace for long hours in the field.
