Challenger MT655C SCR
The Challenger MT655C SCR is a powerful tractor designed for serious farm work. It has a strong Sisu Diesel engine with 6 cylinders and 234 horsepower. This engine is turbocharged and intercooled, which means it can work hard without getting too hot. The tractor uses diesel fuel and has a special system to control emissions, making it better for the environment. One of the best things about this tractor is its transmission. It has a continuously variable transmission (CVT) with infinite forward and reverse gears. This means the driver can easily change speeds without stopping to shift gears. The MT655C SCR is big and strong, weighing 25,795 pounds. It has large agricultural tires in the front and back, which help it move well in fields. The tractor also has a closed center hydraulic system, which is good for running equipment that needs a lot of power.
