Introduction
Challenger MT635B Row-Crop Tractor
The Challenger MT635B is a row-crop tractor manufactured in Beauvais, France, between 2005 and 2008. Designed for heavy-duty agricultural operations, this model integrates a high-capacity hydraulic system and a continuously variable transmission to support diverse farming tasks.
Engine and Performance
The tractor is powered by a Sisu 74ETA, a 7.4-liter, 6-cylinder, 24-valve turbocharged diesel engine. It produces 215 hp at a rated speed of 2200 RPM. The engine cooling system features a 33.7-liter capacity, and the unit is equipped with a dual-element air cleaner for operation in dusty environments.
Transmission and Drivetrain
The MT635B utilizes the TechStar transmission, a continuously variable transmission (CVT) offering infinite forward and reverse ratios across two ranges. Power is delivered through a four-wheel drive system, supported by inboard planetary final drives and electro-hydraulic differential locks on both the front and rear axles.
Hydraulics and Hitch
The hydraulic system is of the pressure flow compensated (PFC) type, delivering a total flow of 147.6 liters per minute at a pressure of 200 bar. It supports between four and six hydraulic valves. The rear hitch is a Category III type with a lift capacity of 7,076 kg at 610 mm behind the lift point, while an optional front hitch provides an additional 3,492 kg of lift capacity.
Operator Environment and Dimensions
The tractor features a standard climate-controlled cab with heating and air conditioning, with options for pneumatic suspension and automatic climate control. The machine has a wheelbase of 307 cm and an overall length of 523 cm. The rear tread width is adjustable between 152 cm and 223 cm to accommodate various row spacings.
Conclusion
The Challenger MT635B is a versatile row-crop tractor suited for professional agricultural applications requiring precise speed control through its CVT and high hydraulic output for modern implements.
