Introduction
Challenger MT975B Agricultural Tractor
The Challenger MT975B is a high-horsepower, four-wheel-drive articulated tractor manufactured by AGCO in Jackson, Minnesota. Produced between 2007 and 2009, this machine is designed for heavy-duty agricultural operations requiring significant traction and power.
Engine and Performance
The tractor is powered by a 6-cylinder, 24-valve, 18.1-liter (1106 ci) turbocharged and aftercooled diesel engine. It delivers a rated power of 570 hp (425 kW) at 2100 RPM. The engine features a 16.3:1 compression ratio and is equipped with a dual dry element air cleaner to handle demanding field conditions.
Transmission and Drivetrain
The MT975B utilizes a full power shift transmission providing 16 forward and 4 reverse gears, allowing for on-the-go shifting under load. The drivetrain features articulated power steering and inboard planetary final drives. Braking is managed by hydraulic wet disc brakes, and the machine includes optional electro-hydraulic differential locks for the front and rear axles to enhance traction.
Hydraulics and PTO
The hydraulic system is a closed-center PFC (Pressure Flow Compensated) type, operating at a pressure of 2900 psi (200 bar). It provides a total flow of 43.5 gpm (164.6 lpm), with an optional capacity of 59 gpm (223.3 lpm), supporting 4 to 6 rear valves. The independent rear PTO operates at 1000 RPM at an engine speed of 2000 RPM.
Dimensions and Capacity
With a wheelbase of 155.5 inches (394 cm) and a total length of 298 inches (756 cm), the tractor is built for stability. It has a shipping weight of 39,767 lbs (18,038 kg) and a maximum weight capacity of 60,000 lbs (27,216 kg). The rear hitch is configured for Category IVN/III or IV, with a rear lift capacity of 19,500 lbs (8,845 kg).
Conclusion
The Challenger MT975B is engineered for large-scale farming applications where high drawbar pull and hydraulic capacity are essential. Its robust construction and power output make it suitable for intensive tillage and heavy implement operation.
