Introduction

Challenger MT665 Row-Crop Tractor

The Challenger MT665 is a row-crop tractor produced by AGCO between 2002 and 2003 in Beauvais, France. As a high-horsepower model in the Challenger lineup, it shares significant design characteristics with the Massey Ferguson 8280, tailored for heavy-duty agricultural operations.

Engine and Performance

The tractor is powered by a 8.4-liter (513 ci) Sisu 6-cylinder diesel engine. This unit is turbocharged and aftercooled, featuring a liquid-cooling system and a 16.0:1 compression ratio. Rated at 250 horsepower at 2200 RPM, it is designed for sustained field performance. The engine air intake is protected by a dual paper element air cleaner system.

Transmission and Drivetrain

The machine utilizes a power shift transmission offering 18 forward and 6 reverse gears. Power is transferred via an electro-hydraulic wet disc clutch. The drivetrain is configured as a four-wheel-drive system, complemented by power steering and hydraulic wet disc brakes to ensure maneuverability and stopping power under load.

Hydraulics and Hitch

Equipped with a closed-center pressure flow compensated (PFC) hydraulic system, the MT665 delivers a total flow of 29 gpm (109.8 lpm) at a pressure of 2900 psi (200.0 bar), with an optional capacity of 39 gpm (147.6 lpm). The tractor features four hydraulic valves and a Category III rear hitch, providing a lift capacity of 19,700 lbs (8,935 kg) at 24 inches behind the lift points.

Dimensions and Operator Environment

The tractor is built on a 121-inch wheelbase with a shipping weight of 21,500 lbs (9,752 kg). It is equipped with a standard cab featuring air conditioning to facilitate operator comfort. The rear independent PTO operates at 1000 RPM, achieved at an engine speed of 2091 RPM.

Conclusion

The Challenger MT665 is a robust 250 hp tractor designed for demanding row-crop applications. Its combination of a high-capacity PFC hydraulic system, power shift transmission, and substantial lift capacity makes it suitable for large-scale farming operations requiring consistent pulling power and implement control.
