Introduction

Deutz-Fahr M640 Tractor

The Deutz-Fahr M640 is a high-performance agricultural tractor produced between 2007 and 2009. Part of the M600 series, this machine is designed to handle demanding field operations with a focus on power, transmission versatility, and operator comfort.

Engine and Performance

The tractor is powered by a 6-cylinder, 24-valve Deutz diesel engine with a 6.1-liter displacement. It features turbocharging and intercooling technology, delivering a rated power of 171 hp (127.5 kW) and a maximum output of 181 hp (135.0 kW). The engine produces 528.8 lb-ft (717.1 Nm) of torque at 1000 RPM, providing the necessary pulling power for heavy-duty agricultural tasks.

Transmission and Drivetrain

The M640 utilizes a ZF 7200 transmission system featuring a partial power shift with a wet disc clutch. The standard configuration offers 24 forward and 24 reverse gears with a power shuttle. An optional creeper range is available, expanding the transmission to 40 forward and 40 reverse gears. The tractor is equipped with a four-wheel-drive system, power steering, and wet disc brakes for reliable operation in various field conditions.

Hydraulics and Hitch

The hydraulic system is based on an open-center design with a standard pump flow of 21.9 gpm (82.9 lpm), with load-sensing options capable of reaching 31.7 gpm (120.0 lpm). The rear hitch is a category III/II system offering position and draft control, capable of lifting up to 13,640 lbs (6,187 kg). An optional front hitch is available, providing an additional lift capacity of 8,800 lbs (3,991 kg).

PTO and Electrical

The independent rear PTO offers 540/1000 RPM speeds, with additional economy modes (540E and 1000E) available for fuel-efficient operations at lower engine RPMs. An optional front PTO is also available. The electrical system is powered by a 12V battery with a 143 AH capacity and a 150-amp charging alternator.

Conclusion

The Deutz-Fahr M640 is a robust, versatile tractor well-suited for professional farming operations requiring high engine output and flexible gear selection. Its combination of load-sensing hydraulics and comprehensive PTO options makes it a capable platform for a wide range of mounted and trailed implements.
