Introduction
Renault 681: Standard Agricultural Tractor
The Renault 681 is a standard agricultural tractor produced between 1979 and 1980. It represents a mid-range utility machine designed for general field operations, characterized by its mechanical simplicity and robust construction.
Engine and Performance
The tractor is powered by the MWM D227-4 diesel engine, a 4-cylinder unit with a displacement of 3.8 liters. It delivers a rated power output of 68 hp (50.7 kW) at 2350 engine RPM. The engine produces a maximum torque of 169.6 lb-ft (230.0 Nm) at 1500 RPM, providing consistent lugging ability for standard agricultural implements.
Transmission and Drivetrain
The powertrain features a manual transmission offering 12 forward and 12 reverse gears. The base configuration is a 4x2 2WD system, though an optional 4x4 MFWD (Mechanical Front Wheel Drive) configuration was available to improve traction in adverse field conditions. Steering is assisted by a hydrostatic power system, and braking is managed through dry disc brakes.
Hydraulics and Hitch
The hydraulic system provides a total flow capacity of 8.0 gpm (30.3 lpm). The rear hitch is capable of lifting 8,489 lbs (3850 kg), allowing for the operation of mounted equipment. The rear PTO operates at dual speeds of 540 and 1000 RPM, ensuring compatibility with a wide range of powered implements.
Conclusion
The Renault 681 is engineered for general farming requirements, offering a balanced combination of hydraulic lift capacity and engine torque. Its design makes it a suitable choice for small to medium-sized agricultural operations requiring a durable and versatile utility tractor.
