Introduction
Renault 851S Agricultural Tractor
The Renault 851S is a utility tractor produced between 1980 and 1989. Designed for general agricultural operations, this model is recognized for its mechanical simplicity and its integration of the MWM engine platform, typical of the Renault lineup during that decade.
Engine and Performance
The tractor is powered by an MWM TD226-4 turbocharged diesel engine. This 4-cylinder unit features a 4.2-liter displacement with a bore and stroke of 105 x 120 mm. It delivers a rated power of 85 hp (63.4 kW) at 2350 RPM, with a peak torque of 300.1 Nm achieved at 1500 RPM, providing consistent lugging ability for field work.
Transmission and Drivetrain
The machine is equipped with a transmission offering 12 forward and 12 reverse gears, allowing for a wide range of speeds suitable for varied tasks. While the standard configuration is a 4x2 2WD drive system, an optional 4x4 MFWD (Mechanical Front Wheel Drive) setup was available to improve traction in difficult soil conditions. Steering is facilitated by a hydrostatic power assist system, and braking is managed by dry disc brakes.
Hydraulics and PTO
The hydraulic system provides a total flow of 8.7 gpm (32.9 lpm). The rear hitch is capable of lifting up to 9,923 lbs (4,501 kg), allowing the tractor to handle a variety of heavy-duty implements. The rear PTO operates at dual speeds of 540 and 1000 RPM, ensuring compatibility with standard farm equipment.
Dimensions and Weight
Built on a 242 cm wheelbase, the tractor measures 411 cm in total length and 270 cm in height. The base operating weight is 7,144 lbs (3,240 kg) for the 2WD model, while the 4WD version weighs 8,710 lbs (3,950 kg). It is typically fitted with 7.50-18 or 13.6-24 front tires and 16.9-34 rear tires.
Conclusion
The Renault 851S represents a reliable solution for medium-scale farming operations from the 1980s. Its combination of a robust MWM engine, flexible transmission, and substantial lift capacity makes it a versatile machine for both primary tillage and general utility tasks.
