Introduction
Renault 921 Agricultural Tractor
The Renault 921 is a standard agricultural tractor produced between 1977 and 1980. Designed as a versatile utility machine, it served the mid-power segment of its era with configuration options suitable for various field operations.
Engine and Performance
The tractor is powered by an MWM D227-6 diesel engine. This 6-cylinder unit features a 5.7-liter displacement and produces 92 hp (68.6 kW) at a rated speed of 2350 RPM. The engine delivers a maximum torque of 248.6 lb-ft (337.1 Nm) at 1100 RPM, providing consistent lugging power for heavy-duty tasks.
Transmission and Drivetrain
The Renault 921 is equipped with a transmission offering 12 forward and 12 reverse gears, allowing for precise speed management during field work. The machine comes standard with a 4x2 2WD drive system, with an optional 4x4 MFWD configuration available for improved traction in challenging soil conditions. Steering is facilitated by a hydrostatic power system.
Hydraulics and Implements
The hydraulic system provides a total flow of 8.3 gpm (31.4 lpm). The rear three-point hitch offers a lift capacity of 8,930 lbs (4050 kg), enabling the operation of a wide range of mounted implements. The rear power take-off (PTO) supports both 540 and 1000 RPM speeds to accommodate various equipment requirements.
Dimensions and Build
The tractor is built on a 105.5-inch wheelbase with an overall length of 174.8 inches. It features dry disc brakes for deceleration. The weight varies according to the drivetrain, with the 2WD model weighing 8,489 lbs and the 4WD version weighing 9,007 lbs. Standard agricultural tire configurations include 11.00-16 front and 16.9-38 rear tires.
Conclusion
The Renault 921 remains a representative model of late 1970s agricultural engineering. Its combination of a high-torque 6-cylinder engine and a robust rear lift capacity makes it a suitable machine for general tillage, transport, and PTO-driven applications on medium-sized farms.
