Introduction
Lamborghini R 904: Technical Specifications and Overview
The Lamborghini R 904 is a classic agricultural tractor produced between 1972 and 1979. Developed by Lamborghini, this machine belongs to the heavy-duty segment of its era, offering a balance of mechanical simplicity and performance for diverse farming operations.
Engine and Power
The R 904 is powered by a 5.0-liter, 4-cylinder air-cooled diesel engine. It delivers a rated power output of 92 hp (68.6 kW) at 2090 RPM. The use of an air-cooled system reflects the specific engineering approach of the manufacturer during this period, focusing on thermal efficiency without the need for a liquid cooling circuit.
Transmission and Drivetrain
The tractor features a synchronized transmission available in two configurations: a standard 12-speed forward and 3-reverse gearbox, or a 16-speed version equipped with a creeper range for low-speed precision tasks. It is available in both two-wheel drive and four-wheel drive variants, supported by wet disc brakes and power steering to enhance operational control.
Hydraulics and PTO
The hydraulic system utilizes an open-center design with a pump flow of 8.5 gpm (32.2 lpm). The rear hitch is a Category II type, providing a lift capacity of 8,818 lbs (3,999 kg). The independent rear PTO supports both 540 and 1000 RPM speeds, allowing for broad compatibility with mounted and trailed implements.
Dimensions and Build
The tractor is built on a 94.5-inch wheelbase. The 4WD model weighs approximately 7,959 lbs, while the 2WD version weighs 7,452 lbs. It is equipped with a four-post ROPS structure for operator protection. The ground clearance varies by configuration, reaching up to 15.8 inches for the 4WD model.
Conclusion
The Lamborghini R 904 is a versatile and robust tractor, well-suited for medium-to-large scale agricultural tasks. Its combination of a high-torque air-cooled engine, multi-speed transmission options, and significant lift capacity makes it a reliable workhorse for field work and heavy implement management.
