Introduction
International Harvester 1466 Row-Crop Tractor
The International Harvester 1466 is a heavy-duty row-crop tractor produced between 1971 and 1976 in Rock Island, Illinois, USA. Designed for demanding agricultural operations, this machine offers significant power output and mechanical versatility within the International Harvester product lineup.
Engine Performance
The tractor is powered by the International Harvester DT-436, a 7.1-liter (436 ci) turbocharged diesel engine. This 6-cylinder liquid-cooled unit features a bore and stroke of 109 x 127 mm. Depending on the production year, the engine operates at a rated speed of 2400 RPM for early models or 2600 RPM for later units, providing a power output of 147 hp.
Transmission and Drivetrain
The 1466 provides two transmission configurations: a standard 8-speed gear transmission and a 16-speed transmission equipped with a Torque Amplifier. The Torque Amplifier serves as a two-speed power shift, allowing the operator to transition between direct drive and a lower speed range without using the clutch. The system utilizes a dry disc clutch, and the tractor is available in either two- or four-wheel drive configurations.
Hydraulics and PTO
The hydraulic system is of an open-center design with a total flow capacity of 21 gpm (79.5 lpm), with 12 gpm dedicated to pump flow and 9 gpm to steering. It operates at a system pressure of 2000 psi. The rear power take-off (PTO) is independent and operates at 1000 RPM at an engine speed of 2100 RPM, featuring a hydraulic wet disc clutch for engagement.
Dimensions and Capacity
With an operating weight of 13,480 lbs (6,114 kg) and a wheelbase of 105 inches (266 cm), the 1466 is built for stability during traction tasks. The rear hitch is a Category II type with a lift capacity of 5,600 lbs (2,540 kg) measured at 24 inches behind the lift point. The tractor also offers an optional factory cab equipped with heating and air conditioning.
Conclusion
The International Harvester 1466 is engineered for heavy-duty field work, combining a robust turbocharged engine with flexible transmission options and sufficient hydraulic capacity. It remains a notable example of 1970s agricultural machinery, suitable for large-scale crop production.
