Introduction
International Harvester Hydro 70 Row-Crop Tractor
The International Harvester Hydro 70 is a row-crop tractor produced between 1973 and 1976 in Rock Island, Illinois. This machine was designed to provide reliable performance for general agricultural applications, featuring a two-wheel drive configuration and an open operator station.
Engine and Performance
The tractor is powered by an International Harvester 6-cylinder, liquid-cooled diesel engine with a 312 cubic inch (5.1 L) displacement. It produces a gross power output of 90 hp (67.1 kW) at a rated speed of 2400 RPM. The engine features a 17:1 compression ratio and utilizes a dual-stage dry air cleaner to maintain operational efficiency.
Transmission and Hydraulics
A defining characteristic of the Hydro 70 is its hydrostatic transmission, which offers infinite forward and reverse speeds within two ranges. This allows for precise speed control without the need for traditional gear shifting. The hydraulic system is of the open-center type, providing a pump flow of 12 gpm (45.4 lpm), which supports the operation of various implements connected to the type II rear hitch.
Mechanical and Dimensions
The tractor is built on a 103-inch (261 cm) wheelbase with an operating weight of 8,200 lbs (3719 kg). Maneuverability is facilitated by power steering and differential dry disc brakes. The machine is equipped with adjustable tread settings, ranging from 58 to 82 inches at the front and 60 to 98 inches at the rear, allowing for adaptation to different row-crop requirements.
Conclusion
The International Harvester Hydro 70 is a versatile row-crop tractor suited for farmers seeking a machine with hydrostatic speed control and a standard 540 RPM independent rear PTO. Its mechanical configuration and adjustable dimensions make it a stable utility tractor for mid-range field operations.
