Introduction
Case IH 7120 Row-Crop Tractor
The Case IH 7120 is a row-crop tractor produced from 1987 to 1993 at the manufacturer's facility in Racine, Wisconsin. Positioned as a high-performance machine of its era, it was designed to meet the heavy-duty demands of agricultural operations, offering 166 horsepower and versatile transmission options.
Engine and Performance
The tractor is powered by an 8.3-liter, 6-cylinder, 12-valve turbocharged diesel engine. It features a liquid-cooled system with a viscous fan and a compression ratio of 17.3:1. Designed for long-term reliability, the engine includes dual paper element air cleaners and an ether starting aid for cold conditions, with optional block and oil pan heaters available for extreme environments.
Transmission and Drivetrain
The 7120 utilizes a full-range powershift transmission, operated by a single right-hand control lever. Standard configurations provide 18 forward and 2 reverse gears, with later models adding two additional reverse gears. An optional creeper range is available, expanding the configuration to 24 forward and 3 reverse speeds. The drivetrain is offered in a 4x2 2WD setup, with an optional 4x4 MFWD (Mechanical Front Wheel Drive) available for improved traction.
Hydraulics and Hitch
Equipped with a closed-center, pressure flow compensated (PFC) hydraulic system, the tractor delivers a pump flow of 22 gpm (83.3 lpm) and a total flow of 29 gpm (109.8 lpm) at a system pressure of 2600 psi. The rear hitch is a Category III/IIIN type, controlled by an electronic lower link system, providing a lift capacity of 8,300 lbs (3,764 kg) measured at 24 inches behind the hitch point.
Operator Environment
The machine is equipped with the Silent Guardian II Cab as standard, which incorporates air-conditioning to maintain operator comfort during extended field operations. Steering is facilitated by a hydrostatic power system, and the tractor utilizes differential hydraulic wet disc brakes for controlled deceleration.
Conclusion
The Case IH 7120 serves as a robust and adaptable power unit for medium to large-scale agricultural tasks. Its combination of a high-torque engine, multiple powershift transmission variants, and capable hydraulic system makes it suitable for a wide range of row-crop applications, particularly where precise speed control and consistent pulling power are required.
