Introduction
Case IH C90 Utility Tractor
The Case IH C90 is a utility tractor produced between 1998 and 2002 as part of the C80 and C100 series. Manufactured in Doncaster, England, this machine was designed to provide a versatile platform for standard agricultural operations, offering both 2WD and optional 4WD configurations.
Engine and Performance
The tractor is powered by a Perkins 1004.40T engine, a 4.0-liter, 4-cylinder turbocharged diesel unit. It delivers a gross power output of 90 hp (67.1 kW) and a net power of 84 hp (62.6 kW) at a rated speed of 2200 RPM. The engine utilizes a mechanical direct injection fuel system with 5-hole injectors and maintains a compression ratio of 17.25:1.
Transmission and Drivetrain
The C90 features multiple transmission options to suit varying operational requirements, including a standard 8-forward/4-reverse gearbox and an optional 16-forward/8-reverse partial power shift transmission, as well as a creeper gear configuration. All models utilize a 12-inch dry disc clutch for the main transmission and hydraulic wet disc brakes for stopping power. The differential lock is mechanically operated.
Hydraulics and Hitch
Equipped with an open-center hydraulic system, the tractor provides a standard pump flow of 12.7 gpm (48.1 lpm), with an optional capacity of up to 18 gpm (68.1 lpm). The system operates at a pressure of 2500 psi (172.4 bar) and can support up to three auxiliary valves. The rear hitch is a Category II/I type with a standard lift capacity of 3,665 lbs (1662 kg), which can be upgraded with an optional package to 5,097 lbs (2311 kg).
Power Take-Off (PTO)
The tractor is equipped with an independent rear PTO. The standard configuration operates at 540 RPM, with an optional dual-shaft arrangement providing both 540 and 1000 RPM capabilities. The PTO engagement is managed via a hydraulic wet disc clutch.
Conclusion
With its robust Perkins engine, flexible transmission choices, and reliable hydraulic capacity, the Case IH C90 serves as a capable utility tractor for general farm work and medium-duty implements. Its construction and variety of configurations made it a staple of the late 1990s agricultural machinery market.
