Introduction
Steiger 9170: Heavy-Duty Four-Wheel Drive Tractor
The Steiger 9170 is a high-horsepower four-wheel drive tractor produced between 1986 and 1990 in Fargo, North Dakota, USA. As part of the 9100 series, this model was engineered to provide significant pulling power and operational reliability for large-scale agricultural applications.
Engine and Performance
The tractor is powered by a Cummins NTA-855 engine, a 14.0-liter, 6-cylinder liquid-cooled diesel unit. It features a turbocharger and intercooler configuration, delivering 335 gross horsepower (249.8 kW) at a rated speed of 2100 RPM. The engine produces a substantial torque of 1,131 lb-ft (1533.6 Nm) at 1400 RPM, which provides the necessary force for heavy-duty drawbar work.
Transmission and Drivetrain
Power is transferred to the ground through a full power shift transmission offering 12 forward and 2 reverse gears. The system utilizes a hydraulic wet disc clutch, ensuring smooth gear transitions under load. The drivetrain is configured for constant four-wheel drive, supported by outboard planetary final drives and hydraulic disc brakes for stopping power.
Hydraulics and Hitch
The 9170 utilizes a closed-center hydraulic system with a total flow capacity of 40 gpm (151.4 lpm) at a pressure of 2500 psi (172.4 bar). It is equipped with 3 to 4 valves to manage various implements. The rear hitch is a Type IV category system capable of a 14,000 lbs (6350 kg) lift capacity, complemented by an optional independent 1000 RPM rear PTO.
Dimensions and Operator Environment
With a wheelbase of 141.3 inches (358 cm) and an overall length of 279.5 inches (709 cm), the tractor offers high stability. The shipping weight is 29,000 lbs (13,154 kg), with a maximum weight capacity of 40,000 lbs (18,144 kg). The machine is equipped with a standard cab that includes air-conditioning to maintain operator comfort during extended field operations.
Conclusion
The Steiger 9170 is designed for professional agricultural operations requiring high torque and consistent drawbar performance. Its combination of a high-capacity hydraulic system, robust transmission, and stable 4WD platform makes it suitable for heavy tillage and large-scale farming tasks.
