Case IH 9390 Tractor Parts

9390 parts and accessories

The Case IH 9390 tractor, manufactured from 1996 to 1999, was a powerful articulated 4WD machine designed for demanding agricultural tasks. Powered by a robust 400 HP Cummins N14 diesel engine, the 9390 delivered exceptional performance and reliability. Its high PTO horsepower made it a favorite among farmers needing a dependable tractor for heavy tillage and large implements.

The Case IH 9390 was introduced in 1996 as part of the 9300 series, replacing earlier Steiger-built models. It remained in production until 1999. The heart of the 9390 is a Cummins N14 diesel engine, producing approximately 400 horsepower with a displacement of 855 cubic inches (14.0 liters). This engine provided ample power for the most demanding field operations. It features a 12-speed powershift transmission, allowing for smooth and efficient gear changes under load. The PTO delivers around 335 horsepower at 1000 RPM. Hydraulic capacity is approximately 51 GPM, with typically 4 remote valves available. The three-point hitch is rated as Category IV. Common applications included primary tillage, planting large acreage row crops (corn, soybeans, wheat), and pulling large implements like chisel plows and discs. Compared to other models in the Case IH lineup, the 9390 offered a higher horsepower rating and articulated design for enhanced maneuverability in large fields, making it a top choice for large-scale farming operations.
