Case IH 4166 Tractor Parts
4166 parts and accessories
The Case IH 4166 tractor, produced from 1995 to 1997, was a popular choice for farmers needing a versatile machine. Powered by a Cummins 5.9L diesel engine delivering approximately 125 engine horsepower and around 105 PTO horsepower, the 4166 excelled in various field tasks. Its robust design and reliable performance made it a workhorse on many farms.
The Case IH 4166 was introduced in 1995 as part of the 4000 series tractors, filling a crucial gap in the Case IH lineup for medium-sized farms. Production continued until 1997. Under the hood, the 4166 features a Cummins 5.9L 6-cylinder diesel engine, producing approximately 125 engine horsepower and a displacement of 359 cubic inches (5.9 liters). This engine provided ample power for a range of tasks. The tractor came standard with a mechanical transmission, typically offering 18 forward and 6 reverse gears, providing a wide range of speeds for different field conditions. The PTO delivered approximately 105 horsepower at 540 RPM. The hydraulic system boasted a capacity of around 22 GPM (gallons per minute), powering multiple remote valves for implements. It features a Category II 3-point hitch with a lift capacity of approximately 6,300 lbs, suitable for handling various implements. The 4166 was often used for row crop work, hay production, livestock operations, and light tillage applications. Unlike some of the larger models in the Case IH lineup, the 4166 offered a balance of power, size, and economy, making it a practical choice for farmers with smaller to medium-sized operations.
