Case IH 4186 Tractor Parts

4186 parts and accessories

The Case IH 4186 tractor, manufactured from 1976 to 1979, was a powerful workhorse for its time. It featured a 300 HP V8 diesel engine, delivering substantial power for heavy tillage and large-scale farming operations. Its robust design and high PTO horsepower made it a favorite among farmers seeking a dependable tractor for demanding tasks.

The Case IH 4186 was introduced in 1976 as part of International Harvester's (later Case IH) expansion into high-horsepower articulated tractors. Production continued through 1979. Powering this machine was a Cummins V-8 diesel engine, delivering approximately 300 horsepower and a displacement of 903 cubic inches. This engine provided ample torque for pulling heavy implements. The tractor utilized a robust 10-speed transmission, offering a wide range of speeds for various field conditions. The PTO delivered around 225 horsepower, available in 1000 RPM configuration for running large implements like forage harvesters and grain carts. Hydraulic capacity was significant for the time, supporting multiple remote valves for controlling implements. The 3-point hitch was a Category III, capable of lifting heavy loads. Farmers commonly used the 4186 for primary tillage operations like plowing and disking, as well as for large-scale planting and harvesting. Its size and power distinguished it from smaller tractors in the Case IH lineup, catering to the needs of larger farming operations.
