Case IH 181 Combine Parts

181 parts and accessories

The Case IH 181 combine, produced in the late 1970s and early 1980s, was a popular choice for farmers seeking a reliable and efficient harvesting solution. Powered by an engine in the 100-120 HP range and accommodating header widths up to 20 feet, the 181 utilized a conventional threshing and separating system. Its straightforward design and ease of maintenance contributed to its enduring appeal in grain harvesting operations.

The Case IH 181 combine harvester was manufactured from approximately 1977 to 1984. It was engineered as a workhorse for farms of various sizes. The engine was typically a Case or International Harvester diesel engine, producing around 100-120 horsepower with a displacement around 300-400 cubic inches, depending on the exact engine configuration. The 181 employed a conventional threshing system, utilizing a cylinder and concave setup to separate grain from the plant material. Grain tank capacity was approximately 85-100 bushels, with an unloading auger capable of emptying the tank at a rate of around 40-50 bushels per minute. Available header widths ranged from 13 to 20 feet. The 181 typically came standard with a straw chopper. Cab features were basic for the time, offering some protection from the elements. The Case IH 181 excelled in harvesting a variety of crops, including wheat, soybeans, and corn. Its simple design made it relatively easy to maintain and repair, a major advantage for many farmers.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concave clearance to ensure optimal threshing and minimize grain damage. Adjust based on crop type and condition.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains. Loose belts can slip and cause reduced performance, while overtightened belts can lead to premature wear.
Sieve and Chaffer Cleaning: Clean the sieves and chaffer regularly to prevent buildup of debris, which can reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication extends the life of the bearings and prevents costly breakdowns.
