The Case IH 2577 combine harvester was introduced in 2004 and remained in production until 2009, solidifying its place as a workhorse in the agricultural sector. It's powered by an 8.3L Cummins 6CTA8.3 diesel engine, producing approximately 250 horsepower. The 2577 features an Axial-Flow rotary system for threshing and separating grain. The Axial-Flow system is known for its gentle grain handling and ability to reduce grain damage, especially in crops like soybeans. The grain tank has a capacity of around 215 bushels, and the unloading auger can empty the tank at a rate of approximately 2.3 bushels per second (140 bu/min). The Case IH 2577 could be equipped with header widths ranging from 20 to 30 feet, providing versatility for various field sizes and crop types. Chopper and spreader options were available to manage residue. The cab provides operator comfort and visibility, and the 2577 proved successful in harvesting a wide variety of crops including wheat, corn, soybeans, and other small grains. Its ease of maintenance and robust design made it a sought-after model.

Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust concave clearance according to the crop being harvested. Proper concave settings minimize grain loss and damage.
- Belt and Chain Tension: Check belt and chain tension frequently. Loose belts and chains can lead to reduced efficiency and premature wear. Adjust or replace as needed.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers regularly to ensure proper airflow and prevent grain loss. Clogged sieves reduce cleaning efficiency.
- Bearing Greasing: Lubricate all bearings according to the manufacturer's recommendations. Proper greasing extends bearing life and prevents breakdowns.
