The Case IH 1670 combine was introduced in 1987 as part of the updated 1600 series, replacing earlier models and building upon their reputation for dependable grain harvesting. Production continued through 1992. The 1670 is powered by an International Harvester DT-402 6.6L (402 cu in) diesel engine rated at approximately 215 horsepower. This engine provides ample power for threshing and separating various grain crops. The combine features a conventional threshing system with a 30.5-inch wide cylinder, allowing for efficient grain separation. The grain tank holds approximately 215 bushels, and unloading is achieved with a high-capacity unloading auger, moving grain at a rate of 75 bushels per minute. Available header widths ranged from 15 to 30 feet to accommodate different field conditions and crop types. Options included straw choppers and spreaders for residue management.

Maintenance Tips
- Concave Adjustment: Regularly inspect and adjust the concave clearance to ensure optimal threshing performance and minimize grain loss. Refer to the operator's manual for specific settings based on the crop being harvested.
- Belt and Chain Tension: Maintain proper tension on all belts and chains to prevent slippage, wear, and potential breakdowns. Regularly inspect for wear and replace as needed.
- Sieve and Chaffer Cleaning: Clean the sieves and chaffer frequently to remove debris and ensure efficient grain separation. Clogged sieves can lead to increased grain loss and reduced harvesting efficiency.
- Bearing Greasing: Grease all bearings regularly according to the manufacturer's recommendations. Proper lubrication is essential for preventing premature wear and extending the lifespan of bearings.
