Case IH 1420 Combine Parts

1420 parts and accessories

The Case IH 1420 combine, manufactured from 1978 to 1985, was a popular choice for farmers seeking a reliable and affordable harvesting solution. Powered by a 105 HP engine, the 1420 was available with header widths up to 15 feet, making it suitable for small to medium-sized farms. Its conventional separator system delivered efficient grain separation in a variety of crops.

Introduced in 1978, the Case IH 1420 aimed to provide a compact and efficient harvesting solution for smaller farms. Production continued until 1985. The 1420 is powered by an International Harvester DT-358 105 HP, 358 cubic inch (5.9L) diesel engine. It utilizes a conventional threshing system featuring a 30-inch wide cylinder. The grain tank holds approximately 95 bushels, and it boasts an unloading auger capable of moving grain at roughly 50 bushels per minute. Available header widths ranged from 13 to 15 feet, accommodating various row spacing. Options included a straw chopper or spreader for residue management. The cab offered basic operator comfort and controls, a significant improvement over open-station models of the era. While versatile, the 1420 excelled at harvesting small grains like wheat and soybeans due to its efficient conventional separator design.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance to ensure optimal threshing and minimize grain loss. Refer to the operator's manual for specific settings for different crops.
Belt and Chain Tension: Inspect all belts and chains for wear and proper tension. Loose belts and chains can cause slippage and damage components.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffers to remove debris and ensure efficient grain cleaning. Clogged sieves can lead to increased grain loss.
Bearing Greasing: Grease all bearings according to the recommended schedule in the operator's manual. Proper lubrication is crucial for extending bearing life and preventing premature failure.
