John Deere 1166 Combine Parts

1166 parts and accessories

The John Deere 1166 combine, produced from 1978 to 1981, was a popular conventional separator machine valued for its reliability and simplicity. Powered by a robust John Deere diesel engine delivering around 155 horsepower, the 1166 could handle a variety of crops. It was compatible with header widths up to 20 feet, making it well-suited for mid-sized farms and diverse harvesting needs.

The John Deere 1166 was introduced in 1978 as part of John Deere's '66 series combines, succeeding earlier models. This series aimed to improve operator comfort and efficiency. The 1166 is powered by a John Deere 6466D 7.6L 6-cylinder diesel engine, producing approximately 155 horsepower. It features a conventional threshing system with a 43-inch wide cylinder and a large walker area to separate grain from the straw. The grain tank capacity is around 145 bushels, and the unloading auger has an unloading rate of approximately 50 bushels per minute. Available header widths ranged from 13 to 20 feet, allowing for adaptation to various field sizes and crop types. Options included a straw chopper or spreader, and the cab offered basic operator comfort with improved visibility compared to earlier models. The 1166 excels in harvesting wheat, soybeans, and corn in relatively clean conditions. Its simpler design contributes to easier maintenance and repair.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concave clearance to ensure proper threshing and minimize grain damage. Refer to the operator's manual for recommended settings based on the crop being harvested.
Belt and Chain Tension: Check and maintain proper tension on all belts and chains. Loose belts and chains can slip, causing reduced performance and premature wear.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffer to remove debris and ensure proper grain separation. Clogged sieves can lead to grain loss over the back.
Bearing Greasing: Follow the recommended greasing schedule for all bearings. Proper lubrication prevents premature bearing failure and extends the life of your combine.
