The John Deere 1170 combine, produced from the mid-1980s to the early 1990s, was a popular choice for farmers seeking a reliable and efficient conventional harvesting solution. These combines typically featured engines in the 150-170 horsepower range and accommodated header widths up to 20 feet. Known for its robust design and straightforward operation, the 1170 delivered consistent performance in various grain harvesting applications.

The John Deere 1170 entered the market in the mid-1980s, filling a need for a mid-sized, dependable combine. This model utilizes a conventional threshing system, favored by many for its gentler handling of grain and straw. Powering the 1170 is typically a John Deere diesel engine, ranging from 150 to 170 horsepower with a displacement around 6.8 liters, providing ample power for most harvesting conditions. The grain tank holds approximately 140 bushels, and it unloads at a rate of about 35-45 bushels per minute. Available header widths ranged from 13 to 20 feet, allowing for adaptability to different field sizes and crop conditions. Chopper and spreader options helped manage residue effectively, aiding in soil health. The cab offered basic comfort and controls for the operator. The 1170 excels at harvesting a variety of crops, including wheat, soybeans, and barley, performing particularly well in conditions where gentle threshing is beneficial.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance to ensure proper threshing and minimize grain damage. Follow the manufacturer's recommendations for different crop types.
Belt and Chain Tension: Inspect belt and chain tension on all drive systems, particularly the feeder house and threshing components. Loose belts or chains can cause slippage and premature wear.
Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to maintain proper airflow and separation. Blocked screens reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Follow the lubrication schedule and grease all bearings regularly. Pay special attention to bearings in high-stress areas such as the header and cleaning shoe.
