John Deere 970 Combine Parts

970 parts and accessories

The John Deere 970 combine, manufactured from 1977-1982, was a popular choice for farmers seeking a reliable and efficient machine for grain harvesting. Powered by a robust diesel engine, these combines offered varying header widths to suit different field sizes. Their conventional separator system and robust design made them a workhorse in the fields, especially admired for their ability to efficiently harvest wheat and soybeans.

The John Deere 970 combine was introduced in 1977 and remained in production until 1982, filling a crucial gap in John Deere's combine lineup. It was powered by a John Deere 6466D 466 cubic inch, 152 horsepower diesel engine, providing ample power for its harvesting tasks. The 970 utilized a conventional threshing system featuring a 44-inch wide cylinder, known for its effective separation in various crop conditions. Grain tank capacity was approximately 115 bushels, and the unloading auger could empty the tank at a rate of around 35 bushels per minute. Available header widths ranged from 13 to 20 feet, allowing for adaptability to different field sizes and crop types. Chopper and spreader options were available to manage residue. While the cab was relatively basic compared to modern machines, it offered essential controls and visibility for the operator. The 970 excelled in harvesting wheat, soybeans, and other small grains, establishing a reputation for dependability in diverse agricultural environments.

Maintenance Tips

Concave Adjustment: Regularly check and adjust concave clearance based on the crop being harvested. Proper concave settings are crucial for optimal threshing and minimizing grain loss.
Belt and Chain Tension: Inspect all belts and chains for wear and proper tension. Loose or worn belts/chains can lead to inefficient operation and potential breakdowns.
Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to ensure efficient separation of grain from chaff and debris. Clogged sieves reduce harvesting performance.
Bearing Greasing: Regularly grease all bearings according to the manufacturer's recommendations. Proper lubrication extends bearing life and prevents costly repairs.
