John Deere 1085 Combine Parts
The John Deere 1085 combine, produced from the late 1970s into the early 1980s, offered farmers a reliable and efficient harvesting solution. Typically equipped with a 135 horsepower engine and available with header widths ranging from 13 to 20 feet, this conventional separator combine became popular for its simplicity and durability in harvesting various grains. Its straightforward design made it a favorite for smaller to medium-sized farming operations.
The John Deere 1085 combine was a workhorse for many farmers, manufactured from approximately 1978 to 1983. It featured a John Deere 6466D, 135 horsepower, 466 cubic inch displacement diesel engine, providing ample power for its era. The 1085 utilized a conventional threshing system with a robust cylinder and straw walkers for effective grain separation. Grain tank capacity was approximately 125 bushels, with an unloading auger capable of discharging at roughly 35 bushels per minute. Available header widths ranged from 13 to 20 feet, catering to different field sizes and crop conditions. While a chopper or spreader was optional, many units were equipped to manage residue. The cab, while not as advanced as later models, offered basic controls and visibility. The John Deere 1085 performed well in harvesting wheat, soybeans, and corn, excelling in relatively clean fields with moderate yields. Its affordability and ease of maintenance contributed significantly to its popularity.

Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance based on the crop being harvested to optimize threshing and minimize grain loss.
- Belt and Chain Tension: Inspect all belts and chains for proper tension and wear. Loose or worn belts/chains can significantly reduce efficiency and cause damage.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to ensure proper airflow and separation. Clogged screens lead to increased grain loss over the back.
- Bearing Greasing: Follow the manufacturer's lubrication schedule for all bearings to prevent premature wear and failure.
History & Background
