John Deere 9470-STS Combine Parts

9470 STS parts and accessories

The John Deere 9470 STS combine, produced from 2010-2013, offered farmers a reliable and efficient harvesting solution. Powered by a robust John Deere PowerTech engine producing approximately 325 horsepower, it efficiently harvested a variety of crops. Known for its single tine separator (STS) rotary design and compatibility with a range of header widths, the 9470 STS quickly became a popular choice for increased throughput and grain quality.

The John Deere 9470 STS was part of the Single Tine Separation (STS) combine series and was manufactured from 2010 to 2013. This combine is equipped with a John Deere PowerTech 9.0L 6-cylinder diesel engine, delivering around 325 horsepower (242 kW). The 9470 STS utilizes a rotary separator system, featuring a 30-inch diameter rotor for effective threshing and separation of grain. It boasts a grain tank capacity of approximately 300 bushels (10,600 liters), maximizing time in the field. The unloading auger provides a discharge rate of around 3.0 bushels per second (180 bu/min), minimizing unloading time. The 9470 STS is compatible with a wide array of headers, accommodating widths from 20 to 30 feet for grain platforms and up to 12-row corn heads. Options included straw chopper and spreader attachments for managing residue. The operator cab is designed for comfort and efficiency, with advanced monitoring and control systems. The 9470 STS excels in harvesting corn, soybeans, wheat, and other small grains.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust the concaves to ensure proper threshing and minimize grain loss. Consult 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, especially those driving the separator and header. Loose belts and chains can reduce efficiency and lead to premature wear.
Sieve and Chaffer Cleaning: Regularly clean the sieves and chaffers to prevent buildup of debris. Clogged sieves can reduce cleaning efficiency and increase grain loss.
Bearing Greasing: Lubricate all grease fittings on a regular basis, paying close attention to bearings on the header, separator, and unloading auger. Proper lubrication extends bearing life and prevents costly repairs.

History & Background

Introduced in 2010, the John Deere 9470 STS was designed to provide increased harvesting capacity and efficiency compared to previous models. The STS rotary system became a standard for John Deere combines because of its gentler threshing action, which reduced grain damage and improved sample quality. The 9470 STS served as an important step in the evolution of combine technology, offering enhanced productivity and reliability.
