John Deere 9750STS Combine Parts

9750STS parts and accessories

The John Deere 9750STS combine, manufactured from 2000-2003, quickly became a favorite among farmers for its efficient rotary separation system. Boasting around 330 engine horsepower and compatibility with header widths ranging up to 30 feet, this combine offered a powerful and versatile solution for harvesting. Its advanced technology and robust design contributed to increased productivity and reduced grain loss, making it a valuable asset for grain harvesting operations.

The John Deere 9750STS was introduced in 2000 as part of the STS (Single Tine Separator) series, marking a significant advancement in rotary combine technology. Production continued through 2003. It's powered by a John Deere 9.0L 6-cylinder diesel engine producing approximately 330 horsepower. The 9750STS utilizes a rotary separator with a single tine rotor, known for its high throughput and gentle grain handling. The grain tank capacity is around 300 bushels, and the unloading auger can discharge grain at a rate of approximately 2.5-3 bushels per second (150-180 bu/min). Available header widths range from 20 to 30 feet, allowing for efficient harvesting of various crops. Chopper and spreader options were available to manage residue effectively. The cab offered enhanced operator comfort and controls, including advanced monitoring systems. The 9750STS excelled in harvesting crops like corn, soybeans, and wheat, providing reliable performance and minimized grain damage.

Maintenance Tips

Concave Adjustment: Regularly inspect and adjust concave clearances based on the crop being harvested. Incorrect settings can lead to excessive grain loss or damage.
Belt and Chain Tension: Check belt and chain tension frequently, especially during peak harvest season. Loose belts or chains can cause slippage and reduced performance, leading to costly repairs.
Sieve and Chaffer Cleaning: Keep sieves and chaffers clean to ensure proper separation of grain from chaff. Regularly remove debris and adjust settings based on crop conditions.
Bearing Greasing: Grease all bearings according to the manufacturer's recommendations. Proper lubrication extends bearing life and prevents premature failure. Pay special attention to rotor and header bearings.
