John Deere 9550SH Combine Parts
The John Deere 9550SH combine, manufactured from approximately 1999-2002, provided farmers with a robust harvesting solution. Powered by a John Deere engine producing around 250 horsepower, it offered header widths up to 30 feet. This combine utilized a specialty header rotary separator, which contributed to its popularity for its improved grain quality and reduced losses compared to conventional combines of the time.
The John Deere 9550SH was introduced in the late 1990s as part of John Deere's SH (SideHill) combine series, designed to excel in challenging terrain. It was produced from approximately 1999 to 2002. The 9550SH is powered by a John Deere 6.8L 6-cylinder diesel engine, producing around 250 horsepower. The separator is a specialty header rotary design (single rotor), which differs significantly from the standard conventional cylinder/concave threshing system. It features a 220-bushel grain tank and an unloading auger with a rate of approximately 2.1 bushels per second (126 bu/min). Available header widths ranged from 20 to 30 feet, accommodating various field sizes. Chopper and spreader options were available to manage residue. The cab offered improved operator comfort and controls for increased productivity. The 9550SH proved capable in harvesting a variety of crops, including wheat, soybeans, and corn, especially where hillside operation was a need.

Maintenance Tips
- Concave Adjustment: Regularly check and adjust concave clearance based on crop type and condition to optimize threshing performance and minimize grain damage.
- Belt and Chain Tension: Inspect and maintain proper tension on all belts and chains to ensure smooth operation and prevent slippage or breakage.
- Sieve and Chaffer Cleaning: Clean sieves and chaffers frequently to remove debris and ensure proper airflow, which is crucial for efficient grain cleaning.
- Bearing Greasing: Regularly grease all bearings according to the manufacturer's recommendations to prevent premature wear and failure. Pay special attention to bearings in high-stress areas like the header and separator.
