Massey Ferguson 9790 Combine Parts

9790 parts and accessories

The Massey Ferguson 9790 combine, produced from the late 1990s into the mid-2000s, offered farmers a reliable harvesting solution. Equipped with a powerful engine delivering around 300 horsepower and available with header widths up to 36 feet, the 9790 was known for its high capacity rotor threshing system that efficiently processed a wide range of crops. Its blend of power and versatility made it a popular choice for medium to large scale farming operations.

The Massey Ferguson 9790 was a pivotal combine model manufactured from approximately 1997 to 2006, representing a significant advancement in harvesting technology for Massey Ferguson. It typically featured a Cummins or Sisu diesel engine, generating around 300 horsepower with a displacement around 8.3L. The 9790 distinguished itself with its high capacity rotary separator/threshing system, using an axial rotor. This provided increased throughput and gentler grain handling compared to conventional cylinder machines. The grain tank held approximately 300 bushels, and it unloaded at a rate of around 3 bushels per second or 180 bushels per minute. Header width options ranged from 25 to 36 feet. Chopper and spreader options were available for residue management. The cab was designed for operator comfort, featuring climate control and improved visibility. The 9790 excels in harvesting a variety of crops including wheat, corn, soybeans, and barley.
