The John Deere X Series is the top of the combine lineup, built for operations that need to harvest the most bushels in the fewest days. A dual separator, a large Dyna-Flo XL cleaning shoe and a JD14 engine paired with the ProDrive XL transmission are designed to keep capacity high and fuel use per bushel low.
Koenig Equipment sells and supports X Series combines across Ohio and Indiana. Request a quote on either model and our team will help you set up the combine, headers and technology for your operation.

Both models share the integrated G5Plus CommandCenter display and StarFire receiver with available SF-RTK. The X9 1100 adds engine power, grain tank capacity and unload speed.

A combine this size is a big part of your harvest plan, so service has to be just as dependable. Our ag technicians handle seasonal maintenance and repairs, an agriculture off-season inspection checks belts, chains, augers and threshing components between seasons, and mobile maintenance brings help to the field.
Genuine John Deere parts are stocked at your Koenig store and on Koenig Marketplace. Schedule service or talk with your store about the work your combine needs.
