improve Combine Performance for your John Deere

reversible concaves make JD Combines Better

John Deere - The Original 'Green Technology'!

Sunnybrook manufactures a concave system for JD rotary machines, fitting all current and late models. The concave frames are designed to be half-width which makes them much easier to lift and change.

These precision manufactured frames (6 vs 3 OEM concaves) accommodate a bolt-on lip for the front position. Seven box inserts are installed in each frame, which adds an array of crucial features.

Reversibility adds extra life to the concave for more bang for your buck,
Replaceability at a fraction of the cost delivers huge savings,
Improved threshing and separating, for a higher quality, cleaner sample,
Additional stone protection with shear bolt mounts is sheer genius!

Concave boxes in a JD rotary system share commonality with Case IH late model Axial Flow machines.

component Upgrades For Conventional JD Combines Fit To a 't'

John Deere still offers conventional Harvester technology with the T670 (T series) machines. These legendary machines share much commonality with the venerable 9600 through 9650 series wide-body conventionals and have many parts still available through your John Deere Dealer. Sunnybrook manufactures an impressive array of upgrades and components for these incredibly durable and productive machines. These include:

Rub bars
Heavy duty concaves
Stainless steel wear edge concaves
Enclosed Gen 2 Cylinders
Tine Paddle back beaters

Sunnybrook concaves are tough as nails
Sunnybrook concaves are tough as nails and quick to change out when they do catch a rock or two. I wouldn’t waste combining time using a factory concave unless I really had to.
