Sunnybrook All Crop Concaves John Deere

Sunnybrook Welding manufactures a concave system for John Deere rotary machines fitting all current and late models. Their innovative concave systems produce results that save you time, money, and most importantly, saves your back from needless strain and pain

Sunnybrook Welding manufactures a concave system for JD rotary machines, fitting all current and late models. The concave frames are designed to be half-width, making 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!
