CUSTOM CONCAVES
DESIGNED TO BE AGGRESSIVE!
Innovative bar and grate style modular and one piece concaves are built to last from AR200 metal, allowing for longer wear and sharpness. Customize your combine to the crop with different grate spacings sized for everything from alfalfa to chickpeas.
The new split frame concave with modular inserts, for John Deere and New Holland, was developed to be lighter (68lbs) and easier to handle and install into the combine. Once the frame is installed it is never removed, and the modular concaves (30lbs) are easy to insert and quick to swap out in mere minutes with two bolts per insert. This design optimizes your yield and saves on man power and recalibration time.
The CASE IH one piece concaves are built for peak performance. Select your combine below to find its configuration guide and price list.
The numbers .225, .300, .375, .437 represent the measurement of the gap between the bars. The gap being .225 of an inch.
