Better Thrashing Ability

Flat bar design decreases chances of hair pinning and improves threshing ability of rotor elements.

The new split frame MAD concaves with modular inserts, for Case 88’s were developed to be lighter and easier to handle and install into the combine. Once the frame is installed it is never removed, and the modular concaves (15kg) are easy to insert and quick to swap out in mere minutes with two bolts per insert. With this design, you’ll optimize your yield and saves on people power and recalibration time.

Longer wear and precision sharpness for aggressive threshing.

Primary Sales Australia has proven and tested different configurations in the field to create kits suited to Australian crops and conditions. Recommendations may vary by climate and crop conditions. The numbers .225, .300, and .375 represent the measurement of the gap between the bar; the gap being .225 of an inch for example.

Kits below show our recommended kits based on crops and conditions.
