What Makes Our Upgrade Better

MODULAR, ALL-CROP FLEXIBILITY
Harvest cereals, peas, canola, or corn without constant concave changes. Sunnybrook’s modular concaves seamlessly transition between crops and conditions, eliminating downtime and improving efficiency compared to OEM systems.

PROVEN THRESHING PERFORMANCE
Independent PAMI testing in canola showed Sunnybrook’s Max Thresh concaves delivered up to 47% higher rotor capacity than OEM small wire concaves when extrapolated to low loss conditions. That means cleaner threshing with less grain left behind.

ELIMINATE ROTOR LOSS & IMPROVE GRAIN QUALITY
Our concave design significantly reduces rotor loss and delivers cleaner grain samples with lower dockage levels. Farmers see better bushel weights and reduced grain damage in the tank.

HARVEST FASTER, WITH CONFIDENCE
Productivity trials demonstrated an 8% increase in total machine productivity compared to OEM in dry canola. More acres per hour, without sacrificing sample quality.

BUILT TO OUTLAST OEM
Heavy-duty construction and precision balancing mean Sunnybrook concaves endure thousands of field hours, with consistent performance season after season. Fewer replacements = stronger ROI.

TAILORED TO YOUR NEEDS
Choose our versatile all-crop solution or optimize with Easy Thresh and Hard Thresh options for specialized conditions. No cover plates needed, saving setup time while boosting combine performance.

LARGE GRAINS

Designed for crops with large seeds and looser hulls that separate easily. These crops require minimal force and allow for higher throughput with less wear on the machine. Easy Thresh concaves prioritize smooth material flow and reduced grain damage.
Typical Crops: Corn, Soybeans, Canola, Lentils, Peas, Sunflower, Dry Beans

STANDARD GRAINS

Built for crops that need a balanced combination of aggressiveness and gentleness. These concaves provide consistent separation without over-processing, handling crops that are moderately tough to thresh while maintaining grain quality.

Typical Crops: Barley, Oats, Rye, Mustard, Hemp, Safflower

SMALL GRAINS

Engineered for crops with tight husks, small seeds, or fibrous plant material that demand maximum threshing action. Hard Thresh concaves offer aggressive separation to handle resistant crops while ensuring durability and performance under challenging conditions.

Typical Crops: Wheat (Spring, Durum, Winter), Flaxseed, Alfalfa, Clover

SEPARATOR GRATES

Heavy-duty Construction.
Designed for effective Threshing and Separation.

Why SunnyBrook?

Mark R., Alberta Grain Grower

We upgraded our S780 with Sunnybrook concaves last harvest and saw the cleanest sample we’ve ever pulled off the field. Paid for itself in grain savings.
