Frequently Asked Questions

Custom threshing components—like our modular concaves, high-inertia cylinders, and impellers—are designed to match your specific crop and harvest conditions. That means better threshing, cleaner grain samples, less rotor loss, and smoother crop flow. You can save fuel, reduce downtime, and increase efficiency by using parts tailored to your needs rather than one-size-fits-all factory components. At harvest time, that difference really adds up.

Boronizing makes our components incredibly tough—up to 3x harder than standard steel. That means they last longer, resist wear better, and hold up under the toughest harvest conditions. For you, that means fewer part replacements, less downtime, and better performance all season long. It’s durability that saves you time and money.

Our concaves are fully modular, which means you can customize your setup for different crops, conditions, and combine models. Instead of swapping an entire concave, you can just change the inserts—saving time and money. The boronized, reversible bars offer exceptional wear life, and the open design improves crop flow and threshing efficiency. Whether you’re harvesting wheat, canola, soybeans, or corn, our system lets you fine-tune performance like never before.

Our components are built to perform across a wide range of crops, including wheat, canola, soybeans, corn, barley, oats, flax, lentils, peas, rye, and more. Because our concaves are modular and customizable, you can adjust your setup to match your crop and conditions—without compromising on threshing quality or capacity. Whether you’re switching between cereals, pulses, or oilseeds, our upgrades help you harvest more efficiently with less loss.

I met with the Sunnybrook team and they were easy to talk to and get information from. They are a trust local Alberta company that has been around for over 40 years and that says alot about their products and quality!

Matthew Link

Sunnybrook has a really great team and they show that they truly care about their customers. You’ll definitely feel the Alberta service, would highly recommend.

Brian Musson

I had a bent part on a hay rake. I took it to them. They built me a new one that looked as good as or better than factory.! Didn’t take them long at all very good place to deal with

George Nixon

Quality machined parts.

Our customer has two Claas 8800 combines. One is equipped with the new Sunnybrook Raptor XD APS drum. When the dew came out, the 8800 which wasn’t Sunnybrook couldn’t feed the oats, while the one with the Sunnybrook’s APS drum never slowed.

Nolan, Alberta Harvest

Running Max Thresh up front on our JD 9770 gave us the cleanest winter wheat sample I’ve ever seen. It was a night and day sample difference vs the competitor’s concave. Losses were ok with both but about a 3% dockage difference between his two machines when the took the sample in to get tested.

Devin Schutter, Schutter Mechanical

We have had very positive results with Sunnybrook products. We have installed various components in S series, Claas and most recently in John Deere X9 combine. Durability, grain quality and overall performance have been consistent in all cases.

Don Karstens

Gotta be the best concaves we’ve ever used. I’ve been driving combines for 30 years and have never seen the same success with any other concaves!

Leonard Hofer

We have sunnybrook concaves in both our combines and would not have anything else.

Brian Johnson

I have been running Sunnybrook cylinders for nearly 20 years. You can run your cylinder much slower, especially in canola. It makes a combine out of the machine. Tough conditions you do not plug and nearly no maintenance.

Paul Waldner

Sunnybrook was great to deal with being a 4 1/2 hour drive to the southeast. I had new rub bars bolted and welded to my rotor and balanced. I was back home in the same day!

Tyson Rafa

My grain buyer always asks me, how my cracks and splits are so low. I tell him, well, it is because I have Sunnybrook concaves!!

Art Northcott

The great staff at Sunnybrook Welding have helped me out with customized machined parts for a lot of my farm equipment over the years, even my old Massey-Ferguson. They have a great eye for detail.

L. Sekora

The folks at Sunnybrook are friendly, helpful, and always ready to go the extra mile for you.

W. Popowich

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.
