Sunnybrook concaves are tough as nails

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.

The great staff at Sunnybrook Welding have helped me out

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.

Low Cracks and Splits in Grain

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!!

The Customer Service is Impeccable

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!

Sunnybrook makes a combine out of the Machine

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.

Would not want anything else

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

The Best Concaves Ever Used

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!

Positive Results with Sunnybrook

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.
