We demo’d a set of O-Grates in an X9 this fall in both soybeans and corn. We found it noticeably easier to get a high-quality sample than with competitive concaves and picked up ground speed while achieving near zero yield loss. Amazing! We have already ordered O-Grates for all our machines next fall.

Really clean sample. Was able to run combine to full engine load with 45 foot head. Not common.

We love them! They are a lot lighter and easier to deal with than the stock concaves, they’re amazing.

Love em, absolutely love em, people ask about them and I’d do it again in a heart beat.

They are excellent, super quick to change between crops, they do a better job than factory ones. I brag about them to everybody.

We all like them, I bought a set, my neighbors, we really like them a lot! We like the small grain concaves, the fingers. Easy for us old guys to change in and out. My fingers were clogging up, Murray told me to switch them around, and that worked great.
