Archives: MAD Concaves

We recently had the opportunity to put the Bushel Plus O-Grate Concave to the test in a X9 1100 side by side comparison, and we were thoroughly impressed with its performance across both soybeans and corn.

Soybeans:
The O-Grates delivered exactly as promised! The cleaner sample and reduced loss at an increased ground speeds were noticeable immediately. Not only did it handle the beans efficiently, but the lower level of cracks in the beans was a key improvement that stood out.

Corn:
When harvesting corn, the O-Grates again exceeded expectations. We saw a cleaner sample with higher ground speeds, and the reduction in both loss and fuel consumption were significant advantage. The O-Grates performance helped us increase productivity without sacrificing quality, and we were able to cover more ground with less fuel.

Side-by-Side Comparison with X9 1100:
We performed direct side-by-side comparisons using a 50’ head for soybeans and an 18R20” chopping head for corn. In both cases, the O-Grate offered superior results in terms of sample cleanliness, efficiency, and operational costs!

We experienced cleaner a sample, less loss at higher ground speed, and less cracks with less fuel consumption.

We raise wheat, canola, flax, soybeans and sunflowers. The factory concaves on my New Holland combines were large and heavy which meant for me to change them, I had to find one or two other people to help, and the process took over an hour for each machine. With the Bushel Plus MAD Concaves, I can have both machines changed over in about 30 minutes with no extra help needed. Not only does this save time and a backache, but I can also get the combine set properly in changing conditions instead of just say it’s good enough with the old concaves. We’ve also seen a cleaner sample and picked up speed in the field over the factory concaves making these a no-brainer to run.

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 now have MAD Concaves in all our machines. 

Really clean sample. Was able to run our John Deere S780 combine to full engine load with 45-foot head in beans. 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.
