WHY BUSHEL PLUS MAD CONCAVES?

Designed to be aggressive with quality, reliability, and durability top of mind!

Swapping out traditional round wire combine concaves for our innovative bar-and-grate style modular MAD Concaves™ results in more efficient threshing, getting your grain out of the head and into the hopper quicker for decreased rotor loss and less dockage. This means higher quality crops and more money in your pocket.

In addition to increased quality and reduced loss, our fast and easy-to-change modular designs allow you to quickly swap out inserts in minutes. Therefore, you’ll save you valuable time, which is critical in a busy harvest season.

CUSTOM MAD CONCAVES

The numbers .225, .300, .375, .437 represent the measurement of the gap between the bar; the gap being .225 of an inch.

SPLIT FRAMES AND ONE-PIECES

The new split frame MAD Concaves with modular inserts, for John Deere and New Holland, were developed to be lighter (68 lbs) and easier to handle and install into the combine.  Once the frame is installed it is never removed, and the modular concaves (30lbs) are easy to insert and quick to swap out in mere minutes with two bolts per insert.  With this design, you’ll optimize your yield and save on people power and recalibration time.

WHAT FARMERS ARE SAYING ABOUT MAD CONCAVES!

 Amazing on All Crops Hard to Thrash!

“We have been using them for years. The latest version have no wires, flat plates with slots. They are amazing in all crops hard to thrash. We combine red clover, alfalfa and flax with no blanks, the wheat is so clean this year it looks like it has been cleaned. It is interesting to note that they have built a half set and hangers that are easy to change for a JD as well! I can change the four concave in ours in 10 mins total. You will be happy with the grain saving!”

Staff – Great to Deal with and Provided Ample Information and Advice

“We are very happy with our MAD Concaves. Keeping the frames in the combine makes changing concaves between crops a one person job. You can mix and match what grates you’d like to use depending on the conditions, making them very versatile.

We were able to open up the clearance and increase capacity, while either improving or keeping the sample consistent. We saw fewer whitecaps in wheat along with less cracking. Capacity in canola also increased, and we were also able to greatly reduce un-thrashed bols in flax, even under less than ideal conditions.

We were worried we might miss filler plates. But, there was no looking back. Staff was great to deal with and provided ample information and advice. We’re very happy with our investment, thank you!”

Stronger. Easier to Work With. 

“Think diesel tuner or 6” lift for your diesel truck. They are beefier. Stronger. Easier to work with. In addition, the company has a real knack for customer service. They may be slightly rough around the edges but they know their stuff. And they appreciate their customers. We bought a set of concaves for one of our CR combines and it does a better job of threshing and cleaning the grain than the stock concaves. When we bought it though, they provided very specific combine settings that were quite different than the settings we had been using for years. And it worked. Low throw over. Cleaner sample.”

Changeable Inserts is a Fantastic Idea.

“Bought 6 of these this year. Was able to pick up .5-.7 mph in canola due to reduced losses, and the changeable inserts is a fantastic idea.”
