Trusted Testimonials

"MADConcaves:
Amazing on All Crops Hard to Thrash!"

“We have been using them for years. The latest version has 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 concaves in ours in 10 mins total. You will be happy with the grain saving!”

"Great For Quick Changes Between Crops"

: “It’s very easy for us with the MadConcaves to swap them out, it takes 20 minutes and you’re off and you can do your beans or if it’s too hot to do beans we can swap concaves over and do wheat or barley.”
- K. Van Der Westhuizen SA.

Trusted Testimonials

"The inserts are quick to change and they are light, so anyone can lift them in and out."

“I liked the fact that once the main frame is in you only need to change the concave inserts when changing crop types. The inserts are quick to change and they are light, so anyone can lift them in and out."
- J. Lush, Keith SA.

Trusted Testimonials

"You think you're saving money by not replacing your concaves, but you soon get that back if you increase the performance of the header."

"You don’t have to go much quicker to make up the cost soon. They gave us a really, clean sample and good capacity"
- J. Bertola Beaumont WA.
