From The Field

In Their Words

“
Case IH

The Razors Edge Concaves have completely changed how we run our combine. The grain flows smoothly, letting us take in more crop and run faster without any machine loss, and the grain is evenly distributed instead of overloading one side.

John Deere

Our wheat sample was on par with a competitor product running three cover plates, with no cover plates. On nine different soybean varieties our samples have been great, again running no cover plates.
