In 1999 we started to develop a High Output Concave,(contre-batteurs) to deal with the increasing yields , which were requiring Combine Harvesters to thresh and seperate higher volumes of grain and straw . We launched our High Output Concave,(contre-batteurs) in 2000 and it proved to be an instant success . Advantages include
- Faster ground speed
- Reduced losses over the straw walkers
- Cleaner Sample
- Less straw breakage
