CROP ANGEL PERFORMANCE CONCAVES

Home Of The Best-Selling RPR Concave System


 

STOP ROTOR LOSS

Every rotor combine has between 0.6% and 2% grain loss, that’s a loss of up to R300k per one thousand hectares. 
Our RPR Concave System STOPS rotor loss and works for ALL crops, no changing of concaves crop to crop. 

It pays for itself in a matter of days.

MORE CAPACITY

Increase your capacity by 30% and ground speed by 1-3 km/h. 
Our system is 68% more open so your concaves are no longer limited by high-tonage harvest, large headers and slow ground speeds. 

It’s a whole different machine with the RPR System.

CLEANER SAMPLE

Our patented Pacman bars give a cleaner thresh than stock round bars with less grain damage. 
That, accompanied with increased capacity, forces more grain-on-grain threshing for an even cleaner grain sample. 

All that means, more money in your pocket.
