XPR vs RPR Concaves


NEW! XPR concaves are not RPR concaves, they’re BETTER. And sold ONLY here. Larger bar, smarter threshing, optimized spacing, greater separation, perforated cover plates  = SUPERIOR Performance. Sure your grandpa can use them, he will never have to change them out. And you will put more money in his pocket with that extra couple thousands of bushels you put in the grain tank. In short, you will probably be the new favorite grandchild.


XPR Concaves are for ALL crops. They STOP rotor loss in all crops. They thresh all crops WITHOUT tailings and unthreshed heads. ELIMINATE cracks, splits and broken kernels. Run your rotor slower. Increase your ground speed. Go from corn to beans to wheat all with ONE set of concaves. Just pop-on cover plates and go.


The new XPR Concave System has addressed all of threshing-separating issues farmers face today. As well as all the problems with the RPR system and 90 degree bar.


The RPR Concave System does great in restricting the flow of crop, BUT it has often underperformed in small and hard-to-thresh grains like wheat resulting in unthreshed heads in the tank. Plus, RPR’s have a 90 degree bar which has often been found to be too aggressive breaking cobs and grinding grain; the problem worsens in high-moisture corn where soft cobs are easily sheared by the 90 degree bar’s knife-like edge. XPR threshing bars are not 90 degrees (actually, less than even 50 degrees). The XPR concave bars are larger, boasting 117% MORE effective threshing surface area than RPR’s bars and the XPR’s threshing angle has been optimized for maximum threshing without damaging grain or breaking cobs. The difference? XPR threshes wheat and other hard-threshing small grains COMPLETELY and without tailings, whitecaps and cracked grain often experienced with the RPR system. In addition, our XPR concaves are engineered to retard and slow the flow of crop for maximum grain-on-grain threshing meaning you can run your rotor slower and more open resulting in SUPERIOR grain quality without grinding grain. Nothing beats XPR’s performance in high-mositure corn, no more grinding grain. The XPR’s spacing is also more open than stock so vastly more threshed grain is unloaded in the concave section, preventing an overloaded separator BUT not too open like the RPR resulting in unthreshed heads or cobs in the tank. In short, the XPR concave system threshes FASTER and captures SOONER.


What’s better than the RPR’s 14 disrupter fingers? 143 of them, to be exact. The XPR separation grate boasts 143 fingers of interrupting, fluffing and tossing the crop mat to capture any loose grain before being spit of the back of the combine lost. PLUS it bolts right up. The XPR’s Xtreme separation grate’s performance is unbeatable capturing loose grain caught up in chaff and MOG.  SUPERIOR separation and NO downtime means MORE money and valuable harvest time.


Additionally, the RPR Concave System’s disruptors perform great as an internal straw chopper. BUT in wheat, the RPR’s disrupters chop the wheat straw up too finely overloading the return with tailings and make it difficult setting the fan without blowing out wheat seed. Plus, they are a PAIN to install and worse than changing concaves when having to remove them for small grains. XPR’s separation grate fingers do NOT pulverize wheat straw or get knocked out like the RPR disrupters. This means no need to add or remove those pesty and irritating “disruptors” when transitioning from wheat to any other crop.


Lastly, XPR concaves have PERFORATED cover plates so that grain is evenly distributed onto the augers as it’s threshed. There is no more problem of overloading one side of the auger or grain unable to escape making it more prone to cracks and splits that can happen with the RPR concave’s adjustable cover plates. Our cover plates prolong grain-on-grain threshing while keeping excess trash out so you have a clean grain tank.
