NEW! XPR concaves are not RPR concaves, they’re BETTER. Larger bar, smarter threshing, optimized spacing, greater separation, refined 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.
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. Plus, the RPR’s 90 degree bar has often been found to be too aggressive shearing off cobs and grinding grain. The XPR concave bars are larger, boasting 117% MORE effective threshing surface area than RPR pacman bars and the XPR’s threshing angle has been optimized for maximum threshing without damaging grain or breaking cobs. The difference? XPR threshes wheat, small grains and other hard to thresh crops 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. 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. Nothing beats the XPR’s Xtreme separation performance when it comes to 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, they 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. Our separation 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, our XPR cover plates are perforated 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 with grain that happens 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.
