We apologize for any inconveniences or if you
have not heard back from us yet on your inquiry.
Demand has been tremendous and we are working
overtime right now to service current orders.
Every rotor combine loses 3-5 bushels per acre. Our RPR Concave System stops rotor loss which means more $$$ in your pocket.
Increase capacity by 30% with no plugging, less broken cobs and a better grain sample. This results in MORE YIELD without increasing losses and better productivity.
Increase ground speed up to 5+MPH. Plus, our RPR system works in ALL CROPS which means no more changing out concaves – simply add or remove cover plates.
Slow your rotor speed, with more grain-on-grain threshing. Our concaves have a patented Pacman notch which gives you significantly better threshing over stock round bar concaves.
How much money are you losing? Every second you operate with factory concaves you are throwing money out the back. Rotor loss in corn, soybeans, wheat, milo, canola, and all other crops happens on all rotor combines because of an over-loaded separation section, but there is good news.
The new Estes RPR Concave System STOPS rotor loss in all crops meaning more money in your pocket rather than lost in the field. Best of all, the RPR system pays for itself and fast.
We installed a set of your concave sets in one of our S680's and we are really pleased with results we're seeing! We run JD large wire in the other 2 machines also 680's and although they work ok we really like the performance of your product... We have harvested wheat, oats, canola and peas so far using your concaves and they work great so much that we would like to order 2 more sets!Lloyd Friesen , Canada, John Deere S680
Within the first day of running Estes RPR Concaves we could see the difference, cut rotor loss to zero, cut crack and skin checks in nearly nothing. Very impressed and happy with the RPR System and recommend it to all.Bill Chapman , ND, JOHN DEERE 9660
Our rotor loss completely stopped in corn and soybeans! Our sample improved greatly from slower rotor speed, less broken cobs, and less fines. You put a set of RPR concavaes in on corn and you'll pay for them in the first 500 acres.Larry Hendon , IL, JOHN DEERE 9770
Before I ran across these guys, I had originally bought one of their competitors system's but hands down, their concave system is superior. It not only is more efficient, it is better built too. Take a look at them before you go anywhere else!Garth Gentry , IN, CASE IH 7088
We first used RPR concaves in our JD 9600 models and found an dramatic increase in capacity. Our grain is also better quality which translates into better yield, the paid for itself within months!Larry Brown , MO, JD 9660 STS
I saw their expo at the Farm Progress Show after speaking with some other farmers decided to give their system a shot and I am so glad I did! I have completely eliminated rotor loss and couldn't be happier.Rick Furches , MO, JD 9660
