Case IH Concave System

LESS LOSS, MORE MONEY

Rotor loss in Corn, Soybeans, Wheat, Milo, Canola, and all other crops happens on all rotor combines because of an over-loaded separation section. The new Estes RPR Thrashing/Separating System will STOP the rotor loss in all crops.

We introduced “The Disrupter” (14 lugs bolted into the two front separation grates) in the summer of 2010 and the response was tremendous! (Disrupter lugs cut up corn shucks, green bean stems, & wheat straw). They have over 2,500 sets of Disrupters in operation, but the rotor loss problem still exists with all STS & new S series machines & also the Case-IH rotor machines when ground speed is increased. The rear concave in John Deere Rotor machines is not large enough nor opens enough to get crop through without sacrificing a lot of ground speed. Corn, Soybeans & Wheat thrash completely over the first 1 &1/ 2 round bar concaves, but very little separation will happen over the back half of the concave sections due to the small space (5/8”) between the remaining round bars.

BEST IN CLASS

The new Estes RPR Thrashing/Separating concave System has addressed all of Thrashing-Separating Issues.

The new system has a patented round bar with a notch milled in it to restrict the crop flow and force material to rub on material. Then the bars are placed progressively open to ensure more crop flow through the concave system. The flow was increased by 68%. This is all followed up by the placing of the 7 Disrupter lugs :(14 cutting edges) into your existing separating grates to finish the separation operation.

SUPERIOR IN EVERY WAY

We constantly challenge the status quo. Nothing is worse than complacency, and as a brand our culture is to dissect every single decision we make at every level of the company.

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 Estes 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 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 system and recommend it to all.

Bill Chapman , ND, JOHN DEERE 9760

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 Estes concaves in on corn and you'll pay for them in the first 300 acres.

Larry Hendon , IL, JOHN DEERE S670

Before I ran across Estes I had ran one of their competitors but hands down, these are the best concaves there is. No more rotor loss, cleaner tank and we picked up 1-1.5 MPH in the field. Take a look at them before you go anywhere else.

Garth Gentry , IN, CASE IH 9120

We first used Estes concaves in our JD 9870 models and found an dramatic increase in capacity and far less grain damage. When we started picking corn, we probably saw another an extra few bushels in the tank that we were throwing out the back. The concaves paid for themselves in just a couple days.
