Choose The Right Aftermarket Combine Concaves – Choose ESTES

It is every farmer’s need that he maximizes his harvest – a sign of his hard work paying off! Better harvest not only depends on the crop that is sown but the right equipment that is used to harvest the crop. It is imperative that an efficient aftermarket combine concaves are used as part of the harvesting equipment.



Primitively stock round bar concaves were extensively used for harvesting of crops. The disadvantages of utilizing stock round bar concaves are quite significant. Let’s assess the most important of all in the below list:

-    Difficulty in plugging of the stock round bars

-    High rotor loss

-    Unacceptable grain damage

-    Higher fuel consumption

-    Higher costs

The need to combat these damages rose high and culminated with the invention by CM Welding. The  RPR Concave system came into existence and addressed most of the disadvantages that were caused because of the stock round bar concaves.

History behind ESTES RPR Concave system

The first aftermarket combine concaves from CM Welding was in 2013. Farmers were able to see an appreciable rise in their yields due to the fact that corn crops were pulverized better and cleaner crops. Despite higher yields, the rotor loss was still an open challenge to the farmers.

The Rotor Loss Kit released by CM Welding in the year 2010 minimized the rotor losses by 33%. CM Welding then came up with RPR Concave system which has almost given the farmers zero rotor loss.

ESTES’ RPR Concave system

The RPR system then sold by Estes Performance Concaves is one of efficient aftermarket combine concaves for harvesting and is a product which is the result of close to 20 years of research, experience, and testing. The combined system is explained as shown below:

R – Restricted Flow Threshing

P – Progressively Open

R – Round Bar

The RPR system has the following distinctive features attributed to it-

•    Better grain-grain threshing because of the restricted flow threshing mechanism

•    Grains separate faster than they do on other round bar combines due to the progressively open systems

•    Round bars that are exclusively patented to the Estes make prevent plugging and give cleaner thresh

•    RPR aftermarket combine concaves suit all types of crops

•    The ESTES RPR system has addressed all thrashing and separating issues that were earlier reported as problems by the farmers

•    Slower rotor speed gives better crops and almost zero rotor loss

•    Longevity of the combines with an estimated life of 5000 hours

•    Lesser fuel consumption and high savings for the farmers
