Whenever you are having harvesting operations to perform in the farming task, then you can rely upon combine concave. However, it is crucial to select the most appropriate agricultural equipment to protect the harvested crops from getting damaged. Not only the agriculture machinery but also aftermarket combine concaves will be assisting out in protecting the quality of crops and increasing the yield. So, it is important to attain the right information about the aftermarket combine parts to secure the best products. The combine concave components are extremely crucial for the farmers who are searching for enhanced productivity in farming operations. Always use the parts that go well with the specific farming equipment. So, using the right combine equipment will be ensuring that farmers can harvest efficiently in less time.

Let’s find out some important considerations about aftermarket combine concaves:

Aftermarket Combine Parts Functions

The important functions which are performed by this particular agriculture machinery include:

• Conduct smooth threshing operation during harvesting season

• The machine also performs the task of separating of harvested crops from chaff and seeds

Working Process Of Combine Concave Parts

The increased speed of the rotor will be separating the crop and chaff. It will also be removing the crops from all the seeds. A high spinning rotor comprises several distinctive meshed components. Such parts are adjustable and facilitate the small-sized grains, as well as the, chaffs to pass through. So, it is important to gain information about the aftermarket combine concaves to secure the right component. The grains as well as the seeds that will be separated during this particular procedure get collected within the grain bag. This will be preventing the scattering of the grains as well as the chaff.

Ways To Minimize Grain Damage

When the clearance is not maintained properly, then there is a tendency for the grain particles to get damaged. So it is extremely crucial to maintain the clearance between both the cylinder as well as the concave. In case of not selecting the appropriate size aftermarket combine concave, then the grain particles may get damaged. There will also be an uneven flow of the material during the process of harvesting. Under the conditions when the space between components is too wide, the unwanted chaff will also be passing through the mesh. In case, this situation occurs, then there will be a mixing of the grain with the chaff of the combine concave components. Also, it would not be possible to carry out the separation of the grains manually. The high-performance agriculture equipment parts are made up of premium grade material. So, so they actually result in high combined speed, minimum rotor loss and complete satisfaction of the customers. So in case the farmer is frustrated with the performance of the combine c
oncave, whether it is about the high rotor loss, damaged cracked grains, low capacity or dirty samples, it is simply the best time to change the aftermarket combine concave parts.


It is important to collect the appropriate information before purchasing right aftermarket combine concaves. Many manufacturers are willing to extend you the right information concerning the clearance settings. You can also look for the best-recommended aftermarket combine concaves online by the leading manufacturers.

The use of combine harvester has revolutionized agriculture and has made life easy for the farmer. Prior to the arrival of this equipment, farmers would carry out harvesting manually. This was a cumbersome process and needed a lot of time and manpower. The labor needs would increase with the increase in the size of the farm. The combine harvester changed this all. Farmers could now finish harvesting much earlier using a fraction of the manpower they used before. They were also able to save time, improve the yield, and thus make more money.

What is the combine harvester?

The combine harvester is a piece of farming equipment that has automated the process of harvesting. The use of combine harvester in harvesting has helped in automating three activities related to harvesting. Reaping, winnowing, and threshing are three harvesting related activities that were done manually. The combine harvester now makes it easy for a farmer to carry out these activities faster and more efficiently.

How is it used?

The use of combine harvester involves using this machine in the field at the time of harvesting. The machine needs to be driven by an operator who is trained on using the machine. The machine settings need to be adjusted keeping in mind the crop harvested. One of the benefits of using a harvester is that the same equipment can be used to harvest different crops.

Once the settings are adjusted, then the machine is driven through the field. As the machine moves through the crop, the cutter bar in the machine cuts the crops and pushes it inside. The crops are then moved through a conveyor belt to the processing area. A threshing drum would beat the crops to separate grains from the stalk. The grain then falls into a tank in the machine.

The chaff and stalk collected move towards the back of the machine from where they are thrown out. Another piece of equipment can be used to collect the straw and prepare bales for further usage. As the machine plows through the farm, the grain is harvested and collected in the grain tank. In large fields, the grain tank can be filled up very fast. In such a situation, there is an un-loader that can move the grain to a trailer attached to the harvester. The header of the machine is where the cutting of the crop happens. Changing the header can help harvest different crops.

Why use this equipment?

combine harvester history

The harvester makes harvesting easy and saves time and effort. The equipment is helpful in increasing the yield of crops. Most importantly, it can help in improving the quality of the yield.

There is no doubt that the use of combine harvester has helped a farmer to become more profitable. The efficiency and effectiveness of harvesting have increased thanks to the use of the harvester. As a result, the farmer is able to produce a higher quantity of crops at better quality. This has helped the farmer increase his revenue. The investment in a combine harvester produces good returns for farmers.

Improving the performance of the harvester and crop combines has picked up pace over the past few years. The all crop harvester gets drawn by a tractor used in the late 1960s. They used this crop combine to harvest legume crops for seed, all grasses, and some flowers. The sickle bar cutting head had different lengths, 60 inches in some and 66 inches in others. Most of these are in excellent condition and are famous for their low maintenance and high dependability. You can get an all crop combine for sale for a reasonable price.

Inspect the Model Before Buying

These machines are small, so you will need more machines to harvest a large area. Or, if your farm is small, you can make do with one. Check the model number when you inspect all crop combine for sale. Each has a specific design, so they work for set conditions. The All Crop 40 works with Model B and C tractors of Allis Chalmers company. They made only 15,000 units, and each could harvest one acre per hour. They made them from 1938 to 1940.

Action and Trouble for All Crops

Concaves help with gentle threshing of soybean and corn or hard threshing small grain. Learn how to tackle the problems with your all crop combine for sale so you can fix them. The first thing that happens is plugging. The aggravation is more during the wet season when you see crop material hair pinning around the concave bars. Plugging reduces the combine capacity so you have to deal with it early. Grain damage and loss are inevitable. Using an angled bar design will help the crop flow smoothly. This will reduce plugging.

Choosing a Concave Kit

When you get an all crop combine for sale, you expect results. These investments range between $39,000 and $45,000 for KX7 concave kits. Compared to this, you pay $5,000 to $7,000 for the aftermarket all-crop concaves. You can use the latter for all crop applications. Even when you have to buy two or three KX7s for your harvest, the cost evens out when you factor in the value of maximizing performance for each crop. Each concave ranges between $470 and $775 and comes with high-wear additives that extend the life of the product two to three times.

Problems with Harvest

The other big problem is when you get cracked grain and see whitecaps with your harvest. This common occurrence occurs when you don’t match the crop needs and threshing capacity well. When you use the KX7 all crop combine for sale, you will get rid of this problem. They deliver better grain quality for all the crops because they have helically angled interpreter bars that deliver early.

Useful Aspects that Improve Quality of Harvest

Aggressive threshing helps, and so does the softened edge of the helical bar. The cladding wearing protection reduces the damage to the grains. There is also a significant promotion of air disruption. This leads to better grain-on-grain threshing. Since there is no contact with the metal parts of the thresher, the grain damage becomes less. You can configure the KX7 to swap threshing and separating boxes so you don’t have to change between crops.

Working smart is now possible because of smarter machines and tools available to farmers. It is time to leave the old rustic methods behind and use the latest from one of the finest in the field, XPR 2 Concaves. Though many acknowledge the efficacy of this new concave, one must get a deeper insight into what goes into the technology to truly appreciate it. So, here we are analyzing the wonderful science behind this marvelous offering.

Same Concave for All Crops

If anything, the XPR 2 Concaves has gotten better because of the introduction of new features. Farmers prefer using the concave because of its customary feature that allows them to use the same concave for all crops. This saves the farmer time and effort because they don’t have to remove the concave and use a new one at the end of each harvest. Also, the new concave has 30% more power giving a boost to the harvest drive. More power will help the farmer to get the work done faster.

Better Design Cuts Losses


The cover plates have perforations making it better suited for the harvesting work. Superior threshing occurs due to the better features making the process very efficient. The wear bars remain extended in the new XPR 2 Concaves giving them a longer life. But the feature that touches the heart of the farmers is the way it stops rotor loss. Usually, the loss due to grain dropping to the ground while harvesting amounts to 2-6 bushels for each harvested acre. Another thing the farmer can do is to make maintenance repairs to the harvester before they start harvesting. If there are loose belts or stones trapped in the concave, it can cause imperfect threshing. Cover plates produce a cushioning effect for the grains providing better protection.

Improved Speed of Harvesting

This kind of loss amounted to $15,270 for 500 acres. By stopping this rotor loss, the farmer becomes eligible for a profit of over $30,000 for every 1000 acres. The speed of harvesting has improved now to over 5000 bushels in an hour. Better orientation of the gaps and a good clearance in the new XPR 2 Concaves helps the movement of the grains through the grains. Enough gaps helps the grains move out of the concave without getting crushed. This prevents the splits, cracks, and fines that would occur otherwise.

Higher Capacity Improves Harvesting Efficiency

The capacity of the XPR 2 Concaves has increased. Due to this, it is possible to harvest more grain at one time. Improved capacity helps in decreasing the harvest time making it a more efficient process. The ground speed of the XPR 2 Concaves has improved by 2-3 mph. You will need to spend less time on the field and this is a good thing. The Xtreme Separation Grate is heavier and beefier and capable of better threshing without causing damage to grains. There is no more grinding and plugging get eliminated.

The use of the best technology will help the farmer make more profit. Installing superior concaves helps them achieve more without having to do anything more.

The new season brings huge responsibilities for the farmer and the biggest one is to make the harvest profitable. The combine concaves are so named because they perform three vital functions, threshing, reaping, and separating. But, one can experience many kinds of losses such as rotor loss. One can bring down rotor loss in harvesters only by switching to a superior concave system. Does one look for any other things in a concave system?

Important Things to Check in a Concave System

A wise farmer examines the good points of any concave system. The things to look for in the top combine concaves are as follows:

1. The concave must suit all crops.

2. Ground speed should be 2-3 times more than that of conventional harvesters.

3. The harvester must have 65-70% more capacity.

4. It should have good grain flow.

5. It works well with the top models such as Case IH and John Deere.

One Concave for All Crops

This helps save time and effort between crops. And by using the same concave all the time, the farmer gets a better feel of his machine helping him make the right fine-adjustments for each crop.

Improved Ground Speed

The contact time needed with the crop gets reduced because the concaves need less clearance. The threshing drum beats the cut crop with efficiency to remove the grain from the stalks. You don’t have to unplug the machine and can keep on harvesting.

Capacity Should get Enhanced

The angle of the concaves has a design to improve the threshing area with better contact. In typical combine concaves, grain loss is as high as 10-20%. By improving the threshing area, it is possible to improve capacity by 60% or more.

Concave System with a Good Crop Flow

Improved crop flow eliminates plugging. The unwanted chaff gets removed along conveyors designed to help improve grain movement. Effective threshing reduces fines, splits, and cracks by improving material-on-material contact.

Compatible with Top Harvester Models

Make sure you use those concave systems that are compatible with top harvesters like Case IH and John Deere. The grain flow is better in these models and increases harvest speeds by 5-10% at least.

Types of Grain Loss

The grain loss occurs at every stage of the harvesting process. They remain grouped as:

● Pre-harvest losses

● Set-up losses

● Machine losses

Pre-harvest losses happen due to natural reasons such as shedding. We can make this lossless by choosing a crop type with good genetics. The set-up losses will include every loss you suffer up to the harvesting stage.

The machine losses happen due to the design of the harvester. Here is where one can prevent losses by using well-designed combine concaves systems. If you sow 100 kg/hectare, the average grain loss is as follows:

1. Wheat – 27.2

2. Chickpeas – 6.2

3. Barley – 22.9

4. Red lentils – 32.8

5. Oats – 29

Less cracked or damaged grains improves the yield. You can do this by using superior concave systems that enhance the grain flow.

Use the best concave systems to outdo what you did last year. This is possible through the use of the latest technology and state-of-the-art analytic software. If you do, you get better grain quality along with lower grain losses.

Agriculture requires the use of various equipment to fasten up work. The process of harvesting is a tedious one that takes a lot of time. Combine or combine harvester is innovative equipment that can be used for harvesting. It is named so as it can be used to combine three different harvesting operations – reaping, threshing, and winnowing. Combine concaves play a key role in the working of a combine. It is a part of the combine harvester used for specific functions.

What is a combine concave?

Combine concaves refer to the trough, which is an essential component in the combine harvester. To understand what a combine concave is, the working of this equipment needs to be understood. The combine has a front part known as the reel that pulls the grain stalk and pushes it inside the machine. The grain stalks are then moved up on a conveyer belt to the threshing cylinder. This is one of the main components of the machine.

JD harvester

The cylinder rotates over the concave at high speed. As this process continues, the grain kernels and the stalk heads get separated. The hay is then separated and the kernels fall through the slits that are provided in the concave. Below the concave is a grain pan. It vibrates and has sieves that ensure chaff and other material are removed and the grain kernels are moved into the grain tank.

As can be seen, combine concaves are essential in the process of threshing and separating. At the time of threshing, the concave helps in removing the seeds and separating them from the stalks. In the separation process, the seeds are separated from the chaff and other material and sent to the grain tank. The effectiveness of the entire process depends on the wiring pattern of the concave and also its clearance distance.

Managing the concave

Combine concaves need to be managed to ensure the entire process goes on perfectly well. There is space between the rotating cylinder and the concave. This ensures a smooth flow of material. It is important to set the space correctly. Providing too much of space will not allow the grains to separate from the stalk. If space is too less, then the stalk can get damaged. The manufacturer/dealer can help in making this setting. You may need to change this setting depending on the type of crop you harvest.

One Set Is All It Takes For All The Crops Out There

The concave types depend on the crop. You can opt for a concave with narrow wires if you are harvesting barley and wheat. The grains here are small and the slits need to be narrow. Wide-wired concaves are also available. They are perfectly suited for harvesting corn and beans, as the seeds are larger and need more space to fall through.

The combine concave is an important component of the combine harvester. Different types are available in the market that can be used depending on the usage of the combine. You can get the type you want based on the crops that you grow in your field.
