A concave has two functions-threshing and separating. It does not require fancy machined bars or multi designed boxes. Also, it should not need cover plates. If you need cover plates you probably need a different concave. Adding cover plates just makes your rotor shorter and is asking for rotor loss.
Many of the new "designer" concaves are too open and too closed at the same time. They should also not cost in excess of $4000 for a set.
Our simple flat bars give more threshing surfaces and openings than any other concave on the market. They are simply better at an affordable price.

*Bars made of Hardox 400 steel-up to 3 times factory life
*Concaves use bolt on feed lip-can rotate position
*300 acre return policy
*Available for JD& Case IH Rotary combines
*Cover plates not required-will thresh green stem beans
The cleaning fan in the S Series combines is the same as the 70 Series used. While adequate for the 70 Series' smaller shoe area, it is not efficient enough for the bigger chaffer and sieve.The Fan Relocation Brackets are direct replacements for the factory brackets. They move the fan down and rearward to make the fan fit the housing as it should. The cut-off point is reduced from 1" to 1/4". This makes the fan much more efficient and eliminates the dead spots present in the factory set up. If you want to see the dead spots, look at your chaffer and sieve after they have been used for a season. The wear patterns are apparent.
Installation is simply a matter of removing the fan bearings and brackets and replacing them with the new brackets.The same belt is used and fan speed is not affected.
The fan relocation brackets are a must to supply enough air for the sieve extension
The redesign that JD did to the cleaning shoe on the S Series created some big issues. Please read the analysis of the S Series cleaning issues found under the More tab. This shoe extension greatly improves these issues. It reduces the load on the return system by about 1/2. By reducing this load, the rethresher will actually work as it is intended. Grain damage from good clean grain going through the return system is greatly reduced. The rear section of the chaffer can be adjusted to perform as it should, instead of being shut down to prevent the return from overloading.
The average install time is 3-4 hours, and requires some fab skills, a cuttoff wheel, or a plasma cutter. Detailed instructions are included along with all the hardware needed. This may seem like a pain, but remember, we didn't design this mess, we are only trying to correct it. Available in spacings for small seed, or large seed.
Replaces flimsy factory feeder house seal. This seal is made of 10 ga. steel. The factory seal is 14ga. This seal is rigid, holds it's shape and seals all across the width of the feeder house. We have come up with a simple, but effective end seal to prevent the leaks the factory seal is famous for in small seeds. The factory seal will wear through in less than 1000 hrs. This seal should have at least double the life, besides paying for itself in seed loss prevented.
Available in solid, or slotted versions. Slotted version helps eliminate dirt in crops such as beans, peas, etc.
Replaces factory feed plate. Factory feed plate is designed so that the hinge is part of the wear surface, so it will wear the hinge out in less than 1000 hrs. The HSI feed plate is designed so that the hinge is not only heavier, but is not a wear point. Life should exceed factory by 2-3 times.
Available in solid, or slotted versions. Slotted version removes dirt in crops such as beans, peas, etc.
The lower seal on the clean grain gearbox used on John Deere combines from the 9600 thru the S Series is exposed to the grain and any dirt and foreign material. Dirt and even whole grain can be forced thru the seal into the gearbox. When enough material is forced in to soak up and harden the oil in the gearbox, bearing failure results. Usually when this
occurs, not only the bearings fail, the lower shaft is damaged beyond use. This gearbox costs in the neighborhood of
$2000. The parts alone to rebuild the gearbox are in excess of $500,.
This simple $55 seal (including new oil seal) will stop the dirt and foreign material from entering the gearbox, ensuring long life.
Installation is as simple as folding the bin loading auger down, removing the nut and drive dog, sliding the seal over the shaft and replacing the dog and nut. Should take no more than 10 minutes.
This seems like good, cheap and simple insurance.
BTW-don't forget to check the oil in this gearbox annually.
