There are a couple options.
Sunnybrook welding
Percision farm parts
Sorry don`t have the links but you can google them.
I run the Sunnybrook style and they work well for us.

Look at Howard Concaves too. They are full size concaves but don't need to be changed. We harvest canola, durum, lentils and soybeans and never change concaves.

Do you have what you would consider hard threshing wheat? Never used these but always been sceptical on what they would do in tough wheat. Would be awesome to never change. Also are you running them in all 3 or just the first one?

We are running all 3. The openings in the front concave are different than the back 2. We used to grow Strongfield durum which was a harder threshing durum but don't know how it would compare to say Glenn wheat, which i've heard is very hard threshing. The full set of concaves is under $3K and they come with filler plates for the 2 front concaves.

Is there any difference between running the Howard's concaves vs. the factory ones with filler plates?

I called Precision farm parts, and left my number
to get a return call with some questions that I have
about their concaves.


No reply in over 2 weeks, so they are either not in business
or don't care much. :43:


I will check out the Sunnybrook, they look like they
will separate the wheat.

I am now considering the Sunnybrook half size concaves,
I like the looks and the lighter weight. I use a round
bar for soybeans and corn.


2014 was my first year with a 9770 and I could not get
the small wire concaves to thresh out the white caps.
That is after installing 3 covers. Really frustrating
with 70 bus. wheat, and having 3% dockage.


I could always grind it out with my 9610.


For those that use the Sunnybrook, how do you set
them up? The first 4, and then a regular small wire?
Looking for advice before I order.

I use them in place of the first two factory concaves(4 sections sunnybrook) then a wide space JD in the 3rd position.
The guys at Sunnybrook can give you the proper configuration of concaves for your machine. some used a smooth half section then 3 max thresh and some all 4 sections max thresh.
Hope they work well for you. I run Kuchar elements with them. The concaves helped the white caps quite a bit, not eliminated but a big difference, and no more filler plates.:54:

Back again, I'm thinking about going with 4 of the MaxThresh,
Sunnybrook, KX-7 here in the US, in the front, and a JD round
bar in the rear.
That way for soybeans I can just pull, the fronts, and put all round
bars in. I talked to Gerald Foster, at Sunnybrook today.


What do others think of that setup?

Howards seem to work best for us fair increase in capacity from oem concacves. We run three with no filler plates they are not required with variety of wheat we grow. Dockage is under a percent ,we use them in wheat,peas,canola. S-series combine. Very pleased with them
