Does anyone know of concave filler bars for a John Deere 9550 harvester. Apparently they are used when the concave has some wear on it. If so, are they applicable to the grate part of the concave or the rear. Part numbers would be helpful.

Install 20 series concave filler strips in the first 2 or 3 rows. For
9400, 9410, 9450, 9500, 9510, 9550 or cts use 7720 filler strips. For 9600, 9610
or 9650. Use 8820 filler strips. Filler strips can be installed through the
stone trap.

The ah130465 concave closures cover the first 5 bars of the concave.
This may hold material in the concave too long and cause excessive grain
damage or tear up straw too much and cause walker loss because of the
straw mat.

I'm not really a fan of filler bars because they decrease separation area. And those ones that install from the top with rubber keepers always come out anyway. Just install a PF prethresher plate. It'll give you more threshing and separating area and installation isn't too difficult.
