Was that not done before the beater grate curtian was invented to stop material from getting to the front of the walkers. One combine mod. outfit recommended it. First 9x00 JD's lost a lot of grain over walkers without it.
i have a breater grate curtain in the combine but i am still not happy with the job it does in wheat barley and oats in canola it does great so i guess its been tried then i assumeIJ thanks
