    Combines

    When talking combines I see sieve capacity is most often mentioned as a limitation but for me with my Case combines it is mostly rotor loss in canola. Anyone see the same or is it just something I do?

      What are you calling exceptiable loss?
      We are usually at half b/a in canola with the 9870..
      This yr with dry conditions it was up to 3/4 bu/a..
      Pods were tuff..rotor at 700 knocked it out..concave at 30...

          If I throw a sq foot pan under the combine right in the middle with the spinners on and I get about a gram of seed. I know I should take the spinners off an catch everything in a tray to get accurate number. I have done a kill stop and can always find seed mixed up with straw at the back of the rotor cage and nothing at the back of the chaffer and the loss monitor shows the same.

              Jd clinic told us rotor at 750.
              Better separation..to slow just augers it out.

                We have are rotor running at 600 so should try faster but you here of over thrashing all the time. I also notice that when the humidity goes up so does the rotor loss.

                  The big 2 seem to think only HP matter to farmers.

                  Yes I think a few cracks is better than rotor loss. Remember when looking in a pan or at the ground that cracks might not be coming off the rotor but off the chopper.

                    get that rotor spinning if there is loss in tough conditions.

                    rotor(s) fast as possible without cracking
