Every since I have had this combine, I can't get as clean a sample in the grain tank as I could with the old MF 750. I cut a sample of rye last Saturday afternoon(TOO wet!!). The straw on the ground looked good, only found 1 rye seed in the head, couldn't see any on the ground, but there was some seeds laying on the rear axle. Looked in the grain tank, several whole stems and heads, lots of heads in there also. I had the concave set on 2 and the cylinder about 950 or so. Too wet to try to adjust and cut some more.
I took the inspection door off at the front of the straw walkers to look inside for any large holes, everything looked good. BUT, how wide should the openings in the concave be? They looked awful wide compared to what I remember from the 750. I couldn't reach far enough to measure, so I stuck bolts into the opening to get an idea how wide they are. A 5/8's bolts is loose and a 3/4 is too big, so I'm guessing the openings in the concave are about 11/16" wide. The previous owner only ran corn, could this concave be a special one for corn?? How wide should the openings in the concave be? If it ever dries enough to go, I'm gonna close the concave till it rubs and the open it a little and speed up the cylinder. Just curious about the size the openings in the concave should be. Chris
