Yes there is snow on corn, but we are running only when it is below 25 degrees f. I have been running concave at 12, and it was working good, I tried setting of 8 and 12, and 14 seemed to be the best. I don't have email so I can't receive the information from you. Sorry. like I.said it o nly seems to be one variety. It was planted late, june 4th, and seems the cob is imature.the kernals are 1_2" long and wide, so Ihave to run seive open more than usual. The corn is light in test weight, about 53lbs per bushel,but running about 140bu_acre,dry, pretty good for late corn in this area just south of london. I only have 20 acres left of this variety so will struggle thru. Merry Christmas everyone.I really enjoy this web site and read it just about every night and have learned from it.
