Not entirely sure what the problem exactly is because I can't be there to see it. But based on your description, is sounds like the header is being run a bit high. The ears should be stripped from the stalk about 2_3 of the way up the length of the stripper plates. To accomplish this, one adjusts picking height, ground speed, and header speed to obtain that condition. Has to be an adjustment of some type. The 800 series head has worked great on the MF rotaries I've been around, especially in down or lodged corn when other heads just won't pick it up. Best of continued luck.
