The 822 had a poor design in that there were no gathering chains down the side of the snouts to bring in leaning or downed stalks. Also, the stalks were cut off by the rotary knives before the gathering chains even grabbed them. If one is operated on level land and the operator is able to keep it perfectly on the row, then they can do an acceptable job. But if used on hillsides and they got off track of the row a little, stalks were knocked down and lost.
I think New Holland had the 822 in production for only a year or so. They must have heard from a lot of customers about problems because the 824 replaced the 822 in short order. The 824 was a big improvement in that gathering chains go down the sides of the snouts to pull in leaners and all stalks are grabbed before they are cut off by the rotary knives.In my area 822 heads were traded in quickly for the 824. The 822's then sat on the yards for years and were never sold.
I have had an 824 head for 5 years on an 880 harvester. It replaced the 880R2 which was worn out. In thick,heavy, tall corn , there can get to be such a pile of stalks and big ears being delivered into the throat that they back up and the feed rolls only spin on the ends of them and won't pull them on through, even with the high speed header drive gear installed. This I believe to be an inherent problem of this "low profile" style head. Never had it happen in the old style head. Only solution is to drop down a gear and slow tractor's ground speed.
I really think that the old style two row heads (717 and 880 ) did a better job at picking up downed stalks. If the old style head had the rotary stalk knives, I would rather have it than the 824. I have used the old style two row head to harvest drill seeded sorghum-sudan hybrid and it gathered practically all of it . I do not think that the 824 would do nearly as well.
