I bought an old 300 series platform and put 9" pans on in 12" spacing. You have to modify the feeder a bit on the header to hook up to the newer rotaries and the reel has to come off, but it is not needed anyway. By having a header just for the pans, it saves me the hassle of putting them on and taking them off. Not a huge job but it does take some time. I have harvested solid seeded flowers and 30" rows. Both work real well. Weeds don't bother much as they tend to go under the pans. You can drive about as fast as you want. We only had a problem with dust igniting from static on a combine one year. It was EXTEMElY dry with very low humidity. We're talking less than 15% humidity. We were dragging a chain but it didn't help. The ground was bone dry, also. From about 10:00 in the morning until early evening it was a real problem. That was the time of day when the humidity was at its lowest. If I had it to do again, I would run only at night as there was no problem then. This only happened one year so I think the conditions have to be just right to be a problem. As for using a cornhead, you have to buy some adapter plates to cut the stalks off to go on the cornhead. Not cheap and again, somewhat time consuming. Buying a row crop head is an option that works OK but you won't harvest as fast with them as you will with pans. I've never used these pans for confection flowers. I hope they'll work as I'm trying some confections this year. I think the key there is to get a decent stand so the flowers are not real thin so the stalk won't be quite a large. I can't hardly think that the stalks are going to be larger than 3" in diameter 3 or 4 feet above ground.
