Having an issue with our new 550 bu cart. In oats especially now that the crop is up, we are seeing blank spots just after the drill has been sunk into the ground. It will be 1 or 2 manifolds each time, seed will flow for a few feet, then there will be a 6 to 8ft complete blank spot, then seed will have flowed again. After we bought the drill this winter we were warned these would have issues with oat dust building up and stopping seed flow. We clean our own seed so went as far as using our belt conveyors for all seed handling after processing to reduce amount of dust, but the issue started in our 1st field. Deere wondered how many acs we had seeded before this started, I had to tell them 1 round! Some pretty poor engineering it would appear to me. I have no idea how these drills may work with something like perenial ryegrass or something like that. Anyone else have such issues? Solution?
