| You know I haven't studied the drag chains at length because we generally don't use them. My impression is that the idea of the drag chain is to pull the soil back in over the slot that has been thrown out by the wheel. The curvature of the tooth on the Dawn Curvetine doesn't tend to throw the soil out in the same way. The drag chain may also have some effect of breaking it up a bit more. Keep in mind that in most soils you really don't want it to be super fine over the top of the seed. If you get a hard rain it can collapse into a sort of dense area that isn't going to allow air to permeate as well. Soils or media that allow for good movement of air and water are a good thing whether younare growing orchids or corn. If you notice these Curvetines are mounted side by side and I think you would get even better action with them staggered. | |
