Need help with ours. The seed firmers are rounded on the bottom and don't "firm" too much. This is how it was when we got it. Should they be more flat to help push the seed down? Didn't get a whole bunch of help from Hiniker when I called. Seems like they need a different profile to help catch the bean and place it in the bottom. Right now some get in the bottom and then others are floating around a little. It definitely make for abnormal germination rates. We bought it on a straight toolbar, then moved the units to an old IH folding row cultivator bar. Never seen another one here in NW IN. Especially behind a Kubota. Everyone talks about us that's for sure. Thanks for your help.
