SE MN | This idea has been around for a while and nobody could figure it out. There was a company that made a cyclone shaped deal that replaced part of the row unit, but it never caught on, not sure what the problem was. I've been told in the past that optimal seed placement makes a real difference on the scale of 10%. If the arrow tube actually works everything else will be completely obsolete in three years. Be prepared to see 2 year old speed tubes advertised for free. | |
