Do you mean Earthway planter??
If so, I don't think you will be happy with it. I bought one to plant my market garden a few years back, and while it was better than dropping seed by hand, I was often frustrated by it's performance. I mounted it under the belly of my Farmall Cub, so I could watch it drop seed. It worked, but not well. Look at Jeng Clean seeders if you are planting more than corn. I believe Johnny's select seeds is selling them now, along with some other online retailers.
