I am looking into a brillion primary seeder to plant about 3 to 4 acres of grass. I am justifying the purchase by reasoning the seed will be wasted money if it doesn't take, and it's too much work to cover with straw. I was also planning to use it to overseed the existing lawn and the new growth in the future. Will I be able to overseed with it, or I'll need to purchase an overseeder?
