The Earthway Seeder that we're talking about today has very simple adjustments. There's a little trap door in the bottom right next to the little rotating propeller that allows you to adjust the amount of seed, or possibly even ant growth regulator that you may even put on your yard to go from the widest opening position. And number three to number one, which is the smallest, I mean, it almost barely doesn't move. But these kinds of seeders are generally used for just that, to cover, spread seed on a bare spot in your yard. They generally don't have a high enough capacity to do fertilizer, but other materials that require low application rates, these are ideal because they're easy to store and easy to use. And they don't cover a wide swath, so you may working in a narrow place around the side of your house and this is an ideal piece of equipment.
