Aeration and drop coverage in one package. Spiker/seeders offer all the advantages of a drop spreader (with the exception of sand/salt spreading on paved surfaces). Plus, they aerate the lawn, allowing water, sunlight and nutrients easy access to the grass roots. Especially well suited for seeding, these units save you time by allowing one-pass aerating and fertilizing. Spiker/seeder has easy on/off manual lever. Sturdy wheels provide smooth maneuverability.
