What is an Overseeder?

The Classen TS-20 turf overseeder is a multipurpose machine for seeding a new lawn or overseeding an existing lawn. The front seed drop ensures follow-up soil coverage for better seed germination. The blades are designed with a cutting edge on both ends, which doubles blade life.Click to see full answer. Accordingly, what does an Overseeder machine do?An overseeder or slit seeder is usually set to only cut into the soil an inch or less. This loosens the very top of the soil a bit, and it sure racks up the thatch in a lawn, but it is doing this so that the grass seed that is being dropped will likely fall onto moist loose soil and germinate.Secondly, can you put down too much grass seed? All plants, including grass plants, need adequate soil space for roots to spread and develop. If you put down too much grass seed, you will encourage competition that will cause your grass seedlings to struggle after germination because there will be excessive competition for sunlight, soil nutrients, and water. One may also ask, how does a grass seeder work? Power-seeding uses a machine that slices into the lawn, cutting a slit into the soil. The grass seed is then mechanically deposited into the soil. Aeration involves removing cores of grass and soil to allow water, air and nutrients to reach plant roots.When should I use an Overseeder?Late summer or early fall is the best time to overseed lawns. Soil and atmospheric temperatures are most favorable for optimum seed germination and growth. With adequate moisture, fertilizer and sunlight, the new seedlings will be well established before cooler fall weather sets in.
