Which tool would you use to prepare a lawn for seeding by removing thatch?

• A. Power Dethatcher
• B. Thatching Rake
• C. Power Aerator
• D. Rotary Spreader

Answer: (A)

Removing thatch to prepare the seedbed is the key idea here. Thatch is a dense layer of dead and living roots, stems, and other organic matter that sits between the soil and the green lawn. When that layer gets thick, it blocks seed-to-soil contact, traps moisture, and reduces air flow, making it harder for new grass to germinate and establish. A power dethatcher is designed to tackle this specifically: its rotating or spring-loaded tines comb through the turf, lift the thatch, and pull it up so you can remove it and expose the soil beneath. This creates a looser, cleaner surface with better seed-to-soil contact and moisture access, setting the stage for successful reseeding. After dethatching, it’s common to rake up the debris and then proceed with seeding. The other tools aren’t ideal for thatch removal: a manual thatching rake can work on small areas but is labor-intensive, a power aerator improves soil breathing and root growth but doesn’t remove the thatch effectively, and a rotary spreader is meant for distributing seed or fertilizer, not dethatching.
