The countryman aerator has a carbon steel tubular frame and handle with five hollow tines, designed to create holes in the soil in which lawn grasses grow. Aeration involves perforating the soil with small holes allowing air, water and nutrients to penetrate the the grass roots.
This helps the roots grow deeply and produce a stronger, more vigorous lawn. Aeration alleviates soil compaction, improves soil drainage and encourages worms, microfauna and microflora which all require oxygen. Soil aeration tools do not remove weeds but prepare the soil for better growth.
