Deep-Tine Aeration with Verti-Drain

An aeration method uses solid tines to create deep holes into the turf without removing any soil. The Verti-Drain insert a tine that kicks to gently lift and shatter the soil in a uniform manner to further break up compaction and create space in the soil profile for air, water, and grass plant roots.

The world-renowned Verti-Drain aerator was invented by Redexim more than 40 years ago. It has changed the method of soil aeration across the world, becoming the ‘must use’ for turf managers in their battle to aid turf growth in challenging environments.
