Pluggers are the ideal machines for reseeding lawns as well as allowing moisture and air to get to the roots. The 15 inch drum which can be filled with water has heavy 4 inch spoons welded on the drum to pull a plug of soil out of the ground. This hole provides a water pocket for better water and fertilizer absorption to the underlying root system. The plug hole will then loosen the surrounding soil and re-fill with soil to uncompact the crust on top of the lawn.
