The VGR TopChanger™ combines the actions of water injection and sand filling in one efficient action. It weighs only 680kgs, has a working width of 1.60m and produces a closely spaced adjustable row of holes using adjustable water pressure which delivers sand and, or water including water mixed with chemicals i.e. nematicides or wetting agents etc… This allows a path for water to penetrate the top layer(thatch) of soil and be absorbed directly into the root zone to encourage rapid growth and healthy development of the grass, and over a period of time changing/amending the growing medium.
