Grass and roots need Oxygen. Regular aeration is important to get this Oxygen right to the part of the grass where it needs it most: at the roots. MAREDO found a quick and efficient way to aerate grass and designed the MAREDO MT210 VibeSpike-Aerator. The unique system of vibratory spike sections helps reaching a working depth up to 60mm. The vibrating spikes will also relieve soil compaction and help stimulate healthy grass growth.
