The lawn roller is used to flatten and compact the soil in lawns. The advantage of passing it is threefold: it allows seeds to be buried and optimal contact with the earth.
The weight of the roller also helps to eliminate bumps, irregularities and air pockets in the terrain. rolling the lawn repositions the blades of grass and encourages them to thicken to obtain an ever more beautiful and dense lawn. A small lawn roller weighs 30 or 40 kg, a large roll can exceed 100 kg, spread across the entire width to treat a large surface.
