This lawn aerator is extremely easy to assemble. You only need to connect and tighten the 3 tubes to complete the assembly of the handle. Then, by tightening the fasteners, you can connect the handle to the roller. The whole process can be smoothly completed within just a few minutes, and your lawn aerator is ready for use.As a professional tool, it can effectively enhance the aeration and drainage of the soil, promote the vigorous growth of the lawn roots, and improve the plants' ability to absorb water and nutrients. Over time, daily walking, trampling, and the use of heavy equipment can lead to soil compaction, which seriously hinders the growth and development of the lawn. However, this lawn aerator reduces soil compaction by punching holes in the soil, decreasing its density, and allowing air, water, and nutrients to penetrate more smoothly into the root zone.Meanwhile, the good aeration and drainage conditions enable water to quickly infiltrate and distribute in the soil, reducing surface water accumulation and lowering the risks of surface runoff and waterlogging. Compared with other mechanical operations, it is both environmentally friendly and cost-effective. It will not cause any damage to the soil or plants and can also reduce the need for expensive lawn repair work.
