Lawn scarifiers are garden tools designed to cut through the soil and aerate the lawns. The steel blades and wires located on the cylinder dig deep into the soil (up to 12 mm deep) and prune the lawn by helping to remove moss, thatch, and other debris like grass cuttings. This allows nutrients and water to reach the roots easier and makes the grass healthier and thicker.

Important parameters to keep in mind:
Working width - the larger the width, the larger the surface area the scarifier can process at once; a larger scarifier means you can get things get done faster.
Collector bag - thatch and debris gets collected immediately, so you don’t have to rake the lawn later.
Interchangeable blades - blades wear out eventually. A scarifier without interchangeable blades requires you to replace the entire cylinder, which is costly.
Seamless cutting depth control - lets you set the cutting depth more precisely.
Large wheels - are suitable for uneven surfaces.
