Dethatchers come in a variety of types, including specialized dethatching rakes, electric dethatchers that resemble walk-behind lawn mowers, and tow-behind models that attach to the back of a lawn tractor or zero-turn mower. If you want a lush green lawn that’s the envy of your neighbors, you need a dethatcher in your arsenal of lawn care tools. We based our selections on several factors, including how effectively each dethatcher removes thatch, build quality, and ease of use.
