Part of having a great-looking lawn is making sure the soil is healthy so that the entire lawn can thrive. One of your jobs in accomplishing this is to get rid of any thatch that has become part of your soil. Thatch is located between the soil and the grass and can stunt the growth of the grass if left there too long.

A de-thatching machine will get rid of the thatch so that the soil can be healthier and will let in more water and nutrients. The good news is that these de-thatchers work much the same as regular lawnmowers, so they are super easy to use.

Since Sun Joe and Greenworks both make great de-thatching machines, let’s take a look at the two of them and see how they compare.

Like a lawnmower, this de-thatcher comes with a collection bag that collects the thatch so that you can easily dispose of it afterwards. It is easy to operate and is 15 inches wide to cover large areas of lawn at a time, which means that the entire de-thatching job can be done quickly.
