A dethatcher is a tool for outdoor use that is used to break up and remove a built-up layer of thatch from your lawn (Source).
Thatch is the compressed dead plant matter that builds up at the base of your lawn overtime. It can be made up of roots, stems, and runners (Source).
It can be beneficial to the health of your lawn but when it gets too thick, it poses a serious risk to the long-term health of your lawn and it’s probably time to consider dethatching your lawn (Source).
Dethatchers work by using strong tines to break up and pull up the layer of thatch in a lawn. Some dethatchers have catch bags to collect the thatch for easy disposal. Being able to easily collect the thatch that is pulled up helps give your lawn a cleaner look right away.
Should You Dethatch?
There are different ways that a dethatcher can work. Some are electric and corded, some are gas powered, and some are towed behind your lawn mower (the Mantis and Agri-Fab).
Many buyers suggested that when using electric dethatchers that you should consider a heavy-duty extension cord to ensure proper function of your electric dethatcher (Source).
Buyers with a pull behind dethatching rake suggest that you use a good amount of weight on the pull behind dethatching rake the first time that you go over your lawn, and also that you be sure to very securely attach the weight to the pull behind dethatching rake (Source).
How They Compare
The Greenworks, Van Haus, and Sun Joe dethatcher rakes are all corded electric dethatchers. Whereas both the Argi-Fab and Mantis are dethatching attachments.
The Mantis dethatcher attaches to any Mantis tiller, and the Argi-Fab is a pull behind dethatching rake also known as a tow behind dethatcher. It hooks to the back of a lawn mower and is towed across the lawn.
The Van Haus dethatcher and the Sun Joe dethatcher both have a width of 13 inches and include catch bags to collect the thatch for easy disposal. The other three dethatching machines on the list don’t include catch bags but all have larger widths.
The Greenworks dethatcher has a width of 14 inches, the Mantis dethatching attachment has a width of 15 inches, and the Argi-Fab dethatcher has an impressive width of 48 inches.
The Greenworks dethatcher also features a nice ergonomically designed padded grip on the handle for maximum comfort, while the Van Haus electric dethatcher has a height adjustable handle that allows for comfortable dethatching of your lawn regardless of your size.
How to Use a Dethatcher
- Follow the instructions from the manufacturer of your dethatcher to perform any needed assembly and prep your dethatcher for use.
- Before you get started dethatching, it’s best to mow your lawn. Mowing your grass shorter than you typically do will help the dethatching process to go more smoothly.
- Run your dethatcher over the entire lawn going in the same direction. For best results, run the dethatcher over the lawn again going at a 90-degree angle to the first direction you went.
- If your dethatcher has a catch bag, you’ll need to empty it each time it fills up. If your dethatcher does not have a catch bag, you will probably want to rake up all of the loose thatch after you finish dethatching.
- It’s a great idea to water your yard right after dethatching. You may also want to take this opportunity to spread fresh grass seed and fertilizer throughout your lawn.
