The Best Dethatchers for Your Lawn Maintenance

To have a lush, green lawn of which you can be proud can often take a lot of hard work and attention to detail. If you’re looking for a faster result to having that great healthy lawn, dethatching might be the first step.

Thatch is the mat of dead grass clippings, leaf litter, and tree needles left behind throughout the season. The best dethatcher enables you to loosen the thick thatch that sits between the ground soil and the grass above which prevents new seedlings from emerging and growing. Removing that thatch also allows sunlight to penetrate and water to soak in to further promote a thicker, greener lawn. The best dethatchers can even remove moss to a degree. Keep reading to find out why the best dethatcher is worth adding to your lawn-care arsenal.

What to Consider When Choosing a Dethatcher

There are quite a few factors that go into choosing the best dethatcher. This section will outline some of the most important considerations to keep in mind while looking through the different options. This will help you find the best dethatcher for your lawn’s size and one that will pair well with existing lawn equipment.

Types of Dethatchers

Before you start shopping for the best dethatcher, it’s important to understand the different styles of dethatchers available. Each has its own pros and cons, so getting to know how each type works will help you to make a better decision on which is the best dethatcher for your needs.

Motorized 

Those with smaller yards and the desire to get in their fitness steps for the day might prefer motorized dethatchers. These look just like small lawn mowers, and they have motors that spin small dethatching tines that dig and loosen the thatch. 

Most motorized dethatchers are corded electric, so they require an outdoor power supply nearby or a long extension cord. They are best for small lawns or small areas that tend to need dethatching. On the plus side, they only require walking back and forth, so they’re easy to use. They’re also relatively low maintenance.

Tow-Behind 

If you have a large yard and a riding mower or a tractor, a tow-behind dethatcher could be an excellent addition to your lawn-care lineup. These dethatchers attach to the hitch on the back of a lawn mower, a tractor, a four-wheeler, or a side-by-side. As one of these motorized machines pulls the dethatcher across the lawn, it loosens up the thatch quickly and easily.

Tow-behind dethatchers are incredibly easy to use, requiring minimal effort once they’re properly attached. They can even be dragged behind a riding lawn mower to complete two jobs in half the time. A tow-behind dethatcher can be a bit challenging to store, since many models are as much as 4 feet wide.

Attachments

Like tow-behind dethatchers, attachments can turn other lawn tools such as lawn mowers into the occasional dethatcher. This can require a little bit of work, since the user has to replace mower blades with dethatching blades. Most attachments for mowers fit 20-inch decks. Check attachment information that comes from the dethatcher blade manufacturer for best results.

After using the push mower to dethatch the lawn, replace the dethatching blades with the original mowing blades and you are ready for regular lawn maintenance until the need to dethatch again. Purchasing a dethatching attachment not only saves on storage space but it’s also less costly than purchasing a thatching machine. 

Manual

If you don’t mind a bit of hard work, you can save substantial money and go for a manual dethatcher. This tool looks very similar to a standard yard rake, and it allows users to focus their efforts on small areas to ensure they can get to all the thatch.

Since they’re similar in size and shape to a rake, manual dethatchers take up little space and are ideal for small garages or workshops short on storage. They do require a bit more effort, so they’re most useful for small patches of compact thatch and smaller properties. 

Lawn Size

The size of the lawn might be the most significant consideration when shopping for the best dethatcher. Certain models are more than sufficient for a small yard, but they could easily fall short when dethatching an acre or two.

For tiny yards on tight city lots, a manual dethatcher is often the way to go. The tool is easy to store, and since there’s not likely to be a lot of thick thatch, it is more than sufficient for loosening up the dead grass and leaves.

For midsize properties up to an acre or two, a motorized dethatcher might be just the ticket. These units can dethatch a lawn quickly. Since most are electric, a nearby power source is a must.

For large properties, manual and motorized dethatchers just won’t do. If you have a few acres of land, a pull-behind dethatcher that attaches to a mower or a tractor is considerably more efficient at scraping up that thatch.

Motor Power

Dethatching is not a heavy-duty activity, and it doesn’t require a big, powerful machine to get the job done. The thatch layer of grass and leaf litter that sits within most lawns is easy for a typical dethatcher to disturb, so a basic electric motor will work. 

Generally speaking, these motors will have between 10 and 15 amps, with 15 amps being on the heavier-duty side of things. If a yard borders on the larger side of small, go with a higher amperage, which will do a better job of cooling the engine while running. A smaller property, however, doesn’t require more than 10 amps.

Tines

The tines are the small finger-like prongs that dig into the thatch and loosen it. The number of tines included on any dethatcher type typically depends on the width of the machine. As the tines rotate around the shaft (or get pulled through the yard), they dig into the thatch, lift it, and break it up.

The material of the tines also matters, since thatch is often damp and can cause corrosion of some materials. Stainless steel and spring steel tines are the best, since they’re both strong and can resist the effects of corrosion. Stainless steel is certainly the material to have for those preferring a low-maintenance tool.

Weight Capability 

Occasionally, you might want a dethatcher to dig a bit deeper into the thatch. This might be true if you’ve forgotten to dethatch in the fall, and winter’s snow has packed the grass clippings, tree needles, leaf litter, and small twigs into a thick mat. In those cases, a bit more weight can help give a dethatcher more bite.

Some tow-behind dethatchers can have weight added to them to help drive the tines deeper into tough thatch. If a light-duty dethatcher just isn’t getting the job done, consider moving to a tow-behind that can take a little extra weight.

Dethatcher Width 

When it comes to choosing the best dethatcher, keep in mind that the tools come in different widths. They range from about 12 inches to more than 48 inches wide, offering a variety of choices for small yards as well as large properties. 

The larger the dethatcher’s width, the fewer passes it will have to make to cover the property. But, if there are any narrow paths through the property, such as between trees or gates, it can be difficult to maneuver a larger dethatcher through. Consider the narrowest parts of the property before selecting a dethatcher.

Additional Features

There are a few additional features on some dethatcher models that might help make the decision easier. Many of the best dethatchers have adjustable heights to make the tines sink deeper into thick thatch or run higher and smoother over a thin type of grass. This can be a significant benefit to delivering good aeration, particularly if there are varying thicknesses of thatch throughout the lawn.

Some tow-behind dethatchers have levers that lift and lower the tines into the grass. This is a handy feature when crossing over driveways or pathways. The tines can be lifted without the user having to get off the tractor and then lowered back down when clear from the pavement or concrete.
