Taking care of your lawn is no easy task. There is only so much you can do to grow healthy and even grass on your lawn. But, you will still find abnormal growth rate and non-uniform grass in your lawn that requires your attention. To fix these problems, you will require special tools such as a lawn dethatcher. A lawn dethatcher can help you take care of your lawn and personalize the grass according to your will. Here are some things to keep in mind before you buy a lawn dethatcher.

  • Type of Dethatcher: There are essentially two types of dethatchers that are electrically powered, and tow behind one’s that need to be mounted behind a vehicle. We will only recommend you to go with the toe behind options if you have a large backyard and already own a heavy vehicle.
  • Working Width: The working width represents the amount of thatch it can collect at a time. The larger the width, the more thatch you can collect in one go. But, you should consider available space in your lawn and make sure the working width of the dethatcher fits your area before you buy one.
  • Warranty: It is impossible to keep your detacher safe from dust, dirt, and impurities. Thus, you should have a long warranty period on your unit. In case something were to happen to your dethatcher, you can claim free service and repairs.

Buying Guide For The Best Lawn Dethatcher

Thatch is a collective term for dead leaves, dead grass, roots, and stems which form a thick layer over the grass and eventually cover the grass completely. Thatch is naturally grown in every grass lawn, and it is impossible to avoid it. Although, you can quickly get rid of the thatch by using a decent detacher.

If so, take a look at our buying guide for the best lawn dethatcher, which will help you to choose a perfect option from our list.

Handle Size and Ergonomics

All hand-operated tools need to be thoroughly checked for the ergonomics of the shape and design of the handles. You are going to be holding on to these handles for quite some time in each session. If these handles are not optimized for the best comfort, you will feel strain in your hands which is not a good sign for long-term use. In the case of lawn dethatchers, manufacturers provide a special comfortable grip on the handle that is soft on the hand while providing a secured grip on the device. It is important in all electrically powered lawn dethatchers.

Size of The Lawn

The effective coverage area of your lawn dethatchers is dependent upon the size and grass type of your lawn. For regular backyard lawns with naturally grown grass, you shall not require a heavy-duty device. Instead, you should save some money and prefer a budget option that will satisfy your needs for the time being. In the case of commercial application, you should prefer a large working width as it would cover a larger surface area of the lawn in every cycle. Also, the performance and durability of the tines change with the type of lawn dethatcher.


Coming to the most important part of the lawn dethatcher, the durability of the tines. The small yet sharp and flexible tines present on the lower section of the lawn dethatchers are the most important part of the device as they are responsible for cleaning your garden.

The more effective the pines are, the more thatch and dirt you can remove in every single pass. The durability of these lawn dethatchers is directly dependent upon the quality of the pines as well as the overall build quality of the dethatcher. To be extra safe, you should buy a variant that offers a long warranty period for added benefits.

Power Type

You can either buy a self-powered electric dethatcher or a mountable tow behind the type of dethatchers to get rid of thatch from your lawn. Even in the case of electric dethatchers, you will be faced with a choice of corded or cordless options.

Generally, two behind options should only be preferred if you own a powerful tractor or a truck that you can use to detach your lawn with the tow behind the lawn dethatcher. In the case of electrical dethatchers, you should make sure that you have a suitable power supply outlet available on your lawn so that you won’t have to buy an extended cord later on. A cordless device is suitable for compact lawns with short grass.
