10 Best Lawn Scarifier 2026 in the United States

The Greenworks 40V (2-In-1) Dethatcher / Scarifier is a versatile lawn care tool designed to help keep your yard healthy. This device is battery-powered, using a 40V lithium-ion battery, which offers the advantage of being cordless and easy to maneuver without the limitations of a power cord. The included 5Ah USB battery and rapid charger ensure that you can get back to work quickly after recharging.

Its 14-inch working width allows you to cover more ground efficiently, making it suitable for medium to large-sized lawns. The quick-swap tine reels are a standout feature, allowing you to easily switch between dethatching and scarifying tasks with minimal effort. The tines are made of stainless steel, which maintains sharpness longer, ensuring effective performance over time.

The depth adjustment feature is highly versatile, with 5-position settings ranging from minus 1/2-inch to plus 3/4-inch, allowing for customized lawn care based on your specific needs. However, at 35.3 pounds, the unit is on the heavier side, which might be a consideration for those who prefer lighter equipment. The removable grass collection bag is a convenient addition, helping to keep your lawn tidy by collecting debris as you work. The price point may be a bit high for some budgets, and the reliance on battery power means you need to ensure the battery is sufficiently charged before use. This product is best suited for homeowners with medium to large lawns looking for a reliable and convenient solution for dethatching and scarifying.

The Greenworks 13 Amp 14-Inch Corded Dethatcher / Scarifier is a versatile and powerful tool designed to help maintain a healthy lawn. Its corded electric power source provides consistent and reliable performance, eliminating the need to worry about fuel or battery life. The 14-inch working width is suitable for small to medium-sized lawns, making it efficient for homeowners with average yard sizes. The lightweight design, at 28.7 pounds, ensures that it is easy to maneuver, reducing user fatigue during extended use.

The 3-position tine depth adjustment feature allows for customization depending on the lawn's needs, helping to remove matted layers and promote healthy growth. Additionally, the quick release system enables easy switching between dethatching and scarifying functions, adding to its versatility. However, there are a few drawbacks to consider. The corded nature of the device means you will need access to an electrical outlet and may have to manage the cord during use, which could be less convenient than a cordless model. The product does not include a collection box, so you will need to manually rake up the debris, which could be an added chore.

While the lightweight design is beneficial for maneuverability, it might not be as durable or robust as heavier, more industrial-grade models. The Greenworks 13 Amp 14-Inch Corded Dethatcher / Scarifier is a solid choice for homeowners looking for an easy-to-use, reliable tool for maintaining their lawns, particularly for those who do not mind managing an extension cord and handling debris cleanup manually.

The SWIPESMITH Electric Dethatcher Scarifier offers a powerful 15 AMP motor and a generous 16-inch working width, making it efficient at removing debris and dead grass from your lawn.

Its 2-in-1 functionality, with both dethatching and scarifying blades made of stainless steel, promises durability and versatility.

The 5-position depth adjustment allows you to customize the working depth for different lawn conditions throughout the year, which is a valuable feature for maintaining a healthy lawn. Additionally, the adjustable handle height makes it suitable for users of different heights, enhancing usability. However, the 14.5-gallon collection bag might require frequent emptying if your lawn has a lot of thatch, which could be a bit inconvenient.

At 29.6 pounds, it's relatively lightweight for easy maneuverability, but it's still something to consider if you have limited strength. Safety features like the dual switches to prevent accidental starts add to its user-friendly design. While it is not a lawnmower, it is an effective tool for improving lawn health by removing debris and promoting thicker grass growth.
