10 Best Dethatchers 2025 in the United States

The Greenworks 40V 15 inch Dethatcher/Scarifier is designed for homeowners looking to maintain a healthy lawn, particularly for those with cool-season and warm-season grasses. Its 2-in-1 functionality allows users to easily switch between dethatching and scarifying, making it versatile for various yard care tasks. With a 14-inch dethatching width, it helps you cover more ground and finish jobs faster, which is a significant advantage for those managing larger lawns.

One of its standout features is the adjustable depth settings, offering five positions, allowing users to customize the depth according to their lawn's needs. The stainless steel tines are durable and maintain sharpness over time, which enhances efficiency during use. Battery power adds to its appeal by providing mobility without the hassle of cords, making it easier to maneuver around your yard.

There are a few drawbacks to consider. Weighing 26.45 pounds, it may be a bit heavy for some users, especially when maneuvering on uneven terrain. Additionally, while the battery power is convenient, you may need to ensure that it has adequate charge for larger areas since the runtime can vary based on usage. The absence of a collection bag may also be a downside for those who prefer to gather debris as they work, making cleanup a bit more labor-intensive.

The Greenworks 13 Amp 14-Inch Corded Dethatcher/Scarifier, DT13B00, stands out with its 2-in-1 design, allowing users to switch between dethatching and scarifying with ease. This versatility is beneficial for maintaining a healthy lawn throughout different seasons. Its 13-inch working width is modest but effective for small to medium-sized yards. The 3-position tine depth adjustment is a useful feature for managing different layers of thatch, promoting healthy lawn growth.

However, it lacks a collection bag, meaning extra cleanup work post-operation. The product is lightweight at 28.7 pounds, making it easy to maneuver, and the easy push-button start adds to its user-friendly design. It operates with a corded electric power source, which ensures consistent power but limits mobility due to the need for an extension cord.

Despite these limitations, it has received positive customer feedback with a 4.5-star rating from 970 reviews. This makes it a reliable choice for homeowners looking to maintain their lawns without investing in a more expensive, heavy-duty machine.

The TIECTOWN 16-Inch 15.5 Amp 2-in-1 Electric Dethatcher and Scarifier is designed to offer versatile lawn maintenance with its dual functionality. It combines both dethatching and scarifying blades, allowing you to switch between these functions easily, which can help improve soil aeration and grass health effectively.

The device provides a working width of 16 inches, which is suitable for medium-sized lawns, and its 5-position depth adjustment helps cater to different lawn heights and seasonal needs. This feature ensures optimal performance whether you are removing dead grass or loosening soil for better root growth. The dethatcher’s lightweight design (30 lbs) makes it easy to maneuver and operate, and the foldable handle facilitates compact storage, ideal for homeowners with limited storage space or who prefer a hassle-free setup and takedown.

Additionally, the 14.5-gallon removable collection bag simplifies debris disposal, although it may require frequent emptying during heavy-duty tasks. The powerful 15.5-amp motor ensures efficient operation, reaching speeds up to 3600 RPM, which can save time and energy in lawn care. Practical features like the waterproof plug, cord clip, extension cord holder, and wear-resistant wheels enhance convenience and safety. However, its primary use is for dethatching and scarifying, not mowing, which means users need a separate tool for regular mowing tasks. The 24/7 after-sales support adds a layer of reliability. This dethatcher/scarifier is well-suited for homeowners looking for a powerful, easy-to-use tool to maintain a healthy lawn.
