How to Use the Greenworks Dethatcher
Using the Greenworks 10 Amp 14” Corded Electric Dethatcher is straightforward. Here are the general steps:
- Preparation:
- Make sure the lawn is dry and free of large debris.
- Adjust the dethatcher’s depth setting according to the thickness of the thatch.
- Plug the dethatcher into an outdoor extension cord (the tool is corded, so it requires a long enough cord to reach your yard).
- Operating the Dethatcher:
- Turn on the machine using the start switch.
- Push the dethatcher slowly across the lawn. It’s best to walk at a moderate pace to allow the tines to work properly.
- Depending on the thickness of your lawn’s thatch, you may need to go over areas multiple times.
- After Use:
- Collect the thatch material for composting or proper disposal.
- Turn off the dethatcher and unplug it before cleaning.
- Clean the tines and store the machine in a dry, cool place to prolong its lifespan.

Performance: What to Expect
The performance of the Greenworks 10 Amp 14” Corded Electric Dethatcher can be measured in a few key areas: power, efficiency, and ease of use.
Power & Efficiency
With its 10-amp electric motor, the dethatcher has enough power to tackle moderate to heavy thatch in small to medium-sized lawns. The 14-inch wide path ensures efficient coverage, allowing you to dethatch larger areas without needing to make too many passes.
Versatility of Stainless Steel Tines
The stainless steel tines are designed to offer long-lasting durability while being gentle on your lawn. The adjustable depth control allows you to fine-tune the tines’ operation based on the thickness of the thatch. In general, the dethatcher works well in lawns with 1/2″ to 1″ thick thatch.
Ease of Use
The ergonomic handle design adds comfort during use. The lightweight construction makes it easy to maneuver, even in tight corners. However, users might find it challenging to push the dethatcher over very thick, heavy thatch. For lawns with dense thatch, you may need to make multiple passes.
Noise Level
While not completely silent, the Greenworks dethatcher operates relatively quietly compared to gas-powered models. This makes it ideal for residential use, especially in neighborhoods with noise ordinances.
