Common questions
What is the best battery voltage for a cordless edger?
For large yards, a 40V battery is a good starting point. It provides enough power for thick grass and soil. Higher voltage, like 56V, offers even more power but may add weight and cost.
How long does a cordless edger battery last?
Runtime varies from 20 to 60 minutes depending on battery capacity and load. Larger batteries (4.0 Ah or more) generally last longer. For very large yards, consider buying a second battery.
Can I use a cordless edger on thick grass and weeds?
Yes, but you need a powerful motor and a sharp blade. Models with higher voltage and torque, like the Greenworks 40V, handle thick growth better. Some edgers have a blade that can be rotated for different cutting depths.
Are cordless edgers as powerful as gas edgers?
Modern cordless edgers, especially 40V and above, can match the power of many gas edgers. They are quieter and require less maintenance. However, gas edgers may still have an edge for extremely tough, overgrown edges.
What is the difference between an edger and a trimmer?
An edger has a blade that cuts a clean, defined edge along sidewalks and driveways. A trimmer uses a spinning line to cut grass in tight spaces. For a crisp edge, an edger is the right tool.
Do I need a wheeled edger or a handheld one?
Wheeled edgers are easier to guide and produce straighter lines. Handheld edgers are more maneuverable but require more skill. For large yards, a wheeled edger reduces fatigue and improves accuracy.
Can I use an edger to create new edges?
Yes, many edgers can cut into soil to create new edges. Look for models with adjustable depth and a powerful motor, like the EGO. You may need to make multiple passes for a deep edge.
How do I maintain a cordless edger?
Keep the blade clean and sharp. After each use, wipe off grass clippings. Check the battery and charger for any damage. Store the edger in a dry place. Follow the manufacturer’s instructions for blade replacement.
Our take
If you need a cordless edger for a large yard, the Greenworks 12-Inch 40V is the best choice due to its wide cutting path and long runtime. However, if you already own DEWALT tools, the DEWALT 20V MAX XR is a smart addition. For maximum efficiency, consider the EGO 15-Inch, but be prepared for a higher price. Choose a model that balances power, runtime, and your budget to keep your edges looking sharp all season.
