Gas String Trimmer
Unmatched power and runtime for large properties and thick vegetation.
Check priceElectric String Trimmer
Quiet, low-maintenance, and eco-friendly for typical suburban yards.
Check priceIf you have a large yard (over half an acre) with thick brush, a gas trimmer gives you the power and run time you need. For most homeowners with small to medium yards, an electric trimmer is quieter, cleaner, and easier to maintain. Choose based on your yard size, physical comfort, and willingness to handle fuel and maintenance.

Quick questions
Which is better for a small yard, gas or electric?
For a small yard, electric is almost always the better choice. It is lighter, quieter, and requires no fuel mixing or engine maintenance. A corded electric trimmer offers unlimited run time for small spaces, while a cordless model with a 40V or higher battery can easily handle typical small yard work on a single charge.
How long does an electric string trimmer battery last?
Battery run time varies by voltage and amp-hour rating. Standard 20V models may last 15-25 minutes, while 40V and 60V models can run 30-60 minutes on a full charge. Higher capacity batteries (e.g., 5.0Ah) extend run time. For larger yards, consider buying a spare battery or a model with a rapid charger.
Are gas string trimmers being phased out?
Some states and municipalities are restricting gas-powered lawn equipment due to emissions, but there is no nationwide ban. Gas trimmers are still widely available and legal in most areas. However, the trend is toward electric, with many manufacturers expanding their battery-powered lines. Check local regulations before buying.
