What to look for
Battery Voltage and Runtime Higher voltage usually means more power. For large yards, look for 40V or higher. Check the amp-hour (Ah) rating for runtime. A 5Ah battery lasts longer than a 2Ah. Some trimmers allow swapping batteries, which helps if you have multiple packs.
Cutting Swath and Line Feed A wider cutting swath (15 inches or more) covers more ground quickly. The line feed system matters: bump feed requires tapping the head, while automatic feed advances line hands-free. Dual line heads cut faster but may tangle more.
Motor Type and Torque Brushless motors are more efficient and durable than brushed motors. They provide better torque for thick weeds. Look for variable speed triggers to control power. Some models have a high-torque mode for tough jobs.
Comfort and Ergonomics Trimming a large yard can take over an hour. Choose a model with a comfortable grip, adjustable shaft, and good balance. Weight matters, but a heavier trimmer with a harness can reduce fatigue. Consider models with vibration dampening.

Frequently asked questions
How long does an electric string trimmer battery last?
Runtime ranges from 20 to 60 minutes depending on battery size and load. For large yards, a 5Ah battery can last about 45 minutes. Always check the included battery capacity.
Can electric trimmers handle thick weeds?
Yes, high-voltage models with brushless motors and dual line can cut through thick growth. However, they may struggle with very woody stems. Use a blade attachment for heavy brush if needed.
Are electric trimmers as powerful as gas ones?
Modern electric trimmers, especially 80V and 60V models, rival gas in power. They are quieter, start instantly, and require less maintenance. For most residential yards, they are more than sufficient.
What size battery do I need for a large yard?
For large yards, aim for a battery with at least 4Ah. Some trimmers come with a 5Ah battery. If not, you may need a second battery to finish the job.
How do I feed new line on a bump feed trimmer?
Tap the trimmer head on the ground while it spins. The line will advance. Some models have a button to manually pull line. Always use the correct line diameter specified by the manufacturer.
Can I use attachments with electric trimmers?
Some brands offer attachment systems. Ryobi and Craftsman have expandable shafts. Others are dedicated trimmers. Check compatibility before buying attachments.
Are corded electric trimmers better for large yards?
Corded models provide unlimited runtime but limit range. For large yards, you may need extension cords, which can be cumbersome. Battery-powered trimmers offer more freedom, though with runtime limits.
How often should I replace the trimmer line?
Line wears out with use. You may need to replace it when it becomes too short or breaks. Using quality line reduces breakage. Automatic feed systems use line faster, so keep extras on hand.
Do electric trimmers require much maintenance?
They require minimal maintenance. Keep the air vents clean, check for debris, and store the battery properly. Unlike gas, there is no fuel mixing, spark plugs, or air filters to worry about.
What is the best electric trimmer for a sloped yard?
Look for a lightweight model with a comfortable grip. A trimmer with a curved shaft may be easier to handle on slopes. The EGO and Greenworks models offer good balance and power.
The bottom line
For most large yards, the EGO Power+ ST1623T offers the best combination of power and runtime. If you are on a budget, the Greenworks Pro 80V is a solid choice that still handles big areas. For those needing multiple tools, consider the Ryobi expand-it system.
