What matters most

Questions worth asking

How long does a cordless string trimmer battery last?

Battery runtime varies by model and conditions. On average, you can expect 30 to 60 minutes of continuous use. Higher capacity batteries (4Ah or more) provide longer runtime. Thick grass and high power settings drain batteries faster.

Can I use one battery for multiple tools?

Many brands share batteries across their tool lines. For example, EGO, Ryobi, and DeWalt offer systems where the same battery fits various tools. This is convenient if you already own tools from the same brand.

What is the best cutting width for a large yard?

A wider cutting width covers more ground per pass, reducing time. For large yards, look for trimmers with a 15 to 17 inch swath. This allows you to finish faster, but consider the added weight and power requirements.

Are brushless motors worth the extra cost?

Brushless motors are more efficient, durable, and provide more power than brushed motors. They also run cooler and have a longer lifespan. For large yards, a brushless motor is a wise investment.

How do I replace the trimmer line?

Most trimmers have a bump feed or automatic feed system. To replace, remove the spool, insert new line, and wind it according to the directions. Some models have a quick-load feature that simplifies the process.

What is the difference between a string trimmer and a brush cutter?

String trimmers use flexible line to cut grass and weeds. Brush cutters use a metal blade for thick brush and small saplings. For typical lawn maintenance, a string trimmer is sufficient, but if you have heavy brush, consider a brush cutter attachment.

Can I use a cordless trimmer for edging?

Yes, many cordless trimmers have a rotating head that allows you to turn the cutting head 90 degrees for edging along sidewalks and driveways. Check the product specifications to see if it offers this feature.

How should I store my cordless trimmer in winter?

Clean the trimmer thoroughly, remove the battery, and store it in a dry place. Charge the battery to about 50% and store it separately. This prevents damage from freezing and preserves battery health.

Our pick

For most large yards, choose the EGO Power+ ST1623T for its superior runtime and power. If you have heavy brush, go with the DeWalt DCST972X1 for its torque. For budget-conscious buyers, the Ryobi 40V brushless offers the best balance of price and performance.
