Good to know
How long does a brushless string trimmer battery last?
Runtime varies by voltage and amp hour. For example, a 56V 2.5Ah battery can last about 30 minutes on high. For large yards, consider higher capacity batteries or spares.
Can I use a brushless trimmer for thick weeds?
Yes, brushless motors provide high torque. Models with higher voltage and RPM, like the EGO or Milwaukee, handle thick weeds more effectively. Use a heavier line if needed.
Are brushless trimmers worth the extra cost?
Brushless trimmers usually cost more upfront but offer better performance and longevity. They are more efficient and have fewer maintenance issues than brushed motors.
What cutting width is best for a large yard?
A wider swath reduces trimming time. Look for 16 to 17 inches for large areas. Some models like the Greenworks Pro offer 17 inches.
Do I need to buy a battery and charger separately?
Many pro-grade trimmers are sold as bare tools. Check the product description. Some brands include batteries and chargers, like the Greenworks Pro and Craftsman models.
How does the line feed system work?
Bump feed requires you to tap the head on the ground to release more line. Auto feed releases line automatically when needed. Both work well, but bump feed is often more durable.
Are electric brushless trimmers quieter than gas?
Yes, brushless trimmers are significantly quieter. They are also lighter and require less maintenance. The Ryobi Whisper is particularly quiet.
Can I use these trimmers for edging?
Many models have a rotating head that allows you to flip the trimmer for edging. The EGO and Ryobi models offer this feature. Check specifications for a pivoting head.
What is the warranty on brushless trimmers?
Warranty varies by brand. Typically, you get 2 to 5 years on the tool and battery. EGO offers a 5-year warranty on the tool and 3 years on the battery.
How do I store the trimmer?
Store the trimmer in a dry place. Remove the battery when not in use. Some models have folding shafts for compact storage.
Our take
For most large yards, the EGO Power+ ST1623T offers the best balance of power and features. If you are on a tighter budget, the Greenworks Pro 80V gives you a wide cut and includes battery. Both are solid choices that will handle a big property without the hassle of gas.
