Questions worth asking
What is a brushless motor?
A brushless motor uses an electronic controller to switch the current in the motor windings, eliminating the need for carbon brushes. This results in higher efficiency, more torque, longer life, and less maintenance compared to brushed motors.
How do I choose the right voltage for my trimmer?
For light trimming around a small lawn, 18V-20V is sufficient. For medium yards with thicker grass, 40V is a good middle ground. For heavy-duty clearing, consider 56V or higher (like 80V) for maximum power.
Can I use my existing batteries from other tools?
Many trimmers are sold as ‘tool only’ to use with your existing battery system. If you already own tools from a brand like DeWalt, Milwaukee, or Ryobi, you can buy the trimmer only and use the same batteries. Ensure compatibility with the same voltage and platform.
How long does a battery last on a brushless trimmer?
Battery life depends on the amp-hour (Ah) rating and the load. A 2Ah battery might last 20-30 minutes, while a 4Ah battery can last 45-60 minutes under normal conditions. Using high power settings reduces runtime.
What is the difference between a bump feed and automatic feed trimmer head?
A bump feed head requires you to tap the head on the ground to release more line. An automatic feed head continuously advances the line as needed, but it can sometimes feed too much. Bump feed is more common and gives you control.
Are brushless trimmers worth the extra cost?
Brushless trimmers generally cost more upfront, but they offer better performance, longer battery life, and require less maintenance. If you use a trimmer frequently or have tough vegetation, the investment is worthwhile.
Can I convert a brushless trimmer into an edger?
Some models, like the WORX WG163 and Milwaukee M18 FUEL with QUICK-LOK, allow you to rotate the head to use as an edger. Others may require an attachment. Check the product specifications for edging capability.
What is the ideal cutting width for a residential yard?
For most residential yards, a cutting width of 15-16 inches is efficient. Wider widths cover more ground but can be heavier and harder to control in tight spaces. For small yards, 12-14 inches is sufficient.
How do I maintain a brushless trimmer?
Keep the trimmer clean, especially the air vents. Replace the trimmer line when it becomes short. Check for worn parts like the cutting head. Store the battery in a cool, dry place and charge it regularly. Because it’s brushless, there are no brushes to replace.
Do brushless trimmers have a longer lifespan?
Yes, brushless motors typically last longer because there are no carbon brushes to wear out. Additionally, they run cooler, reducing heat damage. With proper care, a brushless trimmer can last for many years.
The bottom line
For most homeowners, the EGO Power+ ST1623T is the best choice, offering a perfect blend of power, runtime, and ease of use. If you need a professional-grade tool with interchangeable attachments, go for the Milwaukee M18 FUEL. Budget-conscious buyers will appreciate the Greenworks Pro 80V, which includes a battery for a lower price. Choose the one that fits your yard size and budget.
