Specifications side by side

How to choose the right Greenworks trimmer

1. Check voltage for power

   Voltage determines the motor's potential output. Higher voltage systems generally deliver more torque for tough jobs. The Greenworks 82V Cordless Lawn Edger offers the highest voltage in this guide, providing commercial-grade power for heavy-duty edging tasks. In contrast, the 40V models are lighter and sufficient for standard lawn maintenance. You should match the voltage to the density of your vegetation. If you have thick brush, a 60V or 82V system is preferable. For simple grass trimming, a 40V unit provides adequate performance without the extra weight.

2. Select cutting width wisely

   Cutting width affects how many passes you need to finish your yard. Wider decks cover more ground per stroke. The 16-inch models, such as the Greenworks 60V 16-Inch String Trimmer and the 40V variant, are ideal for medium to large yards. They reduce the time spent mowing. Smaller widths, like the 13-inch or 8-inch options, offer better maneuverability in tight spaces. You should choose a wider deck if you prioritize speed. Select a narrower deck if you need precision around garden beds or obstacles. Match the width to your yard size for efficiency.

3. Consider motor type

   Motor type influences runtime and maintenance needs. Brushless motors are more efficient and durable than brushed ones. They require less maintenance and offer longer tool life. The Greenworks 48V 17-Inch Brushless Lawn Mower features this technology for reliable performance. You should look for brushless motors if you plan to use the tool frequently. They provide consistent power as the battery drains. Brushed motors are often found in budget-friendly options. They are suitable for occasional use. Check the specifications to see which motor type each model uses before deciding.

4. Evaluate weight and size

   Weight impacts comfort during extended use. Lighter tools reduce fatigue. The Greenworks 40V 16-Inch String Trimmer weighs only 15.2 pounds, making it easy to handle. Heavier tools, like the 82V Edger at 28.2 pounds, offer more power but require more strength. You should consider your physical comfort when choosing. If you have back issues, a lighter model is better. Check the length and width specs for storage considerations. Longer tools may be harder to store in small sheds. Match the physical dimensions to your storage space and handling ability.

5. Look at combo kits

   Combo kits provide multiple tools for one price. The Greenworks 40V 16 in Trimmer & Blower Combo includes a blower with 550 CFM air volume. This kit allows you to trim and clear debris without switching batteries. You should consider these if you want versatility. They save money compared to buying tools separately. The 60V 13-Inch Trimmer 3-Tool Combo also offers extended runtime with multiple batteries. Check the included accessories and battery count. Ensure the kit meets your specific yard care needs. These options are practical for homeowners who want a complete tool set.
