How to choose attachment trimmers
-
Match your battery voltage
Check which voltage platform you already own. The Greenworks 60V and 80V models fit that ecosystem, while RYOBI offers 18V and 40V options. DEWALT uses 60V. Using your existing batteries saves money and reduces clutter. If you lack batteries, choose a kit that includes them. The Greenworks 60V comes with a 4.0Ah battery. The Husqvarna FLXi includes a 4.0Ah pack. The RYOBI 40V tool-only version requires separate purchase. Align your choice with your current inventory to ensure immediate usability without extra costs.
-
Select the cutting width
Cutting width determines how much area you clear per pass. Wider decks cover more ground faster. The DEWALT 60V offers a 17-inch width, the largest here. The Greenworks 60V and 80V both provide 16-inch paths. The RYOBI 40V and 18V models feature 15-inch widths. The Prorun 60V has a narrower 13.2-inch cut. Choose a wider deck for large, open yards. Select a narrower deck for tight spaces around trees or fences. Match the width to your typical trimming needs for efficiency.
-
Consider the motor type
Brushless motors offer longer life and better efficiency. They require less maintenance than brushed versions. The Greenworks 60V and RYOBI 18V models use brushless technology. The DEWALT 60V and RYOBI 40V HP also feature brushless drives. Brushless motors maintain power as the battery drains. They run cooler and quieter. If you plan to use the tool frequently, prioritize brushless options. Check the attributes for motor type. Avoid brushed models if you want minimal upkeep and consistent performance over time.
-
Check included battery capacity
Battery capacity affects runtime. Higher amp-hour ratings provide longer operation. The Greenworks 60V includes a 4.0Ah battery. The Husqvarna FLXi also includes a 4.0Ah pack. The Greenworks 80V comes with a smaller 2.5Ah battery. The RYOBI 40V tool-only version has no battery. The RYOBI 18V kit includes a 4.0Ah unit. If you need extended trimming sessions, look for kits with higher capacity. Ensure the included battery matches your workload. Smaller capacities may require frequent swapping or recharging during large jobs.
-
Evaluate tool weight
Weight impacts comfort during extended use. Lighter tools reduce fatigue. The Husqvarna FLXi weighs just 10 pounds. The RYOBI 40V tool-only model is also light at 11 pounds. The DEWALT 60V weighs 15 pounds. The RYOBI 40V with battery weighs 13.9 pounds. Heavier tools may feel stable but cause arm strain. If you trim for long periods, choose a lighter option. Check the specs for weight. Balance weight with battery size. A lighter tool with a large battery may still feel heavy.
