20V or 60V Trimmers Compared
Voltage and Power
The WORX WG931 operates on a 20V platform, which is part of the broader Power Share ecosystem compatible with other 20V and 40V tools. This lower voltage system is designed for light to moderate yard work and offers versatility across a multi-tool kit. In contrast, the Greenworks ST60L254 uses a 60V system with a brushless motor delivering 6000 RPM. The higher voltage provides power equivalent to a 26cc gas trimmer, allowing it to tackle thicker vegetation like blackberry vines and kudzu. The 60V system delivers significantly more cutting torque for demanding tasks.
Cutting Width
Cutting swath determines how much grass you clear with each pass. The WORX WG931 features a 12-inch cutting width. This narrower profile offers better maneuverability in tight spaces, such as around garden beds or narrow pathways. The Greenworks ST60L254 provides a 16-inch professional swath. This wider cutting path allows you to clear larger areas, like fence lines or open lawns, more efficiently. The extra four inches reduces the number of passes needed to cover the same ground, making the Greenworks better suited for larger properties.
Line Feed System
How the trimmer reloads string affects your workflow. The WORX WG931 uses a command feed system. You push a button to release more line when it runs short. This model also includes free replacement spools for life. The Greenworks ST60L254 features a spin-to-load head design. You reload .095-inch line in about 10 seconds by twisting the housing and pulling. This method saves approximately 15 minutes compared to traditional bump-feed heads. The Greenworks approach eliminates manual winding, offering a faster and cleaner reloading process.
Battery Capacity
Battery capacity influences runtime between charges. The Greenworks ST60L254 includes a 2.5 Ah battery. This capacity allows for up to 1.5 acres of mowing per charge and recharges in 45 minutes. The WORX WG931 product data does not specify a battery capacity for this specific kit configuration. The variations list shows options with batteries, but the exact amp-hour rating for the included power source is not explicitly stated in the key specs. Without this data, we cannot directly compare the runtime capabilities of the WORX battery versus the Greenworks 2.5 Ah unit.
Versatility and Kit Contents
The WORX WG931 is sold as a 3-in-1 kit. It includes a 12-inch trimmer/edger, a 22-inch hedge trimmer, and a 360 CFM blower. This bundle allows you to trim, edge, hedge, and blow leaves using the same battery platform. The Greenworks ST60L254 is listed as a standalone string trimmer. While the brand offers combo kits, this specific model focuses solely on trimming. If you need multiple yard tools, the WORX kit provides immediate variety. If you only need a dedicated trimmer, the Greenworks offers a specialized tool without extra attachments.
Weight and Balance
Weight impacts user fatigue during extended use. The Greenworks ST60L254 weighs 11.2 pounds with the battery. It features a 360-degree rotating handle that reduces wrist strain by 40 percent, offering better balance for detailed work. The WORX WG931 kit weighs 17.7 pounds. This higher weight includes the trimmer, hedge attachment, and blower components bundled together. The additional mass may require more effort to maneuver, especially when holding the tool overhead or for long periods. The Greenworks design prioritizes lighter weight and ergonomic balance.
Which Trimmer Fits Your Needs?
Homeowners wanting a multi-tool kit
The WORX WG931 bundles a trimmer, hedge trimmer, and blower into one system. Its 20V platform shares batteries across tools. The 12-inch cutting swath and command feed system simplify maintenance. You get three tools for the price of one, reducing clutter and storage needs for general yard upkeep.
Users tackling thick overgrowth
The Greenworks ST60L254 uses a 60V brushless motor delivering 6000 RPM. This power handles thick vines and stubborn weeds. The 16-inch professional swath cuts wider paths. The spin-to-load head reloads line quickly. You gain efficiency and cutting power for tougher vegetation that lower voltage tools might struggle to clear.
Those prioritizing lightweight handling
Weighing just 11.2 pounds with the battery, the Greenworks trimmer reduces wrist strain. Its 360-degree rotating handle allows comfortable positioning. The brushless motor ensures efficient power delivery. You benefit from better balance and reduced fatigue during extended use, making it easier to maneuver around flower beds and tight spaces.

Frequently asked questions
Is 20V enough for a small yard?
Yes, 20V systems handle light to moderate yard work well. The WORX WG931 kit provides a 22-inch cutting width and weighs 17.7 pounds. This makes it easy to maneuver in tight spaces. It is ideal for small yards where a 12-inch cut width is sufficient. The system includes a trimmer, hedge trimmer, and blower for versatile use.
Can a 60V trimmer cut thick weeds?
Yes, 60V models deliver robust power for heavy-duty tasks. The Greenworks ST60L254 is designed for thick overgrowth and wide cutting paths. It features a 16-inch cutting width to clear more grass per pass. This higher voltage platform offers the torque needed for dense vegetation that might stall lower voltage tools.
How wide is the cutting path on these trimmers?
Cutting widths vary by model and voltage class. The WORX WG931 offers a 22-inch cutting width, which is generous for a 20V tool. The Greenworks 60V model provides a 16-inch cutting width. A wider path allows you to clear more area with each pass, reducing total mowing time for larger lawns.
What is the weight difference between 20V and 60V trimmers?
Weight affects fatigue during extended use. The WORX WG931 kit weighs 17.7 pounds. The Greenworks 60V trimmer does not list a total weight in its specs, but 60V batteries are generally heavier. Consider the weight distribution and handle length when choosing. The WORX unit is 36.3 inches long, while the Greenworks is 68.5 inches long.
Do these tools use the same batteries?
No, they use different voltage platforms. The WORX WG931 uses a 20V battery, part of the Power Share ecosystem. The Greenworks ST60L254 uses a 60V battery with a 2.5 Ah capacity. You cannot swap batteries between these systems. Check if you already own batteries for the specific voltage you plan to buy.
Is a 3-in-1 kit worth the space?
A 3-in-1 kit saves storage space and offers versatility. The WORX WG931 includes a trimmer, hedge trimmer, and blower. This is ideal if you need multiple tools but want to share one battery type. It is best for small yards. If you only need trimming power, a single 60V tool might be more efficient for heavy duty tasks.
What battery capacity do I need for 60V?
Battery capacity determines runtime. The Greenworks 60V trimmer uses a 2.5 Ah battery. Higher Ah ratings provide longer run times. For thick overgrowth, a robust power source is crucial. The 60V platform delivers more power than 20V, but runtime depends on the specific battery pack you attach to the tool.
