RYOBI vs WORX Trimmer Specs
Voltage and Power
The RYOBI 40V string trimmer operates at 40 volts, while the WORX kit uses a 20V system. Higher voltage typically translates to more torque and sustained power under load. The RYOBI claims to deliver more power than a 21cc gas trimmer, suggesting it can handle thicker weeds with ease. The WORX 20V platform is designed for lighter to medium-duty tasks. If you have large, overgrown areas, the higher voltage of the RYOBI may provide the necessary cutting force. The WORX relies on its 360 CFM blower for debris management rather than raw trimming torque. You should choose the RYOBI if you prioritize maximum cutting power.
Cutting Width
Cutting width determines how much grass you clear in a single pass. The RYOBI features a 15-inch cutting swath, which is wider than the 12-inch swath of the WORX trimmer. A wider cut means you can cover ground faster, reducing the time spent on large lawns. The WORX 12-inch width is standard for many residential tools but requires more overlapping passes. The RYOBI’s extra three inches adds up over many minutes of mowing. This spec is a clear advantage for efficiency if your primary goal is trimming wide expanses of grass. The WORX compensates with additional tools, but for pure trimming width, the RYOBI leads.
Versatility and Kit Content
The WORX WG931 is a 3-in-1 kit that includes a trimmer, a 22-inch hedge trimmer, and a turbine blower. This bundle offers significant versatility for different yard tasks. The RYOBI is a bare tool string trimmer only, though it is attachment capable. The WORX hedge trimmer has dual-action blades for efficient cutting, and the blower reaches 75 MPH. The RYOBI requires separate purchases for attachments, which adds cost and complexity. If you need to trim hedges or blow leaves without buying extra tools, the WORX kit provides immediate value. The RYOBI is better only if you already own compatible attachments.
Shaft Type and Compatibility
The RYOBI uses an EXPAND-IT attachment capable shaft, allowing you to connect various tools like edgers or blowers to the same power source. This system saves space and money if you plan to expand your tool collection later. The WORX uses a fixed shaft design integrated into the 3-in-1 kit. While the WORX battery is compatible with other 20V and 40V tools, the trimmer itself cannot be converted into other attachments. The RYOBI’s modular shaft offers greater long-term flexibility for different yard maintenance tasks. You can swap the trimmer head for other EXPAND-IT tools easily.
Weight and Maneuverability
Weight affects how fatiguing a tool is during extended use. The RYOBI trimmer weighs 11 pounds, making it significantly lighter than the WORX kit at 17.7 pounds. The WORX kit includes the trimmer, hedge trimmer, and blower attachments, which adds substantial mass. A lighter tool is easier to hold overhead or maneuver around obstacles. The RYOBI’s 11-pound weight is manageable for most users. The WORX 17.7-pound weight may cause arm fatigue during longer sessions. If you prefer a lighter tool for quick trimming jobs, the RYOBI is the more comfortable choice.
Which string trimmer fits your needs
Users wanting maximum cutting width and power
The RYOBI 40V trimmer offers a 15-inch cutting swath, which is wider than the WORX 12-inch model. It operates at 40 volts, providing more torque for thick weeds. The shaft is attachment-capable, allowing you to add other tools later. This setup replaces gas trimmers effectively while keeping maintenance low.
Buyers needing a trimmer, edger, and blower
The WORX WG931 is a 3-in-1 kit that includes a 12-inch trimmer, a wheeled edger, and a 360 CFM blower. It uses command feed for line extension. The 22-inch hedge trimmer attachment adds versatility. This bundle saves space by combining three tools into one system, all powered by the same 20V battery.
Those prioritizing lightweight maneuverability
The RYOBI model weighs 11 pounds, significantly lighter than the 17.7-pound WORX kit. Its length is 40 inches, compared to the WORX 36.3 inches. The narrower 13-inch width makes it easier to handle in tight spots. If you prefer a dedicated, lighter tool over a heavy multi-tool bundle, this spec profile suits you.
