Choosing the right string trimmer for your yard can feel overwhelming. Two models that consistently rise to the top of the conversation are the Toro 51621 vs Worx WG509. This comparison will help you see which one fits your specific needs and property.
Both are well-regarded electric trimmers, but they take different approaches to lawn care. One is a corded workhorse, and the other offers cord-free convenience. Let’s look at the details so you can make a confident choice without any confusion.
Toro 51621 vs Worx WG509
Before we get into the weeds, here’s a quick overview of what each model brings to the table. This high-level look shows their fundamental differences.
Toro 51621 14-inch Electric String Trimmer:
* Power Source: Corded Electric (requires an outlet and extension cord).
* Cutting Swath: 14 inches.
* Weight: Approximately 7.3 lbs.
* Key Feature: “Dual Line” Automatic Feed Spool (AFS) system.
Worx WG509 20V Power Share Cordless String Trimmer:
* Power Source: Cordless, Battery-powered (uses 20V battery, often sold as tool-only).
* Cutting Swath: 12 inches.
* Weight: About 5.3 lbs (without battery).
* Key Feature: Part of the WORX Power Share ecosystem, uses Command Feed spool system.
Power and Performance: Corded Muscle vs Cordless Freedom
The biggest decision point here is power source. It dictates how you’ll use the tool and what your yard work routine will look like.
The Toro 51621 is a corded electric model. This means it provides consistent, unlimited runtime as long as you have access to an outlet. You never have to worry about the battery dying halfway through a job. The trade-off is managing a 100-foot extension cord, which can be cumbersome. You’ll need to plan your path to avoid cutting the cord and be mindful of dragging it across flower beds.
The Worx WG509 is a cordless trimmer that runs on a 20V lithium-ion battery. This offers complete freedom of movement, which is a huge advantage for yards with many obstacles or larger areas. Runtime depends on your battery’s amp-hour (Ah) rating. A standard 2.0Ah battery might last 20-30 minutes of continuous use, while a 4.0Ah or 5.0Ah battery will last much longer. If you already own other WORX Power Share tools, you can share batteries, which is a major cost saver.
Design and Usability: Handling and Comfort
How a trimmer feels in your hands is crucial, especially for longer sessions. Both models have thoughtful designs, but they cater to slightly different preferences.
The Toro 51621 has a more traditional straight-shaft design. This is excellent for reaching under bushes and fences without bending over. At over 7 pounds, it’s the heavier of the two, but the weight is balanced. The rear handle is adjustable, which helps you find a comfortable operating position.
The Worx WG509 features a curved shaft and is notably lighter, especially before you add the battery. This makes it very easy to maneuver and causes less user fatigue. Its design is often preferred for general trimming and edging around walkways and flower beds. The lighter feel can be a blessing for anyone with shoulder or back concerns.
Cutting Features and Edging Capability
Both trimmers handle standard grass and weed trimming well, but their feeding systems and edging functions differ.
Toro 51621 Cutting System:
* It uses Toro’s patented Dual Line AFS. This system automatically advances two lines when you tap the head on the ground.
* It’s a reliable, bump-free system that many users appreciate for its simplicity.
* The 14-inch cutting width lets you cover more area with each pass.
* To edge, you simply rotate the head 90 degrees—no tools required. It’s a straightforward, effective system.
Worx WG509 Cutting System:
* It uses the WORX Command Feed system. You press a button on the handle to advance fresh line, which gives you precise control and reduces line waste.
* The cutting swath is a bit smaller at 12 inches.
* For edging, the entire motor head rotates with the push of a button and a twist of the shaft. This is a very slick, tool-free feature that works reliably.
Maintenance and Durability Considerations
Long-term ownership depends on easy maintenance and solid construction. Here’s what you can expect.
Maintaining the Toro is generally simple. Reloading the AFS spool is a straightforward process, and the durable construction holds up well over time. The main wear item besides the line is the extension cord itself. Since it has no battery, there are no components that will degrade and need replacing in a few years.
The Worx requires you to monitor battery life and charge cycles. The tool itself is quite durable for a cordless model. Reloading the Command Feed spool is also user-friendly. The long-term consideration is battery lifespan; lithium-ion batteries eventually lose their capacity and will need to be replaced after several years of use.
Which Trimmer Should You Choose?
Your decision ultimately comes down to your yard’s layout and your personal priorities.
Choose the Toro 51621 if:
* Your yard is within 100 feet of an outdoor power outlet.
* You have a lot of thick, overgrown weeds that benefit from consistent power.
* You prefer a longer cutting swath and a traditional straight-shaft design.
* You don’t want to think about battery life or charging.
Choose the Worx WG509 if:
* You value cordless freedom and have a yard with many trees, gardens, or obstacles.
* You already own other WORX Power Share 20V tools (you can use the same batteries).
* You need a lightweight, easy-to-maneuver trimmer for routine upkeep.
* You appreciate the quick, button-activated edging feature.
Both are excellent tools that perform their jobs well. The “best” one is the one whose limitations you mind the least. For raw, uninterrupted power, the Toro’s cord is a small price to pay. For effortless maneuverability and modern convenience, the Worx’s battery is the clear winner.
FAQ Section
Q: Which has more power, the Toro 51621 or Worx WG509?
A: The corded Toro 51621 generally delivers more consistent, higher torque power directly from the outlet. The Worx WG509 provides ample power for most trimming tasks, but its output can dimish as the battery charge gets low.
Q: Can the Worx WG509 handle thick weeds?
A: Yes, the Worx WG509 can handle moderate thick weeds, especially with a fresh, high-quality line. For very dense or woody growth, the continuous power of the corded Toro might have a slight advantage.
Q: Is the Toro trimmer difficult to use because of the cord?
A: It requires more planning. You must manage the extension cord to avoid tangling or cutting it. For open areas, it’s fine, but it can be frustrating in very cluttered yards.
Q: How long does the Worx battery last?
A: Runtime varies greatly. With the included 2.0Ah battery, expect 20-30 minutes of actual trimming. Upgrading to a 4.0Ah or 5.0Ah battery can double or triple that time, making it suitable for larger properties.
Q: Are both trimmers easy to restring?
A: Yes, both are designed for easy reloading. The Toro uses a pre-wound spool you drop in, while the Worx spool is also simple to wind and install. Both systems are much easier than older trimmer models.
In the end, comparing the Toro 51621 vs Worx WG509 highlights a classic choice: steadfast power versus liberating mobility. Assess your yard’s specific challenges and your own preferences, and you’ll find the perfect partner for keeping your edges neat and your weeds in check.
