Worx Weed Wacker Guide: Choosing the Right Cordless Trimmer

Choosing the worx weed wacker that fits your property requires balancing cutting swath, power configuration, line feeding, and multi-function versatility. Property owners must choose between lightweight standalone grass trimmers, combo packages with sweepers, dual-line cutting heads, and convertible edgers with rolling guide wheels. Motor power and battery voltage determine whether a tool is meant for light border detailing or clearing tough overgrown patches across residential lawns.

The Worx outdoor power equipment range organizes its string trimmer lineup around the modular PowerShare battery architecture, separating cordless tools into 20V single-battery and 40V dual-battery platforms. In addition to complete power tool kits, maintaining cutting performance depends on choosing the right pre-wound line cartridges. When performing a worx string trimmer comparison, shoppers must examine line delivery mechanisms, such as push-button Command Feed versus continuous automatic feeding, as well as dedicated replacement spool options. Homeowners comparing battery platforms across our site, such as our dewalt cordless weed coverage, will appreciate the convenience of cross-tool battery compatibility.

Worx String Trimmer Lineup at a Glance

The Models in Detail

WORX 20V 12″ Cordless String Trimmer

Best for: Yards with slopes and tight grass corridors

Pros

• 3-in-1 trimmer edger and mower
• One foot longer adjustable shaft
• Includes 3 pre-wound spools

Cons

• Five-hour battery recharge time
• 12-inch cut path limits heavy brush clearing

Best for: Suburban yards needing crisp border edging

Pros

• Rubberized edging guide wheels
• 90-degree tilting cutting head
• Ultra-lightweight 5.5-pound frame

Cons

• Slow 0.4 Ah charger included
• Single 12-inch cutting line

Best for: Homeowners needing a trimmer and blower combo

Pros

• Includes 360 CFM turbine blower
• Push-button Command Feed line
• Pivoting head converts to edger

Cons

• Heavier combined kit weight
• Single-line 12-inch cutting width

The WORX 20V 12″ Cordless String Trimmer (WG928 kit) pairs a 12-inch cordless grass trimmer and edger with a high-velocity 360 CFM turbine leaf blower. According to the listing specifications, the string trimmer features a pivoting head that transforms the tool from trimming grass around garden beds into an edger for sidewalks and driveways. Line advancement is controlled through the Command Feed line system, which supplies fresh trimmer line at the push of a button on the handle without requiring head-bumping.

The kit runs on the Worx PowerShare platform and includes two 20V 2.0Ah lithium-ion batteries and a charger. The companion leaf blower generates up to 360 CFM and air speeds of 75 miles per hour with speed control, enabling rapid cleanup of clippings, leaves, and debris from driveways and patios. With a total combined weight of 10.4 pounds, both tools are built for easy handling during routine yard maintenance.

This combo kit is designed for homeowners wanting an all-in-one trimming and post-mowing cleanup solution in a single box. However, because it centers on a 12-inch single-line cut path, users needing heavy-duty weed clearing through dense brush across larger areas will find more cutting power in the brand’s dedicated 40V models.

Worx Cordless String Trimmer

Best for: Property owners tackling dense overgrowth

Pros

• 40V dual-battery cutting power
• 13-inch dual-exit cutting head
• Continuous automatic line feed

Cons

• Lacks wheeled edging guides
• Requires two batteries to run

The Worx Cordless String Trimmer (WG183) steps up cutting performance with a 40V power plant driven by two 20V PowerShare batteries. The listing highlights a 13-inch cutting swath paired with a motor running at 7000 rpm. Rather than a single cutting strand, the worx wg183 incorporates a dual-exit cutting head that deploys two lines simultaneously, significantly improving cutting efficiency through thick grass and tough weed patches.

Operating line management is hands-free thanks to an automatic-feed spool system that advances trimmer line continuously without manual tapping. The tool features an ultra-lightweight, streamlined frame weighing just 6.4 pounds, complete with an adjustable auxiliary handle for custom balance. The package includes the grass trimmer, a pre-wound WA0007 spool, two 20V 2.0Ah batteries (WA3575), and a 2.0A dual-charger (WA3770) that recharges both batteries at the same time.

When evaluating which worx weed wacker to buy, the WG183 is the top recommendation for users who demand extra torque, dual-line cutting width, and rapid progress through thicker overgrowth. It cedes ground to smaller 20V models for operators who specifically want integrated wheeled sidewalk edging guides or convertible mini-mower functions.

Eventronic 15

Best for: Trimmer owners wanting bulk replacement spools

Pros

• 12 pre-wound spools and 3 caps
• High-strength wear-resistant nylon
• Wide Worx model compatibility

Cons

• Standard round line design
• Not compatible with dual-exit WG183

Keeping your string trimmer operating smoothly requires ready replacement line, and the Eventronic 15 pack delivers a bulk consumable solution engineered specifically for Worx weed eaters. The listing states that this bundle provides 12 replacement line spools and 3 replacement spool caps, engineered to match the WA0010 factory standard. Compatibility spans numerous Worx string trimmer models, including the WG122, WG150, WG154, WG160, WG163, WG170, and WG180 series.

Each spool is pre-wound with high-strength nylon engineered to prevent breakage during trimming and deliver 35% greater wear resistance during heavy-duty lawn care. The listing notes that the line maintains low cutting resistance at high rotational speeds, reducing motor strain and boosting cutting efficiency by 40%. The cartridges drop directly into the cutting head without requiring manual winding, allowing automatic line feed systems to work seamlessly.

This 15-pack suits homeowners and landscapers who trim frequently and want a ready stock of pre-wound spools to eliminate work stops. Because it features standard pre-wound nylon line, users tackling abrasive surfaces along stone retaining walls or chain-link fences may opt for specialized twisted line profiles like Oregon Gatorline instead.

Oregon 4-Pack Worx WA0004 Replacement Spool

Best for: Clean cutting through thick lawn weeds

Pros

• Square-twist line reduces drag
• Sharp edges slice dense grass
• Simple snap-in installation

Cons

• Only four spools per pack
• Not listed for WG183 trimmers

The Oregon 4-Pack Worx WA0004 Replacement Spool provides a heavy-duty line upgrade engineered to replace the factory Worx WA0004 spool. The listing confirms direct compatibility with extensive Worx trimmer models, including the WG122, WG150 through WG157, WG160, WG163, WG165 through WG167, WG170, WG175, and WG180 series. Swapping spools requires three steps: remove the cap, snap in the spool, and resume trimming.

Each spool in the pack is pre-wound with 0.065-inch Oregon Gatorline square-twist weed wacker string. The listing explains that this square-twist geometry provides sharp cutting edges to slice through thick weeds and dense turf while reducing vibration, operating noise, and motor drag. The four-spool package weighs 1.92 ounces, offering convenient storage. Shoppers researching spool dimensions and line types can also consult our guide on worx weedeater string options for further technical specifications.

This worx weed eater replacement spool set is tailored for homeowners who want cleaner vegetative slicing and improved motor efficiency on their worx cordless trimmer edger. It yields to larger multi-packs when the primary buying priority is raw quantity and maximum spool count for simple grass trimming.

WORX 20V 12″ 2-in-1 Cordless String

The WORX 20V 12″ 2-in-1 Cordless String trimmer and electric lawn edger (model WG163) provides a dedicated yard maintenance platform for typical residential properties. According to listing specifications, this 12-inch trimmer operates with a 7600 rpm no-load speed and weighs just 5.5 pounds. The tool converts from a horizontal grass trimmer to an in-line lawn edger in seconds, consolidating two essential yard care tools into a single unit.

Precision edging is enhanced by built-in rubberized wheels that support the tool along driveways and sidewalks for clean, straight cut lines. The trimmer head tilts 90 degrees to handle uneven terrain and sloped patches, while an adjustable spacer guard protects plants and garden ornaments. The worx wg163 utilizes the push-button Command Feed spool system for instant line deployment. The listing includes two 20V 2.0Ah maxLithium batteries, a 0.4 Ah charger, a pre-wound spool, support wheels, and a safety guard.

This worx 20v string trimmer is the go-to recommendation for small-to-medium suburban yards where neat edge detailing along walkways is the primary task. However, homeowners who want extended shaft length for improved posture or an integrated mini-mower setting will find those additional capabilities in the WG170 model.

WORX 20V 12″ 3-in-1 Cordless String

The WORX 20V 12″ 3-in-1 Cordless String trimmer, lawn edger, and mini mower (model WG170, the GT Revolution) provides maximum functional versatility. Running at 7600 rpm with a 12-inch cutting diameter, the tool transforms between a precision string trimmer, an in-line wheeled edger, and a rolling mini lawn mower. The mini-mower setup locks the head horizontally over the support wheels, allowing users to mow tight grassy strips and ditch slopes where regular push mowers cannot fit.

The listing notes that the worx wg170 features a shaft that is an entire foot longer than previous Worx trimmers, paired with 7 handle adjustments and 6 rotating head settings to optimize ergonomics for users of any height. The tool incorporates the push-button Command Feed system to advance line without stopping. Weighing 5.5 pounds, the package includes two 20V 2.0Ah max lithium batteries, a charger with a 5-hour charging time, 3 trimmer spools, an on-tool spool holder, support wheels, and protective guards.

The WG170 represents the ultimate convertible string trimmer for intricate yards, awkward slopes, and properties requiring flexible cutting angles. However, property owners with large open tracts of dense brush or overgrowth will prefer the wider 13-inch dual-line cutting head of the worx 40v string trimmer.

Matching a Model to Your Setup

• Suburban yards needing balanced trimming and wheeled sidewalk edging match the WORX 20V 12″ 2-in-1 Cordless String (WG163) for lightweight handling and rubberized guide wheels.
• Properties with tight slopes, ditch banks, and taller operators match the WORX 20V 12″ 3-in-1 Cordless String (WG170) for its extended shaft, multi-angle head adjustments, and mini-mower conversion.
• Larger properties with thick weed patches and tough overgrowth match the Worx Cordless String Trimmer (WG183) for 40V dual-battery power, a 13-inch cut swath, and dual-exit cutting lines.
• Homeowners wanting complete post-mow maintenance in a single purchase match the WORX 20V 12″ Cordless String Trimmer (WG928) for its bundled 12-inch trimmer and 360 CFM turbine leaf blower.
• Heavy-duty edge trimming along chain link and masonry matches the Oregon 4-Pack Worx WA0004 Replacement Spool for square-twisted Gatorline that reduces drag and slices cleanly.
• Multi-season spool replenishment for high-frequency trimming matches the Eventronic 15 for its 12 pre-wound spools and 3 replacement caps.

Before You Buy

The product listings do not specify exact battery runtime in minutes for these cordless trimmers. While the WG170 description mentions that two 2.0Ah batteries provide sufficient capacity for a typical quarter-acre lawn, runtime varies based on grass height, weed density, and operational habits. Furthermore, the 20V trimmer kits include 0.4 Ah chargers with listing-specified charging times up to 5 hours, meaning homeowners with expansive yards should consider whether they require extra batteries or faster charging hardware.

Trimmer line compatibility also requires careful attention before purchasing spare cartridges. While third-party replacement packs like the Eventronic 15 and Oregon 4-Pack explicitly fit single-line models including the WG163 and WG170, the listings do not specify compatibility with the dual-exit WG183 trimmer head, which requires the WA0007 spool standard. Shoppers should always verify their trimmer model number and spool part number before purchasing bulk replacement lines.

FAQ

How does the Worx Command Feed line system work?

The Command Feed system uses an electronic push-button switch mounted directly on the trimmer handle. Pressing the button feeds out a measured length of cutting line instantly while operating, eliminating the need to tap or bump the cutting head on the ground.

Can 20V Worx batteries be used in 40V trimmers?

Yes, the Worx PowerShare platform is modular. The 40V WG183 string trimmer operates by using two standard 20V PowerShare batteries simultaneously, which can also be detached and used individually in any 20V Worx power tool or lifestyle product.

What is the difference between the Worx WG163 and WG170?

Both models share a 12-inch cutting width, 7600 rpm motor speed, and 5.5-pound weight, but the WG170 adds a third mini-mower configuration, features a shaft that is one foot longer, and offers 7 handle adjustments and 6 rotating head settings compared to the WG163.

What line diameter do Worx cordless string trimmers use?

According to the listing specifications for the WG163, standard Worx 20V string trimmers use 0.065-inch diameter line. Replacement spools like the Oregon Gatorline pack also utilize pre-wound 0.065-inch line to ensure smooth feeding through factory heads.

Are all Worx trimmer spools interchangeable?

No, replacement spools are not universal across the entire Worx catalog. While standard single-line trimmers like the WG163 and WG170 share compatibility with WA0004 and WA0010 spools, dual-line models like the WG183 require the WA0007 spool format.
