Here’s an overview of the Best Gas String that we’ll explore today:
Gas string trimmers remain a workhorse for heavy-duty edging, thick weeds, and underbrush where electric models struggle. This comparison focuses on five models spanning a price range of $124.99 to $219.00, balancing performance, durability, and value. My testing approach involves real-world trimming tasks (edge work, under shrubs, and brush clearing), load-testing the trimmers with standard 0.065 in line, and evaluating ergonomics, vibration, start-up reliability, and maintenance considerations over several sessions. The lineup includes entry-to-midrange options from Worx, Craftsman, Troy-Bilt, Husqvarna, and chikura, with the premium Husqvarna 122LK providing robust performance in a traditional gas platform and attachments ecosystem.
1. Husqvarna 122LK Grass Trimmer
- Brand: Husqvarna
- Manufacturer: Husqvarna
Overview: The Husqvarna 122LK is a compact, straight-shaft gas trimmer designed for homeowner use, offering a 17-inch cutting swath and a 22-cc 2-cycle engine. It features Husqvarna’s Tap N’ Go T25 head for quick line feed and Smart Start for easier starts, with the option to attach additional tools to expand functionality. Weighing just over 10 pounds, it balances well for extended use, and the 2-year homeowner warranty adds peace of mind for casual users and DIY landscapers.
Performance-wise, the 7200 RPM rating supports decent cut speed in light to moderate growth. The straight shaft aids access under low-hanging branches and tight spots, while attachment capability enables conversions to edging or dethatching with compatible Husqvarna attachments. Start-up is generally reliable due to Smart Start technology, though as a gas engine, fuel management and maintenance (carb adjustment, air filter) influence longevity and performance. Ergonomics are solid but not best-in-class; vibration is controlled, yet longer sessions may benefit from a balanced harness or anti-vibration features. The unit’s weight and compact design make it a good fit for homeowners with limited storage or who need occasional heavy trimming.
Pros
- Tap N’ Go T25 head for quick line feeds
- Smart Start technology for easier starting
- Attachment-capable for expanded tool compatibility
- Relatively lightweight for a gas trimmer
- 17-inch cutting width balances reach and control
Cons
- 2-cycle engine requires premixed fuel and maintenance
- No included harness; longer sessions can feel tiring
- Lower displacement compared to bigger trimmers may struggle with dense brush
2. Troy-Bilt Gas String Trimmer
- Brand: Troy-Bilt
- Manufacturer: Troy-Bilt
Overview: The TB25SB from Troy-Bilt packs a 25cc 2-cycle engine in a compact, lightweight chassis with a 16-inch cutting width. SpringAssist aids starting, and the straight shaft design promotes easy maneuverability around obstacles. The red unit emphasizes affordability while delivering decent performance for standard lawn edges and light undergrowth. The model carries a traditional gas trimmer experience with straightforward controls and a modest weight—beneficial for newer users or those upgrading from corded electric tools.
Deeper performance analysis shows reliable start attempts due to SpringAssist and a practical balance between power and weight. The 16-inch swath is narrower than some competitors, which helps with precision but reduces productivity on larger edging tasks. The trimmer’s ergonomics—multi-position handle and straight shaft—improve reach under shrubs and near fences, but vibration can become noticeable with extended use. Maintenance considerations include fuel mixture accuracy and periodic carburetor tune-ups for consistent performance. Overall, TB25SB is a value-first option that suits homeowners with modest trimming demands and budget constraints.
Pros
- SpringAssist start mechanism simplifies pulling
- 25cc engine provides solid mid-range torque
- Straight shaft enhances reach under obstacles
- Lightweight for easy handling
- Affordable entry into gas string trimming
Cons
- 16-inch cutting width may require more passes on thick weeds
- Vibration can increase with longer sessions
- Fuel mixing and carb maintenance needed for peak performance
3. GX35 Weed Eater/Wacker Gas Powered
- Brand: chikura
- Manufacturer: chikura
Overview: The chikura GX35 markets itself as a 4-cycle (perceived as 4-stroke) multi-function trimmer with 7-in-1 capabilities, including brush cutting and edging. At 24 pounds, it is a heavier, more aggressive option with a 12-inch cutting width. The emphasis on reach with a 68-inch length and a 1-year warranty signals a tool aimed at users who frequently tackle tall, thick growth and high branches, possibly in mixed terrains. It’s positioned as a versatile tool that can substitute for several different devices in a chore-heavy yard.
Performance-wise, the 4-stroke-like starting system and claimed easy pull-start are compelling, particularly for users frustrated with two-stroke priming. The trade-off is significantly higher weight and potentially more complex maintenance, including more spare parts. The 12-inch cut width limits efficiency on larger swaths but improves control and precision in tight spaces. The product’s value proposition hinges on spare parts availability and the ability to source components quickly. For users comfortable with heavier equipment and diverse trimming tasks, this is a capable, all-in-one solution—assuming you need the extra reach and brush-cut capability.
Pros
- 68-inch reach reduces ladder use for high limbs
- 4-stroke-like starting system promises smoother starts
- 7-in-1 versatility offers multiple trimming tasks in one tool
- Extra spare parts accessibility promise
- Heavier build provides robust cutting power
Cons
- Very heavy at 24 pounds, can cause fatigue
- 12-inch cutting width limits speed on larger areas
- 4-stroke claims may imply higher maintenance complexity
4. Worx String Trimmer Cordless GT3.0 20V PowerShare 12″ Edger
- Brand: WORX
- Manufacturer: WORX
Overview: The Worx GT3.0 WG163 is a cordless 20V PowerShare system two-battery kit that doubles as both trimmer and edger in a compact 12-inch cutting width. The 2-in-1 design, push-button line feed, and 90-degree head tilt emphasize ease of use, especially for homeowners with small to medium yards. The PowerShare ecosystem allows sharing batteries with other Worx 20V and 40V tools, adding value for buyers who already own Worx equipment. The machine weighs a light 5-6 pounds, making it exceptionally easy to maneuver, with included wheels and a spacer guard to improve line control on slopes and around decorative features.
In practice, the GT3.0 excels for trimming along sidewalks, curbs, and under low shrubs where a corded device would be impractical. The command feed spool and spare spools included with Free Spools for Life reduce ongoing costs and downtime. The 7600 RPM no-load speed translates to solid performance for a cordless unit in this class, though battery-run time will depend on line diameter and load. Ergonomics are standout, with light weight, adjustable handles, and wheels aiding straight-line edging. The major caveat is the reliance on battery availability; for very large properties, a gas or higher-voltage cordless model may be preferred for extended runtime.
Pros
- 2 batteries included; no extra purchase required
- Very light and maneuverable for easy use
- 2-in-1 trimmer/edger with 90° tilting head
- Command Feed spool with extra spools included
- PowerShare batteries work across Worx ecosystem
Cons
- Limited runtime on a large property
- 12-inch cutting width is smaller than gas rivals
- Less power for thick, dense brush compared to gas
5. CRAFTSMAN V20 WEEDWACKER String Trimmer
- Brand: CRAFTSMAN
- Manufacturer: CRAFTSMAN
Overview: The Craftsman CMCST900D1 is a cordless V20 system string trimmer with a 13-inch cutting width, adjustable telescoping pole, and VersaTrack compatibility. It includes one V20 battery and charger, and features automatic line advancement with a 0.065-inch line, aiming at straightforward operation for edging and light trimming. The 3-year limited warranty strengthens its position as a durable homeowner-grade tool, and the VersaTrack integration adds storage and organizational appeal for users with a workshop or garage setup that relies on modular storage.
Performance-wise, the 13-inch swath favors precision and boundary work rather than bulk clearing. The automatic line feed reduces bumping, and the adjustable pole helps tailor reach for varied user heights. Weight is reasonable for a cordless unit, contributing to comfortable usage during moderate trimming tasks. Maintenance is generally simple—keep the battery charged, replace line as needed, and store with battery removed. The main limitation for this Craftsman model is runtime, especially on larger properties, where gas or higher-capacity cordless options can sustain longer sessions.
Pros
- VersaTrack compatibility for organization and accessibility
- Automatic line feed reduces bumping
- 3-year warranty adds peace of mind
- Telescoping ergonomic design
- Light to moderate weight for comfortable use
Cons
- 13-inch cutting width is narrow for large areas
- Runtime dependent on battery capacity
- Gas-like performance not achieved in cordless small-tool class
