Quick verdict
The Greenworks 40V is the best all-around curved shaft trimmer for most homeowners - more power than standard 20V models, a quality brushless motor, and a battery platform worth investing in. Budget buyers should look at the BLACK+DECKER LSTE525, which earns its price with two included batteries and the hassle-free AFS line system. Gas users with larger lots: the Husqvarna 128CD is the one to beat.
Greenworks 40V Curved Shaft Trimmer
Greenworks punches well above its price class with the 40V curved shaft trimmer. The brushless motor delivers noticeably more power and longer life than brushed alternatives, and the 40V battery platform is one of the most versatile in the battery outdoor tool space. If you're building out a battery-powered yard setup, Greenworks is a compelling ecosystem to start with.
Curved shaft string trimmers are lighter, cheaper, and perfect for small-to-medium yards. Here are five worth buying in 2026 - from battery-powered to gas.
If your yard is under a quarter acre and you’re not battling thick brush, a curved shaft weed eater is almost certainly the smarter buy. They’re lighter than straight-shaft models, easier to maneuver around garden beds and fence lines, and – importantly – less expensive both upfront and in maintenance costs.
The trade-off is reach and power. Curved shafts are shorter, which means taller users sometimes have to stoop slightly. They also don’t typically accept the range of attachments that straight-shaft commercial trimmers do. But for a typical suburban yard? They’re genuinely excellent.
Here are the five best curved shaft string trimmers you can buy right now.

The picks, reviewed
Greenworks 40V Curved Shaft Trimmer
Greenworks punches well above its price class with the 40V curved shaft trimmer. The brushless motor delivers noticeably more power and longer life than brushed alternatives, and the 40V battery platform is one of the most versatile in the battery outdoor tool space. If you're building out a battery-powered yard setup, Greenworks is a compelling ecosystem to start with.
Reasons to buy
- Brushless motor - more efficient and longer-lasting
- 40V platform compatible with other Greenworks tools
- Lightweight design reduces fatigue on longer sessions
- Variable speed trigger gives fine control
Reasons to avoid
- Battery and charger often sold separately
- 40V batteries cost more than 18V alternatives
- Line diameter limited to 0.065"
BLACK+DECKER LSTE525 Curved Shaft
BLACK+DECKER's LSTE525 is the go-to recommendation for anyone who wants a no-fuss, affordable trimmer that just works. The AFS (Automatic Feed Spool) system advances line automatically without bump-feeding - one less thing to think about during a hot afternoon. It includes two batteries, which is a genuine differentiator at this price.
Reasons to buy
- Comes with two 20V MAX batteries - double the runtime
- AFS automatic line feed - no manual bumping
- Lightweight at under 5 lbs
- Easy assembly and comfortable grip
Reasons to avoid
- 20V battery limits power on thick grass
- Line spool is proprietary AFS format
- Not ideal for large yards
Worx WG163 GT 3.0 Curved Shaft
The Worx GT 3.0 is the clever option on this list. A simple pivot of the head converts it from a string trimmer to a wheeled edge-roller - no tool needed, no attachment swapping. For yards with long driveway edges or defined garden borders, that dual function is genuinely useful and saves buying a separate edger.
Reasons to buy
- Converts to wheeled edger in seconds
- Command Feed spool control - advance line on demand
- 20V battery compatible with Worx PowerShare system
- Telescoping shaft fits multiple user heights
Reasons to avoid
- Wheeled edger mode adds weight compared to trim-only models
- 20V power tier - struggles with very dense grass
- Worx battery ecosystem smaller than BLACK+DECKER or Ryobi
Husqvarna 128CD Curved Shaft
For users who want gas power with the maneuverability of a curved shaft, the Husqvarna 128CD is the answer. Its 28cc engine handles overgrown grass and light brush that battery trimmers struggle with, and the Smart Start system makes cold starts genuinely less frustrating. This is the pick for larger yards or anyone tired of electric power limits.
Reasons to buy
- 28cc gas engine - handles thick and overgrown vegetation
- Smart Start technology reduces pull-cord resistance
- Detachable shaft for easy transport and storage
- Professional-grade build quality
Reasons to avoid
- Heavier than battery alternatives
- Requires gas/oil mixing and seasonal maintenance
- Higher upfront cost
Ryobi ONE+ Curved Shaft String Trimmer
If you already own Ryobi ONE+ 18V tools, this trimmer is an almost automatic buy. The shared battery platform means your existing batteries work here - no new charger, no new ecosystem. Standalone, it's competitive with BLACK+DECKER's entry-level offering, but the real value is battery flexibility across Ryobi's broad tool lineup.
Reasons to buy
- ONE+ 18V battery works with 280+ Ryobi tools
- Lightweight and well-balanced
- Bump-feed line advancement
- Adjustable handle for comfort
Reasons to avoid
- 18V is the lowest power tier on this list
- Struggles with tall, dense grass
- Battery sold separately in many listings
What to look for
Yard size determines power needs
For yards under 5,000 sq ft with maintained grass, an 18V or 20V battery trimmer handles everything comfortably. Quarter-acre and above - especially with any overgrown patches - consider stepping up to 40V battery or gas.
Battery ecosystem compatibility
If you already own cordless tools, buy into the same battery platform. BLACK+DECKER 20V MAX, Ryobi ONE+ 18V, and Greenworks 40V are all broad ecosystems. Cross-brand batteries are not compatible.
Line feed system
Bump-feed requires you to tap the head on the ground to advance line - it's manual but you control exactly when it feeds. Auto-feed advances line automatically as it wears. Auto-feed systems like BLACK+DECKER's AFS use proprietary spool cartridges that cost more over time. Standard bump-feed trimmers use universal.065" line you can buy in bulk.
Weight and balance
Curved shaft trimmers average 5-7 lbs. If you have wrist or shoulder issues, prioritize the lightest option (Greenworks or BLACK+DECKER) and consider a shoulder harness for longer sessions.
Our verdict
The Greenworks 40V is the best all-around curved shaft trimmer for most homeowners - more power than standard 20V models, a quality brushless motor, and a battery platform worth investing in. Budget buyers should look at the BLACK+DECKER LSTE525, which earns its price with two included batteries and the hassle-free AFS line system. Gas users with larger lots: the Husqvarna 128CD is the one to beat.
FAQs
Curved shaft trimmers are shorter, lighter, and better balanced for average-height users - ideal for small-to-medium residential yards. Straight shaft models offer more reach for taller users and professionals, handle heavier brush, and accept more attachments. For standard lawn edging and trim work, curved shaft is typically the more comfortable daily choice.
Yes - curved shaft trimmers handle standard edging along walkways and driveways well. They're particularly easy to maneuver in tight corners and around garden beds. However, for long, straight edge lines where precision is critical, a dedicated edger or a straight-shaft trimmer with an edging guard will give cleaner results.
Runtime varies by battery capacity and cutting conditions. A 40V 2.0Ah battery typically delivers 30-45 minutes of trimming on light-to-medium grass. Thick, wet grass will drain it faster. Greenworks and Ryobi both offer larger 4.0Ah batteries as upgrades if you have a larger yard or frequently tackle overgrown areas.
