Milwaukee M18 Fuel String Trimmer
Best OverallPros
- Excellent power for thick weeds
- Long runtime with High Output battery
- Durable build quality
Cons
- Heavier than some competitors
- Premium price point
The Milwaukee M18 Fuel string trimmer delivers the highest power output in its class, making it ideal for tackling overgrown grass and thick weeds. Owner reviews consistently praise its brushless motor and the ability to run on the same batteries as other Milwaukee tools. The auto-feed line system is reliable and reduces downtime.
Some users note the weight can be tiring during longer sessions, but the trade-off is unmatched cutting performance. For those already in the Milwaukee ecosystem, this is the clear top pick. It is best suited for medium to large yards with demanding trimming needs.
DeWalt DCST970 String Trimmer
Best ValuePros
- Wide cutting path for efficiency
- Good balance of power and weight
- Affordable for the performance
Cons
- Battery not included with some kits
- Bump feed can be inconsistent
The DeWalt DCST970 offers a 17-inch cutting width, making it one of the most efficient trimmers for covering ground quickly. It runs on the 60V FlexVolt battery, which provides ample power for most residential yards. Owner reviews highlight its comfortable grip and manageable weight for extended use.
Some users report the bump feed mechanism requires a firm tap to advance the line, which can be a minor annoyance. However, the overall value is strong, especially for those already using DeWalt 20V or 60V tools. It is a reliable choice for homeowners who want solid performance without the premium price.
Ryobi 40V HP String Trimmer
Best BudgetPros
- Very affordable price
- Lightweight and easy to maneuver
- Good battery life for the price
Cons
- Less power for thick weeds
- Plastic build feels less durable
The Ryobi 40V HP string trimmer is the best budget option for homeowners with smaller yards. It is lightweight and easy to handle, making it a great choice for light trimming around flower beds and fences. Owner reviews appreciate the value and the auto-feed line system that works reliably.
It struggles with very thick or overgrown grass compared to higher-end models. The plastic components may not withstand heavy use over many years. For the price, however, it delivers acceptable performance and is a smart entry point into the Ryobi 40V ecosystem.
Stihl FSA 90 String Trimmer
Best LightweightPros
- Very lightweight and comfortable
- Good build quality from Stihl
- Quiet operation
Cons
- Narrower cutting width
- Battery and charger sold separately
The Stihl FSA 90 is designed for users who prioritize comfort and ease of use. It is one of the lightest battery trimmers available, reducing fatigue during longer trimming sessions. Owner reviews note the balanced design and the reliable Stihl build quality.
The narrower 14-inch cutting width means it takes longer to cover larger areas. The battery is not included in the base price, which increases the overall cost. For those with smaller yards or who need a trimmer for detail work, the Stihl FSA 90 is an excellent choice.
Makita XRU23 String Trimmer
Best DurabilityPros
- Rugged and durable construction
- Powerful twin-battery system
- Long warranty
Cons
- Heavier than single-battery models
- Requires two batteries for full power
The Makita XRU23 uses two 18V batteries to deliver consistent power without fading. It is built to withstand tough conditions, with a metal shaft and reinforced head. Owner reviews highlight its longevity and the ability to handle heavy trimming tasks without bogging down.
The dual-battery setup adds weight, and the need for two batteries can be a barrier for new users. It is best for those who already own Makita 18V tools and need a trimmer that will last for years. The Makita XRU23 is a durable workhorse for serious gardeners.
What to check before buying a string trimmer
Power source is the first decision. Battery trimmers offer convenience and less noise, but gas models still provide more torque for heavy brush. Consider the cutting width: wider paths cover more ground but can be harder to maneuver in tight spaces. Weight matters for comfort, especially if you have a large yard. Line feed systems include bump, auto, and manual; bump is common but auto is more convenient. Check the battery ecosystem if you already own tools from a brand like DeWalt, Milwaukee, or Ryobi. Finally, look at the shaft design: straight shafts are better for reaching under bushes, while curved shafts are lighter and easier for edging.
Mistakes to avoid when buying a string trimmer
One common mistake is buying a trimmer with too narrow a cutting width for your yard size, leading to longer work times. Another is ignoring the battery voltage: a 40V or 60V system provides more power than 18V for thick grass. Do not overlook the line feed mechanism: bump feed can be frustrating if you have to stop frequently. Avoid buying a trimmer without checking the weight, as a heavy tool can cause fatigue. Finally, do not assume all trimmers fit all attachments; check compatibility if you plan to use edger or blower attachments.
