DeWalt DCST972X1 FlexVolt 60V Max Brushless String Trimmer
Best OverallPros
- Brushless motor delivers high torque
- FlexVolt battery works with 60V and 20V tools
- Durable metal gearbox
Cons
- Heavier than 20V models
- Battery and charger sold separately
The DCST972X1 is the flagship DeWalt grass trimmer, featuring a brushless motor that provides consistent power even through thick weeds. Owner reviews on Amazon and Home Depot consistently note its ability to handle overgrown lawns without bogging down, and the 15-inch cutting width reduces trimming time significantly.
The FlexVolt battery automatically switches voltage when used with other DeWalt tools, making this a smart investment for those already in the ecosystem. However, the 11.2-pound weight can be tiring during extended use, and the bump feed mechanism requires a firm tap on the ground.
DeWalt DCST925X1 20V Max Brushless String Trimmer
Best for Medium YardsPros
- Lighter than FlexVolt models
- Brushless motor for efficiency
- Compatible with 20V battery range
Cons
- 13-inch width slower for large lawns
- Plastic gearbox housing
The DCST925X1 strikes a balance between power and weight, making it ideal for medium-sized gardens. Owner feedback highlights its ease of use and reliable bump feed, though some note the plastic gearbox feels less durable than the metal unit on the 60V model.
Battery life with a standard 5Ah 20V pack is adequate for a typical suburban yard, but heavy weeds may drain it faster. The brushless motor provides good runtime and less vibration compared to brushed alternatives.
DeWalt DCST920P1 20V Max String Trimmer
Best BudgetPros
- Lowest price in DeWalt lineup
- Lightweight and easy to maneuver
- Battery and charger included
Cons
- Brushed motor less efficient
- 12-inch width limits coverage
The DCST920P1 is the entry-level DeWalt trimmer, using a brushed motor to keep costs down. It is best for small gardens or light trimming tasks, with owner reviews praising its affordability and ease of use for basic lawn edging.
Battery life is shorter than brushless models, and the 12-inch cutting width means more passes for larger areas. The bump feed works reliably, but the plastic construction feels less robust than higher-end models.
DeWalt DCFT100 12V Max Cordless Grass Trimmer
Best for Light EdgingPros
- Extremely lightweight
- Compact for tight spaces
- Shares 12V battery with other DeWalt tools
Cons
- Limited power for thick grass
- Manual line feed is inconvenient
The DCFT100 is a compact trimmer designed for edging along sidewalks and flower beds. Its 8-inch cutting width and low weight make it easy to handle, but owner reviews indicate it struggles with anything beyond light grass.
Battery life is short due to the small 12V pack, and the manual line feed requires stopping to advance the string. It is best used as a secondary tool for detail work rather than primary trimming.
DeWalt DCST970X1 FlexVolt 60V Max String Trimmer
Best VersatilityPros
- Variable speed trigger for control
- Dual line bump head
- High power for tough weeds
Cons
- No quick-load line feature
- Heavy for prolonged use
The DCST970X1 offers similar power to the DCST972 but with a variable speed trigger that gives more control for delicate edging. Owner reviews appreciate the dual line bump head for faster cutting, though some find loading new line tedious.
Battery performance is strong with the FlexVolt system, providing enough runtime for large gardens. The weight is comparable to other 60V models, making it less suitable for users with mobility concerns.
Who is a DeWalt Grass Trimmer For?
DeWalt grass trimmers are designed for users who prioritize durability and battery ecosystem compatibility. The brand is best suited for homeowners with existing DeWalt power tools, as the 20V and 60V FlexVolt batteries work across a wide range of equipment. Models like the DCST972X1 are ideal for large gardens with thick grass, while the DCST920P1 serves smaller yards on a budget.
Performance and Build Quality
DeWalt trimmers generally use brushless motors in their higher-end models, which improve efficiency and runtime compared to brushed alternatives. The FlexVolt 60V models deliver torque comparable to gas trimmers, making them effective against overgrown vegetation. Build quality varies by price point, with metal gearboxes on 60V models and plastic housings on 20V units. Owner reviews on Amazon and Home Depot consistently report good reliability, though some note that the bump feed mechanism can jam if not used correctly.
Battery and Ecosystem Considerations
DeWalt's 20V Max and FlexVolt systems offer broad compatibility. The FlexVolt batteries automatically adjust voltage when used with 20V tools, providing flexibility for users with mixed tool collections. Battery life depends on the model and capacity, with 5Ah packs lasting 30-45 minutes under heavy use. The 12V DCFT100 uses a separate battery system, so it is best for those already in the 12V ecosystem.
Alternatives to DeWalt Grass Trimmers
For users not invested in DeWalt's battery system, brands like Makita and Stihl offer competitive options. The Makita XRU15Z provides similar power with a 36V system, while Stihl's FSA 60 R is lighter and easier to handle. Ryobi offers more affordable 40V models with a wider range of attachments. Each alternative has its own ecosystem, so consider your existing tools before switching.
