What customers say
Customers overwhelmingly praise the DEWALT DCST925B String Trimmer for its exceptional comfort and lightweight design. Its superior maneuverability makes yard work noticeably easier, especially for medium properties. The 20V MAX platform offers effective power for standard residential trimming and edging, benefiting from the gear drive transmission that eliminates gas maintenance hassles. Users value the variable speed trigger for precise control and battery conservation. While the tool is celebrated as a reliable, powerful cordless alternative to gas models, some feedback notes issues with the automatic line feed system, citing occasional jamming or high line consumption. Overall, comfort and cordless performance are the key strengths.
Know before you buy
No, the DCST925B is a bare tool. You will need to purchase a DEWALT 20V MAX battery and charger separately if you do not already own them.
This model is designed for grass and light weeds. While the gear drive transmission provides extra torque for dense overgrowth, it is best suited for standard residential lawn maintenance rather than thick woody brush.
This trimmer features an automatic feed system. It will automatically dispense more line as needed while you are trimming, so you do not need to bump the head against the ground.
The shaft is a fixed-length straight design. It is engineered to provide an ergonomic reach for most users, but it does not telescope.
It is designed for use with a 0.080-inch diameter trimmer line. It comes pre-wound with this size, and you should stick to this specification for optimal performance and to prevent jamming.
Yes, this model is compatible with the DEWALT attachment system, allowing you to swap the trimmer head for other compatible attachments to increase the versatility of your power head.
