Best String Trimmers Under $300 (2026)

The EGO Power+ ST1510T leads this page as its one trimmer with a price checked in the last month. It is a 15-inch 56V string trimmer with POWERLOAD, which loads new line from a cartridge without taking the head apart, a brushless motor, and a telescoping aluminum shaft that adjusts for users from about 5 feet to over 6 feet tall. It is sold as a bare tool: the battery and charger are not included, and it is rated for up to 45 minutes of runtime on a compatible EGO 56V battery. If you do not already own EGO batteries, budget for one on top of the tool price. Setup can take 30 to 60 minutes before first use. Choose it if you own EGO 56V batteries or plan to build on that platform. If you want a complete kit in the box, the WORX 3-in-1 on this page includes two batteries and a charger.

The BLACK+DECKER 20V MAX is a 2-in-1 cordless string trimmer and edger with automatic spool feed, and its listing includes a battery and charger. The listing title also mentions a 12-inch steel deck, and its last recorded price sits well above typical 20V trimmers, so check exactly what the bundle contains before buying. At 20V it has less power than the 40V RYOBI and 60V Toro on this page, which suits edging and light trimming better than thick growth. Choose it for small yards and tidy edges if the listing matches what you need; for heavier trimming, the RYOBI or Toro on this page carry more power.

Expand-It compatibility is the RYOBI 40V's defining feature: the trimmer head accepts the full RYOBI Expand-It attachment line — edger, cultivator, hedge trimmer, and blower — converting a single tool into a multi-function outdoor platform. Buyers who already own RYOBI 40V batteries drop the effective cost of this kit immediately, since the included 4.0Ah battery is interchangeable with any RYOBI 40V tool in the lineup. Against the WORX WG170 on this page, it is heavier but adds attachment compatibility; against the EGO ST1510T, it comes as a kit with a 4.0Ah battery, while the EGO is sold as a bare tool. For RYOBI ecosystem owners the platform advantage is clear. The 13-15 inch adjustable swath handles typical residential trim lines without issue. The honest trade-off: the 40V battery and head assembly make this trimmer meaningfully heavier than 20V alternatives, and the Expand-It attachment heads are sold separately — factor in one or two attachment costs if the platform flexibility is the main reason you're buying.

A brushless motor at 60V is the Toro Flex-Force's core pitch — brushless motors run cooler, last longer, and convert more battery energy into cutting power than brushed alternatives. The 14/16-inch adjustable swath gives flexibility for tight trimming around flower beds (14-inch) and open lawn edges (16-inch). Battery and charger are included, which makes it comparable to bare-tool options from competing brands. The 60V ecosystem is the main consideration for new buyers. Toro Flex-Force batteries don't cross with EGO, Greenworks, or RYOBI — what you buy here, you commit to for future Toro tool purchases. For buyers already invested in Toro Flex-Force outdoor power tools, this is the obvious trimmer. For buyers starting from zero, the RYOBI Expand-It offers attachment platform value and broader ecosystem access at a similar price. Against the EGO ST1510T on this page, the Toro includes a battery and charger, where the EGO is sold as a bare tool.

The WORX WG170 is a 3-in-1 cordless tool: a 12-inch, 20V string trimmer that converts to a lawn edger and a mini mower for small patches of grass. It weighs 5.5 lbs, uses Command Feed to advance line, and comes with two batteries and a charger, so it works out of the box. A 12-inch swath and 20V power make it a tool for small yards and edging rather than thick growth or large properties. Choose the WORX for a complete, lightweight kit for a small yard. For more power, the 40V RYOBI or 60V Toro on this page are the step up.
