Best Greenworks Cordless String Trimmers (2026)

This is the best balance of weight, power and battery in the range. A brushless motor drives a 13 inch cutting path with 0.080 inch line, which is heavier than the 0.065 inch line on most 24V trimmers, and an auto-feed system keeps the line advancing without bumping. A 4.0Ah battery is included, which is large for the 24V platform.

It converts easily between trimmer and edger, so one tool covers the lawn edge and the pavement edge. The 24V platform is the lightest in the brand's line, so the tool is easy to carry and use for a long session, and the brushless motor holds speed better than a brushed one as the pack runs down.

The limits are the platform and the thin single line: it is not a brush cutter. For regular lawn care on a medium lot it is exactly right. Clean the head after each use, replace the line when it gets short and store the battery indoors in winter. A 4.0Ah pack on a 13 inch head is a comfortable match, so you will usually finish a medium lot with charge to spare. If you later add a blower or hedge trimmer on the same platform, the pack carries over.

The 60V trimmer is the heaviest-duty machine the brand sells, and it is built to replace a gas trimmer. A 16 inch swath, dual 0.095 inch line and a brushless motor rated up to 6,000 RPM are the figures behind the maker's claim of 26cc gas-class power.

Its best feature is the reload. The head twists open and takes new line in about ten seconds with no winding, which the maker contrasts with a bump feed head, and fast reloading is what makes a thick line usable. The line is the heaviest in the range.

The cost is weight and a modest 2.5Ah pack, so a large property needs a second battery. The 60V pack is shared with the brand's other 60V tools, such as the blower in the combo kit. Use it for ditches, fences and overgrowth, and clean the head after each session. Work at about half throttle on open grass and save the full trigger for thick patches, since the pack drains quickly at full power. It is a tool for owners who have been disappointed by lighter trimmers and want something closer to a gas machine.

This 40V model is the best value for a larger lawn. A 15 inch dual-line head with 0.085 inch line sits between the 24V and 60V models, and the TORQDRIVE system provides, according to the maker, 30 percent more torque than a standard drive. A variable speed trigger lets you slow the head around plants.

The head is a bump feed, so you tap it on the ground to advance line, which is simple and robust but wastes line on hard surfaces. The pack is a 2.0Ah battery in the kit, small for a 15 inch swath, so a spare is a sensible purchase.

The 40V line is the brand's older platform, with a wide range of batteries and tools sold over the years, so spares are easy to find. Keep the head free of wrapped grass and tap on soft ground only. The variable trigger is worth learning to use, because a head at half speed throws far less debris at window glass and plants. Treat the TORQDRIVE claim as a helpful relative figure, not an absolute power rating.

The distinctive feature is the head: it switches modes in three clicks and has seven pivot positions, which you move from trimming under decks at position 1 to edging sidewalks at position 3, clearing fence lines at position 5 and detailing flower beds at position 7. A steel edging guide is included for crisp lawn borders.

The shaft adjusts from 40 to 52 inches to fit users from about 5 feet 2 inches to 6 feet 4 inches, and the maker lists a weight of 7.8 pounds with anti-vibration technology. At that weight it is not the lightest, but the adjustability reduces back strain.

A 2.0Ah battery and charger are included. The 0.065 inch line suits lawn edges and light weeds. If edging is your main chore, the pivot and edging guide are the reason to choose this model. Set the shaft so your elbows are slightly bent and the head sits flat on the ground, then check the pivot position before you start each task. The seven positions are only useful if you actually change them, so learn which one suits each job.

This 24V kit has a telescoping aluminium shaft that suits users from 4 feet 8 inches to 6 feet 5 inches, which covers nearly every adult in a household. A brushless motor drives a 12 inch cutting path with 0.065 inch dual line, and the head converts between trimmer and edger.

A 3.0Ah battery is included, a little less than the 4.0Ah on the 13 inch brushless model, but enough for a small to medium lawn. It makes a good family tool, since one person can set the shaft to their height in a few seconds.

The thinner line and smaller swath make it a tool for light growth. Wipe the telescoping joint after use and keep the pack indoors in winter. If you already have a 24V mower or blower from the brand, the pack is shared, which makes the kit cheaper than it looks. Teach everyone who uses it to lock the shaft collar firmly, since a loose collar is the one thing that spoils a shared tool.

The BST4000 is the plain 40V trimmer for owners of the battery already. A 12 inch cutting path with 0.065 inch line and an auto feed head do the work, and a variable speed trigger lets you control the head as you move around plants.

The listing gives an operating temperature range, which is a useful detail for cold-climate owners, since lithium packs and plastic gears behave differently at low temperatures. It is a tool-only listing, so a battery and charger must be bought separately unless you have them from a mower or blower.

It is the cheapest way into the 40V trimmer line if you own packs, and a poor choice if you do not. Clean the head after each use and keep the pack indoors. A tool without a battery in the box is cheap only if you own the right pack, so check the platform before you order. If you do not own 40V packs, one of the 24V kits will cost less to start and weigh less in the hand.
