Why you should trust this review
We test string trimmers on a property with over 300 linear feet of lawn edges including sidewalks, fence lines, garden beds, and decorative stone borders. We evaluate both the standard trimming function and the edging function on trimmers that offer both capabilities, since this dual functionality is a key purchase decision factor for most homeowners.
How we tested corded electric string trimmers
Each trimmer worked through a standardized trimming circuit: 50 feet of sidewalk edging, 50 feet of fence line trimming, 20 feet of garden bed border, and a 5-foot area of mixed tall grass and weeds. We evaluated the quality of each operation type, line breakage frequency, and head pivot smoothness on models with pivot capability. Motor temperature was measured after the full circuit to assess thermal management.
Who should buy the DEWALT DXGST227CS?
Homeowners who want a single corded tool that handles both general lawn trimming around obstacles and clean vertical sidewalk edging without owning two separate tools. Suburban property owners with standard lawn edges, garden beds, and fence lines that require regular maintenance. Anyone upgrading from an underpowered budget trimmer that bogs on thick grass.
DEWALT DXGST227CS: the best corded string trimmer
The pivoting head converts the DXGST227CS from a horizontal trimmer to a vertical edger in a single motion by rotating the motor head 90 degrees without tools. In our edging test, the DEWALT produced a vertical cut quality comparable to dedicated edger performance, while competing fixed-head trimmers in vertical orientation produced inconsistent edge depths from head wobble.
The 6.5A motor handled our thick-grass and weed section without any audible bogging. Line breakage occurred once in our 5-foot weed section when the line hit a buried stone, which is unavoidable in any grass border with hidden obstacles.
WORX WG119: the best pure-trimming budget option
For homeowners who already own a dedicated edger and only need a trimmer for around-obstacle and fence line work, the WORX WG119 at a significantly lower price is adequate. The 12-inch swath and 5A motor handles standard grass trimming cleanly. It does not pivot for edging use. For the single-tool approach, the DEWALT’s pivot function earns its higher price. For buyers with a separate edger, the WORX saves money with adequate performance.
What to look for in a corded electric string trimmer
Pivoting head for dual trim and edge function. If you do not own a dedicated edger, a pivoting trimmer eliminates that purchase. Verify the pivot mechanism holds position firmly during edging; some inexpensive pivot designs drift under cutting load.
Motor amperage for your vegetation density. Five amperes handles standard short lawn grass. Six to 7A is needed for thick fescue, tall weeds, or dense growth along fence lines.
Cutting swath width for efficiency. A 12-inch swath requires 8 passes to cover a 96-inch fence line section. A 13-inch swath covers the same area in 7.4 passes (less time, same quality). The wider the better for large areas.
Line feed mechanism reliability. Bump-and-feed advances line reliably with light ground contact. Auto-feed systems advance line automatically but can dispense too much, leading to excessive breakage. Manual reload systems are the most frustrating to use during extended trimming sessions.
Frequently asked questions
How does a string trimmer differ from an edger?+
String trimmers cut vertically for general grass trimming around obstacles. Edgers cut horizontally for clean vertical cuts along sidewalks and driveways. Some trimmers like the DEWALT pivot to perform both functions.
What string diameter should I use for general lawn trimming?+
0.065 inch line handles standard grass and light weeds. 0.080 to 0.095 inch handles heavier weeds and tougher growth. Verify the trimmer head accepts the larger diameter before upgrading.
How do I prevent string trimmer line from breaking frequently?+
Avoid cutting at full throttle against hard surfaces like sidewalk edges. Let the line tip do the cutting, not the full line length. Keep line loaded to the correct length; too long causes whipping and breakage.
What extension cord do I need for a string trimmer?+
Use a 14-gauge outdoor extension cord for 6.5A trimmers up to 50 feet. For 100-foot runs, upgrade to 12-gauge. Use a brightly colored cord to avoid accidental cutting.
