WORX WG163.9 20V Cordless String Trimmer and Edger (Tool Only): specs

The WORX WG163.9 is a cordless string trimmer that converts to a wheeled edger. It is sold as a bare tool: the battery and charger are not included, so it is aimed at people who already own WORX 20V batteries. Here is what its features mean.

Tool only: what that means

WORX states clearly that this version has no battery or charger and works with WORX 20-volt batteries. If you do not already own them, you will need to get a compatible battery and charger separately. The listing says the box includes one 20V GT 3.0 trimmer/edger, a trimmer spool, support wheels and a safety guard.

Trimmer to edger in seconds

The cutting head turns with a pull and a twist to lock, which converts the machine from trimming to edging. For edging, the rubberized twin support wheels guide the tool along a lawn edge. WORX also says a flower-space guard protects plants and doubles as an edging guide.

Command Feed line

With Command Feed, you press a button to extend the line while you work, instead of bumping the head on the ground or turning the tool over. WORX describes this as single-line feed. It means fewer interruptions on a long edge.

12-inch cutting diameter

The cutting path is 12 inches wide, which is the width of the circle the line sweeps. A wider path covers more grass per pass, while a narrower one gives more control around obstacles. Twelve inches is a middle size for cordless trimmers.

Adjustments and comfort

A telescopic shaft with a quick-release lever adjusts to the user's height and posture. The shaft also tilts 90 degrees to angle the head for slopes and awkward spots. The front auxiliary handle has seven locking positions. The listing gives a weight of 4.6 lb in the dimensions field, while the description says about 6 lb, so check the weight in the manual.

Battery platform

WORX says its 20V MAX lithium batteries provide the power and run time. Running time depends on battery size, grass density and trimming style, so it is worth thinking about whether you need a spare battery.

Who it suits

It suits owners of other WORX 20V Power Share tools who want to add a trimmer without buying a second battery, and small to medium lawns where light cordless trimming and edging is enough. It is less suited to thick brush or very large lawns.

What to check before you buy

• Battery: confirm you own a compatible WORX 20V battery and charger.
• Lawn size: compare your trimming time with a single battery's runtime.
• Height: check that the telescopic shaft suits you.
• Line: check the spool type and how replacements work.
• Upkeep: follow the manual for cleaning and storage.
• Safety: wear eye and foot protection and keep the safety guard fitted.
