Product Description

The WORX cordless 20-volt MAX lithium powered grass trimmer with Command Feed has taken grass trimming and edging to a whole new level of power and function. With the 20-volts of MAX lithium battery power, the WG163.9 provides longer run times and more power. The GT 3.0 now features a command feed button to extend the line as you work. No more stopping and starting, bumping or turning it over to extend the line, just press the command feed button and continue to work. The 12-inch cutting diameter means more trimming in less time. Not only will this cordless trimmer convert to an edger in seconds, it has dual-positioned in-line wheels that make edging a breeze. A quick-release trigger lever is convenient for making easy height adjustments to the telescopic shaft for comfort and control. The trimmer head turns with a pull and turn to lock and convert to edging. From function to features, the 20-volt Worx trimmer and edger features 100% single line feed which means no bumping to extend the line. A flower space guard not only helps protect vegetation, it also acts as an edger guide. A front auxiliary handle has 7 locking adjustments for maximum comfort while trimming, edging, or mowing. Weighing in at only 6-pounds, this 20-volt grass trimmer/edger will create a professional looking yard with less work, less fatigue and less time. THIS IS A BARE TOOL ONLY AND DOES NOT COME WITH THE 20V BATTERY OR CHARGER. THE WG163.9 WORKS WITH WORX 20-VOLT BATTERIES.

Works well, get a battery adapter to run your current batteries

Works well, get a battery adapter to run your current batteries
I was reluctant to switch over to electric, but am pretty happy with my purchase. First, get a battery adapter to adapt your current 20v power tool batteries to the Worx trimmer, blower, etc. I own Dewalt, so I purchased an adapter here for $20. That way you save some money not having to buy the Worx batteries.2nd, don't expect it to cut like your old gas trimmer. It doesn't have the grunt that a gasser has, so if you have really overgrown edges you will have to slow down and let it cut at it's own speed. If your edges are trimmed weekly, it will handle it with ease. I'm an aggressive trimmer lol, and I had to learn to slow down and let it do its job. It cuts way smoother than my gas trimmer, and leaves a nice clean swath. It's more controllable than traditional ones, but take the time to adjust the head and handle angle to suit your needs, trust me on this one it'll save you some headache. Downside is my fingers get fatigued from holding the trigger down. Not sure why it's any different from holding the throttle on my old one, but I noticed it.Now the question everybody wants the answer to, battery life was great with a 20v 4ah. I basically have 3 yards, front, side, and back. With the back having extensive trimming needs. The 4ah battery lasted for all 3 and had one and a half bars out of 3 left. I was impressed. No noticeable drop in performance towards the end either.I also tried a cheap no name brand 20v 4ah battery with the same results. So it'll take whatever you give it.As for Quality, it feels like it should last a while. It's fairly light, and balanced ok. Line spools are very small, so I was worried about that, but I used way less line than I would have with my gas trimmer. Actually, I did all 3 yards without having to change spools. Oh yeah, get the pack of 6 or 8 extra spools, you won't regret the $12 investment. Overall, I'm happy with it and would buy again. Just remember to give it a few times of use so you can adjust to it.

Reviewed in Germany on March 1, 2020
Ichhatte mir vorher die neue Akkukettensäge von Worx gekauft und dabei 2 mal 20 Volt Akkus dazu bekommen, aufgrund der Werbung, dass alle Akkus zueinander passen, habe ich mir den Rasentrimmer für 20 Volt Akku bestellt. Die Akkus von der Säge passen aber nicht bei dem Rasentrimmer, es gibt einen Adapter, aber nur umgekehrt, dass alte Akkus in die neuen Geräte passen, ich hatte aber nur neue Akkus, die für alte Akkuhalterungen nicht passen, da der Preis sehr gut ist und eine Rücksendung nach USA mir zu blöde war, habe ich mir selbst einen Adapter gebaut, für die Fehlinformation deshalb nur 1-nen Stern
