WORX WG163 GT3 Trimmer/Edger Review

Review of WORX GT3 Trimmer/Edger

Editor Rating: 4.6/5

Build Quality

Review Summary

The WORX GT3 Model 163 is a cordless 2-in-1 tool that does both trimming and edging work. It comes with two batteries (and a charger), so you’ll never be out of juice. It’s easy to use, with an adjustable height, front handle, and mower head. It has push-button line feeding and falls under WORX’s “Free Spools for Life” program so you’ll never be out of string.

This machine is ideal for homeowners with modest yard maintenance requirements. It will edge where your grass meets the sidewalk as well as along your flower beds, and it will trim grass along fences and around trees. It’s not a bona fide weed wacker and it will struggle if you try to use it as one so professionals are not really its target audience.

With this trimmer edger, WORX demonstrates once again that it pays attention to details and customer feedback. And with the shareable batteries and the lifetime of spools, it’s clearly hoping to build and maintain customer loyalty.

Good-bye, gas

Anyone tired of dealing with gas trimmers will greet this model with a smile of relief. No mixing gas and oil, no draining for winter storage, no spark plugs, no struggling to start – this WORX starts with a button and cuts your grass with minimal racket. It’s light enough to use all afternoon and doesn’t vibrate your entire torso. Fans report that they look forward to doing yard work because of this trimmer.

Two batteries for the price of one

If you’re at all worried about a cordless trimmer keeping up with you, worry no more because this machine comes with two batteries – one to use, one to charge – for about the same price as a similar WORX that comes with only one. Unless you’re trying to trim an entire Texas-sized ranch, you’ll have plenty of juice at your disposal.

WORX has been listening

In addition to including two batteries, to combat complaints about short battery life, WORX has also patented a line feeding system that works with the press of a button – meaning less string hassle for you. They’ve also included rubberized wheels, for greater stability and durability. And this model lets you switch out the included line for the industry-standard .065 line. All of this has been added without adding weight or messing with existing successful features like the adjustable head, height, and front handle.

Does this work as a mini mower?
No, this is only a trimmer and edger. The WORX GT2, though, has the mini mower capability.

Does it really take 5 hours to charge the battery? (That’s crazy!)
Yes, it does, which is presumably part of the reason a 2nd battery is included. WORX also sells a reasonably priced enhanced charger that can get this battery charged in less than an hour.

Aren’t cordless trimmers and edgers always underpowered?
While it’s true that cordless trimmers and edgers lack the gusto of a gas-powered weed-whacker, for the average homeowner, cordless tools like this one pack plenty of punch for trimming around your spouse’s petunia beds.

What the Users Say

There are essentially two kinds of reviews out there for the Work GT3 Model 163 – love it or hate it.

Reviewers who love it are thrilled they can take care of their yards without hauling around and dealing with a heavy, high-maintenance gas monster. By comparison, this is so light, quiet, and easy to operate that users no longer dread basic yard upkeep. These users have realized that the average regular Joe is usually cutting grass, not wacking down small oak trees or installing new flower bed edges. In other words, this is plenty of machine for any homeowner. The only real complaint from this crowd is that this model lacks the mini mower feature.

At the other end of the spectrum are those who were expecting the performance of a gas-guzzler. They don’t like that it won’t dig edges or take down a foot of thick grass, and they are disappointed when efforts to do so result in a rapid battery drain. These reviewers claim this is an underpowered toy and not for real lawn care.

Although most people don’t have much trouble assembling it, those that do are universal in their complaints about poorly written directions. On the upside, though, they have found that WORX has plenty of online videos that are much more user-friendly than the written directions.


If you have a smallish yard that you like to keep tidy, the WORX GT3 Model 163 is a terrific tool, and if you are coming off of a gas machine you will be particularly thrilled with this. Homesteaders, farmers, and professional landscapers – anyone with serious or all day wacking needs – will be happier with something more heavy-duty.

Remember Goldilocks? Not too big, not too small, but juuuuuust right? The same goes for you when choosing the right tool for the job. For most homeowners, this tool will be just right.
