Best Weed Wackers For Every Need (Buying Guide Included)

When shopping for the best weed wacker, you’ll be faced with several important considerations. You may have already made up your mind about some features, but do you know exactly what you want yet?

Sometimes it helps to check out a wide range of models so you can see what’s out there. That’s why I reviewed the five best weed wackers available today.

Maybe you won’t find what you’re looking for in these reviews. That’s OK. A buyer’s guide follows. There I’ve shared what you should have in mind when you browse for your next weed wacker.

Best All-Around: Husqvarna 128LD Gas Straight Shaft String Trimmer 

This machine may be all you need to take care of your entire yard, except for a mower, of course. You can get several attachments for it, including an edger, tiller and pole saw. On top of that, you can swap out the string trimmer head for a grass blade. That’s fantastic for huge clumps of grass and weed thickets.

You’ve got to have some serious serious power to run these kind of attachments, especially the tiller. Thats where the 28cc two-stroke comes in. It provides all the branch cutting, ground churning and weed chopping power you’ll need. And the straight shaft allows more torque to get to the head, where it needs to go.

It starts easy too. The recoil starter has the short-pull mechanism you may be used to.

I think it’s the best all around because it’s powerful, dependable and has enough useful attachments available to make it an all-in-one yard tool.

Best Selling Weed Eater: WORX GT 3.0 20V PowerShare 12" Cordless String Trimmer & Edger

Why is this the best selling? Probably because it’s totally affordable, yet is has a bunch of nice features that you’d normally only find on weed wackers at twice the price.

It easily converts from a 12″ straight-shaft trimmer to an edger. All you have to do is twist the head 90 degrees. The edging wheel saves time and gives you a professional result.

All comfort adjustments are easy and require no tools. To adjust the handle or telescopic shaft, you just flip a lever and set them where you want them. That saves time and hassle.

The 20-volt motor has ample power for edging and moderate trimming, but it would take extra time to chop through thicker grass or weeds. Charging time for the battery is a bit long at three hours. But if your trimming and edging usually takes you less than 30 minutes, you won’t need to recharge it.

If you just need a good, reasonably priced trimmer and edger, but you don’t need a lot of power, I’d recommend this one.

Best Electric Weed Wacker: Ego POWER+ 15" Cordless String Trimmer Kit with Rapid Reload Head

Cordless electric weed wackers sure have come a long way. This one rivals many and exceeds some gas models when it comes to power.

It’s got a 56-volt motor that’ll take a 15″ swath of tall grass down in short order. It’ll even take thick weeds like a gas trimmer.

The 2.5 Ah battery charges from totally drained to full in about an hour. That full battery gives about 30 minutes of run time. If half an hour isn’t enough for your yard, you can get a 5Ah battery for an hour of trimming.

So why is it the best electric model? Because it gives you the performance of a gas-powered weed wacker with all the benefits of an electric!

Best Commercial Weed Eater: Husqvarna 324L Straight Shaft Gas String Trimmer

Here’s a real powerhouse.

The engine is what impresses me the most. It’s a 25cc four-stroke. I love it because there’s no need for mixing gas.

If I had to clear a large overgrown lot, this is what I would use. The 18″ cutting width would get it done quickly. And there’s plenty of power coming down the straight shaft.

This one is pretty loud though. But aren’t all commercial weed wackers? Hearing protection is a must.

It’s too bad this thing doesn’t take any attachments. It would make a great edger. But there’s no better model for commercial or heavy residential use.

It’s the best commercial model because the four-stroke engine is very durable and powerful, and at under 12 pounds, it’s light enough for extended use.

Best Budget Weed Wacker: GreenWorks 21212 4 Amp 13-Inch Corded String Trimmer

Being on a tight budget doesn’t mean you have to settle for low quality.

You can get this tough little weed wacker at most places for less than $35. It’s a corded model, but that has some advantages. There’s no battery to drain. And since the battery is such a huge part of the cost of an electric model, you save a bunch of money.

The 13″ cut will handle big jobs, but it’s meant for more moderate trimming around your yard. It’ll do a great job at it too! The head rotates to get the edging done.

Many people think that corded trimmers are weak. That’s just not true. This one’s 4-amp motor has just as much power as a cordless 40-volt motor. That’s great for trimming.

This is my pick for the best budget model because it delivers solid performance at a sweet price.

Buyer's Guide

Couldn't find a perfect match in the list above? That's okay, there's plenty more to compare! Shopping around is part of the fun of getting a new weed wacker, after all. You want one that you’ll be happy with for years, right? Then take a look at my guide and shop with confidence.

Gas Or Electric?

Many people have a solid preference, while others are on the fence.

Most battery-powered electrics have a run time of 30 minutes per charge.. That’s enough time for most suburban yards, but you have to keep in mind that thick vegetation cuts this time dramatically.

Gas models are best for heavy use. Electrics are good for well-maintained yards and general trimming.

Corded electrics are cheaper than battery-powered ones, and most of them are just as powerful, but the main drawback is the cord.

How Much Power Do You Need?

Bigger gas engines and higher-powered electric motors usually cost more than smaller, lower-powered ones. Getting only the power you need can save you up to $100.

15cc to 20cc gas engines have plenty of juice to trim and cut through spindly weeds and thick grass. Once you get past 20cc, power increases dramatically. A 25cc engine can handle commercial use, and it’ll blast through thick weeds.

20-volt and 3-amp electric motors are good for light use. 40-volt and 4-amp ones correspond to larger gas engines. The ultimate power in electric weed wackers is found in the 60 to 80 volt range.

Handles And Comfort Adjustments

Don’t overlook this.

A weed wacker that doesn’t fit you can not only wear you out, it can be dangerous. You’ve got to.have control of it at all times. You can’t control it if you’re holding it awkwardly.

All but a few weed wackers on the market today have at least some kind of handle adjustment. You want a handle that slides up and down the shaft so you can get the right balance. This is the minimum adjustability you should settle for.

Some handles adjust for angle in relation to the shaft. This, combined with with the proper placement of the handle on the shaft, is all you’ll need to adjust the unit for your arm length.

Telescoping shafts are awesome. They just simplify the matter.

It’s a shame that more residential weed wackers don’t have harnesses. A good harness puts the weight on your shoulders instead of your wrists and arms. That’s a good thing if you have a lot of trim work to do, or if you have problems with your wrists.

Curved vs. Straight Shafts

Curved shafts used to be the most common, but straight shafts are the most popular today.

Straight shafts are more efficient, and are therefore more powerful, assuming all other factors are equal. They have better torque capabilities, so they may be your best bet if you have to whack tough weeds and thick grass often.

Another advantage of straight shafts is their ability to get under low obstacles.

Curved shafts are shorter and make for a lighter, better balanced weed wacker. If you want a light, easy-to-use trimmer and don’t really have anything you need to trim under, a curved shaft may suit you best.


Attachments may not matter to you, and I’m not saying that they should, but you may want to consider them before investing your money in a trimmer.

Do you ever have to borrow or rent a tiller, pole saw, hedge trimmer, leaf blower or brush cutter?

These are implements that are available as attachments for some weed wackers, like the Husqvarna 128LD that I reviewed above.

Of course these attachments are separate purchases that add to the cost of the trimmer. But they’re worth it if they are useful to you.

Avoid aftermarket attachments. Parts made by the original manufacturer are guaranteed to fit correct. That’s important because an ill-fitting attachment can cause excessive wear to the trimmer’s engine and components in the shaft.
