The unique design of this system ensures that you’ll never have to contend with messes. Likewise, this well-thought-out design makes sure you can reload the line on your own.

In other words, long gone are the days when it took two men and a boy to reload a string. In fact, with this particular model, you can load up to 20 feet of line in less than a minute. Can you beat that? Above all, you’ll not need any specialized tools for the assembly or disassembly process.

6. Husqvarna Universal T35 Tap Advance Replacement Head 537388101

Husqvarna is known for many things and compromise is certainly not one of them. Clearly, their awesome product the Husqvarna 537388101, an under $25 universal string trimmer replacement head fits the bill.

A closer look at it reveals that it’s an automatic line feeder. This eliminates all the hassle and leaves you with the freedom to get started on your work with minimal delays. In fact, all you need to do is push the head into the ground.

And to make sure your user experience is at its best, the head comes with a package of adapters. These adapters come in handy when you need to attach it onto string trimmers from other brands.

We, however, genuinely believe that this head is optimized for Husqvarna trimmers. So, if you’re looking for a genuinely universal replacement head, this might not offer the best kind of experience.

Likewise, although this system is pretty easy to fit on all Husqvarna trimmer models, we aren’t sure how it’d perform on other nondescript trimmer brands. Moreover, the process of installing it using adapters might be a little complicated than average.

Otherwise, this is a powerful replacement head. It works great, most of the time. It is hardy and can last for long. Most importantly, it can be used on a few other string trimmer brands other than Husqvarna.


  • Hardy and sturdily built.
  • Extremely easy to feed line.
  • Creative spool design which reduces tangling.
  • Has arrows which direct you on the correct directional winding.
  • Two handy key slots for locking in the trimmer line.


  • Seems best suited for Husqvarna brands.
  • Accommodates a maximum of .095-inch trimmer lines.

7. Pivotrim Maxpower .095-Inch Replacement Head (3317233)

What if your replacement head came with a premium pre-cut line? Well, for those looking for the best string trimmer replacement head under $20, the Maxpower would represent great value for money.

It’s designed to fit almost all major string trimmers. Moreover, it is painlessly easy to install. Want to load the line? This one comes with easy-to-use eyelets and an incredible spool. And so, the minute you start using it, you’re bound to enjoy having it.

A closer look at its capacity reveals that it can accept lines of between 0.080 and 0.095-inch diameters. These two diameters are pretty powerful although not exactly heavy-duty. In other words, you can bank on this head to handle medium to light-duty commercial work.

It may not be ideal for extremely heavy-duty work. But at its price, we think it represents good value for money despite its limited capacity.


  • Affordably priced.
  • Has a pivoting feature for limited line breakage.
  • Fits almost all trimmer models.


  • Not suited for heavy-duty work.
  • Its housing is a tad too delicate.

8. Weed Warrior EZ Lock Head 16741B

The WW EZ Lock Head often ranks on top of best replacement heads for string trimmer reviews. But what makes it so unique? Well, we’d say that it’s extremely easy to install. Its instructions are pretty straight-forward though, in reality, not many people even bother to read them.

The head is slightly hardy. You can use it to tame woody stemmed plants. Besides that, you can even operate in areas near wire fencing or concrete with no worries.

So, if you’re looking for a powerful replacement head that can last you for many years, this might be it. Likewise, if you’re after a model that doesn’t flinch easily, this has got to be it.

We think the best head sizes for this trimmer is 0.80” or 0.95”. However, the manufacturer insists that the WW EZ Lock Head can still handle a 0.105” unit. Of course, you can agree that even if it handled .105” line, it still wouldn’t be hardy enough for heavy-duty tasks.


  • Extremely easy to use.
  • Medium-powered for domestic and light commercial tasks.
  • Built to last.
  • Compatible with most string trimmers.
  • Highly user-friendly.


  • Not as rugged and heavy-duty as you’d expect.

9. Oregon 55-491 String Trimmer Head

How much more would you enjoy using your string trimmer if you had an intuitive attachment head? Well, if you really love your trimmer, you should perhaps consider getting it an Oregon 55-491 replacement head.

Designed for heavy-duty trimming, this head can accommodate 0.105 strings and smaller. Of course, the stronger the line, the shorter it will need to be. Vice versa applies.

From the look of things, this head is best suited for professional landscapers. That said, you can still enjoy using it at home especially if you’re facing a serious challenge with weeds.

What about universality? You might be wondering. Well, all we can confirm for now is that this head is capable of fitting 99 percent of all straight shaft trimmers.

Moving on, we think that the construction of this head is pretty decent and robust. It should last for long provided you use it for the job it was originally intended for.

But there’s one downside with this machine. Much as it’s a heavy-duty head meant for commercial use, it only accommodates a maximum of .105” line. That’s not the heaviest duty line available!


  • Easy to use.
  • Sturdily built.
  • Stronger than your average replacement head.
  • Can work with both gas and electric string trimmers.

Have you been looking for a user-friendly replacement head for a string trimmer? Worry no more because the Homelite 308923014 might be all you need. Here are a few quick pointers.

This system comes with an irreversible spool on the inside. The good news is that once you load it, you’ll not need to keep it open. And what’s more? This system is quite hardy. It operates in a great sweeping motion and does a stellar job while at it.

From the look of it, this replacement head is meant to hold a 15 feet 0.095 string. However, if you’re looking for greater leverage, you can always use a 20 feet 0.080-inch string.

Basically, all one needs to do is rotate the knob in order to line up the slot with the eyelets and arrows. Once that’s done, simply thread a full length of the string in just the same manner you’d do when lacing a shoe.

That said, this system feels a little heavier than average. So, you might have a bit of a hard time trying to balance it. Other than that, we think this is an awesome head replacement.


  • Easy to use.
  • Hardy in design.
  • Extremely easy to wind.
  • Can be used on different trimmer brands.


  • A bit heavy and tricky to balance.

Buying Guide

To this end, one thing we can all agree on is that the head is the most important component of the string trimmer. So, you wouldn’t want to compromise on it. In that regard, here are a few quick tips to remember when shopping for one.

# Different Head Types

There are 3 common types of heads for string trimmers. These include the fixed/line, bump, and automatic feed. The fixed/line is one that requires you to thread the line in the head instead of winding the whole spool. The bump feed variety is known for the constant bumping of the head. In fact, you’d need to replace the string quite often on the bump feed type than in any other string trimmer head type. Lastly, we have the automatic feed. This one makes the job of weeding the line way easier. It comes with a line spooling motor that pulls out the line without interfering with the cutting.

# Type of Work

Whether you’re planning to do some DIY cutting at home or thinking of going fully commercial, the kind of head you go for matters. If planning to use it at home, then we’d recommend going for a .080 to 0.105-inch type. However, if thinking of going fully commercial, we’d vouch for a head capable of accommodating a thicker line (.105-inch and above).

# Compatibility

Be sure to read all the provided specifications. In particular, be sure to confirm that the replacement head is compatible with your trimmer. Fortunately, our review includes some replacement heads that are compatible with different head types including those of electric and gas trimmers.
