The Different Types of String Trimmer Replacement Heads:


Before jumping into our best string trimmer replacement head reviews, let’s quickly go over the Three major types of weed eater trimmer replacement heads – so you can pick the right one for your trimmer.

The Best Weed Eater Replacement Heads generally fall into Three Different Categories:

These are the “Fixed-line”, “Bump-feed”, and “Automatic (or Speed-feed)” trimmer heads:


Fixed-line trimmers:

Fixed Line Trimmer Head – BestHomeGear.Com


This type of replacement head uses pre-cut lengths of trimmer line held in place by a locking mechanism. This head design does not require manually winding the trimmer line onto a spool.


Bump-Feed models:

Bump Feed Head – BestHomeGear.Com


The bump-feed type of replacement head does require winding of trimmer line – but allows you to go much longer between changes because of the large capacity of the trimmer line on each spool.  However, because of the large volume of the line used in a bump head, the trimmer line for bump head trimmers is usually a .065 lightweight trimmer line vs. the heavyweight .80 or .95 trimmer line.

In our opinion, bump-feed heads are the Least reliable, and often have failure delivering trimmer line consistently.


Speed-Feed trimmer heads:

Echo Speed Feed Head | Best Home Gear
Automatic (speed-feed) Head – BestHomeGear.Com


Also sometimes referred to as an Automatic head – Speed-feed heads are usually the most expensive types of replacement heads. And for good reason. They hold a good amount of heavyweight .095 trimmer line and you can change out a trimmer head in about 30 seconds.  Be sure to see the (Editor’s Choice) Shindaiwa video below – you will be amazed at how quick and easy it is to change the trimmer line.

A speed-feed head includes a built-in winding mechanism – that makes very quick work of weed eater change-outs.

With a speed-feed head, users feed the line into the trimmer automatically as it winds onto the spool without having to take the trimmer head apart.  Watch the video below to see how fast and easy re-spooling is.

Speed-feed heads tend to offer the very best combination of speed and convenience and are for this reason, most often used by landscape maintenance crews.

Beyond these three basic types of weed eater trimmer line heads, there are also a few Specialty varieties.


“Optional” – Replacement Trimmer Head Designs

Steel Blade Design

Certain companies offer a replacement trimmer head with “Steel blades” instead of a string trimmer line. A steel blade replacement head is generally used for trimming thicker weeds or brush. See Options below.

Plastic Blade Design

Alternatively, there are some replacement heads that offer “Plastic blades”. These heads while not offering steel blades, do offer a heavier duty application to cut thicker grass or weeds than traditional trimmer lines, See options below.


The 8 Best “Universal” String Trimmer Replacement Heads To Buy:

The following are The Best Weed Eater Replacement Heads you can buy and are compatible with “almost every String Trimmer.

We do recommend, that you consult each brand’s specifications to ensure the replacement head will fit your own weed eater model.

Editors Pick: Shindaiwa- “Universal” Speed-Feed

Runner Up: WW EZ Lock

WW EZ Lock Head

Why We Like It

In a twist on the fixed-line concept, the WW EZ Lock trimmer head uses two short pieces of .095 trimmer line-oriented into a loop. These replacement trimmer line pieces are inserted or removed using the two locking levers on the trimmer head body, making for quick and easy line changes.

This model fits on approximately 99 percent of gas trimmers, including both straight and curved shaft models.

Our Take Away

For the money, and with fantastic user reviews, we think it’s hard to beat the WW EZ Lock trimmer head. WW EZ offers replacement fixed-lines which allows you to keep the replacement head – and simply change the trimmer line pieces individually.

Because of this feature and its amazing longevity – WW EZ is actually considered a good choice for professional landscapers as well.

Best of all, it is an easy load trimmer head that uses pre-cut line pieces, preventing you from having to deal with the hassles of using a standard bump feed spool.

Best “Plastic Blade” – Weed Warrior Replacement Head

Weed Warrior 14867B Push-N-Load 3 Blade Head


Why We Like It

Turning away from a Fixed- Trimmer Head, we come now to a somewhat unique replacement head that features three plastic Blades instead of a string trimmer line.

The Weed Warrior 14867B is meant to cut thick, high grass and light brush quickly and easily. While blades on this head will wear out eventually, they can easily be changed by way of the push-button release found on the trimmer head.

From our research – new blades are changed out quicker than traditional trimmer line spools.

Our Take Away

With its unique design and great reviews – we think that the Weed Warrior 14867B is a very good option for homeowners who deal with dense grass and light brush regularly.

The blades are quite resistant to wear, making them preferable to the traditional bump-feed trimmer line design, especially for heavy work.

Why We Like It

This head Fits most gas trimmers. This very unique combination of blade and line replacement head offers the best of a regular .095 fixed line head and a bladed trimmer head.

Best Steel Blade for Brush: Grass Gator 4680

Grass Gator 4680 Brush Cutter Extra Heavy Duty Replacement Trimmer Head

Why We Like It

The 4680 Grass Gator trimmer head fits almost any gas trimmer and includes a steel-bladed head meant for tackling heavy weeds and brush. When mounted, this head can make short work of dense weed cover.

At just over one pound in overall weight, it is also among the most substantial and durable replacement heads on the market.

Our Take Away

We find the Grass Gator 4680 to be an excellent tool for going through unruly weeds, even on huge properties. One thing to note, though, is that it should be mounted on a reasonably powerful string trimmer for optimal results.

The manufacturer also recommends the use of this steel blade head – for gas trimmers 25cc or higher.

Like other universal trimmer head replacements, the Oregon Gator SpeedLoad is also extremely versatile and is said to fit about 95 percent of gas string trimmers on the market.
