Best String Trimmer Head

Lawn care does not just involve mowing but also using string trimmers at the end of the process. While a lawnmower helps cut most of the grass, the precise height and shape of the mat can only be obtained by trimming. String trimmers are of immense help in this. Weeding out tough grass and cutting hard-to-reach corner patches is made easy by these handy instruments.

A string trimmer has several components, one of which is the head. Since this is the part that does the actual cutting, it is important to find the right one suited to your needs. To make the search for the best string trimmer head simpler for you, we have curated a list of the top 10 choices recommended by experts. Here’s a quick lowdown.

Before going into detailed reviews of each of these products, beginners need to understand that there are three types of string trimmer heads. 

What are those? Keep reading for greater clarity.

Types of Trimmer Heads

The 3 basic types of trimmer heads that you can choose from are:

1. Bump Feed

Bump Feed

Bump feed systems work by tapping or ‘bumping’ the base of the trimmer on the ground during trimming. A portion of the lines or strings wound around the trimmer head are then released. These systems carry the advantage of using only as much of the line as necessary and what’s more, you are in control of that. 

A downside is that the spring tends to wear out over time.

2. Auto Feed

Auto Feed

In auto-feed trimmer heads, the line is released with the help of a motor. The system is, thus, automatic. 

What’s disadvantageous about such trimmer heads is that there will be a lot more of the line used compared to bump feed heads. Also, if the motor breaks down, repairing it can be a hassle.

3. Fixed Line

Fixed Line

Fixed line or fixed head systems employ particular lengths of string that are fitted into the trimmer head one at a time. 

While this allows you to have more control over the length of the line being used, you will have to pause your work to change the line every time it gets over.

Detailed Reviews for the Best String Trimmer Head

Now that we have seen the 3 main kinds of head systems, it is time to proceed to detailed reviews of our top 10 picks for the best string trimmer head.

1. PivoTrim String Trimmer Attachment Head

PivoTrim String Trimmer Attachment Head
Check Latest Price on Amazon

Compatible with 99 percent of gas trimmers, the PivoTrim String Trimmer Head is an exceedingly practical product. It fits eight strings to increase the number and efficiency of the cutting lines on your trimmer head. With more lines whacking at the weeds and grasses, it is faster and easier to cut them down.

The construction of the strings is meant to be durable besides being powerful and precise. This is achieved by a pivoting mechanism which makes the strings project out at the grass at high speed. However, when the lines encounter more-than-normal resistance, they pivot out of the way, thus reducing breakage.

Additionally, changing the strings takes next to no time. Just add a pre-cut string into the pivot and pull tight. Repeat that for all the pivots that need loading and you’re good to go. This can be done in a few seconds and without much trouble.

What We Liked

  • Universal fit trimmer head is compatible with 99 percent of trimmers
  • Breakage-resistant strings
  • Eight pivoting lines for faster cutting
  • Inexpensive

What We Didn’t Like

  • Pivot pins sit in a plastic casing which can melt and jam the mechanism on overheating
