Best Universal String Trimmer Head Review and Buying Guide

Types of Universal String Trimmer Head

There are 3 main types to consider when buying a universal string trimmer head. They usually differ in the winding mechanism used, offering varying levels of convenience in reloading string trimmer lines.

Line or Fixed Trimmer Head

Fixed-line trimmer heads require individual lengths or pre-cut strings threaded or loaded into the trimmer head as needed. It eliminates the hassle of winding an entire spool of trimmer line, which is often a tedious process.

Fixed trimmer heads are best for use in larger string trimmers that uses sturdy and thick strings. They are best for units used in commercial applications. The downside with fixed head systems stopping the trimmer from replacing the line whenever necessary.

Automatic Feed

Most of newer string trimmers feature automatic feed trimmer heads. They feature a line-spooling motor inside that makes winding new string hassle-free. Auto feed trimmer heads are the most convenient to use as the unit does all the work, reducing downtime used for reloading new lines.

However, the trimmer head includes many moving parts, which are susceptible to malfunction after extended use. Once the spool motor breaks down, it can be a headache to replace.

Bump Feed

Bump feed trimmer heads, like automatic feed trimmer heads, uses spools of trimmer lines. However, instead of automatically reloading, bump feeds need a light tap on the system to refill the string, requiring a bit of downtime in between weeding sessions.

This type of trimmer head offers more control over the string length to use. However, the bump feed system is susceptible to malfunction and needs a replacement if that happens.

Trimmer Head Size

One of the first things to consider when buying a universal string trimmer head is if it can do its intended job. The size of the trimmer head defines what type or how massive a weeding works it can finish.

As a rule of thumb, choose small trimmer heads for small lawns or light-duty yard jobs. Meanwhile, heavy-duty weeding on expansive lawns will require a sturdier and significantly bigger trimmer head.

Compatibility

Getting the best universal string trimmer head would be a waste of money if it’s not compatible with the string trimmer on hand. Before purchasing one, make sure that it fits the brand and model of your weed eater at home.

Manufacturers are more particular on what type and style of trimmer head replacements work best on their units. Some part replacements will fit in most string trimmers, regardless if it has a straight or a curved shaft. However, trimmer heads for electric units are usually not compatible with gas-powered models and vice versa.

Single vs. Dual Line Head

Trimmer heads can use a single string or two, depending on its design. Each type has its pros and cons that need consideration when buying a universal string trimmer head.

In terms of convenience when reloading string trimmer lines, a single-line trimmer head is best. However, it doesn’t cut grass as smoothly or swiftly as requires for commercial and professional applications. Single-line trimmer heads, however, are suitable for most residential and light-duty yard care.

On the other hand, dual-line trimmer heads have more efficient cutting performance. They can cut through most types of grass and finish weeding at a faster rate. However, winding a new line on the trimmer head takes some effort and time.

Line Shape

There are various string shapes used for trimmers, and not every trimmer head accepts all of them. Most trimmer head replacements are only compatible with a specific configuration of trimmer line, so check before purchasing if you are particular about what line shape to use.

Common line shapes include round, square, twisted, star, and serrated. Circular lines are standard, and most trimmer heads can thread this shape. However, if you want to use more intricate shapes, which are sharper and cuts smoother, find a trimmer head that can thread that specific shape.

Durability

The best universal string trimmer head can be expensive, and you wouldn’t want to replace it frequently. In that case, find one that features a sturdy and rugged construction designed to withstand the wear and tear of tough weeding jobs.

Most trimmer heads use plastic material, so there isn’t a lot of choice in terms of material type. However, you can find models that use heavy-duty plastic that can withstand bumps on hard surfaces like rocks and pavements while weeding.

The quality and strength of the internal components also matter. As a rule of thumb, trimmer heads will fewer moving parts are less likely to break down and lose pieces.

Power Source

A universal string trimmer head can be either suitable for electric powered string trimmers or gas-powered models. Make sure to check its compatibility before purchasing one.
