The Best Universal Trimmer Head Buying Guide

string trimmer head

Several key factors determine whether a particular head is best. We took them as the benchmark during our research. Among them, the most important ones are discussed below. You should make a solid concept about these factors if you want to compare them. Anyway, let’s move on to the buying guides.

Types of String Trimmer Head

The first thing that comes to play in determining the best trimmer head is its type. There are mainly 3 types of trimmer heads available on the market. All of them are intended to meet different situations. So, you cannot tag any of them as the best. Each one has its own merits and demerits. So, let’s discuss them briefly.

Fixed-Line Head

The most common head that we use for heavy-duty or commercial purposes is fixed-line head. It doesn’t require to wind the spool to reload. All you need is to feed the individual line by threading it. As a result, this type of head can tackle thicker lines. So, you can use them for plenty of grass/weed eating. Thus, it saves your time and money. The maintenance cost for this type of head is minimal.

Automatic Feed

The most advanced type of trimmer head is automatic feed. You know the most frustrating job of trimming is line reloading. So, the manufacturers have taken the issue seriously and come up with the auto-feed head. It doesn’t take any manul action for line feeding.

There is a motor inside the head that pulls the line when necessary. It doesn’t stop the cutting during reloading. Inside the head, there is a provision for keeping the extra line that the motor pulls when needs. The auto-feed head is more expensive compared to other heads. But, if you want to get trouble-free operation, you shouldn’t mind spending a couple of bucks more.

Bump Feed

This type of head is very popular among homeowners. As it is suitable for cutting smaller yards, it serves better for home use. The winding of the trimmer lines needs manual action for this unit. The winding doesn’t require you to remove the head. There is an opening in the head that helps to feed the lines.

All you need is to bump the head on the ground. Then feed the trimmer lines through the opening. It is easier and convenient. The only demerit of this type of head is it consumes more strings. So, you need to consider keeping more lines if you buy this type of head.

Single Line Vs. Dual Line Trimmer Head

The trimmer head can be sub-divided into two types namely single-line and dual-line. As the name suggests, this division is based on the trimmer lines. The head that uses a single trimmer line is called a single-line trimmer head.

Similarly, the head that uses two trimmer lines at a time is called a dual-line trimmer head. The primary difference between them is their performance. The single-line trimmer head is easier to use and reload but fails to perform like the dual-line. On the other hand, the maintenance of a dual-line trimmer head is troublesome but produces great results!

Size and Grass Thickness

Another important factor that needs to be addressed before buying a trimmer head is the pattern of grass. The size and thickness of the grass have important roles to play. You need to buy the right weed eater head for the right type of grass.

The soft crops and thin grass can be tackled by most of the trimmer heads. But, you need to purchase a sturdy head for the thicker grass. The thicker grass needs thicker lines to be cut. Furthermore, you may go for the blades head for the thick grass. Even the combo of lines and blades may come in handy!

Size of the Head

As we know, “Big man for the big jobs”. Trimming jobs have levels. The home tasks vary depending on the size of the yards. The cutting professionals need something commercial grade for their jobs. So, a variety of jobs are out there. To tackle them, trimmer heads can be found from smaller to bigger ones. All you need is to calculate your trimming jobs and buy the head accordingly. The bigger heads can cut reasonably more than the smaller ones.

How Does a Trimmer Head Work

The trimmer head is one of the vital parts of a weed eater. It holds the string that cuts through. In most cases, there is a spool inside the trimmer head that holds the string in coiled-shape. The trimmer engine, be it a 2-cycle or 4-cycle engine, produces power to rotate the head.

The trimmer head rotates and ensures the string rotation that cuts the grass. The string wears out with time and needs to replace. Some heads offer auto string advancement and some need manual action. Some heads have blades instead of strings. In that case, the head rotates the blades.

How to Change String Trimmer Head Safely

Changing the weed eater head is fairly easy. The reloading/refilling of the trimmer line can be troublesome for some trimmers. But, the installation and replacing of the trimmer head is quite fun for almost every trimmer. To learn how to do that in less than 2 minutes, you may read our thorough article.
