What to Look for When Buying a Trimmer Head

How to determine a best string trimmer head

The trimmer head is the most important part of the trimmer because it is where you put the line that does the actual trimming. And so it is likely to come into contact with debris in the garden and stones or trees which means that you will need to replace it after some time.

Our string trimmer heads reviews above showcase some of the top picks in the market but to ensure that you get the right one for your particular machine there are some important things that you need to look out for when shopping.

#1. Type of Trimmer Head

The first and most important factor that you should take into account when shopping for a replacement trimmer head is the type. And this is because there are three different kinds and each is suitable for different string trimmers and situations.

#1. Fixed Head/Line System

The fixed trimmer head requires you to thread individual lines when you need them instead of winding an entire spool. These heads are ideal for commercial string trimmer and those that require you to use thick lines. The thick lines tend to break less, and so you do not have to keep replacing the trimmer line when using this head.

#2. Bump Feed

When using the bump feed head, you will need to wind some line on the spool through the openings in the head. Also, feeding new line as you cut grass is also very easy as you only need to bump the head on the ground. The ease of use and convenience make this trimmer head the most popular type for homeowners. However, the constant bumping of the head means that you need to replace it more often than when using other kinds.

#3. Automatic Feed

Most contemporary trimmers come with an automatic feed head that ensures that you never need to do any bump or manual feeding of the line. They feature a line spooling motor that pulls out more line without having to stop the cutting. The only shortcoming with these heads is that the spooling motor can be quite expensive to replace if it gets damaged.

#2. Single or Dual Line Head

To make sure that you get the best trimmer head you will also need to choose between a single line and dual-head lines. Both have merits and demerits, and you should consider your needs and the size of your lawn or yard when choosing between them.

A single line head makes it easy to wind new trimmer line, but it does not cut the grass very fast. The dual line, on the other hand, cuts twice with each revolution and hence finishes the job quickly but it takes more time and effort to wind new line.

#3. Compatibility with Your String Trimmer

No matter how good a trimmer head might be it will not work well for you if it is not compatible with your trimmer. And so it is always critical to read the specifications and features to make sure that it can work with your particular machine. Luckily, most replacement trimmer head manufacturers make their replacement heads compatible with most of the regular gas and electric trimmers.
