Finding Your Next String Trimmer Head: A Buying Guide

Types of String Trimmers

Beginners find it hard to distinguish between the different mechanisms of string trimmer heads. Recent advancements in technology have led to a revolution in the designs and functions of gardening tools. Newer products have introduced more convenient features that help you complete the cutting and weeding process without putting in too much time or effort! You’ll generally find three types of string trimmer heads in the market.

Fixed-line trimmers

This is the most basic and conventional model. Basically, you cut down the string lines according to the length required for the given task. The exact cut piece is then placed inside the trimmer head which is installed over the trimmer. You can simply tap the trimmer head to the ground then and the strings will do the rest! We generally recommend this model for thicker trimmers so that none of the strings go to waste and the manual replacement time can be saved!

Bump-feed trimmers

These are slightly more advanced and highly feasible tools for homeowners. You can skip the tedious task of cutting an exact length of a string. You can instead place the entire line within the weed eater head and the installation process is quite simple. The string line can also be replaced once it wears out. Just like the fixed-line trimmers, the trimmer head is bumped against the ground and the product is ready to work upon your lawn. We prefer bump-feed weed eaters due to their affordability, effectiveness, and ease of use.

Automatic feed trimmers

This type is generally used by professionals in larger commercial gardens. The threads are placed inside the trimmer head which can then be controlled by an installed motor. The machine helps pull the thread rather than cut it. Although very convenient and effective these heads are generally very expensive. They also use a greater quantity of string threads and are hard to repair once malfunctioned!

What are dual-line trimmers?

You might be wondering why we didn’t suggest any dual-line trimmer head. These kinds work with two spinning strings making more pressure and cutting out stiffer weeds in quick time! However, they are expensive and also hard to load up. You might find the process to be complex and painstaking. Moreover, single-line weed eaters are usually good enough for maintaining a home-based lawn!

Features To Look Out For

No matter which type of string trimmer head you opt for, there are certain features that can never be ignored. These pointers help you make the right choice and select the ideal weed eater for your lawn!

The trimmer you have

String heads are specifically designed to fit certain trimmer models. You might find some designs to be extremely appealing but they’re worthless if not compatible with your weed eater. This will include the size, model number, capacity, and functional support of the machine. Always check for it before making a purchase.

Trimmer head size

You need to look at the density and general size of the trimmer head you’re interested in. Extremely light products may not be good enough and won’t cut through rougher grass. Similarly, extra-large weed eaters are not worth the money spent. They’re generally designed for fields with bigger weeds! A mid-sized weed eater will perfectly suit your lawn requirements.

Thread thickness variety

Some options are more versatile than others. They work well with a wide variety of spool threads ranging in length and thickness. This thickness determines how effective the weed eater would be while performing various tasks. While lighter options work better on edges, thick lines can easily wipe out the larger weeds on the center of the lawn. We suggest going for trimmer heads that support multiple string line options for a better experience over time.

Replaceability

String lines can either run out or wear away over time. You need a trimmer head design that can easily open up to place new spool threads every time this happens. This obviously isn’t a one-time hassle, that’s why it’s a key feature to look out for. We love models that come with a cap ready to open with a single tap. It makes the entire process simple and effortless!

Durability

Well, this is a key feature for any good product, isn’t it? Most trimmer heads are made using plastic and hence can be susceptible to damage! Therefore, we suggest trusting the more reputed brands. You can rest assured of the quality and excellent customer service in case of any one-off mishaps!

Instruction manuals

Gardening is an art. All the tools used in this process can appear to be complex for beginners. New models of trimmer heads can support various ways of installation. Thus the best products come with a precise guideline helping you figure out the entire process step by step.

However, if you want to watch a video tutorial on how to use a weed eater, this video from Lawn Care Life may be useful:

Value for money

Simple fixed-line trimmers can cost you as little as 20 dollars whereas more complex auto-feed options are available for 200 to 400 dollars. Do not get overwhelmed by the variety of choices available! Know your requirements and buy the ideal suit that helps you resolve those very issues.

People Also Asked

Q: Is a thicker string trimmer line better?

A: This generally depends upon the task at hand. Thicker lines are more effective at trimming long and rough grass. A 0.08-inch thick spool thread would work just fine for a regular lawn at home. However, the thicker options have proved to be more durable when covering larger areas.

Q: Should you soak the trimmer line in the water?

A: This might sound unbelievable but it’s actually a tried and tested method. String lines spin pretty quickly and hence tend to dry out. This makes it weaker and hence more susceptible to wearing out. Thus some professionals soak it in water before usage. This gives the thread a better grip and also makes it more flexible.

Q: Will the grass get stuck inside a trimmer head?

A: Some trimmer heads have a compact design. You’ll generally notice the lines tangling up within the tool. These models are more likely to get stuck with rough grass edges. More advanced models make for greater space and a better grip over the strings hence avoiding this issue over time.

Q: What is the best material for making string lines?

A: Nylon is generally considered the most durable material in this regard. Some manufacturers also add aluminum to further enhance its longevity and functionality. Polyethylene and Teflon are also commonly used to make more flexible strings.
