String Trimmer Buyer’s Guide:

Here are some things that you need to keep in mind while buying the best string trimmer:

Power:

The first thing you should check while buying a string trimmer is the power source. There are two primary models: corded/cordless electric trimmers and gas-powered trimmers. Both models have their own advantages and disadvantages. Thus, choosing the right power source depends on your preferences and lawn requirements.

Having said that, the cordless electric trimmer does have the upper hand since it doesn’t require any extension cords and is overall more convenient and efficient. However, a gas-powered trimmer is more suitable for heavy-duty tasks and larger lawns.

Shaft:

The next important aspect to consider is the shaft of the trimmer. You can find three major shaft types – adjustable, curved, and straight. Curved shafts are great for trimming hard-to-reach spots and offer superior control while cutting. On the other hand, a straight shaft is a better option for trimming narrow and tight space. Thus, you can choose the type that suits your lawn best.

Both curved and straight shafts are usually adjustable. Also, most high-quality brands offer adjustable shafts to perfectly match your height and deliver superior precision and comfort while cutting.

Feed lines:

String trimmers either use a single-line head or dual feed lines. The former is a better option for smaller lawns. They are also more convenient when it comes to refilling the lines. However, the dual feed lines are suitable for larger lawns and heavy-duty cutting as they cut twice as much grass with every revolution. 

Weight:

Weight is another important factor as it can affect the overall performance of your trimmer. Getting a super lightweight trimmer will not be the best option for heavy-duty tasks. Thus, depending on your workload, choose an ideal weight that’s not too light or too heavy.

Trimmers that come with weights ranging from 5 lbs to 15 lbs are quite portable and won’t cause much fatigue while working. 

Conclusion:

Several types of string trimmers come with different features. Additionally, there are hundreds of excellent brands that manufacture high-quality trimmers. Hence, choosing the right string trimmer completely depends on your preference and lawn requirements.

If you have a small lawn that doesn’t need much maintenance, you can go for a lightweight machine that comes with a single feed line and offers some decent cutting capacities. On the other hand, for larger lawns and tough weeds, go for more sturdy options, preferably with a high-powered engine.
