FAQs

What are some features to look out for in string trimmers?

The Engine Type

The engine type is a crucial factor to consider, as it influences many other decisions regarding your choice of string trimmer. The two most common types of engines are electric engines and gas-powered engines. Gas-powered engines tend to be relatively larger in size and more powerful, making them best suited for heavy-duty tasks. On the downside, they can be somewhat costly to maintain as they require gas fuel to operate. Additionally, they can tend to result in unpleasant emissions or be loud when operating them.

The electric models either have a cord that requires you to plug it into a power outlet or operate on rechargeable batteries. Electric weed whackers are generally less powerful, although they have different variations to them, with motors having a fluctuating degree of torque, which affects their overall output. The battery-powered engine models offer you more mobility, although they require you to charge them every now and then. The corded ones do not require you to stop working to charge them, although they are more limiting in terms of range. Make up your mind on which of the two to go for depending on your power source availability as well as the size of your yard.

The Average cutting width

String trimmers come in different cutting width, usually expressed in inches averaging between 12 and 14 inches. The cutting width refers to the space in which the tool can properly trim down weeds or grass, without necessarily having to move the unit. A string trimmer larger cutting width allows you to cut more with little to no effort, which is ideal for anyone who has a big yard and wants to get the job done faster. A trimmer with a relatively small cutting width is best suited for smaller yards. They are usually smaller in size and are much easier to handle. The cutting width does not necessarily operate on the ‘bigger is better’ principle; your decision is dependent on your yard’s needs, your physical ability as an individual as well as your comfort in operating the tool.

Feed System

When it comes to string trimmers, there are two predominant feed system styles. Feed systems refer to the mechanisms that control or determine how much of the ‘string’ gets fed out through the head. The bump feed is the traditional type. It requires you to manually press down on the guard in a bumping kind of motion in order to release some more of the line. This approach gives you better control in terms of how much line you get to use. The downside to this system is that it increases the chances of you damaging the trimmer, given that you have to exert some force to smash the trimmer on the ground.

The other type of feed system is the automatic feed. It is much easier to use as the trimmer automatically extends the feedline for you as you go; there is nothing special that you have to do in order to keep trimming. The downside to this is that they can prove to be quite difficult to fix once they break down as you do not have any level of control.

Weight and Size

Just like with any other tool, it is important to consider your string trimmer’s weight and actual size, just to ensure that you are in a position to comfortably use it. A tool that is ideal for big yards would be larger in size as compared to one suited for smaller yards. However, it is of little to no use if you cannot actually handle it. If you have joint problems or even any kind of disability, then the weed whacker’s size as well as weight are some determining factors in your tool of choice.

What is the essence of Convertible Configurations?

Nowadays, most string trimmers have convertible configurations as an additional functionality. One such example is the ability to change your trimmer into an edger, which allows you to make clean cuts around the edges of your front or back yard. If you have a flower bed or an area where the grass meets the pathway, then an edger is the most ideal tool to use to make nice, neat and precise trims. While this feature does not affect the primary purpose of your string trimmer, it is an added advantage in case you might need to use a trimmer.

What are some of the safety features in string trimmers?

When using any kind of tool, your safety as the user is key. A majority of weed whackers in the market today have an element of safety, implementing some great features that keep everyone safe. One thing to look out for to ensure that your device has got you covered when it comes to matters safety is the presence of a solid safety guard around the head. Additionally, go for a string trimmer that does not require you to come into close proximity with the head when it is operational.
