Factors to Consider when Buying a String Trimmer

Here are the following factors that you need to keep in mind when selecting the best string trimmer for your yard:

  • Engine Type. The first thing that you need to consider before buying a string trimmer is the type of the engine. A powerful engine can deliver a consistent and high-power cutting performance that is ideal for clearing large lawns. Not to mention that it also provides a longer running time so you can spend mowing your lawn for a couple of hours without interruption.
  • Feed System. When it comes to string trimmers, there are two types of feed systems that you can choose from. First is the bump feed system that will require you to press down on guard in a bumping manner so you can release the line. This system offers optimal control of how many lines are you going to use. However, this system also increases the risks of severe damage to your gardening tool because of the force that you need to exert. The second type is the automatic feed system. As the name implies, the trimmer will extend the feed line automatically as you go. To keep trimming, you don’t need to exert much effort. It is an ideal choice for people who have mobility issues as it can lessen the fatigue of using the trimmer even when used for longer periods. However, when an automatic feed system breaks, it is hard to fix on your own. It also does not give you the same amount of control that a bump feed system does.
  • Cutting Width. The cutting width of a string trimmer is typically around 12 and 14 inches in range. This width refers to the amount of space that the trimmer can cut in just one pass. If you want to finish trimming faster, you should opt for a string trimmer with a larger cutting width. It requires less effort and causes no fatigue. Other factors such as personal preference and physical abilities also affect in choosing the most suitable cutting width of a string trimmer. Some homeowners enjoy trimming their garden and use it as a way of exercising, so they opt for a smaller cutting width.
  • Convertible Options. If you are looking for a multi-purpose gardening tool, make sure to check if it offers convertible options. Some trimmers can be converted into trimmers. In that way, you can use your string trimmer in a variety of gardening works without having to purchase multiple gardening tools.
