What to Consider When Buying a String Trimmers

Type – There are two main types of string trimmers: gas-powered and electric. Gas string trimmers are cordless, powerful, have two-cycle engines that require a mix of gas and oil to operate. Some gas trimmers are heavier which can affect the maneuverability. Electric string trimmers can be either corded or cordless and are turned on using a switch, rather than by pulling a cord like you would for a gas trimmer. Some come with battery packs, which can also affect the overall weight.

Cutting Width – The size of the cutting diameter directly translates to how wide a cutting swath the trimmer can make. Models can have a cutting width as narrow as 10” to as wide as 18”.

Weight – You will want to consider the weight of the trimmer before buying. You want a tool that is practical to carry around the yard for how ever long it will take to get the job done. The weight of string trimmers can range from 5 lbs up to 20 lbs, and gas-powered trimmers tend to be the heaviest but offer the most power.

Durability – Consistent use among heavy weeds and hard surfaces is where the difference in durability is determined. A more durable string allows you to do more work per spool. Trimmer string durability varies by material, the shape of the string, whats being trimmed, and surfaces used on, like stone or concrete.

Line Size – Line diameter is a good indicator of durability. Depending on the material and shape, a thicker line lasts longer but also costs more. Consider your cutting conditions, how often you want to reload, and how much you want to spend when selecting the line thickness. Not all lines fit all trimmers, so be sure to check the instructions before purchasing string for your trimmer.

Cost – With string trimmers, you pay for convenience and ease. Cordless are going to cost more than corded and gas powered will be at the high price point. Gas are usually reserved for bigger jobs than residential lawns because they are more powerful than electric trimmers.

How do I choose a string trimmer?

String trimmers are available in cordless (battery powered), corded or gas models. There are many features to consider like weight, cutting width and price.
