For this post, I have put together a collection of the best string trimmers currently available.
UPDATED: August 28, 2019.
During two summers in college I worked as a grounds keeper for a school district mowing lawns. I remember how satisfying it was to put the final touch on a grassy field by using a trimmer on all of the edges. Making a clean line where the grass meets a sidewalk or fence really makes a difference to the overall look of a lawn.
Also known as "weed eaters", these simple yet powerful tools operate with gas, electric, or battery powered motors mounted on the upper portion of the handle. This drives a head at the bottom that spins a nylon or monofilament line at high speed to quickly cut through grass and weeds.
The cutting action wears down the line but can be replenished by bumping (tapping the hub on the ground). The hub acts as a dispenser that stores a spool of line similar to a fishing pole. Some newer models below feature a push button that extends more cutting line.
The following string trimmers use the latest innovative components to meet your needs and help to ensure you do your best work.
