Tired of struggling with heavy, hard-to-start gas-powered string trimmers? You'll love this cordless, battery-powered mode. It packs the same power and speed, but without the hassle of mixing gas and oil. And it weighs just 11 lbs. — lighter than most gas-powered units so it's easier on back, shoulders and arms. No extension cords to trip over or limit your reach. The trimmer features a steel shaft, adjustable cutting widths and variable speed settings from 5100 to 6000 rpm. The lithium ion battery ensures operation at consistent full power until the battery is ready for recharging — unlike other types of batteries in which the power begins fading soon after you begin working. Includes battery, charger and .80" line spool. Made by Earthwise®, known for high-quality, earth-friendly lawn and garden tools.
