The 18-Volt 10-in Straight Cordless String Trimmer and Edger is a uniquely designed lawn and garden tool that does the work of both a trimmer and an edger to save you time and money. All you need to do is flip the edge guide up or down to convert the tool as needed. An Automatic Feed Spool continues to replenish the line, so you’ll never have to take the time to make adjustments. The automatic starter is highly reliable and will power up the trimmer on demand each and every time. Powered by an 18-volt battery that can be recharged, the trimmer’s handle can be extended to ensure your comfort and ease of use. The trimmer weighs just 6.4 pounds and can be fully charged and ready to work in just 6 hours.
