Trimmer has ECO mode

The WORX Nitro 40V, 15” Brushless String Trimmer uses two WORX Power Share 20V 4.0Ah MAX lithium batteries to deliver 40V of power and performance. The trimmer features a high-efficiency brushless motor with extended run time. It runs cooler with less friction and heat buildup than conventional motors, extending the tool’s life. It has a dual feed .095” professional twisted line that uses a quick-load line replacement system. The trimmer has variable speed control and a push-button ECO mode to conserve battery consumption when trimming sensitive areas such as flower beds and vegetable gardens.
