XGT Outdoor Power Equipment delivers gas-like performance demanded by professional landscapers. The 40 V max XGT Brushless Cordless Couple Shaft Power Head Kit with string trimmer attachment delivers the power of a 30 cc gas string trimmer. With zero emissions, lower noise and maximum versatility, the power head provides a cordless solution for heavy-load trimming and cutting applications. The power head features a lever-style lock system for quick tool-less installation and attachment replacement. Note that this item includes a 17" string trimmer attachment. A variable speed trigger controls cutting speed with three speed options (4,200, 6,000 and 7,100 RPM), allowing users to match power and speed to the changing demands of the application. For added durability in harsh job site conditions, Extreme Protection Technology (XPT) is engineered for improved dust and water resistance. The power head also features IPX4-rated weather-resistant construction for added durability.
