The 18V LXT Brushless Couple Shaft Power Head Kit with String Trimmer and Pole Saw attachments is a welcome solution for a range of trimming and cutting applications. With zero emissions, lower noise and maximum versatility, the power head delivers maximum performance and run time without the hassles of gas and without leaving the 18V LXT battery platform. The lever style lock system allows for quick tool-less installation and replacement of attachments. The 10 in. Pole Saw Attachment provides 7 ft. fixed length for trimming hard to reach branches and the String Trimmer Attachment includes a rapid loading bump and feed trimmer head loaded with 0.080" twisted quiet line. The couple shaft can also be used with multiple other attachments for edging, cultivating, and brush cutting (sold separately). The Makita-built brushless motor delivers up to 7,000 RPM with String Trimmer Attachment and 3,940 FPM with 10 in. Pole Saw Attachment. Makita's efficient brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per battery charge than similar non-brushless tools.
