The HART 40-Volt String Trimmer/ Blower Combo Kit is a great pair to keep your yard looking its best. The battery-powered string trimmer features an auto-feed head that releases a 1/2-inch of line every time you press and release the trigger. So no bumping required! It also has a 10-inch to 12-inch cutting swath. The cordless blower delivers up to 120 MPH of wind force blowing at 450 CFM, making it ideal for hard surfaces and general yard cleanup. Both tools are designed to be lightweight for user comfort and have a variable speed trigger for ultimate control. Includes a 40-Volt lithium-ion battery, which provides more than enough runtime for all your yard work needs. All part of the HART 40-Volt System where you get ALL POWER, NO GAS™.
