Better maneuverability due to lightweight design and the same powerful cutting performance as the current DUR187U series One protector for metal blade / plastic blade / trimmer head Toolless shaft lock for plastic blade change The guard integrated with receive washer minimizes weed winding Soft grip of ergonomic design; The same one as used on DUR368A series Comfortable band assembly with well-cushioned shoulder pad (DUR190U, DUR191U only); Increased cushion performance of the shoulder pad reduces operator fatigue Automatic torque Drive Technology (ADT) adjusts speed and torque during operation for optimum performance Active Feedback sensing Technology (AFT) turns the motor off if blade rotation is suddenly forced to stop BL motor delivers up to 6,000 RPM for faster cutting BL motor is electronically controlled to optimize battery energy use for longer run time per charge BL motor eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life Constant speed control minimizes reduction in rotation speed under load 3-speed options (Low: 3,500 RPM, Medium: 5,100 RPM, High: 6,000 RPM) allows the operator to match speed to application XPT (eXtreme Protection Technology) is engineered for improved dust and water resistance for operation in harsh job site conditions Electric brake for maximum productivity and increased operator safety Soft start feature for added motor protection Battery protection circuit protects against overloading, over-discharging and over-heating. On-tool hex wrench for fast and easy blade changes and keeping it from lost. Low noise level suitable for use in residential areas and public spaces. Zero emissions and reduced maintenance; no need for gas or oil. The best choices for use in resorts, public places and residential areas.
