- The NAC BKB40-2B40-S brushcutter is the ideal solution for users who demand high performance and freedom of operation. The 40V motor guarantees stable power, while three operating modes – ECO, AUTO, and TURBO – displayed on the easy-to-read control panel (page 12 of the manual) allow you to adjust the device's parameters to the type of vegetation and terrain conditions.
- The 300 mm cutting width of the trimmer head allows for quick trimming of grass and weeds, while the option of mounting a 255 mm cutting disc means the device can handle denser and taller vegetation. The automatic "bump feed" line feed system and the trimmer blade (page 14 of the manual) increase efficiency and reduce the need for frequent adjustments.
- The two-piece shaft tube, adjustable handlebar, and well-thought-out weight distribution improve comfort, especially during extended mowing sessions or working on uneven surfaces. Additional safety features—a cutting deck guard, switch lock, and battery charge level display—ensure user safety.
- The set includes two 20V 4Ah batteries and a dual charger, allowing for quick setup and extended operating time. The device's design allows for easy cleaning and maintenance, contributing to the brushcutter's durability and reliability.
Advantages:
- Three operating modes (ECO/AUTO/TURBO) – optimal power in all conditions.
- 300 mm cutting width with line – quick and efficient mowing of larger areas.
