The 23 cm wide metal blade allows you to easily get through dense grasses and thick weeds. For lighter grass trimming tasks the blade can be replaced in no time with the nylon trimmer head which provides a cutting width up to 30 cm. The optimal line length is set during trimming with the automatic release mechanism by simply tapping the ground with the trimmer head. The 40 BCK has a total weight of 4.2 kg (inc battery not included) is very light and easy to handle. The 40 V / 5-Ah EnergyFlex battery with Li-Ion technology delivers enough power for 40 minutes of trimming – ideal for the home garden. An empty battery is recharged in about 2 hours.
