The Makita DUR184LRT is a light but powerful trimmer that runs on an 18-volt battery with deep discharge protection. You'll benefit optimally from the power this cordless trimmer delivers, because the brushless motor is placed directly on top of the cutting head. It's equipped with an easily adjustable high/low RPM. You can work for a longer period of time at the low RPM setting, but high RPM setting is more powerful. Thanks to the electric motor brake, the string trimmer head will stop almost immediately, which makes it safe to use. The protective cover has been designed in such a way that you can enjoy full protection and still have an optimal view of your work. The DUR184LRT allows you to safely and effectively trim grass edges.
