This works exceptionally well on the knee high, woody invasive species in my greenspace. Durable and much easier to use than a string trimmer for these. I also love that the batteries provide long lasting power, seem to have more torque than my Troy Bilt gas equipment.
I was shocked that this attachment on a battery powered weed eater actually functioned as a brush cutter. I cleaned up thick over growth with ease and was able to cut right through 1 inch saplings.
