WORX WG163.9 is a battery powered string trimmer with cutting swath on 12 inches. It uses 0.065” string line and does 7,600 RPM at no-load.
It’s not something you would describe as powerful but for light jobs like cutting regular grass it’s sufficient.
Unit can be converted into edger. It’s not the best edger but it does the job.
You get what you pay for. Unit is made from cheap plastic
Although handle is (telescoping) adjustable it’s still a bit too short for someone who’s tall or has tall limbs. Overall balance is mediocre as weight distribution doesn’t feel quite right. It’s very lightweight though as it weighs just 5.3 lbs which decreases significance of previously mentioned flaws by a lot.
Overall ergonomics are average. They are not terrible but there is room for improvement.
There are multiple different batteries available for this unit so battery life varies. With a 2.0Ah battery you can expect battery life to be around 15 minutes, with a 4.0Ah around 25-30 minutes.
WORX WG163.9 advances 0.25” of line every time you release the trigger – so if you do it often to conserve battery life you will go through string fast.
Instruction manual is hard to understand.
WORX WG163.9 20V is a mediocre string trimmer but if you need one only for lights jobs then it might be sufficient enough.
