Brush blade on a flexvolt string trimmer

I've installed a 6-1/2in 40 teeth blade on my dewalt Flexvolt 60 volts string trimmer. Could not find any video on youtube about this modification so here's mine.
Power is more than enough. I suggest this modification AT YOUR OWN RISK since this unit is sold as a brush cutter.

Hello, thanks for the video. Can you make another video showing the blade adapter you used for that saw blade? I have a Dewalt DCST990 model, and I want to convert it to brush cutter but I am unable to find the correct blade adapter for it.

Like the others, can you make an installation video.

Which kit did you buy to convert the head to a blade. i just purchased the same trimmer. Also if i add a spacer would it work with larger blade say 10 inch?

I found the nut that fits the same head. From user peacefrob0521 on another video.
Nut m10 x 1.25, LEFT HAND THREAD. Found on Amazon it fits....YES YES

This is exactly the video I have looked for!! I need a brush blade for my Dewalt and can’t find one. We need an installation video? Does it rub on the guard?

We need an installation video. Or which kit works on this trimmer? I have the same trimmer.
