Have any of you ever had to clear out a raised planter bed thats full of brush that you don't want in it ?

HOW do you do it ?
It makes me cringe just looking at it- its full of grapevines and honeysuckle bushes.
How do I clear it out on my own?

any and all advice is welcome plz
thank U !

After doing any of this soak in a hot tub with epsom salts, borax, baking soda! Keep a dry towel close to hang over the tub for traction when you get out. Slippery.
