Hoping to "group-source" with some other homeowners/renters here... I want to level an 8x8' patch of dried yellow bamboo shoots right at the ground. They're all twice the diameter of a pencil and tough as hell. A common brush cutter head on a weed whacker doesn't even faze them. I know. Checked out youtube and saw a couple demos of weed whackers with 80-tooth saw blades on them. Zip! Right through 3" tree branches, so I'm guessing they might do the trick on this much thinner bamboo as well. But who makes a rig like that (besides Stihl for nearly half a grand)? Once the bamboo project is done I'll only need the light duty weed whip to clean up after I mow. No attachments or anything - just a string trimmer. Any brands/models/setups you guys can recommend with the 80-tooth saw blade? Thanks in advance.
