From 3.5 billion Reddit comments

I've been use this chainsaw tooth brush blade for about three weeks and am loving it. I'm using it on a Husqvarna 128LD 28cc string trimmer. It would work better on a 30cc or larger trimmer, but I wasn't wanting to buy something new.

I have bought 2 of these. https://www.amazon.com/dp/B015N8AV02 They are legit terrifying. Super effective. And terrifying.

There are chainsaw blades for weed whackers.

I'm not letting this thing anywhere near my ankles 😱

If you have the tools/knowhow to sharpen chainsaw chains, then get one that has chain saw teeth, not a carbide tooth. The carbide teeth aren't user sharpenable. I have this one https://www.amazon.com/gp/product/B015N8AV02

If you are tall-ish and not clumsy (I am neither), you might want to check this method out.
It would be easier than a lawnmower and you could cut the new growth much earlier / lower. The less green, the faster the mothership will die.
You attach a 9" round blade to a weed whacker and it cuts down brush.

I got all excited and bought this blade. But when I told my partner about it, he gave me *that* look and I realized it would be asking for trouble for 5' prone-to-daydreaming me to wield such a thing.

Thanks for the help!

Part of me wonders if I could go down to the 545 or 525 but given that it's a lot of small trees and I own 30 acres, I'm sure I'll get the use out of it. I assume you recommend sticking with the 555?

Also, what's your opinion on getting one of these blades instead? https://www.amazon.com/Forester-Chainsaw-Tooth-Brush-Bundle/dp/B015N8AV02/ref=sr_1_3?dchild=1&keywords=forestry+brush+blade&qid=1623429864&sr=8-3 I like that I could sharpen them since I have a chainsaw blade sharpener.
