I've considered it for my SCUT....I just don't like that it essentially makes the bucket unusable/less useful when it's on...as opposed to something like a Piranha or Everything Attachments toothbar. I looked at Heavy Hitch's toothbar, too.
I'm leaning toward EA or Piranha. I have some brush clearing on my winter to-do list...so the time to buy will be coming soon.
