I've got a 60" bucket on my B3200, so it's the same as your's on the B3030.
It works great ripping out small trees and brush. I burned a big brush pile last month and the toothbar came in handy pushing the brush up on top of the fire.
Here's a photo of what the Piranha looks like on the 60" bucket.
That's it.....I got a new B3200 and your post has me getting ready to buy the Piranha bar...... Now I can`t wait to get it ......
