I have both size machines... BX1870 and L2800. What you pictured for brush would just laugh at my BX. In order to pull that out I'd have to use the L and even then it would be a tough job. I cut them about 18". then wrap a chain around them about 12" up. Push/pull them back and forth a couple times with the loader and then the L will usually rip them out.I'm wondering if the additional weight would be a benefit. I'm also trying to clear brush with this and find it difficult and tedious to remove it. It doesn't like uprooting things, just bends them over or breaks them and leaves annoying little stubs.
