Zago shredder versus the stump

We try to re cycle as much of our green waste as we can, what the tree team cant chip we shred with the Zago. We also take in uncontaminated green waste from other tree companies and landscapers. The end product is then used as a soil conditioner, or screened to produce an allotment grade compost. I would not normally put such a big butt end stump through the Zago, but it was quite old and decayed so thought it would go through OK. the video is made up from at least three different timelines, the observant among you will surly notice, so better to come clean from the start.
