The video stopped at the good bit!

Video was taken by our engineer, it's at that point when you hide behind the bucket. Horizontal Grinders spit wood as the last bit goes through!

All that effort building a superb machine and an absolute joke of a vid. 
You should have got a 12 year old to film and edit that. 
Could not have done a worse job.  

Oh well! Only posted it here as it got 96,000 views on youtube in the last month

What does the cutting/grinding? What material can you put through it? Stumps etc or just clean timber?

This unit runs on a hammer mill and is great for general wood waste, including commercial & demolition waste. We have a chip drum kit for clean timber. Chris Tomlinson (owner) goes all over the UK processing tree surgery waste for biomass.

Are they cracks in the drum?!….

no, its water from the dust suppression system (hosepipe)
