Hey Bill what's up
the fist one I posted I actually own , it's got a 12v ctd in it
I took it to coffee night one time & guess what TMTT & the rest
wanted to do to it -- bomb it what else
I could have posted a tub grinder but the chippers get the point across better I think
hey Kev to answer you question , I know - I knew a few guys that had seen the inner workings of the smaller ones that are normally used in tree work , for most tree co. mine is just TFB for there every day use
oh & I also know one guy who went in a it & can tell you what he was thnking at the time
