Tree surgeon/Arborist Timberwolf wood chipper grill? I have to ask this put somebody through the mill for any...

I have to ask this put somebody through the mill for any arborist or tree surgeon. I work for a company who have only just started to undertake their own grounds maintainence contract. I work as an arborist dealing beside all the tree related enquiries which come through. Me and my work colleague are both climbers up to CS39, both enjoy our RFS Cert Arb and studying level 3Tech Cert Arb, we are also qualified chipper operatives.

Now we are supervised by an operative next to no qualifications within arboriculture but he does have his chipper testimonial, he has ordered adjectives the shrub-beds on all the estates to be cut down, they hold been using the chipper to process the rubbish, yeah you got it, dishevelled brash, hiding all sorts of terrifying objects, stones, glass, metal. Now I know this will enjoy an effect on the cutting gears and pit the blades, so when I come to use it after them I am expected to put brash up to 7" diameter through it. Would you use this machine after them? if no, why?

Cheers
Answers:    Better to use a immense duty flail mower such as a McCullough as the brash will wear out the blades on the chipper.
i know nothing in the region of this but i would check it out with robustness and safety first.
