Hello all, I bought a Duratech hd 10 tub grinder and ordering if anyone one on here has one. Mine is the single axle version. My question is I am really happy with it. I on a landscaping company and grind all my stuff up and make mulch. I was just wondering if anyone knows how to make in Dra material in better and take bigger bits. I have the screen completely removed right now and it still cuts material in small pieces for the first grind. any Ideas to get it to the eat more. It currently has fixed hammers 9 across x 4
