Anyone have experience with a CMI Biogrind 175, horizontal grinder????

[Mowingman]

Anyone ever use a CMI or Rexnord Biogrind 175???. I am not all that familiar with these horizontal grinders. I have a lot of questions about their capabilities and their specs. Terex bought out CMI and no longer produces or supports these machines, so info is scarce.
Thanks,
Jeff
