Coopers- we color our mulch by injecting liquid colorant into the grinding chamber of our grinder.
Krazy- that machine sounds like it might be good deal. Any pictures of the machines and attachments?
redneck farmer- Yes, I am a fan of CBI grinders. They can definitely put out some serious amount of ground wood. We finished that 95 job and are now 10 mins away in Haverhill on 495 clearing along the highway with the 160 before they repave it.
