650hp 3412 cat running 600yds/hr in mixed spruce bark with logs up to 12"x8'. If you will notice I'm running the tub backwards to slow it down enough so the loader can keep up. Full rpm tub turning forewords it will grind over 1000yds/hr with no hope of keeping up.
sounds like you need another loader to push up your pile!
Grinder is hooked to a truck to make a continuous windrow. Saves about 15 minutes an hour, makes $150/hour to have someone there to move the truck and grinder.
Hmm, well why not get a dolly and put a long draw bar on it and move it with whatever your using to load it witch im assuming is an excavator.
