Finally got my new duradisk installed and into testing. Definate improvement with my small grinder (carlton 2300). Ground 5 stumps 6-14" dia. in 20 minutes. This used to take 30-45 min. with fresh stock teeth on the old disk. This disk grinds much smoother (less vibration) and takes a bigger bite per pass. Close exmination after use shows absolutely no wear to teeth. Ground 2 white oak, 1 pine and 2 yellow poplar stumps in clay soil with no rocks. I have about 30 more stumps to grind, one being a 3' dia. gum, should prove interesting. I'll post results when I finish.
