I got one stump up before the grubber broke. I was very pleased with the stump I pulled, just wish I could have pulled more. For perspective, the bar on the chain saw is 18".
As you can see from the photo, I cut the yaupon about two and a half to three feet up. I wanted to leave a nice bit of trunk to use for pulling up the stumps. I guess it will have to wait until. Dang.
