Re: I\'m stumped..
Jibber,
Let's put it this way. My B7500 didn't exactly jerk those things out of the ground. I would just go out in the evenings and pick away at them for an hour or so and eventually (many evenings later) I'd get 'em. I have removed about 8 large stumps or stump clusters this last year. This weekend I may be removing about a 14" spruce. Looks like a piece of cake. Am I sounding a little cocky.... It probably has a tap root that stops someplace just short of China. That's usually what happens when I get confident. As far as the big stumps, like I said, I have pretty nice soil to work with, so at least I wasn't fighting a lot of rocks or shale. I have mostly sand with a few veins of clay. But from my experience, significantly weakening one side of the stump after digging all the way around really helps to get it out. It also helps to twist the root ball. In other words, to grab a stout root on one side of the stump and try to spin it with your hoe bucket. That will usually loosen any tap roots. As far as topsoil, I have filled in these holes with the spoils and with a little light grading from the surrounding area, you'd never know they were there. In fact I have lawn where they were and it hasn't even settled. It seems like it would take a lot of soil to fill in for a root ball like that, but just a few inches from the surrounding area seems to work. Good luck with your project.
