A root grapple is nice, especially if you're chipping the top's and brush. You can pretty much shake the dirt out of them. I assume you're not too worried about disturbing the grass from your post, if that's the case you'll want a bucket or blade handy if you need to smoothe thing's out when you're done.
I have an old Thomas grapple bucket and I like it pretty good. When you get used to it you can pick up most top's & brush without picking up dirt & rocks.
With this setup I can finish an area up and smoothe thing's out without having to carry an extra bucket to the job. The Thomas bucket is built pretty heavy, and stand's up to abuse well. I've put mine to the test for the last 5 year's, and it's still in good shape.
