Spencer, yep, there's still a lot growing - in fact, by the time I'm done grooming nothing but the pepper trees and grape vines that were too small for the big tractor and my root rake, I'll probably have a couple of more "normal" size brush piles. Next, I'm building one of those brush scoops that stick out like a vee with a couple of teeth on the end, because the little saplings fall between the teeth on the rake.
The rake is finished and worked almost as well as I expected. I don't have any working pictures (it was just too blamed hot to climb on and off the tractor), but here's a shot just before we went to work. When the brush was mostly branches and loose, we could fill up the rake. But, most of what we moved was totally crusted with dirt and tightly packed roots, so the problem that arose was the horizontal tube from the box blade, that holds the shanks, formed a barrier and we couldn't get large loads.
What we ended up doing was using the big tractor to move the piles (yep, every inch of that pile came from somewhere else, moved a rake-full at a time, into a headwind that blew the dirt back onto me), and using the little tractor to organize the piles and get them ready for the big rake. Sort of like using a broom to organize a dirt pile before sweeping it into the dust pan, but on a bigger scale. Two of us working took good hunks of 5 days to move it all.
Mike, I posted what the contractor told me about settling wile you were posting your question. He's been doing it for 30 years. Remember, it's mostly sand in the pile, and sand in the trench, so it should marry together pretty good. When you try to burn a small pile, you end up with a pile of sand about 6' high with some charred wood still in it. The wild grape vine was everywhere. We lowered the level of the whole property a good 3", and more in places, as we removed it. If we didn't, it would be invasive again in a few months. Things grow fast in Florida, especially the things you don't want.
