Up to a certain weight, you can walk on tiles.
Its amazing what a BMG can do for bombed limbs where you don't have to worry about a bit of grabbing dirt (burning anyway), or a bit more tracking around. I got a dense pile of limbs for burning with little more than pulling levers, maybe 6' high, and 20' wide. A short time. When preschool resumes next week after Spring Break, parents will think I had a big crew in. Just me and an Ogre, so far.
Dave, Mr. BMG, said it before, moving brush by hand is the most waste of money around in tree work (something like that).
I did a big area of blackberry clearing, head high and more, 20' wide, couple hundred feet long. Pushing it all up with the bucket. Grabbed, compacted, rolled into a ball with the BMG, and loaded into my chip truck. If I could do jobs like that all the time, I'd quit tree work. Way too easy for the money/ risk/ strain on the body.
I'm going to push a 20x120' swath of black berries into the woods at another house. $325. Probably take me less than an hour onsite, with minimal travel and unloading/ loading. Just go there with the mini, bmg, and bucket.
Normally, if we are chipping, and in a residential setting. Stacking piles maximized the grapple-load, and narrows the pile for access, and lines them up for chipping. A lot more hand-work.
Even picking up big fir limbs and stacking onto small piles is possible.
How's the BMG coming Stephen?
