Silvey tree jacks are made just for jacking trees. Each ram is capable of 62 tons. In the following video, we used 4 rams:

I've never understood making the diagonal cut first on the face cut? Doing it that way, aren't you limited to the 'gun' you put the saw in at... By doing the horizontal cut first, you can adjust the 'gun' before making the diagonal cut. Lines up easy, in the direction you want it to go.
Cody, Are you in that video? I have watched that a million times.. How cool!
Fairly heavy duty tool

Glad I could help...
We are planting 12000 Abies Normanniana for x-mas trees right now, in an area that was prepared by running a smaller version of that machine over it.
While it is certainly nice that all stumps and debris is gone, having to dig through 5-10" of schredded wood in order to hit soil is not.
the last company i worked for had a grinder similar to that but there's was mounted on a 330 cat excavator had a separate power unit to drive the grinder, talk about a blast to run, the only hard part about running it was showing restraint...
