Jerry, that truck was spinning it's tires in the grass before it went sideways. I'd guess dutch cuts and skinny/no hinge
And check out the radical twin hinge technique at 11.09
All of the above, Cory.
The blue fireball? Only heard about it. Looked green in the vid.
Gerr, what's wrong with pushing trees with a skidder arch, especially if the end of the arch has teeth to it? And you've seen that weird crazy hinging method before? That was a new one to me.
The smell is... indescriable...
You are pushing too low on the tree.
On big, tall trees you'll have a good chance of pushing it off the stump, rather than over.
