It would be interesting to record the hydraulic pressure umpteen times per second and estimate the uprooting force per tree. With strain gauges along the length of the jaws, the point of contact could be estimated. That and the jaw closure angle could be used to estimate the diameter of the tree.

I wish your time Kerrie, and one twig all the way back put a bunch of them. I’ll pull the whole tree for God sakes, unless you like wasting fuel.
