Here you go:
The story behind it was that I had a not very hazardous hazard beech to fell. I had calculated that if we could just winch it 15 feet over, before the rotten hinge broke, it would clear the wire fence behind it.
If it didn't, repairing the "keep the frigging semi tame fallow deer out of the new oak trees" fence would take an hour to mend, so no big deal.
So I let the apprentice handle it. He climbed up and set an 18 ton Dyneema rope in the tree and hitched it to the biggest forwarder on the market by way of a porty.
Then he started cutting the tree, correctly starting at the side it leaned towards ( you always want to do that on a rotten tree, so if it breaks off the stump while you are cutting it, you'll be away from the side it falls towards and maybe save BOTH your saw and your life!)
It was rotten enough that it settled on his saw, so he signalled to the forwarder driver to pull, so he could get the saw unstuck.
The forwarder driver, who'd been told that when it was time to pull, he had to pull fast to get momentum on the tree, thought the tree was cut through and did the closest thing to a burnout a forwarder can do!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Luckily the top didn't break out of the tree, the rope snapped but not before choking the hell out of the Porty.
It scared the shit out of the apprentice, who will now forever remember the importance of establishing a correct,failsafe procedure when communicating with operators of heavy machinery
The rope recoiled and ended up in the top of the tree, and the apprentice was too scared of life/trees/everything to climb up and get it down, so that task fell to me.
It worked fine, second time around. The tree fell at exactly 90 degrees to the facecut, clearing the fence by at least 15 feet.
I didn't have my camera that day, or I would have posted pictures of the whole thing.
I'm amazed the welding held up BTW.
