Pulling a Fir (slightly) Sideways With the Truck

Hanging over the road there was a big leaf maple and three doug firs. The customer was understandably concerned about three large firs, one of them very dead, leaning over the road at a pretty serious angle; and wanted them all removed while preserving the big leaf maple.
The trees were growing in a pretty swampy area and maybe 20-30 years ago two had partly uprooted but hung on and began to turn and grow upright again at the tops. One of the firs must have died shortly after and was pretty well decayed and weak by the time this was addressed. The left most fir was underneath the maple and could just be felled from the ground, and with a little care so could the dead fir.
The third and last tree however had its balance and probably 30 feet of its top hanging over the maple. If one tried to fell it from the ground, it would have caught the biggest part of the maple and ripped it off, hung up (since it didn’t have the space to build up much speed) or ripped the entire maple tree down with it.
What happened was I set a pull line maybe 65 feet up the trunk, sent that to a redirect block roughly 90 degrees from the lean to create a side-pull and sent that to another block where the line could be attached to the truck at the road. The tree had some decay which I noticed making the face cut so I knew the hinge had to be left even thicker than normal for this situation. It was then aimed roughly in the middle between where the pull line was attached on the trunk and where the block was. The back cut is a bit tricky because you have to make it strong enough to hold the tree on its own even with a little pre-tension (so I could make the cut and get out of the danger zone before the pull was truly started) but weak enough the tree folds on the hinge exactly like you want it to. If the hinge was too small, it would break early, lose control and destroy the maple, to thick and you run into a whole bunch of other problems. With the hinge properly set I got way back and signaled to start the pull. It’s hard to tell in the video but the tree moved sideways a fair amount and just enough to clear the maple, then the hinge breaks and it starts falling straight down. Using the side-pull, the top landed probably 50+ feet where its lean had originally wanted to take it. The whole thing worked perfectly.
