Yeah that looks like a lot of NO fun. Be interested to know how you manage it without some part of it dropping on the fence.
The tree was supported on the fence end somewhat by it's big limbs being on the ground. Was fortunate that it fell so close to the gate, as that is where the wire is strongly fixed to the sawed telephone post.
Got it done but not without trouble, the biggest problem was getting in there. It was in a small fenced off area where my brother had intended to build an elevated cabin, a small version of his beach house on 8' tall pilings, but was unable to live long enough to do so. I tried cutting enough out of the way to get my truck thru it but finally just went down the fence and cut the wires, then unloaded my stuff out of the truck and went home and got the tractor, walked up the trunk's angled part and tied a chain on it and pulled it off it's perch with the tractor, then pulled the thing along the ground and away from the fence. That's 14 ga Bekeart HT that's supposed to be able to support right at 1300 vertical lbs of force and 110,000 psi tensile strength. Pretty hard to break it which is why we use it instead of the cheaper classic Red Brand low carbon type or so-called "American Wire". It did force the gate down a little which makes it now a 'pickup and drag' type gate, but a lot of that probably came from having so much flood water run over it and I do mean over it.
Here's what it actually looked like before, tho the gate isn't visible thru the branches..
The fence is running left to right in the background and the gate is center of picture, partially open but obscured by the hated tree.
Done:
The fallen tree I moved off to the side and kinda piled what I had cut off on it but opted to leave most of it intact so the next flood didn't lift it and carry it into my fence which is about 300 yards to the South of this location.
As you can see, since I was on the tractor and didn't want to stop to return to the house, I had a few bobos I couldn't tend to. It doesn't take much to make me bleed all over the place.
and by the time I finished mowing everything I could, several hours later, it was dark and I had bled all over myself and the tractor and later, my truck. Another ruined shirt and another pair of stained jeans..
Such is life.
I'll have to go over there after while and repair the fence I cut so the cows don't get in it.
