I know every locale may be different.
Around here though cutting a tree from public land without permission is a big no-no. Maybe the fence too is owned by some government agency. Don't know - should at least consider.
Pic seems to show ditch, right away and road on the side of fence that tree grew. Depends where OP is from would hate to have some gov't agency come down on him.
If that is the case...JUST DO IT ... LOLI'm quite sure Larry owns all the property shown in the close up of the treed area. No government owned land involved, and fence is his also.
I think LarryBud should have a "Spring Fling" and invite all willing Kubota tractor owners show up with their equipment for a weekend of work. Bring chain saws, chains and all other necessary play toys. He has mentioned working over some 10 acres of rough fields, discing, planting, etc. Divide up food cost and have a party!!!!
If nothing else just set around a fire and discuss how to safely remove THAT tree.
On a property that I used to own I was trying to cut down the bank next to the road so I could drive on to it. About 6 inches down I ran into a rock that my L1500 with a slusher wasn't going to move. I put a sign next to it that said "free rock " and I'll be damned if a neighbor with a track loader didn't come take it.LOL... Can't help but remember the old saying "There's a sucker born every day!"
Perhaps there is a chance of this working...
I had something like that once. A swamp maple that was still alive and about 8-10 inches around but leaning about 45 degrees. It became a comedy. First I tried to cut it and every time I would hear "crack, crack, crack" I would run away. I managed to cut all the way through and the sucker stayed right there! I made a second through cut about a foot higher up and nothing happened. I started to hit that piece when all of sudden I hear "crack, crack, crack" and the whole tree went up in the air about 10 feet and sat there horizontally on top of another tree! What the hell do I do now? Since I had plenty of other hurricane debris around, I decided to go and work on something else (I wish I had the tractor back then). After a while, I heard again "crack, crack, crack" and I see the tree coming down top first at about 45 degrees. So, I started cutting the branches and I noticed that the tree would slowly slide down on the other tree and I could keep on cutting the branches. By the time I got to the trunk, it was like "slicing bread" . I would cut a foot section and it would slide down for the next cut until I was done.Gonna throw this pic in just for fun. Dead ash about 80 ft tall, maybe 16 inch at base. Fell on its own. Got caught up in another tree, lifting the base about 10 ft in the air. View attachment 75330
