Like Sweet K30,I've had to pull several hung up trees over in the past,and been "lucky" as far as no injuries (at least to ME,not counting other objects!)--and still have one threatening to cave in my quonset hut some I haven't been able to deal with when all the trees around it had their leaves on still..its being supported by a chain bolted across two other trees beside it..it has dropped onto the chain and is about 8 feet from the top of the roof now..tilted over much more than in this older photo..
There is another tree in my yard right near the street about the same size as yours is,and it landed right in the crotch of another tree and wedged itself firmly there,the butt end is stuck into the ground a good foot..that one is going to be tricky to pull free because its near the road,and right on a property line ..luckily its not very high up,maybe 8-10 ft..
I like the idea of using a snatch block and have in the past,to let me pull a tree down and be safely out of its path..you can double them up and gain pulling power too..
I have had limited success using ropes to pull trees down,more than one time the brand new nylon rope snapped after stretching a lot ,when the tree began moving and lifted a few feet--SNAP!..and it crashed back down ..was lucky things didn't go bad cause of that..
Whenever possible I use chain or cable,but its a chore getting one up on the top end of the tree,especially the 50 foot length of 5/16" chain I use --I've had to use a fishing pole to let the fishing line up over the tree,hope the sinker lets it drop so you can tie a nylon rope to it,reel it in,get the rope over the tree,then tie it to the chain or cable and repeat,till you have it in place..this is a real ballubuster when other trees with lots of branches surround the one your aiming for--the line will spin onto another branch several times ,totally pissing you off,at least when its me trying to do this..

..
I now have several lead sinkers permanently stuck in trees,so I've started using large hex nuts ..

I've also had a metal pipe I used as weight to toss a rope over a tree,come off and clock me in the head as I was twirling it around in cowboy fashion to get it up over the tree..times like that I wish I had a spear gun,or maybe a bow & arrow..
In the past I had friends with a wrecker boom or ramp truck ,and we used the winch to pull hung up trees down..we put a snatch block on a nearby tree about 10 feet higher than the hung up tree and looped the winch cable to it so it would lift the tree up and off the other it fell on and wedged in,and the tree swung itself free once clear of the other tree and we were able to just let it down slowly...one other time the tree snapped off like a gunshot and the tree crashed to the ground and the rest of it was dangling from the cable..

..
A few times the tree was so firmly wedged,we just rigged up snatch blocks to pull on the center of the tree and snap in in two from a safe place..
I have yanked many trees down with my pickup and garden tractors,but it is tricky to get the right combination of throttle and hard to see what your doing when its behind you..
I once went to pull a maple tree about 6" thick out that fell against some trees right next to it..my truck pulled it right out like a bad tooth--when I got out to unhook the rope,I was surprised to see I pulled 2 other equal sized trees out too,and they took out 25 feet of cedar fence..

..
I think at least 3 professional tree service workers have died here in MA in recent months..bottom line is its a huge gamble,trees can do what they want,even defy physics, despite you having the skills and knowledge to give you the best shot and downing one without getting killed or hurt bad..even experts die doing it..
I'm not in good enough shape to cut trees like I used too--I should hire someone legit to get that tree down before it falls on the garage..they have insurance--if I end up dropping it on the garage,I'd likely be told "self inflicted damages aren't covered"..
Right now my best friends dad,who is in his early 70's,was finally able to go home from a nursing home-rehab center--he attempted to climb a ladder about 25 ft up a tree a few months ago ,he wanted to cut off branches to allow more sun to get on his garden--he was using a big brush cutter knife (Machette ?) to lop them off,he lost his balance when the ladder moved,and down he went--the knife got both of his arms as he bumped off branches as he fell,when he landed he broke his collar bone and three ribs,and had a punctured lung..he was lucky to live,and still has a long road to recovery--he admits he was "stupid" to do that alone..
He's been a farmer/factory worker all his life and was in excellent health prior to this--I saw him climb a 50 foot tree with a chain saw in tow and lop the top off the tree about 10 years ago...no fear,strong as a bull..
