The photo below is that exact tree over on it's side.
20 tonne bottle jack, had to reset it three or four times. Kept putting the jack plate up and through the butt of the tree. I've since made a new jack plate, that is 150x150mm instead of 100x100 that will give more spread hopefully. 
 

I've had 2 20 tonne bottle jacks and all my wedges in a tree before that was a little bit worse than that one but heavily back leaning. Took a two fills on 70cc saws to sned it out half way. 

On a tree of that size bring your mouth further back towards the centre of the tree. Bringing the pivot point back means less effort to get the bugger over.

Wind is always a bugger for messing up trees as they fall, add a sizewheel or thicker hidge on the windward side which may or may not help.

That's not what you want to do. You load up the back even more doing that ,higher chance it drifts off the stump during the fall too.

If wedging or jacking that’d mean more effort needed to smack the wedge in/Jack pressure as you’re effectively shortening the leaver effect……but you wouldn’t need as much height in the back cut to tip it over

I saw an advert over here for hand held battery driven wiches. Looked pretty small and pulled 450kg.

 

Be quite the tool for outsiders if you had a few of them to do.

I was going to suggest winching, considering how easy it would be to get a rope in with no branches on the inside.

When I was working for SL Treecare.  Steve had one of them chainsaw winches fitted to an old 044 saw.  
 

Pretty capable machine and we pulled some pretty heavy learners back into the woodlands around Brands Hatch and West Kingstown and local villages.  The job was for the cycling road races for the London Olympics.

 

The trees had to be gone for the helicopter tv coverage.

 

It was one of these.
