I've been cutting all sorts of trees, softwood, hardwood, dead and alive in UK and Aus for forty years and the only way to go with what you are talking about, without pics to see better, is as Pat B and El Destructo suggest. You need all the gear, all the equipment and a lot of experience. If you don't have that, my advise is simple: DON'T DO IT. A hundred grand repair to a house, or people injured or dead is NOT worth the risk. Please don't take the chance. 2 tonne is too much to play with and even a small tree can break a limb, blind, trap. I know what I am doing and with winches, top-limbing etc. I have seen a gust of wind come from nowhere and turn a leafless tree on its base and drop it 180 degrees from where it was aimed, snapping 10 ton steel cables as it went, seen a new rope snap and drop a 6 inch by 6 foot branch through a car engine block and many, many minor mishaps. I have seen a trunk explode for no apparent reason into splinters and shrapnel as it was cut and a thirty years experienced limb-lopper slip, cut through his safety ropes and fall, very luckily into a soft pig yard full of crap. He also cut through new teflon trousers and badly ripped into his shin. Chain saws are lethal, trees are unpredictable, fate is chancy and an experienced tree feller will weigh it all up and charge you a couple of hundred while you have a beer and watch a DVD.
