We had a bit of a mix up on who was bringing what kit, so a bit of improvisation was required, but Tim's great at that kind of thing. We used our Tirfor 516 winch on one of the trees, in conjunction with wedges and a sledgehammer. The others came down more easily, just with chainsaw and the wedges.
Here's the video of it all. You'll see I had to make a fairly sharp exit after operating the winch, although once the tree was down I saw I could have remained where I was, but it's not the kind of risk you take!
Here's a few still pictures to go with it:
As you can see, they were pretty big trees, and we need to go back later to finish clearing them up. They had rotten parts at their centres, so it was definitely good to get them down, given the proximity to the barn. We'll probably get several cubic metres of logs out of them, so they'll be put to good use.
