Hit it with an axe or sledge hammer first while being ready to run to make sure some of those limbs aren’t ready to turn loose. After that, notch it, send it 180* from the blind if you are really worried about it. Start your back cut 2-3” above the notch and let it fall. Put a wedge in and push or pull it with the tractor if you are really worried. Main thing is to make sure the limbs or top aren’t going to fall to start with.
