If you have a leaning tree or a 'leaner' for short, you will need to use rope and wedges to gain a mechanical advantage to push/pull the tree where you want and away from structures. This makes the project several degrees more dangerous so watch this video to understand the physics involved. It's not the most exciting video but this is one area where safety and understanding precedes entertainment.
