How to cut down a leaning tree is not an easy question to answer. The reason for this is that trees are living things and as such have a tendency to lean over time. In fact, if you had a leaning tree fall on its side and was left there, it would take decades for it to recuperate itself. So the best way of dealing with this issue is to try and prevent it in the first place.
Before we go any further on how to cut down a leaning tree, let us first examine what exactly a tree leans upon. Tree roots are the ones that hold the tree up; these roots are why the tree rests on the ground. When a tree is growing, there are tendrils on the top that actually extend to the floor and these are what the tree uses as a form of support. When a tree is growing, its main tendency is to keep itself upright and as such if there is any sort of blockage on one of these tendrils, the tree can lean over. It all depends on the direction of gravity and the type of tree.
If the supporting tendrils get to be weak or even removed, the tree can lean over and break free of the support system. You can see this by simply looking at the crown of a tree. The most common type of tree tends to lean to the left or the right depending on which way the wind blows. If you were to walk up to a tree leaning tree, you could clearly see the weak branches sticking out and the support system having been taken away. The weak parts of the support system can then become the places where the tree starts to lean over.
So how do you prevent this from happening? To prevent the tree from leaning over, the best thing you can do is remove or cut away any of the weak or dangerous branches on the tree. Make sure you also clear away any overhanging limbs. Another thing you can do is put in a support system to the tree to strengthen it so it can still hold the weight of the extra weight the extra branches are putting on top of it. This is something that needs to be done immediately or the tree can easily break free of the support system.
In addition to removing branches, you should also check under the tree to see if it's roots are becoming tangled up in any of the tree's branches. This is one of the worst things you can do because it weakens the tree's ability to support itself. One of the first steps in learning how to cut down a leaning tree is to remove any and all overhanging limbs. You can do this easily by simply taking a screwdriver and digging out the root ball underneath the tree.
Once you have done this, you can then proceed to cutting through the thickest part of the tree. The thickest part of the tree is where the tree roots are located. This is the part of the tree where the branches are attached to the tree. To cut through the roots, you need to use a saw with an angle cutter so you can cut through the branches as well. Once you've gotten the most part of the tree removed, you can then go ahead and assess the support system of the tree and see if it will be easier for you to remove the tree after it's fallen down.
