To perform your own tree lopping, you need to make sure you're not causing injury to yourself, others, or objects nearby. It's hard to be completely safe while performing tree lopping as you need to be positioned on a ladder or in the tree, which increases the risk for injuring yourself because of falling. If you want to remove this risk from the procedure of tree lopping, there are a few tools you can use where you can remain on the ground while still cutting branches from high up on the tree.
A rope saw is a versatile tool that can be used to cut any size of branch, but it mainly works on larger branches as the saw is flexible and might be hard to wrap around smaller branches. This type of tool requires that you have a helper with you to help you saw. This way, you can hold one rope each and thus keep away from the dangerous area directly under the branch where you're in danger of having it fall on you. For especially large branches, you might need someone to tie a rope around the branch and toss it over another large branch in order to hoist it down towards the ground slowly and safely.
For smaller branches, you might not need more than a pole lopper. This type of saw can also be used on larger branches depending on the size of the blade, but can be dangerous to use as you won't be able to steer entirely clear of the area where the branch is going to fall. The rope method with hoisting it down to the ground can be used also here, but large branches still pose a threat to your safety. You should also be weary of pole loppers with telescope handles. If it were to unfold unexpectedly, you could hurt yourself. Secure the sections of the telescope pole with tape to make sure it stays up while you're using it.
A last tool you can use for tree lopping from the ground is a folding pruner or lopper. These types of tools are very light and easy to handle, and can be attached to a pole to reach higher up. However, these have the same disadvantages as pole loppers, with the difference that a folding lopper might unfold while you're working, which might not be dangerous if it happens when it's hoisted, but frustrating as it takes more time from your work to sort it out.
