Tree loppers are used for cutting back branches on trees and shrubs. They are best used on branches that are not large enough to need a saw but are too thick to be cut with shears. There are two main types of tree lopper, with two types of cutting mechanisms.
Bypass loppers have the same kind of action as scissors. A sharp blade cuts against a blunt blade, but bypasses it, hence the name. This produces a very sharp and accurate cut. This type of lopper is best used on living plants and is ideal if you are trying to grow a tree or shrub into a particular shape. It is possible to use the lopper on dead material, but this could damage the blade or result in dead wood stuck between the blades.
Anvil loppers by contrast are used on dead branches. Here the sharp cutting blade cuts against a flat anvil, making a much rougher cut. They are useful for removing dead wood from a tree, or for shortening a branch before cutting it more carefully with a bypass lopper. Using them to make a final cut on a live plant could damage it, as it makes it easier for disease or infection to enter.
Both types of lopper can have a ratcheted or geared cutting action. The advantage of a ratcheted lopper is that the blades will stay in position when you open the handles, which means you can then increase the cutting force without having to apply extra pressure. This is very useful if you are trying to cut thick branches, or if you lack the strength to squeeze the handles fully.
A geared cutting action can also be used with both types of lopper. Like a ratcheted lopper, a geared lopper will also amplify the force and allow you to make large cuts. However, the blades will not stay in place if you open the handles, which can make them harder to use. You also need more space to use them in, as the handles will need to be fully open when you start to cut.
If you are in any doubt as to which type of lopper to use, just call a professional tree service. They will be able to prune and cut back your trees and shrubs to the required size, using the right tools for the job and ensuring that any remaining plants are cut cleanly so as to limit the risk of disease.
