What is the purpose of using a pole saw?

The purpose of using a pole saw is primarily to prune or cut branches that are out of reach without needing a ladder. This tool extends the reach of the user, allowing them to safely trim or cut overhead branches from a distance, which is crucial for maintaining tree health, safety, and aesthetics. By utilizing a pole saw, a tree trimmer can avoid the risks associated with climbing or using a ladder, reducing the likelihood of accidents and injuries.

Other options don't align with the primary function of a pole saw. For example, while removing leaves from the ground may be part of landscape maintenance, it does not require a pole saw. Measuring the height of a tree does not involve cutting and is typically done using different tools or methods. Cutting down small trees might be accomplished with a saw, but a pole saw is designed specifically for pruning and cutting branches rather than felling trees entirely.
