Which tool would be used to remove branches that cannot be reached from the ground?

The pole pruner is specifically designed for the task of removing branches that are high up and cannot be accessed from the ground. This tool typically features a long extendable pole with a cutting mechanism on the end, allowing users to reach taller branches without the need for ladders or unsafe climbing.

Loppers, while effective for cutting thicker branches, require the user to be closer to the target, which isn't suitable for high branches. A pruning saw is also more effective for cutting larger branches but, like loppers, lacks the reach provided by a pole pruner. Hand pruners are intended for small, reachable branches and are not practical for anything out of arm's reach. Therefore, the pole pruner stands out as the best option for safely handling elevated branches.
