Abstract
A tree pruner includes a pruner body, a blade system, and an electric motor to provide driving power for the blade system. Rotation of the electric motor in a first direction provides a cutting action. A control system controls the electric motor, and a transmission system having a transmission rope transfers power from the electric motor to the blade system. The tree pruner includes a tension management system to detect a slack rope situation in which tension of the transmission rope is below a predetermined limit value, and the control system prevents rotation of the electric motor in a second direction opposite to the first direction as a response to detection of the slack rope situation.
