A pruner includes a pruner body, a cutting system, an electric motor to provide driving power for the cutting system. Rotation of the electric motor in a first direction is provides a cutting action. A control system is provided for controlling the electric motor. The pruner further includes a blade stuck detection system to detect a blade stuck situation in which the cutting system is not able to reach the closed position, and the control system, as a response to detection of the blade stuck situation, is configured in a recut operation to rotate the electric motor in a second direction opposite the first direction, and then to rotate the electric motor in the first direction to actuate the cutting system towards the closed position.

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.

A cutting device includes a jaw with a first jaw member and a second jaw member, a first handle attached to the first jaw member and a second handle rotatably connected to the second jaw member at a second pivot point, a gear including a first set of teeth and a second set of teeth at a first end of the second handle. The second handle is slidably connected to the second jaw member at the second pivot point to allow the second handle and the second set of teeth to move into a disengaged position where the second set of teeth are located at a distance from the first set of teeth. To ensure that the teeth of the gear engage correctly, a slide lock is in an enabling state allowing the second handle and the second set of teeth to slide in a slide direction from the disengaged position to the engaged position only when the first set of teeth and the second set of teeth are aligned into a mutually predetermined position.

Cutting device

A tool includes a tool head with a utilization surface. The tool also includes a counter device responding to an impact applied to the utilization surface. The counter device has a memory, a microcontroller controlling operation of the counter device, an indicator, and an energizer connected to the microcontroller, which in response to the impact applied to the utilization surface, produces an electric current energizing the counter device to make a modification in the memory and provide information about the cumulative count of impacts in the memory via the indicator to a user.
