An apparatus for cutting and/or handling material to be cut, in particular trees, having a pivotable boom arm to which a gripping or cutting head is attached. The boom arm includes a rotatable crane pillar, a first boom pivotably mounted on the rotatable crane pillar about a first pivot axis, a second boom pivotably mounted on the first boom about a second pivot axis. The gripping or cutting head is pivotably mounted on the second boom about a third pivot axis, and a controllable pivoting device is provided, by which the gripping or cutting head can be pivoted about the third pivot axis from a folded-out working position, in which the gripping or cutting head is mounted in front of the second boom, into a folded-in storage position, in which the gripping or cutting head is arranged to the side of the second boom.

A working machine includes a machine body, a working device provided on the machine body, an attachment provided on the working device to hold an elongated to-be-held object, a first sensor to recognize a position of one end portion of the to-be-held object, a setter to set a holding position based on a recognition result from the first sensor, the holding position being a position at which the to-be-held object is to be held by the attachment, a controller configured or programmed to control the working device. The controller is configured or programmed to control the working device to allow the attachment to hold the to-be-held object at the holding position set by the setter.

A working machine includes a machine body, a working device provided on the machine body to attach thereto an attachment to hold a to-be-held object, and a controller configured or programmed to impose an operational limitation to limit one or both of an operational area and an operational speed of the working machine when causing the attachment to perform an operation of holding the to-be-held object.

A powered handler for handling a workpiece, comprising a body extending between a first and a second end, an input device adjacent the first end, a handling implement adjacent the second end, the handling implement operatively connected to the input device and operable to handle the workpiece, and a suspender having a proximate end mounted to the body at at least one pivot of the suspender defining a pitch axis of the powered handler, the body pivotable relative to the suspender about the pitch axis, the at least one pivot disposed between the input device and the handling implement and displaceable relative to the body to a balanced position located between a first and a second position closer to the second end than the first position, the suspender having a distal end spaced upwardly from the body for mounting the suspender to suspend the body from the suspender.
