An implement system for a machine. The implement system includes a boom, an implement, a roller assembly and a carriage. The boom has a telescopic structure and a first end. The implement is coupled to the first end of the boom. The roller assembly is configured to be coupled to the machine. The carriage is engaged with the roller assembly and is coupled to the boom. The carriage is configured to move linearly along a longitudinal axis of the machine between a first position and a second position.

Communications between heavy equipment machines during tree felling operations. A method includes identifying a tree felling area to be cut in a tree felling operation and determining instructions for executing the tree felling operation with two or more heavy equipment machinery. The method includes receiving first sensor data from a first heavy equipment during execution of the tree felling operation and providing the first sensor data to a second heavy equipment during execution of the tree felling operation.

A method for operating forestry machinery includes providing timber units with forestry machines and an operation processor. The method also includes detecting or receiving data from an information source, where the data includes worksite preparation data, navigation data, or worksite situation data. The data is processed by the operation processor and operation parameters of the forestry machine are set based on the processing of the data. The method further includes communicating instructions to the forestry machine by the operation processor, where the instructions include the operation parameters.

A power wedge device includes a base, a screw-type cone wedge mounted to the base and including a threaded cone portion that tapers to a pointed tip. A motor is mounted to the base and coupled to the screw-type cone wedge to rotatably drive the threaded cone portion. A counter-rotational member is coupled to the base and is configured to ground the screw-type cone wedge so as to prevent the screw-type cone wedge from spinning the motor and the base.

An airborne vegetation cutting assembly aerially suspended by an aircraft to simultaneously grapple and trim vegetation across a cutting plane that can be rotated and pivoted at multiple cutting angles. The assembly comprises a housing that contains the hydraulic mechanism and a power portion for operating the components. A tube extends from the aircraft to the housing. A knuckle detachably attaches the housing to the tube. Upper and lower grappling devices extend from the housing in a coplanar, spaced-apart relationship. The grappling devices grapple and release the vegetation independently of each other. A blade is coplanar with the grappling devices. The blade cuts a cross section of the vegetation along a cutting plane after the grappling devices grapple the vegetation. A connective knuckle rotates and pivots to enable rotational and pivotal control of the grappling devices and the blade, so as to change the orientation of the cutting plane.

A joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.

A feed roller assembly of a harvester head of a forestry machine includes a pivoted arm operated by a hydraulic cylinder and a feed roller and one operating device attached to the pivoted arm having an attachment hub driving the feed roller, the feed roller includes at least one attachment flange, at least two toothed discs, spacer pieces between at least the attachment flange and the toothed discs, attachment bolts connecting the attachment flange, the toothed discs, and the spacer pieces to form the feed roller as a bolted construction, and a cleaning comb attached to the arm for cleaning gaps formed between each pair of components when the feed roller is rotating.

A rotation device arrangement includes a structure and a suspension part for suspending the rotation device from a boom. The structure includes a first inner body part and first conduits for leading a pressure medium through the first inner body part. A second outer body part is arranged at least partly around the first inner body part completely rotatably. First connections are fitted for leading the pressure medium through the second outer body part. Second conduits are fitted to at least one of an outer surface belonging to the first inner body part and an inner surface belonging to the second outer body part for leading the pressure medium from the first conduit to the first connections. A bearing is arranged to permit the second outer body part to rotate and to carry loads axially and radially. Second connections attach a direct-drive pressure-medium operated turning device to the structure coaxially to transmit torque.
