A timber-working head is configured to hold a felled tree and to feed the felled tree. The timber-working head comprises a frame and a delimb knife module mounted to the frame and configured to delimb the felled tree when the felled tree is fed past the delimb knife module. The delimb knife module has a central blade, a pivotable first side blade, and a pivotable second side blade.

A timber-working device having a first pivoting drive arm and a second pivoting drive arm, and a timing link for connecting them. The timing link includes an elongate member having a first end and a second end. A first aperture is at the first end and a second aperture at the second end. At least one of the first aperture and the second aperture is elongate along the length of the member.

A remote-operated palm tree trimming system and apparatus, configured to ascend a palm tree safely via treaded tires and trim the tree via at least one saw blade. The tires are disposed in communication with actuators which apply pressure against the trunk of the tree, ensuring that the tires maintain adequate grip to overcome gravity during ascent. A remote control, operated by user on the ground, enables control of the wheels, actuators, and saw blade, facilitating manipulation of the device to effectively trim the tree remotely, ensuring the safety of the operator.

A processing head (10) for a forestry machine (1) is intended to process a tree (9) having a trunk (92) with a longitudinal direction (90), branches (94) extending from the trunk (92) transversely to the longitudinal direction (90) and knots (96) extending into the trunk (92). The processing head (10) comprises: a frame (2) having a seat (20) for receiving the trunk (92) of the tree (9) to be processed; a motorised device for moving the trunk (92) relative to the seat (20), by advancing the trunk (92) through the seat (20) along the longitudinal direction (90) of the trunk (92); one or more blades (26) for cutting the branches (94) from the trunk (92) as the trunk (92) advances; a detection system for detecting positions of the branches (94) and/or of the knots (96) on the trunk (92) as the trunk (92) advances. Information on the positions of the branches (94) and/or of the knots (96) is processed to determine an identification code that is based on said positions and that refers to said trunk (92) or to a segment obtained from said trunk (92). The identification code is comparable against a code determined a posteriori for a specific trunk or for a specific segment of trunk, in order to establish whether the specific trunk or the specific segment of trunk corresponds to said trunk (92) or to said segment of trunk (92). The information on the positions of branches (94) and/or of knots (96) can also be used to determine, during a processing of the tree (9), one or more positions on the trunk (92) in which to cut the trunk (92) perpendicularly or transversely to the longitudinal direction (90), which is to say to optimise the truncation of the trunk (92).

The present invention provides an apparatus for self-aligning pruning of trees. The apparatus includes a frame and a cutting tool that is attached to the frame. A power supply is connected to the cutting tool and there is a means for controlling the power supply. A support apparatus such as an Unmanned Aerial Vehicle is attached to the frame. The support apparatus can be controlled remotely such that it can position the frame horizontally and vertically. The frame includes at least one guide leg that is angled down and away from the cutting tool and the frame is connected to the support apparatus such that the frame can rotate relative to the support structure in the horizontal plane.

An airborne grapple saw system includes a suspension assembly, a hydraulic power pack assembly, and a grapple saw head assembly. The suspension assembly is configured to be suspended from an aerial vehicle. The hydraulic power pack assembly is operatively coupled with the suspension assembly. The grapple saw head assembly is operatively coupled with the hydraulic power pack assembly. The grapple saw head assembly is configured to freely rotate about a vertical axis an unlimited number of revolutions. The grapple saw head assembly includes a saw and first and second grapple arms. The grapple arms are pivotable between an open configuration, where the grapple arms are configured to obtain and release the vegetation, and a closed configuration, where the grapple arms are configured to securely retain the vegetation.
