A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths. The saws are adjusted in response to the computer solution and the log is positioned by a positioner according to a computer generated reference datum. This results in the log being positioned for cutting to the optimum random lengths. A command signal is sent from the computer to the log sorting system, which tracks the position of the random lengths and allows them to be sorted to the appropriate sort storage bin.

The invention relates to a barking device comprising a barking arm (1) and a barking tool (2) which is mountable in a tool seat of the barking arm. The barking tool comprises a convex mounting surface (13), while the seat surface (7) of the barking arm is concave. The barking tool is, with the aid of a connecting means, mountable in the tool seat and displaceable by rotating displacement. The connecting means comprises a screw (18) and a sleeve-like nut (21). The head (20, 23) of one of the connecting means parts (18, 21) is designed to prevent displacement and rotation.

An apparatus for removing obstructions caused by both high and low lying vegetation, the apparatus including a conventional industrial type vehicle, such as a tractor or backhoe loader, a swing frame swingably connected about a substantially vertical axis on the vehicle, an arm, such as backhoe boom, pivotally connected about a substantially horizontal axis on the swing frame, a telescoping boom connected with the arm, means of detachably connecting the telescoping boom with the arm and cutting means mounted about a first end of the telescoping boom. The apparatus is supported, powered and controlled using the standard attachments, power systems and controls of a conventional industrial-type vehicle.

“A tree trimming device that automatically climbs a tree or other vertical member and shears limbs or debris as it climbs has an anchor structure with substantially horizontal clamps, a cutting assembly with substantially horizontal clamps, vertical connecting pistons, and a cutting blade assembly.”

A pruning assembly (10) including an elongate supporting body (not shown), right (11) and left (12) jaw members hinged together and movable along the supporting body and each having three sets of blade members (31) mounted on actuator means (16) and alternatively displaced above and below a plane to form two staggered rows of three bores each, the actuator means (16) adapted to maintain the clearance between the trunk and each set of blade members (31).
