A debarking chain having bent links; the bent links being bent either right or left, from end to end at a bend angle of from about 5 to about 90 degrees to provide a flail type debarking chain having protruding edges or corners that increase the efficiency in which bark is removed from logs during debarking operations. Bent link chains include right bent links that are bent to the right proximate the middle of the link, where the weld is preferably located, when the link is viewed from the side with the weld on the far side and left bent links that are bent to the left proximate the middle of the link, where the weld is preferably located, when the link is viewed from the side with the weld on the far side. Disclosed inventions also include a debarking drum having a plurality of debarking chains having at least two bent links, as well as debarking devices having such a debarking drum and methods of making and using the same. The debarking device preferably includes a chipping device and methods of using the same in conjunction with using such bent link debarking chain.

A device for allowing work to be carried out on or about an object includes at least one gripping arrangement. The at least one gripping arrangement is configured to grip and traverse the object so as to reach a desired location on the object and to anchor the device thereto for allowing the work to be carried out.

A heavy duty brush cutter includes a chassis, an engine, left and right cutting decks with rotating mower blades, transmissions, and a gear box. The cutter features telescoping drive shafts, hydraulic actuators for deck adjustment, a forward frame with axles for wheels or tracks, and steering arms for directional control. Additional configurations may include a telescoping tree limb cutter with a rotatable boom, counter-weights for balance, wheels or tracks on various axles, and a central rotating blade. The system is designed for robust vegetation management with various attachments for enhanced functionality.

A sensor mount for use with a timber-working device includes a monolithic structure having a base portion configured to be secured to a frame of a timber-working device, and a sensor mounting portion including a cavity configured to receive a contactless sensor. The cavity has a sensor mounting surface for securing the contactless sensor thereto.

An automated tree cutting assembly includes a collar that may be positioned around a tree. A plurality of climbing units is movably coupled to the collar. The climbing units frictionally engage the tree thereby facilitating each of the climbing units to urge the collar around and up the tree. Each of the climbing units is positionable at selected angle with respect to the collar. Thus, each of the climbing unit units may urge the collar to travel in a spiral along the tree thereby facilitating the collar to climb upwardly and downwardly along the tree. A cutting unit is movably coupled to the collar to cut branches from the tree when the collar is positioned around the tree.

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 saw bar clamping mechanism, length measuring mechanism, system for measuring the length of a tree stem, feed roller mechanism, pin retention mechanism, and a tree processor attachment comprising at least one of the mechanisms and/or system is provided. The saw bar mechanism simultaneously unclamps a saw bar and releases a saw chain for convenient removal. The length measuring mechanism comprises a measuring wheel operable to extend and retract perpendicularly to a tree stem. The feed roller mechanism includes first-side and second-side rollers, and a bearing having outer and inner sides, the bearing being rotatably coupled at its outer side to the first-side roller and rotatably coupled at its inner side to the second-side roller, the bearing making angular contact. The pin retention mechanism includes a two-part collar fitting into a groove with interference for locking a nut received by the collar.

A fluid delivery assembly is operably coupled with a reciprocating saw having a saw blade to deliver a treatment fluid to a cut portion of vegetation as the vegetation is cut. A syringe contains the treatment fluid and a fluid delivery tube has a reservoir end in fluid communication with the syringe and a delivery end adjacent the cut portion of the vegetation. A carrier is contains a portion of the fluid delivery assembly and a harness attached to the carrier has at least one strap for an operator to carry the carrier during operation of the reciprocating saw. A stepper motor is operably coupled to a PCB for storing operating parameters and for executing the operating parameters to induce advancing movement of a plunger relative to the syringe. The operating parameters are provided to the PCB by an external computing device and the PCB and stepper motor receive electrical power through an electrical power and logic cable from a power supply of the reciprocating saw. The fluid delivery tube is provided with a check valve at the reservoir end and the delivery end to retain the treatment fluid within the fluid delivery tube.
