The present disclosure concerns a saw tooth holder for a cutting disk of a rotary cutting machine. The saw tooth holder comprises a holder body having a tooth-receiving surface abuttable against a rear surface of a saw tooth of a tooth assembly and a trailing surface, opposed to the tooth-receiving surface, and defining a trailing oblique angle with respect to the tooth-receiving surface. The holder body has a fastener-receiving aperture extending therethrough between the tooth-receiving surface and the trailing surface and being accessible from the tooth-receiving surface and the trailing surface. The present disclosure also concerns a cutting disk comprising such a saw tooth holder, a saw tooth holder in combination with a tooth assembly, and a rotary cutting machine comprising such a cutting disk.

In accordance with an example embodiment, an attachment for a work vehicle includes a hydraulic motor including a case cavity, a bearing, a mandrel received by the bearing, and a disc saw rotationally coupled to the hydraulic motor via the mandrel. A mandrel cavity surrounds the mandrel, and at least a portion of the bearing is disposed within the mandrel cavity. The mandrel cavity is hydraulically connected to the case cavity downstream of the case cavity.

An insulating felling grapple is used with an insulating utility vehicle. The utility worker stands on the ground near the worksite and remotely controls the insulating felling grapple and the utility vehicle to perform the task. In addition to other standard trimming and removal tasks, the insulating felling grapple is adapted to allow for the removal of energized vegetation material. In one method, the utility worker grasps the energized vegetation material, lifts or moves the energized vegetation material such that it is no longer energized, severs the non-energized vegetation material, and moves the severed vegetation material to a discard location. A boom assembly of the utility vehicle includes a primary insulation segment. The felling grapple includes a secondary insulation segment, as well as a grapple and a feller. The grapple has at least two tines for gripping the energized material. The feller is configured to sever the energized or nonenergized material.

A field-configurable apparatus for different aerial applications is provided. The field-configurable apparatus attaches to an aerial boom on a mobile carrier. The apparatus can perform rapid semi-precise cutting of vegetation. Additionally, the apparatus can perform more precise trimming of one or more areas (e.g., limbs) and optionally use a limb clamp to prevent cut limbs/vegetation from arbitrarily falling on objects below the cutting area. Still further, the apparatus can have a grapple or similar device attached to the end of the boom for use in relocating debris or for loading debris. Other industrial applications are also possible (e.g., commercial water blasting, deicing of planes, etc.). In each configuration, the apparatus comprises one or more rotatable or pivoting couplings to allow for rotation about one or more axis and therefore allow precise manipulation of an aerial tool assembly from an operator in the vehicle or on the ground.
