Abstract: 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.

Abstract: An airborne vegetation trimming apparatus includes an apparatus housing, an elongated saw boom extending from the apparatus housing, a plurality of rotatable saw blades carried by the saw boom, a saw blade operating system drivingly engaging the saw blades, a rotatable tubing coupling carried by the apparatus housing and a tubing coupling rotation motor drivingly engaging the tubing coupling.
