The present invention provides an improved, autonomous unmanned aircraft vehicle (UAV) for harvesting or diluting fruit, and a control unit for coordinating flight and/or harvesting missions thereof, as well as a system and method for harvesting fruits.

A robotic pruning apparatus that can be adapted to fit around a variety of trees and can move along the length of the tree while performing a variety of pruning operations. The pruning apparatus can be configured with a variety of different cutting heads that have multiple degrees of freedom of movement such that they can be used to perform any number of cutting operations along the length of the tree. The apparatus can be remotely operated by a human or can be autonomous or semi-autonomous.

An aerial vegetation trimming system. The aerial vegetation trimming system may include a saw assembly, wherein the saw assembly may include a plurality of saw blades disposed along a length of a beam. The aerial vegetation trimming system may further include an electric motor operatively connected to the saw assembly, wherein the electric motor is configured to drive the plurality of saw blades; and at least one boom disposed between the electric motor and a vehicle, wherein the at least one boom is configured to connect the saw assembly to the vehicle.

A system for a hydraulic tree branch shear including a skid-steer loader and a shear assembly. The skid-steer loader of the system for a hydraulic tree branch shear may be an existing skid-steer loader adapter to have the shear assembly attached thereon. The shear assembly is powered by a hydraulic attachment that is configured to be powered from the skid-steer loader. Additionally, the controls for the shear assembly are configured to be attached to the existing controls of the skid-steer loader. The shear assembly is mounted to the skid-steer loader and allows a user to cut down hard to reach tree branches from the comfort of the skid-steer loader. Furthermore, the use of the skid steer loader provides a user protection from having tree branches falling on the user's head.

A tree and shrub cutting and trimming device having multiple robotic arms FIG. 2B and M for gross and fine movements, a wheeled movable base FIG. 3 and an electric cutting or trimming tool. This device allows the operator to be on the ground level, a substantial distance from the cutting surface and will not be holding the cutting or trimming device FIG. 6. This device drastically reduces insurance costs and labor cost, thus a less expensive much safer device to perform these tasks is provided in this field of endeavor.

Disclosed herein is a power tool that includes a direct current power source, motor, and motor controller. In some embodiments, the power source comprises a battery pack configured to supply current at a nominal voltage in excess of 100 VDC. Embodiments of the tool are configured to operate at a high power at least comparable to tools operating at lower voltages, and to produce noise levels in operation that are less than 65 decibels.

A hand-guided motorized working apparatus and an operating device for the apparatus are provided. The operating device has a handle shank configured to be hand-gripped, an operating element receiving region adjoining the handle shank, and an operating unit which acts on the apparatus operation and includes an operating element which is held movably on the operating element receiving region for actuation by a finger of a hand gripping the handle shank, and has a finger rest region extending along an outer side of the operating element receiving region. In the operating device, the operating element is a pivot operating lever which is held on the operating element receiving region so as to be pivotable about a pivot axis, wherein the pivot axis extends with a main direction component perpendicular to a shank longitudinal axis of the handle shank, and wherein the finger rest region, in a longitudinal extension along the outer side of the operating element receiving region, has a bent and/or angled course with a circumferential direction component and an axial direction component.

A method for attaching a removable saw blade to a reciprocating type hedge trimmer to extend the utility for cutting larger diameter stalks without requiring a second appliance. The removable nature of the blade allows replacement should the blade become dull or damaged, and also allows use of the trimmer without the blade installed with minimal impact to the base functionality of the trimmer. Such trimmer can be hand held or machine mounted and powered by a variety of power sources.

An agricultural leaf stripper which can adopt numerous configurations allowing leaf stripping of bushes and trees of varying shapes and sizes consists of a structure capable of being transported along a horizontal axis parallel to the ground and consisting of a structure formed of two parts one of which is fixed to the transporter vehicle and the other of which can slide vertically on the fixed part and supports a rectilinear rail generally parallel to the structure and able to be moved horizontally towards and away from the structure and tilted with respect thereto, the rail carrying at least two pneumatic leaf stripping heads, each stripping head being able to be set to a desired position on the rail independently of the other leaf stripping heads, and each being able to be set to a desired orientation about its working axis on the rail.

A working machine may include a pipe including: an outer pipe; an inner pipe inserted in the outer pipe; a pipe holder fixed to the outer pipe; and a stopper disposed inside the outer pipe. The pipe holder includes a wall part. The inner pipe includes a fixing hole having a longitudinal direction in a circumferential direction of an outer circumferential surface of the inner pipe. A rear surface of the fixing hole has a shape extending along a plane orthogonal to a front-rear direction. The stopper includes: an abutting part that abuts the wall part from behind when the inner pipe extends to a maximum length relative to the outer pipe; and a protruding part configured to fit in the fixing hole of the inner pipe. A rear surface of the protruding part has a shape extending along a plane parallel to the rear surface of the fixing hole.
