A tree saw attachment for a modular landscape trimmer is disclosed. In one embodiment, the tree saw attachment is provided with a drive unit having a drive shaft operably connectable to a motive source and a transmission operably connected to the drive shaft. An anvil is connected to and extending from an output side of the transmission of the drive unit, and a blade is connected to the output shaft of the transmission. The blade has an arcuate outer peripheral edge with teeth formed along a portion thereof forming a cutting edge so as the output shaft is rotated, the distance between the cutting edge and a central axis of the output shaft increases until the blade has substantially completed one rotation. Rotation of the blade causes the blade to move transversely with respect to the anvil to engage and cut material positioned between the blade and the anvil.

A blade cover for an axe includes a protective portion arranged to cover a sharp edge of a tool head. The blade cover has a locking mechanism releasably attachable to the tool head, the locking mechanism includes a rotatable switch and a receiver, the rotatable switch is rotatable between two positions, so that in a first position the blade cover is fixedly securable to the tool head, and in a second position the blade cover is releasably attachable to the tool head. An axe assembly is also provided and includes an axe having a tool head and a handle, where the tool head includes a through hole, and the blade cover.

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 system for prioritizing trim requests can include an image processor that identifies a location associated with a customer trim request that includes an image of vegetation and industrial equipment and marks the vegetation and the industrial equipment visible in the image associated with the customer trim request. The system can also include a vegetation maintenance analyzer that searches for a match between the identified location associated with the customer trim request with a location associated with one of a past executed service ticket and a pending service ticket. The maintenance analyzer generates a maintenance profile for the customer trim request based on the results of the search and data in the customer trim request. The system can further include a priority engine that assigns priority to the customer trim request based on the maintenance profile for the customer trim request.

The first embodiment of the tool for girdling the trunk of a tree includes an elongated and horizontally disposed handle having first and second ends. The tool also includes a horizontally disposed cutting blade support having a first elongated arm portion and a curved arm portion. The first elongated arm portion is pivotally connected to the handle intermediate the lengths thereof. A linkage also pivotally connects the second end of the handle to the first end of the first elongated arm portion. A cutting blade carriage is selectively movably secured to the curved arm portion to compensate for various tree trunk diameters. A second embodiment of the tool includes an elongated handle which is adjustably secured to a cutting blade support which has a cutting blade secured thereto which is forced into engagement with the tree trunk by a spring arm.

Electric scissors (1A, 1B) is provided with: a first blade (2A, 2B); a second blade (3A, 3B); a toggle link mechanism (7A, 7B) including a first link (71A, 71B), a second link (72A, 72B), and a drive shaft (70A, 70B); and a drive section (5, 6). One end of the first link (71A, 71B) is rotatably connected to a transmission portion (21A, 21B) of the first blade (2A, 2B). One end of the second link (72A, 72B) is rotatably connected to a transmission portion (31A, 31B) of the second blade (3A, 3B). The other end of the first link (71A, 71B) is rotatably connected to the other end of the second link (72A, 72B) through the drive shaft (70A, 70B). The drive section (5, 6) is configured to open/close the first blade (2A, 2B) and the second blade (3A, 3B) by displacing the drive shaft (70A, 70B) in a direction perpendicular to an axial direction of the drive shaft (70A, 70B).

A lopper a lopping assembly mounted to an upper end of a pole, said lopping assembly includes a movable knife and a counter knife. The movable knife is connected via a first transmission and connection assembly to an operating assembly disposed at a lower end of the pole, which is configured to move the movable knife and/or the counter knife in a direction to one another. The operating assembly includes first and second actuating elements. The first actuating element is coupled to the first transmission and connection assembly and the second actuating element is coupled via a second transmission and connection assembly and releasable latching assembly to the first actuating element. Movement of the second actuating element away from the first actuation element causes, via the second transmission and connection assembly, a movement of the first actuating element in said first direction.
