An improved landscaping trimmer is provided. The device includes a housing having an open lower end. A motor is disposed within the housing and is operably connected to a plurality of cutting heads extending through the open lower end. The plurality of cutting heads are disposed in an offset pattern defining an upper portion of the housing and a lower portion of the housing. Each of the plurality of cutting heads is affixed to the housing in a floating arrangement. A plurality of blades extends from each of the plurality of cutting heads, whereupon actuation of the motor, the plurality of cutting heads rotate about the longitudinal axis. A handle extends from the housing, wherein the handle includes a control that activates the motor. A plurality of wheels is affixed to the housing, wherein each wheel is disposed adjacent to one cutting head of the plurality of cutting heads.

A grass mowing machine includes a vehicle body frame, a mower deck incorporating a rotary cutter blade, a coupling mechanism for coupling the mower deck to the vehicle body frame with allowing a lateral displacement of the mower deck in a vehicle body transverse direction, a mower electric motor attached to the mower deck and configured to feed rotary power to the rotary cutter blade and a displacement operation mechanism MV for laterally displacing the mower deck in the vehicle body transverse direction in operative association with the coupling mechanism.

A device for trimming around stationary objects is disclosed as a rotary mowing attachment with a cutting head assembly slidably coupled to a carrier assembly that is positioned by a slope control circuit and controller. The cutting head assembly has at least two counter-rotating blades, at least one rotator motor configured to rotate the cutting head assembly about a cutting head central axis, at least one blade drive motor configured to drive the at least two counter-rotating blades, and at least one lateral motion drive motor configured to move the cutting head assembly position relative to the carrier assembly.

An autonomous lawn mower includes a movable cover covering a traveling frame and holding devices holding the movable cover. Each holding device includes a holding shaft and a shaft holding unit. The holding shaft includes a lower half portion and an upper half portion. The shaft holding unit holds the lower half portion accommodated in an accommodating portion of the traveling frame such that the lower half portion can slide in only a horizontal direction. The upper half portion extends through a through hole of the movable cover by extending upward from the traveling frame, thereby holding the movable cover so that the movable cover is vertically displaceable. A coil spring intervenes between a receiving portion and an upper wall of the movable cover. One holding device includes a detector which detects the slide displacement amount of the lower half portion.

A method and device for trimming around stationary objects is disclosed as a rotary mowing attachment with a cutting head assembly slidably coupled to a carrier assembly that is positioned by a slope control circuit and controller. The cutting head assembly has at least two counter-rotating blades, at least one rotator motor configured to rotate the cutting head assembly about a cutting head central axis, at least one blade drive motor configured to drive the at least two counter-rotating blades, and at least one lateral motion drive motor configured to move the cutting head assembly position relative to the carrier assembly.

A radio-controlled mower with a frame (2), a motor unit (4), rolling bodies (3) configured to move said frame (2) on an area of ground (T), a central cutting unit (5), and one or more side cutting units (6; 6A, 6B); wherein said frame (2) and each side cutting unit (6; 6A; 6B) are mutually movable.

A strand trimmer and method of use thereof. The strand trimmer includes a pair of pivotable arms each having a motor, a follower wheel, and a cutter-spindle assembly disposed thereon. The arms are biased toward one another and are guided by the follower wheels to pivot around obstacles passing between the arms. The motor rotates the cutter-spindle assembly to move cutting strands extending therefrom through a cutting path with sufficient rotational velocity to cut vegetation. The cutter-spindle assembly includes a spool and a strand-feed mechanism. The spool is oriented to rotate about a horizontal axis. The strand-feed mechanism includes a solenoid actuated plunger within a shaft of the cutter-spindle assembly. The plunger engages the spool to control rotation of the spool and thereby feeding out of incremental lengths of the strand.

There is provided herein an apparatus and method for roadside asset tracking and maintenance monitoring having a mobile unit with data capture devices for capturing roadside asset imagery, global positioning system (GPS) receivers and data interfaces for communicating with an asset management server. As such, the apparatus may take roadside imagery for automated asset identification which may include utilising an asset type image recognition technique for automating the identification of the roadside assets.

Vegetation cutting apparatuses may include a wheeled apparatus frame. A cutting assembly may be carried by the wheeled apparatus frame. The cutting assembly may include an elongated chain support member having a chain support member edge. A cutting chain may be configured to traverse the chain support member edge of the chain support member. An engine may drivingly engage the cutting chain.

A method and device for trimming around stationary objects is disclosed as a rotary mowing attachment with a cutting head assembly slidably coupled to a carrier assembly that is positioned by a slope control circuit and controller. The cutting head assembly has at least two counter-rotating blades, at least one rotator motor configured to rotate the cutting head assembly about a cutting head central axis, at least one blade drive motor configured to drive the at least two counter-rotating blades, and at least one lateral motion drive motor configured to move the cutting head assembly position relative to the carrier assembly.
