An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the up-and-down direction (V) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to engine vibration to which the safety device should not be sensitive so much.

An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the right-and-left direction (R-L) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to impulses in the direction parallel to a moving direction of a cutting blade (40) operated by an operator at work.

A garden tool includes a connecting rod assembly, a working head, a power source, a first rod connected to the working head, a second rod connected to the power source, and a connection structure for mechanical and electrical connection between the first and second rods. A first terminal is arranged on the first rod and a second terminal arranged on the second rod, the first terminal being connected to a first wire, the second terminal being connected to a second wire, the first terminal and the second terminal connectable to transmit power of the power source to the working head through the first wire and the second wire. A second base is mounted in the second rod, the second base including at least two jacks independent of each other. At least two second terminals are respectively mounted in respective jacks.

Lock off assemblies for trimmers are provided. A trimmer includes a working head; a handle assembly connected to the working head by a connecting member; a trigger connected to the handle assembly and movable between an off position and an on position, wherein the trigger being in the on position causes actuation of the working head; and a lock off assembly. The lock off assembly includes a switch connected to the handle assembly and movable between a safe position and an operate position; and a pivotable extension pivotably connected to the switch, wherein the pivotable extension contacts and blocks the trigger when the switch is in the safe position and the trigger is moved from the off position towards the on position, and wherein the trigger is free to move between the off position and the on position when the switch is in the operate position.

A string trimmer equipped with a knife and deflector apparatus mounted on the shroud directs cut debris laterally away from a workperson operating the string trimmer. A knife cutting edge located below the shroud cuts vegetation moved by the revolving string into cut debris. An upwardly extended radial deflector mounted on the shroud directs the cut debris laterally away from the shroud and workperson.

A guard assembly for a trimmer tool including a tool head, the guard assembly including a mount body forming a slot extending along a radial direction and including an attachment member; a guard body forming a perimeter configured to partially surround the tool head, the guard body forming a first opening configured to align with the slot at the mount body, the guard body forming a second opening from which a track extends along the radial direction, wherein the attachment member is extendable into the second opening and into the track, the attachment member of the mount body configured to slide within the track at the guard body; and a handle assembly extendable through the slot at the mount body and the first opening at the guard body to selectively affix the mount body to the guard body.
