Abstract: The present invention discloses a folding arrangement (122) of a walk-behind power tool (100). The folding arrangement (122) includes a hinge (202) having a first hinge part (204) and a second hinge part (206). The first hinge part (204) is arranged for receiving an end of a first elongate member (118), while the second hinge part (206) is arranged for receiving an end of a second elongate member (120). Further, the first (204) and second (206) hinge parts are pivotally interconnected about a hinge axis (A), so as to enable pivoting of the hinge between a folded position and a closed position. Moreover, the first hinge part (204) has a first opening (212) arranged for passing through a cable harness (121) arriving from a channel or groove provided in the first elongate member (118). Similarly, the second hinge part (206) has a second opening (216) arranged for receiving the cable harness (121) arriving from the first opening (212). The first and second openings (212, 216) are facing each other when the hinge (202) is in the closed position. Moreover, at least one of the first (204) and second (206) hinge parts has a protruding portion (220), arranged for directing the cable harness (121) towards the first (212) and second openings (216) when the hinge (202) pivots from the folded position to the closed position. The application also concerns a handle assembly and a walk-behind power tool comprising such an arrangement.

Abstract: A walk-behind lawn mower comprising a body with an engine driving a cutting blade, and a handle assembly which is pivotably connected to the body. The lawn mower furthermore comprises a handle control arrangement for controlling pivotal movement of the handle assembly relative to the bod, between a working position and a pivoted position. The handle control arrangement comprises a locking member, selectively displaceable between an open state in which the locking member allows pivotal movement of the handle assembly from the working position to the pivoted position, and a locked state in which the locking member inhibits pivotal movement of the handle assembly from the working position to the pivoted position. The handle control arrangement also comprises an actuating member operatively connected to the locking member and controlling the state of the locking member. The actuating member is also arranged to control activation and deactivation of a device arranged to inhibit rotation of the cutting blade of the walk- behind lawn mower.
