  • Patent number: 10470363
    Abstract: A height adjustment arrangement (1) for a lawn mower (20) for changing a cutting height is provided. The height adjustment arrangement comprises a respective link arm (2a, 2b) pivotally arranged at opposite sides of the chassis (21), and a transversal rod (5) extending between the link arms (2a, 2b) comprising wheel attachment ends (6a, 6b) configured to protrude outwardly from the respective link arm (2a, 2b). The height adjustment arrangement further comprises a locking arrangement (11) for releaseably locking at least one of the link arms (2a, 2b) in a pivot position. The transversal rod comprises connection portions (9a, 9b) which are essentially parallel to the link arms and releasably connected thereto such that pivoting of the link arm (2a, 2b) causes the wheel attachment ends (6a, 6b) to synchronously change the cutting height of the lawn mower chassis (21).

  • Patent number: 9491907
    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 body, 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.

  • Patent number: 9078395
    Abstract: A folding arrangement of a walk-behind power tool includes a hinge having a first hinge part and a second hinge part pivotally interconnected about a hinge axis, so as to enable pivoting of the hinge between a folded position and a closed position. The first hinge part has a first opening for passing through a cable harness. The second hinge part has a second opening for receiving the cable harness. The first and second openings are facing each other when the hinge is in the closed position. At least one of the first and second hinge parts has a protruding portion for directing the cable harness towards the first and second opening when the hinge pivots from the folded position to the closed position.

  • Publication number: 20150150192
    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).

  • Patent number: 8844253
    Abstract: A front baffle assembly (1) for a lawn mower (30) is provided. The front baffle assembly (1) is adapted for attachment to a lawn mower chassis (2), and comprises a stopper (5a, 5b) configured to abut against an upper side of the chassis (2) and a front baffle (4) configured to abut against a lower side of the chassis (2). The front baffle assembly (1) comprises a catch element (6a, 6b) which protrudes downwardly from the stopper (5a, 5b) and is arranged to extend through the chassis (2) and beyond a lower side of the front baffle (4). The front baffle assembly (1) comprises a front axle (7) arranged to be received between the catch element (6a, 6b) and the lower side of the front baffle (4) to clamp the chassis (2) between the stopper (5a, 5b) and the front baffle (4).
