  • 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: 9027330
    Abstract: A catalytic muffler for an internal combustion engine of a portable working tool, e.g. a chain saw or a trimmer, having a housing designed to be directly attached to an exhaust port of an engine. The housing further includes a front chamber and a rear chamber divided from each other by an intermediate baffle. The housing further having an inner housing having a first open end constituting the exhaust gas inlet located in the rear chamber. The inner housing includes a catalyst body through which essentially all exhaust gas flows when in use. A second open end of the inner housing is arranged in one of said front and rear chambers and the exhaust gas outlet of the muffler is arranged in the other chamber such that treated gas in use flows through at least one aperture in the intermediate baffle from one chamber to the other.

  • Patent number: 8984718
    Abstract: A handle height adjustment device of a handle assembly (2) of a walk-behind power tool (1). The handle height adjustment device (100) comprises a first toothed disk member (200), a second toothed disk member (300), and a disk interconnecting member. The disk interconnecting member (400) is arranged to be connected to the first toothed disk member (200) by means of a first interconnection mechanism (401), which first interconnection mechanism (401) inhibits relative movement between the disk interconnecting member (400) and the first toothed disk member (200) along an axis of rotation (500) of the handle height adjustment device (100), and which first interconnection mechanism (401) allows the disk interconnecting member to rotate relative the first toothed disk member about the axis of rotation (500). The disk interconnecting member (400) is arranged to be threadably connected to the second toothed disk member (300) by means of a second interconnection mechanism (402).
