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 releasably 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).

Abstract: A lawn mower wheel (2) is provided. The lawn mower wheel (2) comprises a hub (3) arranged for attachment to a lawn mower wheel axle extending in an axial direction. The lawn mower wheel (2) comprises a tread (4). The tread (4) has a tread width (8) in the axial direction. The tread is a web structure of material portions (6) separated by through openings (7) to reduce the area of the tread (4) onto which grass clippings may attach. The lawn mower wheel (2) comprises a rim (5). The rim (5) extends from the hub (3) to the tread (4). The rim (5) has a rim width (9) in the axial direction. The rim width (9) corresponds to less than half of the tread width (8), to allow grass clippings to fall from one through opening (7) of the tread (4) to another.

Abstract: A drive hand-control system (6) mainly located at a lawn mower handle arrangement (5) intended for guidance of the lawn mower by an operator, the lawn mower having at least one power unit for driving at least one propulsion member and a cutting member, a drive arrangement for transmitting drive force to the at least one propulsion member and an operator presence control (7) located at the lawn mower handle arrangement (5) preferably for hand engagement by the operator, the drive hand-control system (6) comprising a drive engagement control (8) having at least two positions, where a first position disengages the drive of the at least one propulsion member and a second position engages the drive of the at least one propulsion member, and the drive engagement control (8) being switchable between the at least two positions by the operator, and the first position and the second position of the drive engagement control (8) being stable positions, which are stable without any effort from the operator, except for the
