ABSTRACT:
The present invention relates to a lawn mower (1), comprising a front mounted mower deck (5) comprising at least one cutting knife, wherein the cutting knife is rotatably arranged in a substantially horizontal plane (10), a wheel suspension arrangement (19) connected to the mower deck (5) and comprising at least one wheel (17) to be in contact with the ground so as to support the mower deck (5) during mowing, wherein the wheel (17) is connected to the wheel suspension arrangement (19) by means of an axle (21) to be in perpendicular alignment with the ground during mowing, and a cutting height adjustment (27) device adapted to move the wheel suspension arrangement (19) with respect to the mower deck (5) for adjusting the mutual height relationship between the wheel (17) and the mower deck (5), so as to adjust the distance between the plane of the cutting knife and the ground. The lawn mower is characterized in that the axle (21) is pivotal about an axis (35) with respect to the wheel suspension arrangement (19) and connected to the cutting height adjustment device (27) in such a way that the axle (21) is parallelly displaced when the wheel suspension arrangement (19) is moved.
