Abstract

The present invention relates to a lawn mower (1), comprising a chassis (7), a front mounted mower deck (5), and at least one support arm (9) connecting the mower deck (5) with the chassis (7), wherein the support arm (9) is movable with respect to the chassis (7) for lifting the mower deck (5) from a lower position to an upper position, in which upper position the mower deck (5) is tiltable about a horizontal pivot axis (11) with respect to the support arm (9) without interfering with the ground, from a first position in which an underside of the mower deck (5) is directed downwardly, to a second position in which the underside of the mower deck (5) is accessible to an operator standing in front of the lawn mower (1). The lawn mower is characterised in that the centre of gravity (21) of the mower deck (5) is located in front of the pivot axis (11), with respect to the forward direction of the lawn mower (1), when the mower deck (5) is lifted to the upper position.
