A lawn mower comprising a deck (2) mounted on at least two wheel assemblies (4), the deck (2) being mounted on each wheel assembly (4) via a height adjustment mechanism; an interconnecting bar (28) which connects between at least two of the height adjustment assemblies through which movement of one height adjustment mechanism is transferred to the other height adjustment mechanism so that the two height adjustment mechanisms operate in unison; a rack mounted on the interconnecting bar; and a locking mechanism which is capable of co-operating with the rack to hold interconnecting bar stationary relative to the deck, wherein the locking mechanism comprises a pinion (104) rotatably mounted on the deck (2) which meshes with the rack (100) and which is capable of being releasably locked in a plurality of angular positions. The pinion (104) is capable of axially sliding between a first position where it is prevented from rotation movement and a second position where it is capable of freely rotating whilst remaining meshed with the rack (100). The pinion (104) is biased towards the first position and may be moved by a cam mechanism.
