Claim:
An articulating deck mower comprising a frame unit, first and second cutter decks adapted to cut grass and mounted for movement relative to one another in response to variation in the level of the ground during movement of the mower over the ground, and a deck height adjuster that is coupled to the frame unit and the first and second cutter decks and comprises first and second pivot shafts, a first shaft coupler interconnecting the first and second pivot shafts to allow the first and second pivot shafts to pivot together about their longitudinal axes and to allow the first and second pivot shafts to move to non-parallel positions relative to one another in response to variation in the level of the ground during movement of the mower over the ground, and an actuator arranged to pivot the first and second pivot shafts about their longitudinal axes to cause adjustment of the height of the first and second cutter decks relative to the frame unit in response to actuation of the actuator.
