A mechanism for mounting a mower deck to a vehicle, the mechanism including a first member which pivots about a first pivot mechanism as the mower pivots to ride over ground undulations. When raised by the operator, the deck will pivot about the first pivot mechanism until the first member abuts a second member supported by a second pivot mechanism. As the deck continues to be raised it will pivot about the second pivot mechanism. A link coupled between the vehicle frame and the second member causes the second member to also pivot about a third pivot mechanism which swings the deck rearwardly as it is raised.
