A mower deck transport lock includes a striker bracket mounted to a rock shaft and extending downwardly and forwardly to engage a height of cut support at any of a plurality of height of cut positions. A transport lock pin positioned adjacent the height of cut support can slide between a first position and a second position. A spring biases the transport lock pin toward the first position and into engagement with the striker bracket to support the mower deck at a transport height above the plurality of height of cut positions. A transport lock disengagement pedal urges the transport lock pin to slide towards the second position to disengage the transport lock pin from the striker bracket.
