摘要： A flexible rotary mower deck lift system includes a center deck having a first end and a second end, and a wing deck pivotably attached to each of the first and second ends. A linear actuator may be actuated to raise and hold each wing deck at a position that is parallel to the center deck, and a lift cylinder may be actuated to raise the center deck and the wing decks together to an intermediate position above a ground surface wherein the center deck and the wing decks are out of contact with the ground surface.

摘要： A zero turning radius mower park brake system includes an over-center pivot member that pivots to a park brake engaged position in response to moving a control arm fully outward, and to a park brake disengaged position in response to moving the control arm fully inward. The control arm is disconnected from the over-center pivot member in the park brake engaged and disengaged positions. An actuator on a lower end of the control arm may contact the over-center pivot member between the park brake engaged and disengaged positions. A biasing spring urges the over-center pivot member to the park brake engaged position and park brake disengaged position.
