A mower has a frame that supports a rotary cutting deck. A height of cut system is provided for adjusting the height of cut of the deck. In addition, two longitudinal struts and a lateral strut connect between the frame and the rear of the deck. The longitudinal struts propel the deck in forward and reverse directions while the lateral strut provides lateral stabilization to the deck to prevent excessive side-to-side motion of the deck. Each of the struts is a simple elongated rod or bar having a hub at either end that contains a rubber bushing allowing three-axis motion. Each strut is pivotally connected at each hub to corresponding portions of the frame or the deck.
