A cruise control system for a utility vehicle, which is speed-controlled by a hydrostatic transmission, includes a controller having an input for receiving a selectable set speed signal, and an output for sending a speed control signal to at least one proportional valve of a hydrostatic transmission servo control system. The short windows of the first type and the short windows of the second type are then grouped into two preliminary groups based on the window type of each short window. A molding compound layer is disposed on the top surface of the first RDL.
