Abstract
A zero-turn ('ZT') vehicle is provided with a mainframe and an engine supported on the mainframe to output rotational power. Transaxle systems are provided with each being connected to the engine and to a respective driving wheel such that each transaxle system is configured to translate the rotational power from the engine to the driving wheel. One or more speed control actuators are provided, each being operatively connected to a transaxle system and movable between a minimum position and a maximum position. The speed of a driving wheel is infinitely variable through movement of the speed control actuator. A speed-range control actuator is operatively connected to the transaxle systems and configured to designate one of selectable speed-ranges within which the speed control actuators are permitted to operate. The speed of each driving wheel is determined by a combination of the designated speed-range and a position of the speed control actuator.
