A turf care machine includes a base mounted on a plurality of wheels, a support structure affixed to and extending from the base for supporting a turf machine operator interface, and a hydraulic control system for regulating the speed and direction of the mower. The hydraulic system includes: an engine with a drive shaft; a single hydraulic pump driven by the engine; a first valve set having an inlet connected to the pump outlet; a first hydraulic wheel motor connected to the first valve set; a second valve set connected to the first valve set and to a second hydraulic wheel motor. This drive system has the advantage of using only one pump for driving both drive wheels in a seemingly independent dual path mode of operation, thereby minimizing cost and the number of fluid linkages and parts in such a system.
