Abstract
A riding lawn care vehicle may include a frame, an engine, a steering assembly, a support platform and a front platform. At least a pair of drive wheels may be operably coupled to the frame. The engine is operably coupled to the frame via an engine platform. The engine is disposed between the drive wheels to selectively provide drive power to the drive wheels via respective hydraulic pumps. The steering assembly includes control levers operably coupled to respective drive wheels via the respective hydraulic pumps. The steering assembly enables steering of the lawn care vehicle based on drive speed control of the drive wheels responsive to positioning of the control levers. The support platform is operably coupled to the frame at a rear portion of the lawn care vehicle. The front platform is operably coupled to the frame forward of the engine platform. The front platform supports the hydraulic pumps.
