  • Publication number: 20210307251
    Abstract: A riding lawn care vehicle (10, 310) may include a frame (30, 330), an engine (340, 40), a steering assembly, a support platform (20, 30, 320) and a front platform (348, 48). At least a pair of drive wheels may be operably coupled to the frame (30, 330). The engine (340, 40) is operably coupled to the frame (30, 330) via an engine platform (342, 42). The engine (340, 40) is disposed substantially between the drive wheels to selectively provide drive power to the drive wheels via respective hydraulic pumps (346, 46). The steering assembly includes control levers (50) operably coupled to respective ones of the drive wheels via the respective hydraulic pumps (346, 46). The steering assembly enables steering of the riding lawn care vehicle (10, 310) based on drive speed control of the drive wheels responsive to positioning of the control levers (50).
