A riding lawn care vehicle may include a frame, a steering assembly, a first brake assembly, and a first biasing assembly. A first drive wheel and a second drive wheel of the riding lawn care vehicle are operably coupled to the frame. The steering assembly includes a first steering lever and a second steering lever. The first and second steering levers are operably coupled to corresponding ones of the first and second drive wheels via a first hydraulic motor and a second hydraulic motor, respectively, to facilitate turning of the riding lawn care vehicle based on drive speed control of the first and second drive wheels responsive to positioning of the first and second steering levers to control the first and second hydraulic motors. The first brake assembly is operably coupled to the first hydraulic motor to enable a braking force to be selectively applied to a motor shaft of the first hydraulic motor responsive to movement of the first steering lever from an inboard position to an outboard position. The first biasing assembly is configured to positively assist movement of the first steering lever between the inboard and outboard positions in both directions.
