摘要： A steering system for a mower can include a wheel-specific driving unit for each wheel and a controller for providing control signals to each wheel-specific driving unit to thereby cause each wheel to be independently rotated at a different speed during a turn. By independently rotating each wheel, the mower can complete a turn without damaging the grass. The controller may also provide control signals to cause each steerable wheel to be positioned in a different wheel direction during the turn.
