Abstract: A Zero Turn Radius vehicle is provided that utilizes a steering system including front steerable wheels (6, 6a) that is synchronized with a drive system that has dual independent rear drive units (24, 25) to drive the rear wheels (7, 7a) as well as steer the vehicle. The synchronization of the steering system with the drive system allows for true zero radius turning and reduced drag and wear on the vehicle especially the ground engaging wheels (6, 6a, 7, 7a).

Abstract translation: 提供一种零转弯半径车辆，其使用包括前转向轮（6,6a）的转向系统，该前转向轮（6,6a）与具有双独立后驱动单元（24,25）的驱动系统同步以驱动后轮（7,7a） 以及引导车辆。 转向系统与驱动系统的同步允许真正的零半径转动和减少车辆上的阻力和磨损，特别是地面接合轮（6,6a，7,7a）。
