Abstract: A utility vehicle (20) includes a frame (24), a power source (38), and a plurality of steerable structures (40). Ground engaging members (46) are connected to the steerable structures (40). An operator seating area (34) includes a steering control (84) and a speed control (84). Controllers receive input from the steering control and the speed control. Motors drive the ground engaging members (46) at different speeds and in different directions. A controller integrates a steering input with a speed input to effect rotation of the steerable structures (40) and effect rotation of the ground engaging members (46). The steering control, speed control, controllers (86, 88, 90), steerable structures (40), and motors are configured to work together to control the rotational speed of all of the ground engaging members (46) based upon a steering angle input and the lateral side (28, 30) the ground engaging member (46) is connected to. Other examples include braking mechanisms, adjustable track width, and a sealed tubular frame (24, 26).
Abstract translation: 多功能车（20）包括框架（24），电源（38）和多个可转向结构（40）。 地面接合构件（46）连接到可转向结构（40）。 操作员座位区域（34）包括转向控制（84）和速度控制（84）。 控制器从转向控制器和速度控制器接收输入。 电机以不同的速度和不同的方向驱动地面接合构件（46）。 控制器将转向输入与速度输入相集成以实现可转向结构（40）的旋转并且实现地面接合构件（46）的旋转。 转向控制，速度控制，控制器（86,88,90），可转向结构（40）和电动机构造成一起工作以基于转向角输入来控制所有地面接合构件（46）的转速 并且接地接合构件（46）的侧面（28,30）连接。 其他示例包括制动机构，可调节的轨道宽度和密封的管状框架（24,26）。

Abstract: A lawn maintenance vehicle includes an adjustable seat assembly, wherein the seat assembly is rotatable relative to a frame of the vehicle when the vehicle is operated on a sloped surface. The seat assembly is rotatable in order to maintain the operator in a substantially vertical seated alignment while operating the vehicle on a sloped surface. The seat assembly is also rotatable when the vehicle is in a zero-turn or tight-turn maneuver, wherein the seat is rotated toward the center of turning radius to offset the centrifugal forces experienced by the operator during such a maneuver.

Abstract: A walk-behind mower includes a frame and a power source attached to the frame. A selectively steerable drive wheel and a set of follower wheels are rotatably attached to the frame. The walk-behind mower includes a steering wheel assembly attached to the frame, the assembly including a steering column and a steering wheel attached to the steering column. The walk-behind mower also includes a universal joint connecting the steering wheel assembly to the frame. The walk-behind mower further includes a mower deck attached to the frame and a mower blade assembly attached to the deck. In other examples, the walk-behind mower includes a front section and a rear section that rotate relative to each other about a vertical axis. 26 ¾ 4&3 ~'44 0

Abstract: Methods and apparatus for a lawn maintenance vehicle park brake and traction drive interlock are provided. A park brake mechanism is selectively operable between an engaged position and a disengaged position. A traction drive is also mounted to the lawn maintenance vehicle, the traction drive having a disable mode which prohibits transmission of a driving force from the traction drive to a drive wheel. A first operable connection between the park brake mechanism and a wheel brake activates the wheel brake. A second operable connection between the park brake mechanism and the traction drive activates the disable mode of the traction drive. A method of controlling a lawn maintenance vehicle with a park brake and traction drive interlock include the steps of providing a lawn maintenance vehicle, providing an operable park brake mechanism, providing a first operable connection, and providing a second operable connection.
